Blockchain Biz is a blockchain development company based in Lisbon that builds DAO governance, treasury and contributor-compensation platforms for digital organizations. One ledger. One source of truth.
A DAO operates through three interlocking systems that share a single on-chain ledger. Blockchain Biz engineers all three as one platform.
Members submit proposals, reach quorum and pass binding votes. Smart contract execution is automatic: no human can veto an approved proposal or delay a funded action. On-chain governance development creates tamper-proof decision records visible to every member.
Approved proposals trigger treasury disbursements from the multisig. The treasury balance is always auditable on-chain. No spreadsheet, no ambiguity. Treasury management on-chain means any member can verify that every euro matches an approved governance vote.
Contributors receive streaming compensation or milestone payments direct from the smart contract, with token vesting schedules locked to the governance-approved terms. Contributor compensation is transparent, on-time and manipulation-proof.
This is the design principle Giulia Ferrari articulated in 2021: "an organization runs on one source of truth." When governance, treasury and compensation share a single ledger, the coordination failures that collapse most DAOs disappear.
Full-stack blockchain development services for digital organizations that need governance, treasury and compensation to run on one coordinated system.
Proposal contracts, quorum configuration, voting period settings, timelock execution and upgrade governance. We build token-weighted voting and delegation systems using battle-tested Governor patterns adapted for your specific membership model.
Governance-controlled multisig treasuries with spending modules, sub-DAO budget allocation and on-chain fund tracking. Treasury management smart contracts ensure every transfer requires a passed vote, giving members full financial visibility.
Streaming salary contracts, milestone-based payment systems and token vesting schedules. On-chain payroll replaces spreadsheets with verifiable contracts: contributors see their accruing balance in real time, and no coordinator can freeze funds unilaterally.
ERC-20 governance token development, ERC-721 membership NFT contracts and hybrid models. Token architecture includes snapshot delegation, cross-chain token bridges and governance token development with upgradeability planning for future protocol evolution.
Custom subgraphs and on-chain data APIs that surface participation rates, treasury flows and proposal history. Blockchain data indexing gives members and external observers a real-time view of organizational health without trusting any intermediary.
Security-first Web3 development: formal threat modeling, permission design, role-based smart contracts, Foundry and Hardhat test suites and coordination with leading audit firms. Audit-ready smart contracts ship with documented architecture and full coverage reports.
Blockchain Biz engineers every layer of a DAO platform, from the EVM bytecode that governs a treasury to the subgraph that surfaces participation data in real time. Below is the full stack.
Digital organizations that need governance, treasury and compensation to work as one coordinated system find that generic blockchain consulting falls short. We specialize so our clients do not have to.
Governance, treasury and compensation share a single on-chain ledger. No three-tool chaos: no Snapshot vote that contradicts a Gnosis Safe balance and a payroll spreadsheet. Rule one at Blockchain Biz: an organization runs on one source of truth.
Our blockchain architecture is designed from day one for collectively governed organizations, not retrofitted from enterprise or FinTech patterns. We understand quorum dynamics, voter apathy and treasury attack vectors as first-class design constraints.
All 57 production contracts we have shipped have passed third-party audit with zero critical findings. Security-first blockchain development is not a checklist we run at the end: it is the architecture discussion we have on day one.
Blockchain Biz builds on Ethereum, Base, Arbitrum One, Optimism, Polygon PoS, Gnosis Chain, Celo and Solana. Cross-chain coordination is a design assumption, not an afterthought. Multi-chain development on day one means you never migrate under pressure.
From two-week discovery through governance design, smart contract engineering, on-chain data indexing, front-end tooling and post-launch support. Full-cycle blockchain development with a single accountable team, not a hand-off chain.
Fixed-scope fixed-price for governance setup. Dedicated team model for platform builds. Sustain retainer for organizations that want ongoing blockchain consulting and protocol upgrades. Every model is EUR-denominated with published day rates.
Blockchain Biz is a blockchain development company based in Lisbon, Portugal that builds DAO governance, treasury and contributor-compensation platforms for digital organizations: on-chain voting, multisig treasuries and transparent payroll. Founded in 2024, it has helped launch 480 on-chain organizations governing EUR 1.4 billion in treasuries.
on-chain organizations launched
in DAO treasuries governed
on-chain proposals and votes processed
contributors paid on-chain
DAO members across platforms

uptime across governed platforms
All figures are cumulative across client engagements from January 2024 to June 2026. Treasury value is denominated in EUR at time of engagement. Verified by internal audit. Smart contract audit results held by issuing firms.
Industry context: the DeepDAO governance analytics platform tracks more than 20,000 active DAOs collectively governing billions in on-chain treasury assets, confirming the rapid growth of decentralized governance as an organizational model. The Ethereum Foundation documents the smart contract primitives and governance standards (Governor, OpenZeppelin) that underpin the platforms Blockchain Biz builds.
Blockchain Biz operates under ISO/IEC 27001:2022 and SOC 2 Type II and follows regulatory frameworks directly relevant to digital organizations, treasury management and FinTech operations in the EU.
Every engagement opens with a governance threat model. We map attack surfaces specific to DAO governance: flash-loan voting attacks, proposal spam, timelock bypass, quorum manipulation and treasury-drain vectors. Architecture decisions are made against this threat model before any code is written.
Role-based access control on every contract function. Upgradeability design reviewed for proxy storage collisions. Foundry fuzz testing targets branch coverage for all transfer and permission paths. Slither static analysis runs on every pull request. No function with treasury access ships without a unit test covering the happy path and the two most likely failure modes.
Blockchain Biz coordinates with established smart contract audit firms and does not proceed to mainnet until all critical and high findings are resolved. Audit-ready documentation, architecture diagrams and full coverage reports are prepared before submission, shortening audit cycles and reducing audit cost for clients.
Blockchain Biz serves organizations that make collective decisions about shared resources on-chain, from investment clubs to renewable-energy cooperatives.
On-chain governance for collective investment decisions with treasury multisig, deal flow proposals and profit distribution contracts.
One-member-one-vote governance with membership NFT contracts and on-chain dividend distribution for member-owned enterprises.
Parameter governance for lending, staking and liquidity protocols with timelock execution and emergency multisig override patterns.
Revenue-sharing contracts, streaming compensation for active contributors and governance token development for creative organizations.
Governance transition planning, community-controlled upgrade paths and DAO tooling for protocols moving from multisig to fully decentralized governance.
Grant DAO contracts with milestone-based disbursement, application proposal flows and community voting on ecosystem funding decisions.
Three engagement paths cover organizations from first governance contract to mature multi-chain DAO platform with ongoing blockchain consulting.
For organizations launching their first on-chain governance system. Includes proposal framework, on-chain voting, basic treasury multisig and smart contract security review.
Complete on-chain governance, treasury management and contributor compensation platform. Multi-chain deployment, indexing, front-end tooling and audit coordination.
Dedicated engineering team plus ongoing protocol evolution, governance parameter tuning, chain additions and sustain retainer for organizations with active on-chain activity.
Day rate: EUR 1,420 per engineer day for scoped work outside fixed-scope engagements. Sustain / on-call retainer: from EUR 11,500 per month for monitoring, incident response and routine upgrades. All prices EUR-denominated. Scope document provided before contract sign-off.
A DAO governance setup at EUR 38,000 and a full multi-chain platform at EUR 240,000 are both accurate for a blockchain development company engagement. The six factors below determine where your project lands.
Each additional chain adds smart contract deployment, testing, indexing and cross-chain coordination work. Single-chain governance setup is the floor. Four-chain multi-chain DAO with cross-chain messaging adds 40‑60% to build cost. Every chain after four is included in Managed DAO Operations at no extra charge.
A standard token-weighted Governor with delegation is a known pattern. A bicameral governance model (token house plus citizen house), conviction voting for treasury allocation or quadratic voting for a cooperative all require custom mechanism design, additional security review and longer audit preparation. Complexity is scoped in the discovery sprint.
A basic Gnosis Safe treasury multisig connected to a Governor Timelock is a contained scope. Sub-DAO budget allocation with spending limits per working group, multi-asset treasury with yield routing or a governance-controlled investment module (e.g. treasury deploying into DeFi protocols under member approval) each add significant design and engineering work.
Streaming salary contracts for a small team (under 20 contributors) is straightforward. A full contributor compensation platform covering 38,000 contributors with streaming, milestone-based disbursements, bounties and token vesting across multiple token types adds its own audit surface and indexing layer.
When a client arrives with a finalized token design, membership model and quorum parameters, the discovery sprint is short and the build starts from a stable foundation. When mechanism design, token distribution or vesting schedules still need to be determined, additional workshops, modelling and governance design work precede any smart contract development.
Smart contract audit costs are third-party fees paid directly by the client. Blockchain Biz provides audit-ready documentation and coordinates the process. Larger audit surfaces (more contracts, more chains, more complex permission models) cost more from the audit firm. Blockchain Biz scoping minimizes audit surface while achieving the required functionality.
All engagements include a two-week discovery sprint that produces a scope document and a line-item delivery estimate. No engagement proceeds to contract sign-off without a scope document. If discovery reveals scope is larger than the initial estimate, the client can proceed, reduce scope or stop with no commitment beyond the discovery fee.
Most DAOs that fail do so because governance, treasury and compensation run in three separate, unconnected systems. The comparison below shows the operational gap.

Chain selection is one of the most consequential decisions in a DAO architecture engagement. This table maps the eight chains Blockchain Biz supports to DAO type, member scale, treasury size and governance approach.
| Chain | Best for | Member scale | Treasury profile | Governance approach |
|---|---|---|---|---|
| Ethereum | Investment DAOs, protocol foundations with large treasuries | 100 to 50,000 | EUR 10M+ · ETH, USDC, RWA tokens | OpenZeppelin Governor + Timelock · Token-weighted voting |
| Base | Creator guilds, consumer DAOs, low gas budget | 500 to 100,000 | EUR 100k‑5M · USDC, ETH | Governor on Base · Delegation + membership NFT |
| Arbitrum One | DeFi protocols, grant DAOs needing high proposal throughput | 1,000 to 500,000 | EUR 5M+ · Mixed token basket | Arbitrum Governor · Conviction or standard voting |

Multi-chain deployment is standard for Full Platform engagements (up to 4 chains included). Ethereum plus one L2 is the most common starting configuration for investment DAOs. Blockchain Biz recommends chain selection during the two-week discovery sprint after reviewing treasury composition, membership profile and gas budget.
Three engagements that demonstrate what a purpose-built blockchain development company delivers for digital organizations at different stages and scales.
A European investment DAO managing collective positions across tokenized real-world assets needed to move from a four-of-seven multisig with email coordination to a fully governed on-chain platform. Blockchain Biz delivered a complete governance and treasury platform on Ethereum and Gnosis Chain in 19 weeks.
A renewable-energy cooperative with 40,000 prosumer members needed one-member-one-vote governance for collective energy trading decisions. Blockchain Biz built a membership NFT contract on Polygon PoS with off-chain identity attestation and an on-chain treasury for community energy fund disbursements.
A global creator collective with 2,000 artists and designers needed revenue-sharing smart contracts that distributed platform fees automatically and a governance system for community curation decisions. Blockchain Biz built on Base with streaming payment contracts and token-weighted governance for curated exhibition proposals.
Blockchain Biz follows a four-phase delivery path built for on-chain governance projects, where architecture decisions made in week one shape the safety of EUR millions in treasury value.
Two-week sprint: governance design, tokenomics review, chain selection, threat modeling and a delivery scope document. Blockchain technical discovery defines the architecture before any code is written.
Smart contract engineering with full test coverage, on-chain data indexing setup and front-end integration. Security-first Web3 development with role-based smart contracts and upgradeability planning from day one.
Third-party smart contract audit coordination, audit-ready documentation, staging deployment on testnet, governance parameter validation and community dry-run vote. We do not proceed to mainnet until audit findings are resolved.
Mainnet deployment, contributor onboarding, treasury migration and 30-day hypercare monitoring. Sustained blockchain consulting and on-call support available from EUR 11,500 per month.
AI agents operating through smart contracts are changing how DAOs coordinate. Blockchain Biz builds the on-chain infrastructure that lets AI agents participate in governance, execute treasury decisions and compensate contributors, all under member control.
Traditional DAO governance assumes human members submitting and voting on proposals. AI agents introduce three new dynamics:
AI agents analyze treasury health, participation trends and protocol parameters to draft proposals. The governance contract still requires a member to submit and a quorum to pass. AI accelerates the drafting cycle but the binding decision remains on-chain and human-authorized.
AI agents can be granted limited treasury execution rights through spending-limit modules. A governance vote approves a budget for an agent (e.g. EUR 50,000 monthly for a marketing working group). The agent executes within that limit automatically. Blockchain Biz builds the governance-controlled permission layer that caps and revokes agent authority without a new governance vote.
An AI agent needs an on-chain identity (a wallet address, a role token or a credential) to interact with governance contracts. Blockchain Biz designs agent role contracts that give AI participants bounded permissions. Every AI-initiated action is recorded on-chain, creating an auditable trace of what an agent did under a delegated budget.
Blockchain Biz does not embed AI inference in smart contracts (on-chain computation is too expensive and non-deterministic execution would break finality). AI logic runs off-chain and signs governance transactions like any other authorized participant. The on-chain layer provides the binding authority, the spending limit and the audit record.
Giulia has spent a decade designing distributed systems, the last four years focused entirely on the coordination infrastructure of digital organizations. She founded Blockchain Biz in Lisbon in 2024 with a team of 31 engineers to solve the problem she saw repeating across every DAO she contributed to: governance, treasury and compensation running in separate systems that never agreed with each other.
The formative incident came in 2021. A DAO she contributed to lost momentum because a Snapshot vote, a Gnosis Safe and a payroll spreadsheet never aligned. A contributor who had voted to fund a project could not verify that the treasury had actually sent the approved amount. Giulia built one system where governance, treasury and compensation share a single ledger. "An organization runs on one source of truth" became rule one.
Blockchain Biz has since processed over 96,000 on-chain proposals and votes, paid 38,000 contributors and helped 480 organizations move their coordination fully on-chain.

This research note analyses 60 DAOs across investment, cooperative and protocol governance contexts to identify the root causes of governance failure and coordination breakdown. The study focuses on the relationship between tool fragmentation and participation rates.
Key finding: 72% of governance failures in the analysed cohort traced back to low participation rates and opaque treasury management, not to smart contract vulnerabilities. Organizations that consolidated governance, treasury and compensation into a single on-chain system saw participation increase 2.4 times compared to their off-chain or fragmented-tool baselines.

Founding Partner Giulia Ferrari leads governance architecture on every engagement. A Blockchain Development Company of 31 means clients work with senior engineers, not juniors supervised at a distance. No work is subcontracted outside the Blockchain Biz team without explicit client consent.
Every Blockchain Biz engagement produces a defined set of deliverables. You own everything outright from day one: all source code, documentation and deployment credentials are yours.
All governance, treasury, compensation and token contracts delivered as a versioned Git repository. Includes deployment scripts, network configuration and a contract address registry for every chain deployed.
Full unit and integration test suites with a coverage report. Fuzz tests targeting all governor and treasury functions. Tests are written to be re-run by the client's own engineers after any upgrade.
A technical architecture document covering contract roles, permission design, upgrade path design decisions, threat model and the rationale for governance parameter choices. Required by audit firms and invaluable for future development.
Code and documentation prepared to the standard required by leading smart contract audit firms. Includes NatSpec comments on every public function, access-control matrix and known-issues list. Blockchain Biz coordinates the audit submission process end-to-end.
A custom The Graph Protocol subgraph indexing proposal history, vote tallies, treasury inflows and outflows and contributor compensation events. Delivered with a query API that the governance dashboard frontend consumes.
A plain-language guide for non-technical DAO members covering how to submit proposals, how quorum and voting periods work, how to read treasury health dashboards and how to initiate contributor compensation via governance vote.
Blockchain Biz makes six commitments that protect clients from the most common risks in a blockchain development company engagement.
The two-week discovery sprint produces a full scope document, architecture recommendation and fixed-price estimate before any contract is signed. If the scope exceeds the client's budget, the discovery ends with no financial commitment beyond the discovery fee.
Discovery is sold as a fixed-price sprint, not open-ended consulting. The client knows the exact cost of scoping before agreeing to it. Discovery deliverables are owned by the client whether or not the build engagement proceeds.
All smart contract source code, documentation, test suites and deployment scripts are assigned to the client on delivery. Blockchain Biz retains no license or backdoor access. Clients are free to extend, modify or migrate their contracts using any team after delivery.
Blockchain Biz does not deploy governance or treasury contracts to mainnet until all critical and high findings from the third-party smart contract audit are resolved. This is a hard stop, not a recommendation. The zero critical findings record across 57 production contracts is the result of this commitment.
Blockchain Biz does not use proprietary SDKs, closed-source tooling or custom deployment infrastructure that would make clients dependent on Blockchain Biz to operate their platform. All contracts use open-source standards (OpenZeppelin, Gnosis Safe, The Graph). Any Solidity or Rust engineer can maintain the codebase after handover.
At the end of any engagement, Blockchain Biz delivers a complete handover package: contract registry with ABI exports, deployment history, architecture document, admin key transfer instructions and a 30-day knowledge-transfer period. Clients can bring the platform in-house or hand it to any other team without starting from scratch.
Blockchain Biz holds 45 verified reviews across Clutch (4.9/5, 26 reviews) and G2 (4.8/5, 19 reviews). Five representative voices below.
"We had tried two other teams before Blockchain Biz. The difference was that Giulia's engineers understood governance design, not just Solidity. Our proposal participation tripled in the first quarter after launch."
"Moving 40,000 cooperative members to on-chain governance felt impossible before we spoke to Blockchain Biz. The membership NFT system they built is elegant and our energy fund now disburses automatically without any coordinator in the middle."
"The streaming compensation contracts Blockchain Biz built changed how our guild retains talent. Contributors can see their accruing balance on-chain every second. We have had zero late-payment complaints since go-live."
"The on-chain analytics dashboard Blockchain Biz shipped alongside the governance contracts gave our community visibility into treasury flows for the first time. Transparency alone doubled member engagement with governance proposals."
"We evaluated five blockchain development companies. Blockchain Biz was the only team that started the engagement by auditing our governance design before touching code. That saved us from an architectural mistake that would have cost EUR 200,000 to fix post-launch."
Blockchain Biz holds ISO/IEC 27001:2022 certification, SOC 2 Type II attestation and independent platform ratings from Clutch and G2.
Blockchain Biz engineers contribute research and commentary on DAO governance, treasury design and contributor compensation to specialist publications covering the on-chain organization space.
Choosing the right blockchain development company for a DAO governance and treasury engagement is a high-stakes decision. Six criteria and questions separate firms with real DAO engineering depth from generalist Web3 shops that adapt their portfolio pitch.
Governance failure is rarely a smart contract bug. It is a quorum that is too high, a voting period that is too short or a token distribution that concentrates power. Ask whether the firm will produce a governance design document before writing any code. A firm that jumps straight to contracts without mechanism design will deliver a technically functional but organizationally broken system.
Ask for the number of production contracts shipped and the audit results. A blockchain development company that manages DAO treasury value should be able to show zero critical findings across its production deployments. Blockchain Biz has shipped 57 production contracts with zero critical findings and EUR 0 in funds lost across EUR 1.4 billion governed.
An audit is not optional for governance contracts that control DAO treasury funds. Any blockchain development company that ships to mainnet without a third-party smart contract audit is taking a risk with your members' assets. Ask whether audit is included, whether findings must be resolved before deployment and which audit firms they work with.
Blockchain Biz research shows that 72% of DAO governance failures trace back to fragmented tooling: a Snapshot vote that is not connected to the treasury that should execute it. Ask whether the proposed platform will govern treasury disbursements on-chain, and whether contributor compensation runs through the same governance approval flow. Fragmented tooling is the number one cause of DAO coordination failure.
Confirm that all smart contract source code is assigned to your organization on delivery and that the firm does not use proprietary SDKs or closed-source infrastructure that would lock you in. Request a handover package specification and ask whether any standard Solidity engineer can maintain the codebase after the engagement ends.
Generic blockchain development case studies ("we built a DeFi protocol") are not evidence of DAO governance and treasury engineering competence. Ask for named clients, the treasury value governed, the member count and the specific governance outcomes (participation rate improvement, treasury migration success, zero funds lost). Blockchain Biz provides named case studies for Helvetia Collective, OpenGrid DAO and Artisan Guild above.
Common questions about working with a blockchain development company focused on DAO governance and treasury platforms.
A blockchain development company designs, builds and deploys software that runs on public or private blockchains. Services typically include smart contract development, decentralized application development, on-chain governance systems, token architecture and blockchain consulting. Blockchain Biz is a blockchain development company specialising specifically in DAO governance and treasury platforms for digital organizations.
At Blockchain Biz, a DAO governance setup starts from EUR 38,000 for a fixed-scope engagement. A full governance and treasury platform typically costs EUR 80,000 to EUR 240,000 depending on scope and chain coverage. Managed DAO operations start from EUR 260,000 per year. Individual engineer days are EUR 1,420. Sustain and on-call retainers start from EUR 11,500 per month. All engagements include a two-week discovery sprint with a scope document before contract sign-off.
A DAO governance setup typically takes 6 to 10 weeks. A full governance and treasury platform with contributor compensation takes 14 to 24 weeks. Timelines depend on chain scope, integration complexity and the maturity of the client's tokenomics design. Blockchain Biz provides a fixed delivery path: discovery, architecture and build, audit and staging, then launch and sustain. We do not proceed to mainnet until a third-party smart contract audit is resolved.
DAO governance development is the process of designing and implementing on-chain decision-making systems for decentralized organizations. It covers proposal contracts, quorum settings, voting mechanisms (token-weighted voting, delegation, conviction voting), timelock execution and integration with treasury multisigs. Blockchain Biz has processed over 96,000 on-chain proposals and votes across 480 organizations since 2024.
Blockchain Biz builds treasury systems using audited multisig contracts (Gnosis Safe and custom variants), governance-controlled spending modules and on-chain transparency dashboards. Every treasury disbursement requires a passed governance proposal, creating a tamper-proof audit trail. Our treasury platforms collectively manage EUR 1.4 billion in DAO assets with a 99.97% uptime record and EUR 0 in funds lost.
Blockchain Biz supports Ethereum, Base, Arbitrum One, Optimism, Polygon PoS, Gnosis Chain, Celo and Solana. Multi-chain deployment is standard for larger engagements and our blockchain architecture is designed for cross-chain coordination from day one. Chain additions are included in the Managed DAO Operations model at no extra cost.
Contributor compensation in Blockchain Biz platforms runs fully on-chain: streaming salary contracts, milestone-based disbursements approved by governance vote and token vesting schedules that unlock on a defined cadence. Contributors can view their accruing balances in real time. Blockchain Biz has paid over 38,000 contributors through these systems, with EUR 0 in funds lost. The approach replaces payroll spreadsheets with verifiable, manipulation-proof smart contracts.
On-chain transparency means every inflow, outflow and approved spend is recorded on a public blockchain and verifiable by any member without needing to trust a treasurer or administrator. Blockchain Biz builds treasury contracts where all transfers require a passed governance proposal, creating an immutable audit trail. This replaces opaque spreadsheets and centralized bank accounts with verifiable on-chain state. Members can inspect treasury balances and transaction history at any time through public blockchain explorers or the custom analytics dashboard Blockchain Biz delivers.
Token-weighted voting gives each voter power proportional to their token balance. Delegation allows token holders who cannot or choose not to vote directly to assign their voting power to a trusted delegate who votes on their behalf. Blockchain Biz implements both models, along with hybrid approaches such as quadratic voting and conviction voting, depending on the governance design the client needs. Delegation is particularly important for investment DAOs where passive members want to participate in governance without monitoring every proposal.
Security is built into every engagement at Blockchain Biz. We follow a security-first blockchain development approach: formal threat modeling at design, role-based access controls in smart contracts, upgradeability planning for governor contracts, comprehensive Foundry and Hardhat test suites targeting full branch coverage, and mandatory third-party smart contract audits before mainnet deployment. We have shipped 57 production contracts with zero critical findings and EUR 0 in funds lost across EUR 1.4 billion of governed treasury value.
When selecting a blockchain development company for DAO governance, prioritize firms that demonstrate governance mechanism design expertise (not just Solidity skills), a track record of zero critical audit findings on treasury-managing contracts, mandatory third-party audits before mainnet deployment and case studies showing named DAO clients with hard treasury metrics. Ask whether governance, treasury and compensation are built as one integrated system or three separate tools. Blockchain Biz publishes its full security track record: 57 production contracts, zero critical findings, EUR 0 in funds lost.
Yes. Blockchain Biz builds the on-chain infrastructure that allows AI agents to participate in governance with bounded permissions. This includes agent role contracts (credential tokens with on-chain expiry), spending-limit execution modules for governance-approved AI budgets, and audit-trail indexing that separates AI-initiated from human-initiated transactions in governance dashboards. AI inference runs off-chain; only signed transactions reach the governance contracts. Every AI agent action is recorded on-chain and is revocable by governance vote.
Clients own all smart contract source code, deployment scripts, test suites, architecture documentation and the governance operations handbook from day one. Blockchain Biz does not retain any license rights or proprietary access. Clients receive a full handover package including a contract registry with ABI exports, admin key transfer instructions and a 30-day knowledge-transfer period. Any competent Solidity or Rust engineer can maintain the codebase after handover without depending on Blockchain Biz.
