Smart contract development and audit agreement
In a blockchain project, an error may become public, exploitable and difficult to remedy. The agreement must define the economic specification, threat model, testing, audit and authority over upgrades or emergency shutdown.
Technical and economic specifications
The agreement describes functions, states, permissions and economic invariants. DeFi specifications define assets, calculations, liquidation, fees and extreme scenarios; NFT specifications define minting, supply and metadata.
The network, compiler, libraries and standards are versioned. Oracles, bridges and off-chain services are treated as dependencies with their own risks.
Testing, audit and acceptance
An audit must not be presented as an absolute guarantee. The agreement separates responsibilities of the developer, auditor and team deciding deployment.
- Unit tests, integration tests and negative scenarios.
- Static analysis, fuzzing and network-specific checks.
- Threat model and assumptions about oracles and liquidity.
- Independent audit and treatment of findings by severity.
- Launch conditions and acceptance of residual risks.
- Bug bounty, monitoring and incident procedure.
Admin keys, upgrades and incident response
Terms must show who holds keys, how many signatures are required and what each role can change. Upgradeable proxies, timelocks and pause functions are control mechanisms requiring documentation for users.
Incident procedures establish notification, coordination, shutdown, public communication and remediation. If rollback is technically impossible, the agreement must not promise it.
IP, open source and applicable regulation
The agreement addresses code rights, open-source licences, module reuse and repository publication. We check whether the developer can transfer or license every delivered component.
The Data Act contains requirements for smart contracts executing data-sharing agreements, not every blockchain code. The Cyber Resilience Act and other security rules may matter depending on how software is marketed. Token and service classification under MiCA is analysed separately.

- 04Implementation and review
We deliver the final version, priority actions and reference points to monitor as products or legislation change.
Frequently asked questions
Does an audit guarantee the smart contract will not be exploited?+
No. It reduces risk within the scope and methods used. The agreement must describe these limits and the remediation process.
Is the developer liable for every on-chain loss?+
Liability depends on cause, obligations, control, audit, client contribution and valid negotiated limits. A total exclusion is not automatically effective.
Who should hold admin keys?+
This is a governance and risk decision. The agreement must document holders, multisig threshold, rotation, recovery and transparency towards users.
