Protocol Specification & Economic Design
Formal capture of system behaviour, trust assumptions, incentive structures, and adversarial scenarios. Includes economic modelling for tokenised mechanisms and equilibrium analysis under stress.
Secure systems, specified before they are written.
Audicity designs and delivers smart contract systems engineered for long-term operational integrity. Every engagement begins with formal specification and threat modelling, not code.
Specification first. Implementation second.
The most consequential decisions in any smart contract system are made before a single line of code is written. We begin every engagement by capturing the system’s intended behaviour, its trust assumptions, and the threats it must withstand under adversarial conditions.
This work produces a formal specification that informs architectural choices, governs implementation, and serves as the reference for verification. It also creates the conditions for predictable delivery, since the scope of work is defined by what the specification requires rather than by what surfaces during development.
Once specification is complete, we move into implementation against documented coverage thresholds, peer review at every stage, and continuous static analysis through the build pipeline.
What an engagement covers.
Contract Development
EVM-native engagements in Solidity and Vyper, against documented coverage thresholds, with peer review at every commit. Patterns selected for clarity, gas efficiency, and long-term maintainability.
Verification & Testing
Static analysis, fuzzing, invariant testing, and where appropriate, formal verification. Tooling includes Foundry, Echidna, Slither, Mythril, and Certora. Coverage targets and verification scope are defined in the specification phase.
Deployment & Operational Handover
Upgrade pattern selection, multisig and timelock configuration, deployment scripting, and structured operational handover. Documentation produced is operational reference, not retrospective justification.
Engineering discipline, applied without exception.
- Test coverage above 95% at branch level on critical paths, verified through automated CI.
- Static analysis on every commit. Slither, Mythril, and custom rule sets integrated into the build pipeline.
- Independent peer review at architecture, implementation, and pre-deployment stages.
- Formal verification of critical invariants where the stakes warrant the investment.
- Documented incident response procedures handed over with every deployment.
- Post-launch operational support available under continuing engagements.
Begin an engagement.
Smart contract architecture engagements are scoped against the specification phase and progress through defined milestones. To begin, brief us on the system you are building, the threats it must withstand, and the constraints under which it will operate.
