Scope

Home · Top · Table of Contents

The audit package covers the Solidity escrow, arbitration, juror registry, reputation registry, deployment scripts, oracle assumptions, test suites, and frontend/API boundaries that submit or display contract state.

Deployment Assumptions

Home · Top · Table of Contents

  • Sepolia remains the active public test network until an external audit report is complete.
  • Mainnet deployments require reviewed constructor parameters, verified source code, deployed dependency addresses, and documented owner/admin authority.
  • Private keys, RPC credentials, API keys, session secrets, and wallet seed phrases must only live in deployment secrets.

Threat Model

Home · Top · Table of Contents

Review escrow custody, unauthorized withdrawals, reentrancy, replayed signatures, oracle staleness, juror manipulation, commit-reveal leakage, minority-vote slashing correctness, deadline edge cases, and frontend/API misuse that could misrepresent on-chain state.

Trust Boundaries

Home · Top · Table of Contents

  • Smart contracts enforce escrow, dispute, payout, rating, and juror behavior.
  • API routes may aggregate public state, but must not custody funds or secrets.
  • Off-chain account services store preferences and encrypted envelopes only.
  • AI providers receive minimized contract metadata only, never raw encrypted documents, private keys, seed phrases, session keys, or unrelated wallet history.

Invariants

Home · Top · Table of Contents

  • Escrowed value cannot be released except through approved, deadline, dispute, cancellation, or warranty paths.
  • Only eligible roles can perform role-specific contract actions.
  • Commit-reveal votes cannot be revealed without the original salt and completion percentage.
  • Hold-back accounting never exceeds the escrow amount.
  • Reputation updates are tied to finalized or completed contract outcomes.

Validation Evidence

Home · Top · Table of Contents

Before sending this package to an auditor, attach current outputs from:

  • npm run hardhat:test
  • npm run foundry:test
  • npm run lint:sol
  • npm run contracts:vendor:check
  • npm run security
  • npm run quality

Known Risks

Home · Top · Table of Contents

  • The final external audit report is not yet present.
  • Mainnet readiness depends on provider secrets, monitoring, and deployment controls outside this repository.
  • Hardhat 3.x migration is complete, but external auditor engagement and a signed final report remain launch-blocking work outside this repository.
  • Maintainers still need to provide the selected independent auditor, signed engagement or audit scope, scope-freeze date, final report, severity list, accepted/rejected finding decisions, remediation owners, and final validation evidence before the Phase 9 audit item can be closed.
