ION Contract Audit
Scope
Use this skill for all smart contract work in ION DEX:
- ION FunC contracts.
- BSC/EVM Solidity contracts.
- AMM, swap, liquidity, staking, burn, bridge, vault, treasury, fee, relayer, oracle, and sentinel logic.
Required Security Checklist
Before calling a contract change complete, check:
- Reentrancy and callback ordering.
- Integer overflow, underflow, rounding, precision loss, and dust handling.
- Access control, ownership transfer, roles, emergency pause, multisig, and timelock.
- Replay protection, nonce handling, chain ID, order ID, and signature domain separation.
- Oracle manipulation, stale price, TWAP, CMC/off-chain trust assumptions, and flash-loan exposure.
- MEV, sandwiching, front-running, slippage, price impact, and commit-reveal where needed.
- Token compatibility issues: fee-on-transfer, rebasing, non-standard ERC-20 return values, Jetton transfer notifications.
- Bridge consistency: source event, relayer quorum, destination mint/release, rollback, stuck funds.
- Event completeness for off-chain indexers and audits.
- Gas/storage layout and unbounded loops.
- Admin key management and hardware wallet assumptions.
ION Official Source Discipline
For ION-native work, load ion-official-source and inspect D:/openclaw-tools/ion first. Do not invent ION-specific primitives without checking official references.
Security Framework Discipline
Before contract, bridge, treasury, staking, burn, oracle, or sentinel work, read .memory-bank/security-audit-and-stress-framework.md and docs/23-security-audit-and-stress-sandbox.md, then run node scripts/security-preflight.mjs when shell access is available.
Testing Requirements
Contract work must eventually include:
- Unit tests for normal, boundary, and revert cases.
- Integration tests for swap/liquidity/staking/bridge flows.
- Fuzz/property tests for invariants.
- Gas snapshots for hot paths.
- Formal or semi-formal invariant notes for critical accounting.
- Pressure, gas, or chaos sandbox evidence for completed high-risk flows.
Until the contract test harness exists, mark contract features as design-only and do not claim production readiness.
Output Format
For reviews, lead with findings by severity, then assumptions, then required tests. Do not bury security issues in summaries.
