// Case study
ERC-20 governance token, audit prep and test coverage uplift
Third-party audit found four medium issues pre-mainnet, Ownable misuse, snapshot gaps, and unchecked mint caps fixed before launch.
A DAO tooling startup prepared an ERC-20 with on-chain voting hooks for mainnet. Internal tests covered ~70% of lines but lacked formal audit trail, threat modeling, and gas profiling on delegation paths.

Client context
A DAO tooling startup prepared an ERC-20 with on-chain voting hooks for mainnet. Internal team had 70% test line coverage but no formal audit trail.
Our approach
Simplileap engagement: threat model workshop; Slither + Mythril runs; Hardhat test suite expansion; gas profiling on vote delegation paths; audit documentation pack for external firm.
Delivery notes
Issues caught pre-audit: mint function missing cap check in one inheritance branch; snapshot not updating on transfer in edge case; central admin could pause transfers without timelock, replaced with OpenZeppelin TimelockController pattern.
External audit (partner firm) returned zero critical, one low informational post-fix.
The challenge
Problems: tokenomics required retroactive allocation script, audited separate Merkle distributor contract; deploy script used wrong chain ID in test, CI guard added.
Results & impact
Outcome: mainnet deploy on schedule; $12M FDV launch with no post-deploy contract incidents in first 90 days. Project anonymized, DAO infrastructure.
