# Quip Network security audit

Quip Network, built by Postquant Labs, brings post-quantum security to Ethereum smart contract wallets; this audit covered three repositories: a UUPS-upgradeable wallet authenticated by post-quantum SHRINCS signatures, a library of hash-based signature verifiers implementing WOTS+, SHRINCS and SPHINCS+C, and a singleton escrow contract for hashlocked same-chain and cross-chain swaps.

Codezen audited Quip Network together with Oak Security. Technologies in scope: Solidity, Ethereum, EVM, Cryptography and Post Quantum. We reported 48 findings: 9 major, 17 minor and 22 informational.
