Yada Coin

YadaCoin Bridge Infrastructure

Zealynx audited the YadaCoin bridge, a BNB ↔ YadaCoin cross-chain bridge with a KERI-inspired key registry, native and ERC-20 wrapped tokens via beacon proxies, and an ERC-2612 permit-driven operation flow. The 1-week review identified 28 issues including 3 Criticals (zero-cost native drain, broken post-upgrade onboarding, and a permanent key pair registration revert) and 2 Highs (cross-permit msg.value reuse and unvalidated wrapped-token binding). All findings were fixed before mainnet deployment.
