No open critical findings
Summary
Echo Bridge protocol is an IOTA Ethereum bridge solution. The protocol enables cross-chain bridging and communication between the IOTA blockchain and EVM compatible chains. Its primary goal is to support bidirectional token bridging, allowing users to move assets seamlessly between chains using a validator committee for message verification. The system ensures trust-minimized operations through threshold-based signature approval, nonce-based replay protection, and committee governance. ERC20 tokens can be locked on the EVM side and minted as wrapped assets on IOTA, and vice versa.
