Six cross-chain protocols mapped as a trust topology. Each connects Ethereum to other chains — but their security assumptions span multi-sig keys to ZK consensus proofs. Tap a protocol to see its trust threshold, verification gas, and hack history.
Cross-chain bridges have lost $2.5B to hacks because receiving contracts accept messages they cannot cryptographically verify. AI agents operating across chains inherit this exact problem. Here are the four trust models, their real security parameters, and a principled agent policy.
