Gate is a high‑throughput, multi‑chain bridge that enables the transfer of ERC‑20, ERC‑721, and native assets between Ethereum L1 and several Layer‑2 rollups (Optimism, Arbitrum, zkSync, StarkNet). The platform’s design combines a Merkle‑tree based state commitment, optimistic fraud‑proof verification, and a validator set that is partially permissioned (core validators) and partially permissionless (delegated stakers).
Given the bridge’s size (>$7 B TVL) and
Given the bridge’s size (>$7 B TVL) and its central role in moving capital across ecosystems, it is a prime target for sophisticated adversaries. Our assessment focuses on the smart‑contract layer, validator/consensus mechanisms, cross‑chain messaging, and economic incentives. Overall Risk Rating: 7 / 10 (High‑Medium)
The bridge’s architecture is sound in principle, but
The bridge’s architecture is sound in principle, but several critical and high‑severity issues were identified that could enable asset loss or systemic disruption if left unmitigated. The most pressing concerns are:
