Cross-chain bridge unverified mint pattern
mETH Protocol's assessment for RD-F-106 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Cross-chain bridge tx pattern (deposit src, mint dst without proof). T-09 phase-2 signal tier. Applicable: cmETH LayerZero OFT adapter bridges cmETH between Ethereum L1 and Mantle Network. LayerZero OFT is designed to mint on destination via DVN attestation — not a Nomad-style default-root vulnerability. No unverified mint event reported in public data.
