Cross-chain bridge unverified mint pattern
Ethena'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 #
Ethena uses LayerZero OFT — lock-and-mint model where USDe/sUSDe is locked on source chain and minted on destination via DVN verification. Post-KelpDAO upgrade to 4-of-4 DVN significantly raises the bar for forged-message attacks (would require compromising 4 independent DVNs simultaneously plus RPC poisoning). Rate limit of $10M/hour per chain limits potential damage even if an attack were attempted. No anomalous cross-chain minting events detected.

Methodology #
Detect cross-chain activity consistent with an unverified mint on the destination chain (deposit on source without corresponding verified proof on dest).
