Cross-chain bridge unverified mint pattern
Usual (USD0 / bUSD0 / USUAL)'s assessment for RD-F-106 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
USD0 is a LayerZero OFT with L1 lock-and-mint to Arbitrum/Base/BNB Chain. A forged lzReceive message could mint unbacked USD0 on a destination chain if DVN is misconfigured (1/1). DVL is almost entirely on Ethereum (100% per DefiLlama), suggesting L2 OFT mints are minimal in volume. Cross-chain bridge mint-without-proof monitoring requires live LayerZero event indexing — not implemented in current pipeline. DVN config also not verified (dvn_configs = []).

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