OFT Sentinel

Checks 1–7

OFT Sentinel checks whether a LayerZero cross-chain token (OFT) is configured safely before funds move. Use before bridging, listing, or integrating any OFT. Send the config as JSON: routes with each destination's DVNs and confirmations; address and chainId optional. Returns a deterministic verdict in under a second: 0-100 score, PASS / AT_RISK / CRITICAL, plain-language findings with fixes. Omitted fields are never scored against you. No AI in the verdict path - same config, same answer.
