Bridge entity

Meter Passport

Meter Passport is Meter Network's cross-chain messaging and asset-transfer bridge. It is included because a February 2022 false-deposit vulnerability enabled unbacked BNB and WETH minting, caused approximately $4.25 million in direct losses, and led to a compensation program before the bridge was rebuilt and restored.
