token bridge

A token bridge locks assets on the source chain and mints representations on the destination chain.代币跨链桥在源链上锁仓资产，并在目标链上铸造这些资产的映射代币。

Token bridges are among the most exploited protocols in crypto because they hold large concentrated pools of locked assets.代币跨链桥是加密货币中被黑客攻击最多的协议之一，因为它们持有大量集中的锁仓资产池。
