## Bridge Liquidity Drain Risks

Bridge liquidity drain risks occur when the pooled assets on a destination chain are removed by unauthorized users exploiting vulnerabilities in the bridge protocol. This often happens through minting unauthorized wrapped tokens and immediately swapping them for native liquidity in decentralized exchange pools linked to the bridge.

Because these pools rely on the bridge to provide the liquidity for the wrapped assets, the drain depletes the reserves of the protocol. This risk is exacerbated by the speed of automated market makers, which can facilitate massive outflows before protocol security teams can intervene.

Managing this risk requires circuit breakers, rate limiting on minting, and transparent collateral monitoring.
