@decodeficrypto @gluk64 USDC is a bit different, as the asset can be redeemed off both chains via Circle. So the IOU point is actually off-chain, rather than in the bridge.
If you bridge a token that's native to one chain, eg ETH, you get an IOU that always relies on bridge security.
@gluk64 USDC的decodeficrypto有点不同，因为资产可以通过Circle从两条链上赎回。所以欠条点实际上是链外的，而不是桥上的。
如果您桥接了一条链（例如ETH）固有的令牌，您将获得一个始终依赖于桥接安全性的IOU。
