Users send ETH ICE to the bridge contract on ETH, which locks the tokens. Anyswap bridge mints and releases a wrapped version of the same token on FTM, sending it to the user wallet on FTM. Bear in mind that those two tokens have the same address, but this might not always be the case! For every FTM ICE in circulation, there is one ETH ICE locked in the bridge! This allows us to easily track the circulating supply, as all the tokens on every different chain have 1 token locked on the native chain (In our case Ethereum)!
