How do cross-chain bridges move coins to another chain?
WBTC is a wrapped token on Ethereum pegged to Bitcoin. Each WBTC is backed by 1 Bitcoin held by a custodian.
Cross-chain transfers involve an extra layer of trust compared with transfers on the same chain: in addition to trusting the two chains themselves, you also have to trust the bridge’s smart contract code and verification mechanism.
$ZRO and $W are the tokens of the cross-chain messaging protocols LayerZero and Wormhole, respectively.
