Wrapping involves creating a tokenized version of an asset on a different blockchain, like Wrapped Bitcoin (WBTC) on Ethereum. The original asset is locked, and the wrapped version is issued on another blockchain.
Bridging connects two blockchains directly, allowing assets to be transferred between them. Instead of creating a tokenized version, the original asset is typically locked on one chain, and an equivalent asset is minted on the other chain. The bridge ensures the transfer happens across chains.
So, while wrapping creates a token for use on another blockchain, bridging facilitates direct transfer between blockchains without creating a new token.
