What Is a ‘Wrapped Token’ and Why Is It Necessary in a Multi-Chain Environment?

A wrapped token is a cryptocurrency pegged in value to another cryptocurrency from a different blockchain. For example, Wrapped Bitcoin (wBTC) is an ERC-20 token representing Bitcoin.

It is necessary because it allows non-native assets to be used on a different blockchain's ecosystem, such as using Bitcoin's value in Ethereum's DeFi protocols. This increases liquidity and interoperability across chains.
