What Is a ‘Wrapped’ Token and Why Is It Often Used in Token Pairs?
A wrapped token is a cryptocurrency pegged to the value of another crypto asset, usually one that originates on a different blockchain. For example, Wrapped Bitcoin (wBTC) is an ERC-20 token representing Bitcoin on the Ethereum network.
It is used in token pairs to bring assets from incompatible blockchains into a single ecosystem (like Ethereum's DeFi), increasing liquidity and composability.
