Wrapped Tokens

Wrapped tokens are synthetic representations of assets from one blockchain that exist on a different blockchain, typically maintaining a one-to-one peg with the original asset through smart contract escrow or minting mechanisms. When a user wraps an asset, the original is locked or burned while an equivalent token is created on the destination chain, preserving the asset's economic value while enabling its use in different DeFi ecosystems, applications, and liquidity pools. Wrapped tokens are essential for cross-chain capital efficiency but introduce counterparty risk since the wrapping mechanism must reliably maintain the peg and prevent double-spending. Example: Wrapped Bitcoin (wBTC) locks Bitcoin in a custodian contract and mints equivalent ERC-20 tokens on Ethereum, allowing Bitcoin holders to access Ethereum DeFi without selling their BTC, though requiring trust that the custodian maintains the 1:1 backing. Why it matters for cross-chain interoperability: Wrapped tokens enable instant capital redeployment across chains without forced asset sales, but their trustworthiness directly determines whether users can confidently move value between ecosystems or face hidden counterparty risks.
