What is Wrapped Token?

Blockchains operate as isolated ledgers; native Bitcoin cannot move directly onto the Ethereum network.

Cross-chain wrapped tokens (like WBTC) lock native BTC with a custodian or bridge contract and mint equivalent tokens on Ethereum.

Native wrappers like WETH convert native ETH into an ERC-20 compliant token so it can interact with automated DeFi smart contracts.

Price parity and 1:1 redemption depend on the security of the backing custodian or smart contract bridge, and wrapped assets carry depeg risk if reserves or bridge contracts are compromised.

Why It Matters in Web3 & Crypto

Wrapped tokens enable cross-chain liquidity and standard token compliance across decentralized finance protocols.

Key Mechanics & Best Practices

  • 1
    Identify 'W' prefix tickers (e.g., WBTC for Wrapped BTC, WETH for Wrapped ETH).
  • 2
    Use wrapped tokens as collateral in DeFi lending protocols or liquidity pools.
  • 3
    Unwrap tokens back to native assets when moving funds back to their origin blockchain.

Practical Scenario

A trader wraps ETH into WETH to trade on a DEX smart contract, or holds WBTC on Ethereum to supply Bitcoin collateral in a DeFi lending pool.
SECURITY & RISK TIP

Always audit the custodian mechanism or bridge contract security model backing any wrapped token before depositing significant capital.
