Wrapped Bitcoin: Custody, Ethereum Use, and DeFi Risks

Article OKX Learn

Summary

The document explains WBTC as an Ethereum ERC-20 token intended to represent bitcoin one-for-one. A custodian holds BTC while an equivalent amount of WBTC is minted; redemption burns WBTC and releases the underlying BTC. This structure lets holders use bitcoin value in Ethereum applications, including trading, lending, and liquidity pools. The article also outlines roles for custodians, merchants, and the WBTC DAO, and describes multisignature custody and public reserve information as security measures.

It compares WBTC with native BTC, emphasizing Ethereum smart contract access and the need to rely on a custodial conversion process. It mentions liquidity provision and yield farming as uses, and briefly names renBTC and tBTC as alternatives. These benefits come with risks: users depend on custodians and governance, and face smart contract and operational concerns. The article offers a general overview rather than evidence from independent audits or comparative performance data; its claims about backing and security should be checked against current reserve information.

Key ideas

  • WBTC is an Ethereum token designed to track bitcoin at a one-to-one backing ratio.
  • Minting and redemption depend on BTC custody and corresponding token issuance or burning.
  • WBTC can be used in Ethereum smart contracts and DeFi applications that native BTC cannot directly access.
  • Custodian, governance, and smart contract risks remain despite multisignature controls and reserve transparency claims.
  • Liquidity pools and yield farming are cited as ways to use WBTC, with no performance evidence provided.
