About
Wrapped Bitcoin (WBTC)

Wrapped Bitcoin (WBTC) is an ERC-20 token on the Ethereum blockchain, designed to represent Bitcoin (BTC) on a 1:1 basis, thereby bringing Bitcoin's immense liquidity and value into the decentralized finance (DeFi) ecosystem. Its primary purpose is to enhance interoperability, allowing Bitcoin holders to utilize their digital assets within Ethereum's burgeoning landscape of smart contracts and DeFi applications without selling their BTC. This tokenization of Bitcoin effectively bridges two major blockchain networks, addressing a significant challenge in the crypto space.

The core mechanism behind WBTC involves a federation of custodians and merchants who mint new WBTC by locking up an equivalent amount of actual Bitcoin and burn WBTC to redeem the underlying BTC. This process is transparently verifiable on-chain through a Proof of Reserve system, ensuring cryptographic security and maintaining the crucial 1:1 peg. As an ERC-20 token, WBTC seamlessly integrates with Ethereum's infrastructure, including decentralized exchanges (DEXs), lending protocols, and yield farming platforms, expanding the utility of the original digital asset.

The main function of the WBTC token is to serve as a highly liquid, Bitcoin-backed collateral and trading pair within DeFi. Holders can use WBTC for lending, borrowing, providing liquidity to earn fees, or participating in various yield-generating strategies, all while retaining exposure to Bitcoin's price movements. WBTC has become a foundational element in the DeFi space, acting as a key enabler for cross-chain liquidity and a testament to the innovative potential of tokenization within blockchain technology, significantly expanding the on-chain utility of Bitcoin on other networks.
