Overview
Wrapped Bitcoin (WBTC) is an ERC-20 token representing Bitcoin (BTC) on the Ethereum blockchain. Launched in January 2019, WBTC aims to bring the liquidity and value of Bitcoin to the Ethereum ecosystem, enabling Bitcoin holders to participate in decentralized finance (DeFi) applications. Each WBTC token is backed 1:1 by Bitcoin, providing a stable and transparent bridge between the two blockchains.
Key Features
• Bitcoin Backing: Each WBTC token is fully backed by an equivalent amount of Bitcoin, ensuring its value is pegged to Bitcoin.
• Interoperability: WBTC allows Bitcoin holders to access Ethereum-based DeFi applications, enhancing their liquidity options.
• Transparency: The WBTC reserve is fully audited and verifiable on the blockchain, ensuring trust and transparency.
• DeFi Integration: WBTC is widely used in DeFi applications, including lending, borrowing, and yield farming.
Technology
• Ethereum Blockchain: WBTC is an ERC-20 token, leveraging Ethereum’s smart contract capabilities and infrastructure.
• Custodian Model: Bitcoin is held in custody by trusted partners, and WBTC is minted or burned based on Bitcoin deposits and withdrawals.
• Smart Contracts: WBTC uses smart contracts to manage token minting, burning, and transferring.
Market Performance
• Historic Price Trends: WBTC’s price closely tracks the price of Bitcoin, with minor deviations due to market demand and supply.
• Market Capitalization: WBTC’s market cap has grown significantly, reflecting its adoption and the increasing use of Bitcoin in DeFi.
