Bitcoin remains the largest, most renowned, and pioneering cryptocurrency to date. Its emergence spurred groundbreaking technologies, including Ethereum—a platform fostering innovation in decentralized applications (dApps) and smart contracts.
Among these advancements is Decentralized Finance (DeFi), a system revolutionizing crypto transactions with trustless financial tools. Within this ecosystem, Wrapped Bitcoin (WBTC) was born—an ERC-20 token representing Bitcoin on the Ethereum blockchain.
WBTC bridges Bitcoin’s liquidity and value into DeFi, enabling BTC holders to participate in Ethereum’s dynamic financial landscape.
What Is Wrapped Bitcoin (WBTC)?
WBTC is an ERC-20 token pegged 1:1 to Bitcoin. It allows seamless conversion between BTC and WBTC, offering faster Ethereum-based transactions. Launched in January 2019, WBTC resulted from collaborations among DeFi leaders like BitGo, Kyber, and MakerDAO, governed by the WBTC DAO.
Advantages of Wrapped Bitcoin
1. Ethereum Wallet Integration
WBTC integrates with Ethereum wallets, granting access to:
- Decentralized applications (dApps).
- Smart contracts.
- Over 280,000 circulating WBTC tokens.
2. Enhanced Liquidity for DeFi
DeFi platforms like Compound and MakerDAO require collateral. WBTC unlocks Bitcoin’s liquidity, enabling:
- Larger borrowing/lending pools.
- Cross-chain utility without selling BTC.
3. Transparent Audits
WBTC ensures trust via:
- Regular third-party audits.
- Public on-chain verification of BTC/WBTC reserves.
How WBTC Works
Minting WBTC:
- User Request: Submit BTC to a WBTC merchant.
- Custodian Action: The custodian locks BTC and mints equivalent WBTC.
- Token Issuance: WBTC is delivered to the user’s Ethereum wallet.
Redeeming BTC:
- Burn WBTC: Initiate a burn request.
- BTC Release: Custodian unlocks BTC proportional to burned WBTC.
WBTC vs. Bitcoin: Which to Choose?
| Feature | Bitcoin (BTC) | Wrapped Bitcoin (WBTC) |
|------------------|---------------|------------------------|
| Blockchain | Bitcoin | Ethereum (ERC-20) |
| Use Case | Store of value | DeFi integration |
| Transaction Speed | Slower | Faster |
Choose BTC for long-term holding. Opt for WBTC to engage with DeFi protocols.
Where to Acquire WBTC?
Purchase WBTC on:
- Decentralized exchanges (Uniswap, SushiSwap).
- Centralized platforms (Coinlist, Poloniex).
