WBTC (Wrapped Bitcoin) is an ERC-20 token backed 1:1 by Bitcoin, enabling BTC holders to participate in Ethereum's DeFi ecosystem. This guide explores how WBTC works, its benefits, risks, and why it bridges two of crypto's largest networks.
The Origin of WBTC: Why Wrap Bitcoin?
Bitcoin dominates the crypto market but lacks native smart contract functionality. Ethereum, however, thrives with DeFi protocols and dApps. WBTC emerged to merge Bitcoin’s liquidity with Ethereum’s programmability, creating a seamless cross-chain solution.
How WBTC Works: Tokenization Simplified
- Collateralization:
Custodians like BitGo hold Bitcoin reserves, issuing equivalent WBTC tokens on Ethereum. Minting/Burning:
- Deposit BTC → Mint WBTC
- Burn WBTC → Redeem BTC
- Peg Maintenance:
Regular audits verify 1:1 backing, ensuring trust.

WBTC vs. BTC: Can the Peg Break?
While WBTC aims for a stable 1:1 peg, risks include:
| Risk Factor | Mitigation Strategy |
|---|---|
| Custodian failure | Regular third-party audits |
| Liquidity gaps | Arbitrage traders correct price |
| Transparency concerns | On-chain proof of reserves |
Key Takeaway: WBTC’s peg relies on institutional trust but has maintained stability historically.
