Learn all about Wrapped Bitcoin (WBTC), how it bridges Bitcoin and Ethereum, and the benefits it brings to DeFi and blockchain interoperability.
Introduction
Wrapped Bitcoin (WBTC) is a tokenized version of Bitcoin (BTC) that operates on the Ethereum blockchain, representing Bitcoin's value as an ERC-20 token. By converting BTC into WBTC, users gain access to Ethereum-based decentralized finance (DeFi) applications, expanding Bitcoin’s utility beyond its native network.
This article explores how WBTC works, its advantages over traditional Bitcoin, and its role in enhancing blockchain interoperability.
What Is WBTC?
Wrapped Bitcoin (WBTC) is an ERC-20 token pegged 1:1 to Bitcoin. Each WBTC is backed by a real BTC held in reserve by custodians, ensuring transparency and trust.
Key Features:
- Ethereum Compatibility: WBTC operates on Ethereum, enabling integration with DeFi protocols like lending platforms and decentralized exchanges (DEXs).
- Faster Transactions: Unlike Bitcoin, WBTC leverages Ethereum’s faster block times for quicker transfers.
- Interoperability: Bridges Bitcoin’s liquidity to Ethereum’s ecosystem, fostering cross-chain utility.

Who Created Wrapped Bitcoin?
WBTC launched in January 2019 through a collaboration between:
- BitGo: Manages BTC reserves for WBTC collateralization.
- Kyber Network: Facilitates decentralized liquidity and token swaps.
- Ren Protocol: Focuses on cross-chain asset interoperability.
Governed by the Wrapped Tokens DAO, WBTC ensures decentralized oversight while maintaining security and transparency.
How Does WBTC Work?
The Wrapping Process:
- Deposit BTC: Users send Bitcoin to a custodian’s verified address.
- Mint WBTC: The custodian locks the BTC and issues an equivalent WBTC amount on Ethereum.
- Unwrap WBTC: To redeem BTC, WBTC is burned, and the custodian releases the reserved Bitcoin.
All transactions are recorded on-chain for public verification.
Benefits of Wrapped Bitcoin
1. DeFi Accessibility
WBTC unlocks Ethereum’s DeFi ecosystem for Bitcoin holders, enabling:
- Yield farming
- Liquidity provision
- Collateralized lending
2. Improved Liquidity
WBTC deepens liquidity pools on DEXs like Uniswap, easing BTC-backed trading.
3. Cross-Chain Interoperability
Bridges Bitcoin and Ethereum, combining BTC’s store-of-value with Ethereum’s smart contract flexibility.
4. Faster Transactions
Ethereum’s shorter block times make WBTC transfers quicker than Bitcoin’s network.

WBTC vs. Bitcoin: Key Differences
| Feature | WBTC (ERC-20) | Bitcoin (BTC) |
|-----------------|---------------------------|---------------------------|
| Blockchain | Ethereum | Bitcoin |
| Speed | Faster (Ethereum-based) | Slower (Bitcoin-based) |
| DeFi Access | Full integration | Requires bridging |
| Governance | DAO-supervised | Fully decentralized |
FAQs
1. Why use WBTC instead of Bitcoin?
WBTC allows Bitcoin holders to participate in Ethereum’s DeFi ecosystem, earning yields or trading on DEXs without selling BTC.
2. Is WBTC safe?
Yes, WBTC is audited and fully backed by reserved BTC. Transactions are transparently recorded on Ethereum.
3. How do I convert BTC to WBTC?
Deposit BTC to an authorized custodian, which mints WBTC. Reverse the process to redeem BTC.
4. Can WBTC’s price deviate from Bitcoin?
WBTC aims for a 1:1 peg, but minor price differences may occur due to market demand.
5. What are WBTC’s risks?
Dependence on custodians and smart contract vulnerabilities are potential risks, though audits mitigate these.
6. Where can I trade WBTC?
WBTC is available on major exchanges and DeFi platforms like Uniswap and Aave.
Conclusion
Wrapped Bitcoin (WBTC) revolutionizes Bitcoin’s utility by linking it to Ethereum’s DeFi landscape. Whether for yield farming, faster transactions, or cross-chain interoperability, WBTC offers a versatile solution for crypto investors.
