Overview
- Wrapped Bitcoin (wBTC) tokenizes Bitcoin (BTC) into the ERC-20 format.
- It aims to solve liquidity challenges on the Ethereum blockchain.
- Growing interest in DeFi (Decentralized Finance) has increased demand for wBTC.
Wrapped Bitcoin (wBTC) is an ERC-20 token that bridges Bitcoin to the Ethereum blockchain, enabling BTC’s liquidity to integrate with Ethereum’s ecosystem. Users and developers can leverage BTC for decentralized applications (dApps) and smart contracts while maintaining Bitcoin’s price parity (1 wBTC = 1 BTC).
Developed by BitGo in collaboration with Kyber Network and Ren, wBTC supports trading on decentralized exchanges (DEXs) like Uniswap and enhances Ethereum’s financial infrastructure.
How Does Wrapped Bitcoin Work?
wBTC operates similarly to a stablecoin—but without price stability. Instead of fiat backing, wBTC is collateralized by actual BTC reserves held by BitGo. The token’s value mirrors Bitcoin’s in real time.
Key Components:
- DAO (Decentralized Autonomous Organization): Governed by BitGo, Kyber Network, and Ren, the DAO oversees wBTC’s development.
- Custodians: Institutions like BitGo secure the BTC reserves.
- Merchants: Entities (e.g., Curve, Aave, Maker) mint and burn wBTC tokens.
- Users: Trade or use wBTC in DeFi protocols without cross-chain transfers.

Use Cases for Wrapped Bitcoin
- DeFi Integration:
- wBTC enables BTC holders to participate in Ethereum-based lending, yield farming, and liquidity pools.
- DEX Trading:
- Competes with ETH as a trading pair on platforms like Uniswap and Curve.
- Cross-Chain Utility:
- Expands Bitcoin’s functionality beyond its native blockchain.
The Wrapped Token Ecosystem
Beyond wBTC, the Wrapped Token framework standardizes any cryptocurrency into ERC-20 format, fostering multi-asset interoperability. Benefits include:
– Enhanced liquidity for Ethereum.
– Lower transaction costs vs. traditional exchanges.
– Transparency via blockchain explorers.
Key Roles in the wBTC System
| Role | Responsibility | Example Entities |
|---|---|---|
| Custodians | Hold BTC reserves | BitGo |
| Merchants | Mint/burn wBTC | Kyber Network, Aave |
| Users | Trade/use wBTC | Retail/Institutional traders |
| DAO Members | Govern protocol upgrades | BitGo, Ren |
Distribution Process
- A user requests wBTC from a merchant.
- The merchant initiates minting via the custodian.
- BTC is locked, and wBTC is issued (1:1 ratio).
- Burning wBTC releases the underlying BTC.
