Introduction to WBTC
Wrapped Bitcoin (WBTC) is an ERC-20 token backed 1:1 by Bitcoin, enabling BTC holders to participate in Ethereum-based decentralized finance (DeFi) applications. Launched in January 2019 through a collaboration between Kyber, Ren, and BitGo, WBTC combines Bitcoin's stability with Ethereum's smart contract capabilities.
Key Features:
- 1:1 Bitcoin backing: Each WBTC is redeemable for one BTC.
- Cross-chain functionality: Use BTC on Ethereum, TRON, Solana, and other smart contract platforms.
- Transparency: Reserve proofs and on-chain transactions ensure accountability.
How WBTC Works
Minting and Redeeming Process
Minting WBTC:
- Users send BTC to a merchant custodian.
- Custodian locks BTC in reserves and mints equivalent WBTC on Ethereum.
Redeeming BTC:
- WBTC is burned on Ethereum.
- Custodian releases locked BTC to the user.

Benefits of WBTC
1. Expanded Utility for Bitcoin
- Enables BTC usage in DeFi protocols (lending, staking, DEXs).
- Avoids selling BTC for lesser-value tokens.
2. Faster Transactions
- Settles in ~15 seconds (Ethereum block time) vs. 10 minutes for Bitcoin.
3. Earn Passive Income
- Stake WBTC on PoS networks like Ethereum post-Merge.
Technical Considerations
Security Model
- Custodial risk: Relies on trusted entities (e.g., BitGo) to hold BTC reserves.
- Decentralized alternatives: Prefer non-custodial bridges where possible.
Recent Developments
- BitGo partnered with BiT Global for multi-jurisdictional custody (August 2025).
- TRON founder Justin Sun affirmed strategic but non-controlling involvement.
