WBTC (Wrapped Bitcoin)
About
WBTC is a wrapped Bitcoin token that enables Bitcoin to be used across multiple blockchain networks in decentralized finance. It maintains 1:1 Bitcoin backing through secure custody and transparent proof-of-reserves, making Bitcoin composable in DeFi ecosystems while preserving its original value proposition.
Where Does Yield Come From?
WBTC is a wrapped version of Bitcoin that lets you use Bitcoin in decentralized finance (DeFi) apps. WBTC itself doesn't create yield; it's a tool that lets Bitcoin earn yield through DeFi.
You can earn yield by using your WBTC in various DeFi services:
- As collateral for loans on platforms like Aave, JustLend, and SparkLend.
- By supplying liquidity to trading pools on exchanges like Uniswap, Curve, and Orca.
- Through automated yield strategies on aggregators like Convex, Beefy, and Yearn.
WBTC is backed 1:1 by real Bitcoin held in secure custody by BitGo, with multi-key security and public proof of reserves.
The yield you earn comes from the DeFi platforms you use—through interest, trading fees, and reward programs. WBTC simply represents your Bitcoin across many blockchains, including Ethereum, TRON, Solana, Base, Kava, and Osmosis.

Backers
WBTC was launched in 2019 as a multi-institutional consortium project rather than through traditional venture capital funding. According to the official whitepaper, the initial institutional participants included BitGo as the custodian holding the Bitcoin reserves, with Kyber Network and Republic Protocol serving as the initial merchant partners for distribution. The project operates under a DAO governance model where custodians and merchants are DAO members. No specific funding rounds, investment amounts, or venture capital investors are disclosed on official sources.
