What is the YB cbBTC Pool?
The YB cbBTC pool is a Curve Finance yield-bearing pool for Coinbase's wrapped Bitcoin (cbBTC) on Ethereum. Curve's yield-bearing pools are designed to pair wrapped or synthetic versions of the same underlying asset, enabling efficient trading with minimal slippage.
Understanding cbBTC
cbBTC is Coinbase's wrapped Bitcoin token on Ethereum. Each cbBTC is backed 1:1 by Bitcoin held in Coinbase custody. As of 2025, Coinbase selected Chainlink's Cross-Chain Interoperability Protocol (CCIP) as the exclusive bridging solution for cbBTC.
cbBTC is a fully custodial token, meaning:
- Coinbase is the sole issuer and custodian
- Bitcoin backing is held in Coinbase's custody infrastructure
- Token supply depends on Coinbase's operational continuity
How This Pool Works
The pool enables trading between cbBTC and other Bitcoin-pegged assets in Curve's ecosystem. Using StableSwap mathematics optimized for similarly-priced assets, the pool maintains tight spreads even for large trades.
Liquidity providers deposit cbBTC and receive LP tokens representing their pool share. They earn trading fees generated when users swap through the pool.
Fee Earnings and APY
The displayed 0.26% APY reflects trading fee income. This relatively low APY is typical for Bitcoin pools, which generally see less trading volume than stablecoin or ETH pools. Additional CRV emissions may boost returns if the pool has an active gauge.
Impermanent Loss Considerations
Since the pool pairs assets pegged to Bitcoin's value, impermanent loss is minimal under normal conditions. The primary risk is if cbBTC depegs from Bitcoin, which could occur due to:
- Coinbase custody issues
- Regulatory actions affecting Coinbase
- Bridge vulnerabilities
Risks
- Custodian Risk: cbBTC relies entirely on Coinbase custody and operations
- Regulatory Risk: As a centralized custodian, Coinbase is subject to regulatory actions
- Smart Contract Risk: Curve protocol vulnerabilities
- Depeg Risk: If cbBTC trades below Bitcoin value, LPs may experience losses
- Low Yield Risk: APY may not compensate for opportunity cost of holding Bitcoin
