What is the tBTC/WBTC Pool?
The Curve tBTC/WBTC pool facilitates trading between two wrapped Bitcoin tokens: Threshold Network's tBTC and BitGo's WBTC. This pool provides essential liquidity for the decentralized Bitcoin bridging ecosystem.
Understanding the BTC Wrappers
tBTC (Threshold Network):- Decentralized Bitcoin bridge
- Backed 1:1 by BTC held in threshold cryptography
- No centralized custodian
- Merger of Keep Network and NuCypher (Threshold)
- Centralized wrapped Bitcoin by BitGo
- Most liquid BTC on Ethereum
- Custodial model with verified reserves
- Industry standard for BTC in DeFi
Decentralized vs. Centralized
This pool bridges two philosophies:
- tBTC: Decentralization-focused, trust-minimized
- WBTC: Liquidity-focused, centralized custody
Users can choose their preferred trust model.
