The Problem
Bringing BTC into DeFi has historically required trusting a centralized custodian (e.g. BitGo for WBTC) — a single key holder can freeze, blacklist, or lose every wrapped Bitcoin in circulation.
The Solution
tBTC v2 replaces the central custodian with a randomly assigned threshold-ECDSA signing group of stake-backed nodes; no individual signer holds the BTC key, and signers are slashable for misbehavior.
Why it Matters
Most decentralized BTC bridge in production (largest TVL among permissionless wrapped BTC issuers), native BTC redemption with no lockup, no pause/blacklist functions, multi-chain via Wormhole + CCIP.
