Threshold Network operates tBTC v2 — the most decentralized 1:1 tokenized Bitcoin — using threshold ECDSA cryptography so no single party can move user BTC across the bridge.
No single signer can move the BTC — only a t-of-n quorum can.
Deposit native BTC into the randomly-selected signer group's wallet. Once a threshold quorum of signers co-signs, the Bridge mints tBTC 1:1 on Ethereum, minus a 0.2% treasury fee.
12 stake-backed signers were randomly drawn from the WalletRegistry. At least 7 must co-sign — a single node holds no key alone.
Native BTC arrives at a deposit address derived for this signing group. The vault stays locked until a quorum signs.
Drag to add co-signers. Below 7-of-12 the action is blocked (red); reach the threshold and the quorum authorizes the move (green).
Fund custody first — there is no BTC for the signers to act on yet.

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.
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.
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.
