tBTCtBTC bridge resumes onchain after security maintenance
Threshold Network paused new BTC deposits/tBTC minting and redemption requests as a precaution while security maintenance on the tBTC bridge was completed. During the pause, updates on November 2, 4, and 6, 2026 said tBTC remained fully backed — approximately 4,320 BTC in bridge wallets against roughly 4,185 tBTC in circulation — with no unauthorized minting or BTC movement; reserves can be verified on-chain.
On November 8, 2026, Threshold confirmed the bridge has resumed onchain following completion of the maintenance. Node operators are reconnecting on patched systems, and the bridge will return to full operation as more come back online.
- Redemption requests and deposits made before the pause remain safe and will be processed as operators reconnect.
- The bridge UI will be re-enabled once enough operators are online to process deposits, mints, and redemptions promptly.
- Until the UI is back, users are asked not to send BTC to previously generated deposit addresses or resubmit pending transactions; new deposits should use a fresh address.

tBTC
tBTC is a decentralized wrapped Bitcoin that is 1:1 backed by main-net BTC. Unlike other wrapped Bitcoins, the BTC that backs tBTC is not held by a central intermediary, but is instead held by a decentralized network of nodes using threshold cryptography.
tBTC is trust minimized and redeemable for main-net BTC without a centralized custodian. It can be used across the entire DeFi ecosystem.
tBTC can be used as collateral, liquidity, a store of value, and can be integrated with DeFi apps across all blockchains.
As with other BTC wrappers, tBTC provides cryptocurrency traders and general users with a non-volatile BTC token, that can be used to generate yield whilst holding main-net BTC.
