tBTCtBTC Q4 roadmap: ECDSA signing migrates to FROST Schnorr
Threshold Network laid out tBTC's Q4 roadmap, centered on migrating the bridge from ECDSA signing to FROST Schnorr multisignatures. The change is meant to tighten security, reduce bridge latency, and speed up mint and redemption processing.
The roadmap was announced on Threshold's X account on Oct 5, 2026, with a short video summarizing the planned updates. Additional Q4 items beyond the FROST migration are still being detailed.
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.
