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.
