tBTC (ticker: TBTC) is a decentralized, tokenized version of Bitcoin that lives on Ethereum. Every tBTC in circulation is backed 1:1 by real BTC locked on-chain, which lets Bitcoin holders use their coins in Ethereum's DeFi ecosystem without selling them or trusting a single custodian. The system is run by the Threshold Network, a decentralized group of stakers rather than a company.
Frequently asked questions
What is tBTC and how is it different from regular Bitcoin?
tBTC is an ERC-20 token on Ethereum that represents Bitcoin one-to-one, while the actual BTC stays on the Bitcoin blockchain. The key difference from custodial wrapped coins like WBTC is that no single company holds the underlying Bitcoin — custody is spread across a rotating, decentralized group of signers.
How does tBTC work under the hood?
tBTC doesn't have its own blockchain or consensus — it's a set of Ethereum smart contracts combined with the Threshold Network's staking layer. When you deposit BTC, a randomly selected group of signers takes custody of it and locks collateral in Threshold's native T token, while the contract mints tBTC to you. If signers misbehave, their collateral is slashed and used to make depositors whole.
How is tBTC issued, and is there a fixed supply?
New tBTC is minted only when someone locks an equivalent amount of Bitcoin in the protocol, and it's burned when that Bitcoin is redeemed. There is no independent emission schedule or inflation — the supply simply mirrors the amount of BTC locked, growing and shrinking with demand.
How can I store and use tBTC?
Since tBTC is a standard ERC-20 token, any Ethereum-compatible wallet — MetaMask, Rabby, Ledger, and the like — works for storing it. On Ethereum you can lend it, provide liquidity, or use it as collateral in DeFi, and at any point you can redeem it back for native BTC through the Threshold protocol.
