1:1 Bitcoin-Peg

Burn tBTC on any deployment chain, receive native BTC to a Bitcoin address you control. 1:1, direct, and independent of the chain where the tBTC was issued.

Trust-Minimized by Design

Bitcoin custody is held by an honest majority threshold signer set that rotates on a fixed cadence. No single entity can move the underlying asset alone.

Zero-loss Technology

Six years on mainnet, $5.2B in cumulative bridge volume, zero loss-of-funds incidents. Audited by Least Authority, Trailbits, Mixbytes, ChainSecurity, and Certik, with a bug bounty on Immunefi.

FAQs

How do I mint tBTC?

Connect a self-custodied Bitcoin wallet, generate a one-time deposit address on app.threshold.network, and send at least 0.01 BTC to that address. tBTC is minted to the destination chain you selected, typically in one to two hours depending on Bitcoin confirmations.

How do I redeem my BTC?

Burn tBTC on the chain where it was issued via the Threshold app, specify a Bitcoin address you control, and the signer set releases the equivalent amount of native BTC 1:1. Redemption is permissionless and does not require an authorized merchant, account, or KYC.

Which networks support tBTC?

tBTC is live on Ethereum, Arbitrum, Base, Starknet, and Sui, with direct minting from Bitcoin to any of those chains. All deployments carry the same custody model and the same 1:1 redemption path.

What is the tBTC mint and redemption fee?

The tBTC mint and redemption fee is 0.2% (20 basis points). Fees can be partially or fully offset by staking the T token, and waivers apply automatically through the Threshold Unified Bitcoin Router.

Who manages tBTC?

Threshold Network (https://www.threshold.network) is the protocol behind tBTC. In February 2025, the DAO appointed Threshold Labs (tLabs) to manage the protocol’s operations, development, and growth.
