Swap cirBTC to BTC

Bitcoin at your own address. No custody, no sign-up.

Send cirBTC from Ethereum and receive bitcoin at an address you control, in a transaction anyone can verify. On-chain is the natural choice for larger amounts and for cold storage.

Your cirBTC is traded for tBTC on a decentralized exchange in the same transaction that locks it. The rate stays close to 1:1 and is shown on the card, together with the fees, before you commit.

The swap starts as soon as your cirBTC deposit is seen, and the payout confirms with the next Bitcoin blocks.

How it works

  1. 1Enter an amount and your Bitcoin address.
  2. 2Your cirBTC is converted to tBTC and locked in the swap contract on Ethereum.
  3. 3We lock the bitcoin in a matching contract.
  4. 4You claim it, which releases the tBTC to us.

Questions

Which address formats work?
Legacy, SegWit and Taproot addresses all work. You can also paste a BIP21 payment link or scan a QR code, and the amount comes across with it.
Who pays the Bitcoin network fee?
It is part of the quote. The fee breakdown on the card shows it before you commit.
What if the swap does not complete?
The swap is refunded on Ethereum. You get tBTC back, not cirBTC, because the conversion to tBTC happens before the funds are locked.
