No account, no deposit, and no custody anywhere in the path.

How the BTC to CBTC swap works

Step 01

Enter your BTC amount

Open the pair with both sides preselected and type the amount of Bitcoin you are converting. The quote for CBTC updates with it, all-in, before anything is committed.

Step 02

Compare the live offers

The instant-exchange network returns competing offers for the pair and the best net CBTC amount is shown. The number you approve is the number that executes; there is no spread behind it.

Step 03

Confirm once

Approve the quote and send your BTC to the displayed address. One confirmation on the way in is all the flow asks; nothing is custodial anywhere in the path.

Step 04

Receive CBTC at your address

The CBTC settles on-chain to the address you chose, under Follows Base (~2 second blocks). From confirmation it is an ordinary balance: spend it, hold it, or route it on.

This pair crosses networks: the BTC leaves on Bitcoin (UTXO) and the CBTC arrives on EVM. The instant-exchange network handles both legs as one quoted trade, so the crossing is priced into the offer you approve rather than added after the fact.

Fees and settlement

Count it on one hand: 0.50% flat to the platform, stated in the quote with nothing behind it, plus each chain's gas for its leg of the trip. The route runs non-custodial end to end, so when the CBTC settles Follows Base (~2 second blocks) at your address, it is yours in the fullest sense: no custodian, no withdrawal queue, no platform in the path.
