About this pair

cbBTC wraps Bitcoin for the Base ecosystem, and this pair unwinds that wrap back to native BTC. U.CASH compares live offers across instant-exchange partners and shows the best BTC receive amount before you commit. Send cbBTC to the deposit address on Base, and native Bitcoin lands at the address you specify.

Before you start

Two things and the pair is ready. A wallet holding your CBTC, and the BTC address you want the output delivered to, raw string or web3 name where your wallet resolves one. The preview shows the whole trade before anything is signed: what leaves, what arrives, the fee, and the network costs. Keys never leave your side at any point in the flow.

How the CBTC to BTC swap works

Step 01

Enter your CBTC amount

Open the pair with both sides preselected and type the amount of Coinbase Wrapped BTC you are converting. The quote for BTC 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 BTC 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 CBTC 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 BTC at your address

The BTC settles on-chain to the address you chose, under 1 confirmation (fast), 3 (standard). From confirmation it is an ordinary balance: spend it, hold it, or route it on.

This pair crosses networks: the CBTC leaves on EVM and the BTC arrives on Bitcoin (UTXO). 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 BTC settles 1 confirmation (fast), 3 (standard) at your address, it is yours in the fullest sense: no custodian, no withdrawal queue, no platform in the path.

CBTC to BTC: FAQ

What is cbBTC?

Coinbase Wrapped BTC is an ERC-20 on Base backed 1:1 by Bitcoin held by Coinbase, with 8 decimals matching Bitcoin. It brings BTC liquidity into Base for trading and DeFi.

Is swapping cbBTC the same as redeeming it?

No. Redemption through the issuer is Coinbase's own process. The instant rail instead trades your cbBTC for native BTC at the live market rate, no issuer account required.

How long does a cbBTC to BTC exchange take?

Base confirms in about two seconds, so the trade waits mainly on the Bitcoin payout. Most exchanges complete within ten to thirty minutes.

How long does a CBTC to BTC swap take?

At the chains' pace. The exchange leg commits after the incoming transfer confirms and the BTC settles 1 confirmation (fast), 3 (standard); the preview states the expectation with the quote, and the status you watch is the same one the settlement acts on.

Is the CBTC to BTC swap non-custodial?

Yes. Your wallet signs every step and the BTC settles to the address you chose; U.CASH never holds either asset, and there is no platform wallet anywhere in the route.
