Swap CHECK to BTC in three steps without creating an account. You see an estimated amount before you send, the exchange runs automatically once your deposit confirms, and the BTC goes straight to the wallet address you enter.
Enter the amount of Checkmate you want to swap in the widget above. It shows an estimate of the Bitcoin you will receive on the Bitcoin network at the current floating rate, with the payout network fee already taken into account.
Paste your BTC wallet address and check it twice, because blockchain transfers cannot be reversed. If the coin needs a memo or destination tag, a field for it appears. xswap.to never asks for your private keys.
Confirm the order and send your CHECK to the one-time deposit address on the Base network. Once the deposit confirms, the swap runs automatically and the BTC is sent to your wallet. The order page shows every stage.
Swapping Checkmate (CHECK) for Bitcoin (BTC) here takes one transfer from your wallet: no exchange account, no balance to deposit and no withdrawal queue. You choose the receiving address, and the BTC goes there once the swap completes.
Rates are floating, so the amount shown is an estimate that can shift slightly while your Checkmate deposit confirms on Base. The payout is sent on Bitcoin, so check that your Bitcoin address belongs to that network before you confirm.
Refreshed hourly. The widget shows the live estimate.
80 CHECK
≈
--- BTC
At the latest hourly update, 80 CHECK converts to about --- BTC. The figure comes from the floating rate and already allows for the payout network fee. Rates move, so the widget recalculates the estimate when you enter your own amount, and no account or registration is needed to swap.
