Swap BTC to API3 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 API3 goes straight to the wallet address you enter.
Enter the amount of Bitcoin you want to swap in the widget above. It shows an estimate of the api3 you will receive on the Ethereum network at the current floating rate, with the payout network fee already taken into account.
Paste your API3 (Ethereum) 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 BTC to the one-time deposit address on the Bitcoin network. Once the deposit confirms, the swap runs automatically and the API3 is sent to your wallet. The order page shows every stage.
Swapping Bitcoin (BTC) for api3 (API3) 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 API3 goes there once the swap completes.
Rates are floating, so the amount shown is an estimate that can shift slightly while your Bitcoin deposit confirms on Bitcoin. The payout is sent on Ethereum, so check that your api3 address belongs to that network before you confirm.
Refreshed hourly. The widget shows the live estimate.

≈
--- API3
At the latest hourly update, 1 BTC converts to about --- API3. 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.
