Swap BTC to B 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 B 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 BUILDon you will receive on the BNB Smart Chain network at the current floating rate, with the payout network fee already taken into account.
Paste your B (BNB Smart Chain) 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 B is sent to your wallet. The order page shows every stage.
Swapping Bitcoin (BTC) for BUILDon (B) 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 B 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 BNB Smart Chain, so check that your BUILDon address belongs to that network before you confirm.
