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

At the latest hourly update, 1 BTC converts to about 1264255.2877022 TFUEL. 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.

Pay with bitcoin from any BTC wallet and pick up Theta Fuel (TFUEL) on the Theta blockchain at your own Theta address. The form asks for no login or email. TFUEL is the coin that pays for transactions on Theta, so a common buyer already holds THETA, or wants to use a Theta app, and finds the wallet cannot move anything until it has some fuel.
Theta runs a two-token design. THETA is the staking and governance token, while TFUEL is the operational coin used for gas, smart contract calls and rewards to edge nodes that share bandwidth and computing power. TFUEL is native to Theta mainnet rather than an ERC-20, so coming from the Bitcoin network makes this a cross-chain swap. Theta addresses use the same 0x format as Ethereum, but your wallet must be on Theta to see the coins. Theta payouts carry no memo.
Ahead of sending, the widget puts a floating-rate estimate on the TFUEL due, with the exchange margin and Theta's payout fee taken out. Treat it as a close guide, since the amount can move slightly if the market shifts before your BTC confirms. The bitcoin deposit, at about one block every 10 minutes, decides most of the wait. Once the payout goes out, you can find it by searching your 0x address on the Theta explorer.

Both are native coins of the Theta blockchain, but they do different jobs. THETA is staked by validator and guardian nodes and carries governance weight. TFUEL pays transaction fees and smart contract costs and is earned by edge nodes, so it is the coin you spend when you use the network.
It can work, because Theta uses the same 0x address format and an EVM wallet controls the same address on Theta. You only see the TFUEL after adding the Theta mainnet network to that wallet. A wallet built for Theta is the simpler choice if you also plan to hold THETA.
No, TFUEL here is the native coin of Theta mainnet, not an ERC-20 on Ethereum. The payout is a Theta transaction, so an Ethereum block explorer will not show it. Search your address on the Theta explorer instead.
TFUEL payouts do not use a memo, tag or payment ID, so the form only asks for your address. That address has to belong to a wallet or account that accepts TFUEL on Theta mainnet. If an exchange account is the destination, confirm it lists TFUEL deposits on the Theta network.
The timing mostly depends on the Bitcoin deposit: Bitcoin produces a block roughly every 10 minutes on average, and a low fee rate can push your transaction back in the queue. Once the deposit confirms, the exchange and the Theta payout follow. The order page updates through each stage so you can see where things stand.
Write to @xswap_to on Telegram with the transaction ID shown on your order page. Before you write, check the address on the order against your wallet and make sure the wallet is viewing Theta mainnet. Problems are reviewed case by case, and transfers already on chain cannot be reversed.
