XLM to TFUEL: Swap Stellar Lumens to Theta Fuel, No KYC

Theta Network runs on two native coins. THETA is the one staked in validator and guardian nodes and used for governance. TFUEL is the working coin: it pays the fee for every transaction on the chain, including moving THETA itself. A Theta Wallet that holds THETA and no TFUEL is stuck until some TFUEL arrives.

That is the most common reason for this direction. Someone keeps spare value in XLM, which moves cheaply on Stellar, and needs fuel on the Theta side. Others want TFUEL to work with Theta smart contracts or video relaying, or simply want a stake in Theta without opening an exchange account.

The two chains share nothing. Stellar is a payments ledger with G addresses and memos; Theta uses 0x accounts. This swap takes XLM on Stellar and pays TFUEL on Theta mainnet, with no bridge and no wrapped token. The rate comes from aggregated liquidity from leading crypto markets and floats until your XLM deposit confirms, and the box shows the TFUEL amount after fees before you send.

Your sender address is the Stellar account you pay from. It is a 56-character string beginning with G. Lobstr and Freighter both show it on their receive page. Use a wallet whose keys you hold, because a refund goes back to this exact address.

Every Stellar account must keep a small XLM reserve that cannot be spent, plus a little more for the fee. If you try to send your whole balance, the wallet will refuse. Enter an amount a bit below the full balance instead.

The Memo needs care. If the deposit page shows a Memo, copy it into the memo field of Lobstr or Freighter exactly as shown. If no Memo is shown, leave that field empty. Do not invent one or reuse a memo from an earlier transfer.

Stellar settles in a few seconds, so the deposit is seen almost as soon as you press send. You can follow it on StellarExpert by pasting your G address.

TFUEL is paid to a Theta Network address. It starts with 0x followed by 40 hexadecimal characters, the same shape as an Ethereum address. That likeness is where people slip. Take the address from a wallet that supports Theta Network, such as Theta Wallet, so you can see and move the coins once they land.

The same 0x address holds both THETA and TFUEL. If you already own THETA, paste that address and the fuel lands next to it, ready to pay for moving or staking the THETA.

A Stellar G address does not belong in the payout field, and neither does an exchange deposit address you copied months ago. Copy the 0x address fresh from the wallet, paste it, and compare the first and last characters before you confirm. Theta Network confirms the payout in a few minutes, and Theta Explorer shows the incoming TFUEL by address.

Unlike a token, TFUEL needs no second coin to move. It is the gas coin on Theta, so a wallet that holds only the TFUEL from this swap can send it straight away. Keep a small amount aside whenever you move the whole balance, so the next transaction on that address still has fuel.

If your aim was to stake or move THETA, the TFUEL now covers those fees. If you wanted THETA as well, the separate XLM to THETA page pays the other Theta coin to the same kind of address, and THETA to TFUEL covers a THETA holder who needs fuel without leaving Theta.

Searching for a TFUEL price or a TFUEL to USD figure is common before a swap like this. The exchange box is the practical answer here: it turns your XLM amount into the TFUEL you receive, with fees already taken out, and the figure updates with the market.

Nothing in one column works in the other. A Stellar wallet cannot hold TFUEL, and Theta Wallet has no G address, so you need both apps open while you set up the swap: one to send, one to copy the payout address. The Memo row is the only extra step, and it applies to the Stellar side alone. On the Theta side the receiving coin is also the fee coin, which keeps life after the payout simple: there is no second balance to top up.

If a swap cannot be completed, the coins are refunded to the sender address you entered. On this page that is your Stellar G address, which is why it should be your own Lobstr or Freighter account and not a shared exchange account that needs its own memo to credit you.

The status page tracks each step with a swap ID. If StellarExpert shows your payment as successful but the status has not moved for a long time, write to support@ghostswap.io with the swap ID and the Stellar transaction hash. The same applies if you sent without a Memo that the deposit page asked for: say so in the message instead of sending a second payment.

Most problems on this pair start with three things: a missing Memo, a payout address from a wallet without Theta support, or an amount that differs from the one entered in the box. Checking those before you press send avoids nearly all of them.
