To swap XAUT to USDT, choose XAUT on Ethereum as “from” and USDT on the network you want as “to”, approve XAUT once and confirm. On November 12, 2026, $1,000 of XAUT (0.254569 XAUT) quoted 997.26 USDT on Ethereum, about 3,917 USDT per ounce, in a single block, before the 0.7% service fee. If you want USDT on BNB Chain, Solana or Tron, one cross-chain route converts and moves it.
Key Takeaways
- Route type: DEX aggregators on Ethereum (5-6 routes on our check), or one-step cross-chain.
- Time: one Ethereum block on the same network; 1 second to Solana, 17 seconds to BNB Chain, about 102 seconds to Tron.
- Cost: a flat 0.25% route fee plus $0.05-0.47 of Ethereum gas on our check.
- Main catch: USDT does not follow gold; once you swap, a gold rally no longer helps you.
What Is XAUT?
XAUT (Tether Gold) is a token issued by Tether in which each unit represents one troy ounce of physical gold on a London Good Delivery bar stored in Switzerland. It is an ERC-20 token on Ethereum (contract 0x6874...2F38, 6 decimals). CoinGecko counted about 809,000 XAUT in circulation on November 12, 2026, a market cap of about $3.17 billion, and priced it at $3,921.70; LI.FI’s reference price was $3,928.21.
What Is USDT?
USDT is Tether’s dollar stablecoin, the most used stablecoin on exchanges and on Tron. It exists as separate tokens on Ethereum, Tron, BNB Chain, Solana and other networks, each with its own gas coin: USDT networks explained.
How the XAUT to USDT Swap Works
On Ethereum, aggregators (Fly, Nordstern, SushiSwap, OKX DEX, 1inch, Kyberswap) route XAUT through on-chain pools to USDT; you approve XAUT once and sign the swap. For USDT on another network, a bridge or solver (Layerswap, NEAR Intents, Relay and others) takes your XAUT on Ethereum and pays USDT on the destination, so you sign only once.
Quotes by Amount (Ethereum, November 12, 2026)
| You send | XAUT | You receive | Route fee | Gas | Best route |
|---|---|---|---|---|---|
| $100 of XAUT | 0.025457 | 99.67 USDT | $0.25 | $0.05 | SushiSwap |
| $1,000 of XAUT | 0.254569 | 997.26 USDT | $2.50 | $0.30 | Fly |
| $10,000 of XAUT | 2.545689 | 9,966.87 USDT | $25.00 | $0.47 | Nordstern |
The rate held at about 3,915-3,917 USDT per XAUT from $100 to $10,000, so pool depth absorbed $10,000 without visible price impact. Quotes are LI.FI routes before the 0.7% Step Exchange service fee; gold and the quote move every minute.
Which Network to Receive USDT On ($1,000 of XAUT)
| USDT on | You receive | Route | Time | Gas you need later |
|---|---|---|---|---|
| Ethereum | 997.26 USDT | Fly | one block | ETH |
| BNB Chain | 997.48 USDT | Layerswap | about 17 s | BNB |
| Solana | 994.65 USDT | Relay | about 1 s | SOL |
| Tron | 993.07 USDT | NEAR Intents | about 102 s | TRX |
BNB Chain paid slightly more than staying on Ethereum on this check. Tron paid the least, 4.41 USDT below BNB Chain, and moving USDT on Tron later needs TRX for energy; see USDT to TRX.
XAUT vs PAXG
Both tokens represent one troy ounce of gold, but different issuers stand behind them: Tether for XAUT, Paxos, a New York-regulated trust company, for PAXG. On November 12, 2026, $1,000 of XAUT quoted 997.26 USDT and $1,000 of PAXG 995.30 USDT on Ethereum, a 0.2% gap. XAUT’s supply was about 1.8 times PAXG’s. Selling PAXG instead: PAXG to USDT.
Swap or Redeem With Tether?
Tether offers redemption of XAUT for physical gold delivered in Switzerland or for its value, through a verified Tether account and subject to its terms and minimums. That route suits large holders who want the metal itself. For selling a few ounces or less into dollars, an on-chain swap is faster, needs no account and settles in seconds.
Step by Step
- Connect your Ethereum wallet holding XAUT, with a little ETH for gas.
- From: XAUT on Ethereum. To: USDT on Ethereum or another network.
- Approve XAUT once, keep slippage at 0.3-0.5%.
- Paste the receiving address if USDT goes to another network (T… for Tron, base58 for Solana).
- Check USDT received and confirm.
Mistakes to Avoid
- Forgetting decimals: XAUT has 6 decimals and 1 XAUT is a full ounce; 0.25 XAUT is about $1,000.
- No ETH for gas: the swap starts on Ethereum.
- Sending USDT to the wrong network: match the exchange deposit network (TRC-20, BEP-20, ERC-20, SPL).
Other stablecoin routes: USDT to USDC, ETH to USDT, BTC to USDT.
