On-chain gold guide

How to hold gold on-chain (XAUT) in 2026

A gold token is a claim on one ounce of vaulted gold that you can keep in your own wallet and sell at any hour. This guide covers what backs the two tokens that matter, XAUT and PAXG, how they compare with a gold ETF, and how to buy and keep one without a brokerage account.

What on-chain gold is

On-chain gold is a token on a blockchain that represents a fixed amount of physical gold, almost always one fine troy ounce. The issuer buys the gold, stores it with a vault, and creates tokens against it. You can hold the token in a wallet, send it to anyone, and sell it at any hour, in fractions as small as you like.

Two products hold almost the whole market: XAUT (Tether Gold), worth $3.38 billion on 10 October 2026, and PAXG (Pax Gold), worth $1.84 billion. Other gold tokens are small or thinly traded. For a shorter primer, see what tokenized gold is and who it's for.

What backs it

  • Allocated bars. Each token is a claim on one ounce on specific London Good Delivery bars, not on a pool. Both issuers let holders look up the bars behind their tokens.
  • XAUT: issued by TG Commodities Limited (Tether group, British Virgin Islands), gold in Swiss vaults. Tether's attestation for 30 June 2026 shows 707,747 ounces held against 707,747 tokens issued.
  • PAXG: issued by Paxos Trust Company, regulated by New York's Department of Financial Services, gold at Brink's in London, with monthly attestations.
  • Contract: the original XAUT is on Ethereum at 0x68749665FF8D2d112Fa859AA293F07A622782F38. Copycat tokens with the same name exist, so add it by address.

Attestations confirm holdings on one date; they are narrower than an audit. The evidence for XAUT is set out in the Tether Gold review, and the issuer-by-issuer differences in PAXG vs XAUT.

A tokenized ETF share such as GLDx is a different thing: a token of a fund share rather than a claim on a bar. The fund's yearly fee comes out underneath the token, so each share slowly represents less gold. The arithmetic is in the GLDx guide.

On-chain vs physical vs ETF

With gold at about $4,038/oz, the three ways to own it trade one cost for another:

  • Coins and bars: you hold the metal and depend on no issuer, but pay a dealer premium of a few percent, and storage and insurance if you don't keep it at home.
  • Gold ETF: simplest for someone with a brokerage account. You pay a yearly fee (GLD 0.40%, IAU 0.25%) and trade in market hours.
  • Gold token: no storage fee and no market hours, but you rely on the issuer, its contract and your own wallet.

The full comparison is on physical gold vs ETF vs tokenized gold.

XAUT vs PAXG vs gold ETF

Once you have decided on a token, the choice is between XAUT and PAXG. A gold ETF is the brokerage baseline.

Dimension XAUT (Tether Gold) PAXG (Pax Gold) Gold ETF
One unit Claim on 1 oz on an allocated London Good Delivery bar Claim on 1 oz on an allocated London Good Delivery bar Share in a trust that holds bullion
Issuer TG Commodities (Tether group), British Virgin Islands Paxos Trust Company, regulated in New York Fund sponsor, under securities law
Vault Switzerland Brink's, London Fund custodian bank
Reserve reports Quarterly attestation Monthly attestation Audited fund accounts
Market value, 10 Oct 2026 $3.38 billion $1.84 billion GLD alone is far larger
Yearly holding fee None None GLD 0.40%, IAU 0.25%
Typical gap to spot −0.03% (daily median since 24 Sep 2026) +0.10% (daily median since 24 Sep 2026) Tracks net asset value
Trading hours Any time Any time Market hours
Needs a brokerage account No No Yes
Metal delivery Whole bars (~430 oz), Switzerland, 0.25% fee Whole bars (~430 oz) Not for retail holders

PAXG has the stronger regulator and more frequent reports. XAUT is larger and has the deeper market. Both track spot closely: the daily record is on the XAUT and PAXG premium history page.

Who on-chain gold suits

It suits people who already hold crypto or stablecoins and want part of it in gold without opening a brokerage account or moving money through a bank. For them, USDT to gold is one swap, and the gold stays where the rest of their money already is, sellable on a Sunday night.

It does not suit someone who wants metal in hand, wants to redeem small amounts for coins, or keeps all their savings at a broker, where an ETF is simpler. The full list is in who should not buy tokenized gold.

Buying gold with USDT

There are three routes, and all of them start from USDT:

  1. A centralized exchange with an XAUT/USDT or PAXG/USDT pair. Simple and cheap on fees, but the exchange holds the token until you withdraw it.
  2. A DEX swap on Ethereum, from your own wallet. You hold the token from the first second, but pay gas and must check the contract address yourself.
  3. A wallet's built-in swap, which routes the trade for you. Check the quoted rate against spot before you confirm.

On Ethereum, gas is a fixed cost per transaction: $5 is 0.05% of a $10,000 order and 10% of a $50 one. Price the whole route before you buy. Buying directly from Tether is possible only from 50 XAUT, with a 0.25% fee. Step-by-step instructions are in how to buy XAUT with USDT.

Holding it yourself

  1. Back up the wallet first. Write the recovery phrase down and keep it offline. Nobody can restore it for you.
  2. Add the token by contract address, not by searching the ticker.
  3. Keep some ETH in the wallet. Every transfer pays gas in ETH, so a wallet holding only XAUT cannot move it.
  4. Send a small test amount before moving a large balance in or out.

Self-custody vs a bank vault

These are not two versions of the same thing. A bank safe deposit box holds metal you own, and in most countries its contents are not covered by deposit insurance; you reach it in person, in branch hours. A self-custodied token is a claim on an issuer that you control with a key, reachable at any hour, and worth what the issuer can honour.

Bank safe deposit boxOn-chain, self-custodied
What you holdThe metal itselfA claim on metal held by an issuer
Who can block accessThe bank, a court, or a branch closureNobody holds your key, but the issuer can freeze the token
When you can reach itBranch hours, in personAny time, from anywhere
If you lose accessThe box is drilled after you prove your identityNo recovery: if the key and its backup are gone, so is the balance
Who you rely onThe bank's premises and proceduresThe issuer's solvency, vault and legal structure
Splitting and sendingPhysical, in personAny fraction, in one transaction

A box removes issuer risk; a token removes anyone else's hand from your balance but keeps the issuer. Allocated storage through a bullion dealer sits between them: metal rather than a claim, reached through a provider in business hours. The full storage comparison is in self-custody gold vs bank vault storage.

Moving it between wallets

A transfer is an ordinary token transaction, and the usual mistakes are final.

  1. Use the same network on both sides. Sending to an address on the wrong network is the most common way tokens are lost.
  2. Check the receiving wallet shows the official contract, not just the ticker. XAUt0 on another chain is a different token from XAUT on Ethereum.
  3. Send a test amount and wait for it to arrive.
  4. Keep ETH for gas in the sending wallet.

Moving between chains is a separate operation. A bridge adds its own contract and operator, so treat it as a new decision, not a longer transfer.

Risks

  • Issuer: you rely on TG Commodities or Paxos to hold the gold and honour the claim. A regulator can also act on an issuer: in 2023 New York ordered Paxos to stop issuing its BUSD stablecoin.
  • Contract: both issuers can freeze addresses. XAUT's contract can be upgraded by a Tether multisig without a timelock.
  • Price gap: you sell at the market price, not the gold price. On 25 September 2026 XAUT traded 1.05% and PAXG 1.08% below spot in StackFi's snapshots.
  • Redemption: metal is delivered only in whole bars of about 430 ounces. Everyone else exits by selling.
  • Wallet: a lost recovery phrase or a wrong-network transfer cannot be undone.

Each one is set out with its evidence in tokenized gold risks.

Frequently asked questions

Is tokenized gold like XAUT actually backed by real gold?

By the issuers’ reports, yes. Each XAUT and each PAXG is a claim on one fine troy ounce on allocated London Good Delivery bars. At 30 June 2026 Tether reported 707,747 ounces in Swiss vaults against 707,747 XAUT issued. Paxos reports PAXG reserves monthly. Both reports are attestations on one date, not continuous audits.

Who issues XAUT and where is the gold stored?

TG Commodities Limited, a British Virgin Islands company in the Tether group. The gold is held in vaults in Switzerland. PAXG is issued by Paxos Trust Company, regulated in New York, with the gold at Brink’s in London.

What blockchains does XAUT run on?

The original XAUT is on Ethereum at 0x68749665FF8D2d112Fa859AA293F07A622782F38, which has the most liquidity. Tether lists any other supported networks on gold.tether.to. XAUt0, a bridged version used on some other chains, is a separate token with an extra bridge layer.

Do I really own the gold, or just an IOU?

You own a claim on gold held by the issuer, not the bar itself. Holding the token in your own wallet removes the exchange from the chain, but the issuer, its contract and its vault remain. You can turn the claim into metal only in whole bars of about 430 ounces.

How is holding gold on-chain different from a gold ETF?

An ETF is a share in a fund, held at a broker, traded in market hours and charged a yearly fee (GLD 0.40%, IAU 0.25%). A gold token is held in a wallet, can be sent or sold at any hour, and has no storage fee from the issuer. The ETF has fund and broker risk; the token has issuer, contract and wallet risk.

Which is better, PAXG or XAUT?

Neither for everyone. PAXG has a New York regulator and monthly reserve reports. XAUT is larger ($3.38 billion against $1.84 billion on 10 October 2026) and reports quarterly. Choose the issuer you would rather trust.

What's the best way to hold gold on-chain in self-custody?

In a wallet whose recovery phrase you have written down and stored offline, on Ethereum, with a little ETH for gas. Add the token by its official contract address, not by searching the ticker, and send a small test amount before moving the rest.

How do I buy XAUT, and can I buy gold with USDT?

Yes. USDT to XAUT is the most common route: on an exchange with an XAUT/USDT pair, in a DEX swap on Ethereum, or in a wallet’s built-in swap. Check the contract address and the total cost, including gas, before you confirm. On Ethereum, gas is a fixed cost, so it weighs most on small orders.

Self-custody gold or a bank vault — which is better?

They protect you from different things. A safe deposit box holds the metal itself and removes issuer risk, but you can reach it only in branch hours and its contents are usually not covered by deposit insurance. A self-custodied token is reachable at any hour and nobody else holds the key, but it is a claim, so you carry the issuer’s risk, and a lost key with no backup cannot be recovered.

How do I move tokenized gold between wallets?

It is an ordinary token transfer. Check that both wallets use the same network, add the token by its official contract, send a test amount first, and keep some ETH in the sending wallet for gas. A transfer to the wrong address or network is usually lost for good.

Is it safe to hold gold on-chain?

It is as safe as its weakest layer: the issuer, the reserve evidence, the token contract, the market you sell in and your wallet. Both issuers can freeze addresses. On 25 September 2026 both tokens briefly traded about 1% below spot. None of this changes gold’s own price risk.
