🌕 Imagine 'gold' as a star, which has attracted global 'value' under the same gravitational rules for centuries. The so-called RWA (Real-World Assets on-chain) extends the gravity of this star to a programmable orbit on the chain. XAUT (Tether Gold) and PAXG (Pax Gold) are the two brightest 'on-chain golds', both following international gold prices, but their orbits and satellites (compliance, custody, fees, redemption) differ greatly. This article clarifies the seven major questions you care about the most.
🪙 What is XAUT?
It is tokenized gold issued by Tether's TG Commodities: each 1 XAUT corresponds to 1 troy ounce of physical gold that meets LBMA 'London Good Delivery' specifications, stored in Swiss vaults; holders have 'fractional ownership' rights tied to specific gold bars marked with serial numbers, purity, and weight, which can be queried on the official website. XAUT is currently natively issued on Ethereum (ERC-20) and TRON (TRC-20); starting in 2025, Tether announced the launch of a cross-chain (omnichain) version 'XAUt0' on TON to expand availability.
🛡️ Is XAUT safe?
Consider three mechanisms: the first is 'physical gold custody + verifiability' — the serial numbers of the gold bars corresponding to each holding address can be verified on Tether Gold's query page; the second is 'third-party attestation' — Tether will provide a special reserve report for XAUT starting in 2025, with reasonable assurance opinions (ISAE 3000) and quarterly disclosures from independent accountants; the third is 'total amount correspondence' — in Q2 2025, it disclosed that reserves of gold exceeded 7.66 tons while revealing circulation. These allow you to externally verify 'whether there is real gold' instead of just taking slogans at face value.
🏷️ Does XAUT count as RWA?
Yes — it tokenizes 'the ownership certificate of physical gold', granting 24/7 liquidity, programmable settlements, and cross-border transfers after being on-chain, falling under the 'commodities' branch of RWA.
💸 How does investing in XAUT differ from 'regularly buying gold'? Off-chain gold purchases (physical bars, ETFs, securitized notes) typically circulate within T+2 settlement and traditional custody systems; on-chain gold offers instant, divisible (down to 0.000001 oz), global 24/7 transfers, and XAUT does not charge annual 'custody fees' to holders, only charging 25 bps transaction fees for initial purchases/redemptions from the issuer (cross-exchange transfers only incur on-chain gas fees). But be aware: 'physical redemption' from the issuer of XAUT must be processed in 'full gold bar' units (Swiss vault delivery), which is not suitable for those who only wish to withdraw small amounts of gold.
⚖️ What are the essential differences between XAUT and PAXG?
PAXG is issued by the regulated Paxos Trust Company in the U.S., supervised by NYDFS and guaranteed monthly by an external firm (starting in 2025, by KPMG); it supports queries for specific gold bars assigned to holding addresses. In terms of physical redemption, redeeming PAXG for a full 'Good Delivery' gold bar requires at least about 430 PAXG, or it can be directly redeemed into USD from Paxos; at the token level, it is primarily on Ethereum (ERC-20). In contrast, XAUT is issued by TG Commodities (a Tether Group affiliate) under the Salvadoran regulatory framework, providing quarterly attestations, natively on ETH/TRON, and expanding multi-chain scenarios through XAUt0. Your trade-offs usually lie between 'compliance domain and attestation frequency (PAXG wins)' and 'multi-chain availability and ecosystem coverage (XAUT wins)'.
🧭 Why start allocating RWA (on-chain gold)?
For retail investors, small 'dollar-cost averaging (DCA)' purchases of PAXG or XAUT provide exposure similar to gold prices while retaining the flexibility of on-chain transfers and collateralization (e.g., some platforms accept PAXG as collateral for derivatives or loans); for large holders, the key lies in 'collateral efficiency and liquidation pathways': risks of gold-backed assets can be capitalized, increasing capital utilization, but conservative LTV and liquidity thresholds must be set to avoid triggering on-chain liquidations during gold price pullbacks.
🏪 Buying gold in the cryptocurrency realm vs. buying gold in the real world?
Buying gold bars off-chain is compliant and clear, with physical ownership, but transfer and custody costs are high, and settlements are slow; buying XAUT/PAXG on-chain allows near-instant settlements, global transfers, and programmable usage (for collateral, cross-chain settlements), but introduces counterparty risks from 'issuers/custodians' and jurisdiction risks (XAUT has Swiss custody + Salvadoran regulation, PAXG has U.S. trust structure + NYDFS). You should decide which one to mainly hold based on your location, tax, and compliance requirements.
🧪 Actionable availability: How to verify and calculate costs by yourself?
🔎 Download the latest reserve reports and attestations from the Tether Gold 'Reports' page, comparing circulation and number of gold bars; then use your holding address to look up the serial number, purity, and weight on the official website. On the cost side: the initial purchase/redemption of XAUT directly from the issuer incurs a 0.25% fee, with no annual fee, and follows the 'full gold bar' redemption rules.
🧾 When switching to PAXG, first check the latest monthly attestation on Paxos's 'Transparency' page, then use PAXG Lookup to see the gold bars corresponding to your address; if you want physical gold bars, you need approximately 430 PAXG (depending on bar weight), or you can directly exchange it for USD from Paxos.
🧩 How to choose: XAUT or PAXG?
If you prioritize 'U.S. regulation and high-frequency attestations', desire an official channel for 'USD cash redemption', and mainly operate within the Ethereum ecosystem, PAXG would suit you better; if you value 'multi-chain coverage (ETH/TRON/TON-omnichain) + ecosystem liquidity' and 'no annual fees for long-term holding', XAU₮ would be more flexible. However, neither provides a 'real-time small gold bar withdrawal' solution — physical redemptions are primarily for full gold bars; if you want to obtain small gold pieces, traditional gold merchants might be more suitable.
⚠️ Risk symmetry reminder: on-chain gold maximizes liquidity but also introduces new risks — smart contracts, cross-chain bridges (especially for XAUt0/DeFi applications), issuance and custody legal risks, and operational risks of exchanges and wallets. Strictly diversifying holding addresses, retaining cold wallets, controlling leverage and LTV, and treating redemption rules (full gold bars) as part of a dynamic liquidity threshold is a relatively prudent approach.
