What Is a Gold-Backed Cryptocurrency?

A gold-backed cryptocurrency is a blockchain token whose issuer claims that each unit is redeemable for, or fully collateralized by, a specific amount of physical gold held in a vault. The token itself lives on a public blockchain (usually Ethereum), but the value reference sits in a safe deposit room in London, Switzerland, or Singapore.

The category is often described as a “gold stablecoin” because the price tracks gold rather than the US dollar. The economics differ sharply from USD stablecoins. Gold itself moves, so a PAXG holder is long gold, not long dollars in token form. The stability refers to the token’s relationship to an ounce of metal, not to fiat purchasing power.

As of early 2026, the combined market capitalization of gold-backed tokens sits at roughly $1.5 to $2 billion, a fraction of the $90+ billion held in gold ETFs and an even smaller fraction of the roughly $15 trillion global physical gold market. The category is real but niche.

Why the Category Exists

Three practical reasons drive demand for gold tokens. First, 24/7 trading. Gold futures and ETFs stop trading on weekends. PAXG and XAUT do not. For traders in Asia dealing with US market hours or for holders who want to rotate into or out of gold during geopolitical weekend events, tokenized gold removes the trading calendar.

Second, divisibility. PAXG is divisible to 18 decimal places. A holder can own a millionth of an ounce. Physical gold has a practical minimum at the gram bar level; ETFs trade in whole shares. Tokenized gold removes granularity friction, which matters for programmatic treasury management and DeFi collateralization.

Third, composability. A PAXG balance can serve as collateral inside lending protocols, be paired in automated market makers, or move cross-chain through bridges. None of that is possible with an ETF share or a gold bar in a vault.

What Are the Major Gold-Backed Tokens?

Four tokens account for the overwhelming majority of the gold-backed crypto market. Each has a different custody model, issuer, and audit approach.

PAX Gold (PAXG)

PAXG is issued by Paxos Trust Company, a New York-regulated trust company overseen by the New York Department of Financial Services (NYDFS). Each PAXG token represents one troy ounce of a London Good Delivery gold bar held in Brink’s London vaults. Good Delivery bars are 400 oz LBMA-accredited bars, the reserve-grade standard used by central banks and the LBMA clearing system.

Supply sits at roughly 260,000 to 290,000 ounces depending on redemption activity. Paxos publishes the serial number of each allocated bar; holders with sufficient balance can look up their specific bars on the Paxos website. Monthly attestations from Withum (an independent accounting firm) verify the reserve backing.

Redemption is available in three forms. Holders of 430+ PAXG can redeem for an unallocated London Good Delivery bar, with the holder coordinating delivery or sale through LBMA channels. Smaller holders can redeem for fractional gold through a partner dealer network. Fiat redemption at USD spot is available via Paxos-linked exchanges.

Tether Gold (XAUT)

XAUT is issued by TG Commodities Limited, a Tether affiliate. Like PAXG, each token represents one troy ounce of a London Good Delivery bar, with vault locations in Switzerland. Supply sits around 250,000 ounces in early 2026.

The custody model is functionally similar to PAXG, but the regulatory and disclosure posture differs. Tether’s reserves have been the subject of repeated regulatory scrutiny, and XAUT’s attestation practices are less rigorous than Paxos’. For many institutional users, this disclosure gap is the deciding factor between the two tokens. Retail holders often prefer XAUT for its availability on exchanges like Bitfinex and for slightly tighter spreads in certain pairs.

Redemption requires a minimum of 430 XAUT (the size of a Good Delivery bar, roughly). Smaller holders must sell on exchanges rather than redeem directly.

CACHE Gold (CGT) and DGLD

CACHE Gold uses a different custody design. Each CGT token represents one gram of gold (not one ounce), held across a distributed network of vaults with individual bar-level verification. DGLD, originally launched on the Blockstream Liquid sidechain, uses a similar allocated model with Swiss vaulting.

Both tokens have struggled with liquidity. Combined supply is modest, and bid-ask spreads on centralized exchanges are wider than PAXG or XAUT. The technical design is sound, but network effects have concentrated liquidity in the two market leaders.

GLDT and Newer Entrants

GLDT launched on the Internet Computer in 2024 as a token backed by allocated gold held with Swiss partners. Several bank-issued tokens have appeared on permissioned chains, including HSBC’s tokenized gold pilot and a Commerzbank project. These institutional tokens rarely reach public markets but indicate growing interest in the rail itself.

How Does Redemption Actually Work?

Redemption is the feature that separates genuine gold tokens from unbacked synthetic claims. The process differs by issuer but follows a common pattern.

For PAXG, a holder with 430+ tokens (the rough size of a Good Delivery bar) can initiate redemption through the Paxos platform. The holder provides KYC documentation, selects a delivery method (allocated bar pickup at the vault, delivery through an LBMA member dealer, or fiat settlement), and pays a redemption fee. The timeline is typically 2 to 5 business days for fiat, longer for physical delivery.

Below the 430-ounce threshold, redemption is possible only through partner dealers who break down bars into smaller units. This introduces dealer premiums and spreads; the economics of small redemptions rarely make sense versus simply selling on exchange.

The practical takeaway: redemption exists and is real, but it is designed for institutional and high-net-worth holders. A retail investor with 10 PAXG is effectively locked into selling on a secondary market rather than taking physical delivery.

What Are the Tax Implications?

US tax treatment of gold-backed tokens sits at an unresolved intersection between cryptocurrency and collectibles rules. The IRS has not issued specific guidance.

The conservative interpretation applies both frameworks. A sale of PAXG for USD is a taxable disposition of a digital asset, subject to capital gains tax. Because the underlying asset is gold, the 28% collectibles rate may apply to long-term gains rather than the standard 20% rate. Some tax professionals argue that the token’s digital-asset status overrides the collectibles classification; others argue the economic substance (ownership of gold) controls.

Swapping PAXG for another cryptocurrency is a taxable event under current US crypto tax rules, triggering gain or loss based on the USD value at the time of the swap. This is a significant friction versus physical gold, where a dealer-to-dealer exchange of bullion can sometimes qualify for simpler tax treatment, though the IRS has also narrowed like-kind exchange treatment for most metals since 2018.

For large holders, the conservative approach is to assume collectibles treatment applies on long-term gains and to document the acquisition cost (including any premium paid) carefully for basis tracking. Consult a tax professional; this is not an area where generic crypto tax software reliably handles the edge cases.

Pros and Cons of Gold Tokens

Advantages

24/7 liquidity. Weekend geopolitical events cause price gaps in gold futures when markets open Sunday evening. Tokenized gold reprices continuously across global exchanges. For active risk management, this matters.

Divisibility. Holding 0.003 ounces of gold is impossible physically and awkward via fractional shares. Tokens handle this natively. Useful for payroll, automated treasury allocations, or small recurring purchases.

No vault logistics. Storage, insurance, and authentication are handled by the issuer. A token balance appears in a standard crypto wallet.

Portability. Moving $10 million of PAXG between jurisdictions requires an Ethereum transaction. Moving $10 million of physical gold requires an armored transport, export documentation, and customs filings that can take weeks.

Composability. PAXG can be deposited in Aave as collateral, paired in Uniswap, or wrapped onto other chains. Physical gold cannot collateralize DeFi lending. For capital-efficient strategies, this is a meaningful edge.

Disadvantages

Counterparty risk. A PAXG holder depends on Paxos remaining solvent, honest, and operationally competent. An XAUT holder depends on Tether. Physical gold held at home has none of this exposure. Even a gold ETF sits inside a more heavily regulated and audited structure than most token issuers.

Smart contract risk. The ERC-20 contract governing PAXG could be exploited through a bug or a compromised admin key. This risk is small but nonzero and has no analog in ETFs or physical.

Platform dependency. Centralized exchanges delisting a token, regulatory actions against an issuer, or stablecoin-specific regulation could impair liquidity rapidly. The 2022 collapse of several centralized platforms (Celsius, BlockFi, FTX) showed how quickly crypto infrastructure can fail.

Regulatory ambiguity. Gold tokens sit in an unclear zone between commodities regulation (CFTC), securities regulation (SEC), banking regulation (NYDFS in the case of Paxos), and crypto-specific frameworks still being written. A change in any of these frames could force redemption, delisting, or restructuring.

Spreads and fees. PAXG and XAUT typically trade at a 0.2% to 1% premium to spot gold on major exchanges, with wider spreads during stress. Over multi-year holds, this can exceed the expense ratio on a low-cost ETF like GLDM (0.10% per year).

How Do Tokens Compare to Physical and ETFs?

Each vehicle solves a different problem.

Physical gold maximizes counterparty independence and provides the cleanest tax treatment (collectibles rate, no crypto disposition rules). It imposes storage and authentication friction and trades with 2 to 8% premiums depending on form.

Gold ETFs like GLD and GLDM offer the lowest all-in ongoing cost (0.10 to 0.40% expense ratio), deep liquidity in brokerage accounts, and clean collectibles tax treatment. They require a brokerage account, trade only during US market hours, and carry custodian counterparty risk. See our gold ETF guide for full comparisons.

Tokenized gold wins on 24/7 trading, divisibility, and composability. It introduces smart contract and issuer-specific risks that physical and ETFs do not carry, and tax treatment remains less clean.

A reasonable allocation framework: physical gold for the core long-term position, a gold ETF in retirement accounts for tax-advantaged growth, and tokenized gold for active traders or DeFi-specific use cases. Very few investors need all three.

Is PAXG Safer Than XAUT?

Both tokens are backed by London Good Delivery gold in accredited vaults. The difference lies in the regulatory framework surrounding the issuer.

Paxos operates under the New York DFS trust charter, which imposes capital requirements, segregated reserve rules, and regular examinations. Reserve attestations are published monthly. The trust structure means that if Paxos became insolvent, PAXG holders would have a priority claim on the gold reserves rather than being unsecured creditors.

Tether Gold operates under a different regulatory structure (offshore Tether affiliate), and Tether’s broader operation has faced enforcement actions from the CFTC and NY Attorney General over disclosure practices in its USDT product. These enforcement actions were not specific to XAUT, but the same management and reserve practices apply.

For institutional holders prioritizing disclosure and regulatory oversight, PAXG is the conservative choice. For retail traders prioritizing liquidity and exchange availability (particularly on Bitfinex), XAUT has operational advantages. For most buy-and-hold investors, the Paxos framework’s stronger disclosure regime is worth the slightly smaller exchange footprint.

Frequently Asked Questions

Is PAXG the same as owning physical gold?

Functionally close, but not identical. A PAXG token represents an allocated claim on a specific London Good Delivery bar held by Brink’s on behalf of Paxos. If Paxos remains solvent and operational, that claim is strong. However, a PAXG holder does not have direct physical possession. A disruption to Paxos, its vault partners, or the Ethereum network could impair access in ways that direct physical possession would not experience.

Can I redeem PAXG for actual gold?

Yes, with a minimum of 430 PAXG (approximately the size of a Good Delivery bar). Holders can redeem for an allocated bar, for fractional gold through partner dealers, or for fiat at spot. Below 430 PAXG, practical redemption requires selling on the secondary market or aggregating with other holders.

Are gold tokens taxed like gold or like crypto?

Both frameworks apply, and IRS guidance is incomplete. The conservative assumption is that long-term gains are taxed at the 28% collectibles rate (because the underlying asset is gold) while crypto-specific rules (no like-kind exchanges, taxable swaps) govern transaction mechanics. Consult a tax professional familiar with both frameworks.

What happens to PAXG if Paxos goes bankrupt?

Paxos operates as a NYDFS-regulated trust company. Reserve gold is held in segregated accounts with Brink’s and is not part of Paxos’ operating balance sheet. In a bankruptcy scenario, PAXG holders would have a priority claim on those reserves rather than becoming unsecured creditors. The process of asserting that claim and recovering gold would still be slow and uncertain, but the structural protection is stronger than for most crypto custodians.

Can I use PAXG as collateral for loans?

Yes. Aave, MakerDAO, and several other DeFi protocols accept PAXG as collateral. Loan-to-value ratios are typically 50 to 65%, lower than stablecoin collateral because of gold’s price volatility. This composability is one of the main reasons institutional DeFi users hold tokenized gold rather than physical gold or ETFs.
