Tokenized Gold & DeFi: How to Earn Yield on Gold-Backed Tokens

SECTION 1-THE PROBLEM

Gold Has Always Had a Yield Problem!

Gold is meant to do nothing; there are no dividends or interest, and there is no cash flow. A physical bar sitting in a vault in Zurich today will be the exact same bar ten years from now (worth slightly more if the gold price has gone up) and will not be worth a cent more as a result of holding it. In most of modern finance, this was just considered part of the deal: gold is money-like in that it’s a store of value, but unlike other assets in a portfolio, it’s not a source of income.

Tokenization has the potential to change this equation. When a physical commodity like gold can be represented as a token on a blockchain (each token cryptographically backed by, and convertible to, a specific weight of physical metal), it obtains a trait that it previously lacked: programmability. Physical gold in a vault can be deployed in a lending protocol, placed in a liquidity pool with another token, used as collateral to borrow stablecoins, or funneled through an automated yield-farming operation. Physical gold stays in the vault, but a digital claim to it begins to work.

Key insight:  Tokenized gold separates two things that were always bundled together in physical gold: the value of the metal and the form in which that value is held. The form can now earn yield; the metal stays safe.

This brief explains analytically and clearly what these yield mechanisms are, how they function, how much they pay, and what the associated risks are. This brief's purpose is not to push toward the adoption of any particular protocol, but to empower informed investors with the language and understanding to analyze tokenized gold yield opportunities according to their own terms.

SECTION 2-FOUNDATION

What Is Tokenized Gold, Exactly?

Before it, GoldOn talked about the above question a lot. Tokenized gold refers to a specific technical structure. An issuer buys and stores physically audited vaults of gold, usually in an allocated (i.e., one-to-one backed; bars assigned unique serial numbers to specific token holders) form. For every gram or ounce of gold in custody, an equivalent number of tokens is minted on a public blockchain, most commonly Ethereum, but also on BNB Chain, Tron, and Polygon. These tokens are freely transferable, tradeable on an exchange, and key to this post, available to use in DeFi applications. The two largest gold-backed tokens by market cap in mid-2026 are PAX Gold (PAXG), a Paxos product backed one-to-one by allocated gold bars held in a Brink’s vault in London, and Tether Gold (XAUt), a Tether product.

A newer tranche of issuers, some targeting MENA markets, in gram denominations, is quickly building out the space. These sometimes offer faster redemptions and closer integration to the gold refineries themselves.

Gram vs. ounce denomination:  PAXG and XAUt are denominated per troy ounce (~31.1 grams). Newer platforms denominate per gram, lowering the barrier to fractional ownership and making small-scale DeFi positions more accessible.

From a DeFi protocol's perspective, a gold-backed token looks like any other ERC-20 asset:  it has an on-chain price (via Chainlink, or whatever other mechanism), it can be collateralized, lent against, provided to pools, etc. The actual off-chain gold custody process remains hidden from the protocol, which is technically nice but makes it the investor's responsibility to perform due diligence.

SECTION 3-THE YIELD LANDSCAPE

Five Ways Tokenized Gold Currently Generates Yield

However, not all yield strategies have similar risk-reward profiles, liquidity, or return potential. The following is a hierarchical breakdown of the current gold-backed token yield-generation mechanics.

1. AMM Liquidity Provision (PAXG/USDC, XAUt/DAI pools)

Automated Market Makers (AMMs)-platforms like Uniswap, Curve, and Balancer accept deposits from the user into a shared pool where they are made available by the protocol. LPs will receive a share of all trading fees paid out of the pool. Gold-backed tokens are usually offered in two-token pairs, with one asset being a stablecoin (USDC, DAI, or USDT) and the other being ETH. The income stream from fees is a function of the trading activity occurring through the pool; typically, higher-volume/higher-volatility pools will generate more fee income.

As an example of expected yield on a Curve PAXG/USDC pool, yields have typically run between 3-12% APY, but they vary greatly depending on market conditions, and it's possible that Uniswap V3 concentrated liquidity can amplify those numbers even higher (but requires management).

Impermanent loss caveat: The price of gold and the value of a stablecoin tend not to move in the same direction. If the price of gold spikes up considerably while a stablecoin doesn't move, you will end up with proportionally less gold and more stablecoins in your position than you began with.

The other warning about impermanent loss: The two tokens deposited move relative to each other, so your two-token deposit changes in value relative to the amount of each token it contains. If gold continues to rise in value, you'll have proportionately more stablecoin than gold compared to your original deposit. This so called 'impermanent loss' actually causes the yield to be even lower, but it will revert if gold goes back to the deposit price. (May not).

2. Lending Protocol Deposits (Aave, Compound)

It is possible to lend out Gold-backed tokens on lending protocols to receive yield, while others will provide collateral to borrow on stablecoins or any other tokens, like on Aave V3, where the PAXG token has been added as a valid collateral on the platform. Therefore, it is possible to lend on PAXG to receive supply APY or borrow it. Supply APYs on Gold-backed tokens on lending protocols are on average smaller than on AMM pools (1-6% range) as their utilization rate (proportion of total deposited collateral that is lent out) is smaller than for AMMs. However, the risk profile is very straightforward (no impermanent loss) and the strategy is passive only; the only smart contract risk exposure is the one for the lending protocol.

One evolving strategy is to borrow stablecoins on Gold-backed token collateral and lend those stablecoins into a yield-boosting, or other more lucrative, strategy to maximize the potential for profit while significantly raising liquidation risks.

3. Yield Aggregators (Yearn, Beefy, Convex)

Yield aggregators are meta-protocols. You deposit into an aggregator; it directs the funds to the most profitable available underlying strategy, automatically compounds yields, and takes a small performance fee. This means that if you own gold, you deposit PAXG or XAUt into a vault, and the aggregator chooses and rebalances the underlying strategies for you.

Yields on gold-related positions for aggregators have historically ranged from 4% to over 15% annualized, depending on conditions and the underlying strategies available. This adds layers of smart-contract risk to gold token exposure (aggregator-contract risk on top of underlying protocol-contract risk). While the best aggregators have smart contract audits, no smart contract risk is entirely removed.

Auto-compounding effect:  At 8% APY, manual annual compounding turns $10,000 into $10,800 after year one. Beefy's daily auto-compounding at the same rate yields approximately $10,832,  a small but growing difference over multi-year holding periods.

4. Protocol Staking and Gauge Voting

Additionally, some DeFi protocols issue governance tokens as incentives to LPs. LPs can lock governance tokens (such as the veToken model seen on Curve with veCRV), and then vote to direct boosted rewards to gold-stablecoin pools they've committed liquidity to. This effectively layers on a secondary stream of yield on top of trading fees: governance token emissions. The math involved here is more involved and returns more unpredictably, as governance token prices fluctuate and emissions can decrease over time as more people claim their portion of the pool. During major incentive drives, though, gauge-boosted pools have provided substantial added yield for advanced depositors. Standard gold token APY from gauge systems can be between 2-8%, before considering the yield from governance token emissions

5. Gold-Collateralized Lending (Borrower Side)

This method turns the model on its head: instead of placing gold to earn interest, the gold token holder places it as collateral, takes out a stablecoin loan based on an agreed loan-to-value (LTV) ratio, and uses this capital elsewhere to invest in stablecoin yield schemes, further gold accumulation, or other financial instruments.

It’s not the gold that generates yield; it is the capital it unlocks that generates it. Holders of $50,000 in PAXG at 70% LTV can borrow up to $35,000 in USDC. If this is placed into a stablecoin lending pool generating 5% APY, it brings in $1750 in interest over a year on capital that was backed by gold rather than actively generating interest itself. The primary risk associated with this model is liquidation. If the price of PAXG falls, the ratio of collateral to loan falls below the risk threshold of the protocol, and the position is automatically liquidated in order to repay the stablecoin loan.

SECTION 5-RISK ARCHITECTURE

What Can Go Wrong: A Layered Risk Framework

Yield strategies in the context of tokenized gold layer risk on top of each other. This architecture is the only analytical exercise that truly matters before committing capital. There are four levels of risk to assess:

• Custodian/Issuer Risk: The underlying gold is held by a custodian and carries risks such as issuer solvency, regulatory risk (where token custody rules are uncertain in jurisdictions), and, extremely rarely, the risk of audit falsification. The usual defense is to use an issuer with monthly, independently audited proof of reserves.
• Smart Contract Risk: DeFi relies on self-executing smart contracts on-chain. If the code contains a bug or exploit, the deposits within could be lost to exploitation (which has already cost the DeFi ecosystem billions since 2020). Defense: audited contracts, TVL history, bug bounty schemes, and protocol age.
• Oracle/Price Feed Risk: Gold-backed token prices are derived in real-time via oracle networks such as Chainlink. A manipulated or stale oracle price can result in under-collaterized positions leading to flash loans, liquidation exploits, and bad debt accruals.
• Liquidity Risk: DeFi liquidity is highly withdrawable. A large run of withdrawals from a liquidity pool during stressful market conditions may be insufficient to exit positions at expected prices. Increased usage in lending protocols can lead to withdrawal freezes.

Framework question:  Before entering any tokenized gold yield strategy, ask: if this protocol were exploited tomorrow, which of my assets would be lost? The answer to that question defines your real risk exposure not the APY number.

SECTION 6- REGULATORY & ETHICAL DIMENSIONS

Regulatory Status and Shariah Compliance

Tokenized gold sits in a unique position between commodity law, securities law, and the nascent area of digital asset regulation, which regulators are not yet fully accustomed to defining clearly. The VARA framework in the UAE created a licensing framework that covers the classification and tokenization of gold leaving, in that instance, a cleaner operating environment than the majority of jurisdictions. MiCA regulations in the EU are to come into full effect in December 2024 and have established that gold-backed tokens would fall under the classification of "asset-referenced tokens" and require adequate reserve and disclosure conditions.

A key non-negotiable for investors within Muslim-majority countries, which comprise a considerable and ever-increasing portion of the addressable market for tokenized gold, is Sharia compliance. Interest is prohibited in Islamic finance, and most common DeFi yield mechanisms involve interest-bearing models. While there is academic discourse surrounding whether AMM trading fees represent permissible profit sharing (mudarabah-like) and notriba, a number of Sharia boards have issued conditional approvals, whereas some have not certified at all.

A more niche trend within the DeFi space (mostly gram-denominated gold platforms designed from the ground up in Gulf countries) is the formation of yield mechanisms that follow AAOIFI standards rather than relying on an interest-bearing model, but by utilizing the revenue stream from trading fees. While these are far less developed at this time, they represent the direction of travel for the $3.9T Islamic finance market.

SECTION 7- PRACTICAL ENTRY

How to Actually Get Started: A Decision Framework

For an investor who understands traditional gold but is new to DeFi, the practical path breaks down into four steps:

• Step 1: Choose Your Token. Select a gold-backed token from an audited, regulated issuer. Verify proof-of-reserves documentation, understand the redemption process (how you convert tokens back to physical gold or fiat), and confirm the jurisdiction of custody.
• Step 2: Start with the Simplest Strategy. For a first position, a lending protocol deposit (Aave with PAXG) offers the simplest entry: deposit, earn supply yield, withdraw at any time. No impermanent loss, no active management required. Lower yield, but significantly lower complexity.
• Step 3: Size According to Experience. Size the position relative to your DeFi experience. Capital you cannot afford to lose to a smart-contract exploit should not be in DeFi; regardless of yield, tokenized gold does not change that fundamental rule.
• Step 4: Monitor and Rebalance. APYs in DeFi shift constantly. What yields 8% today may yield 2% in three months as capital flows in and utilization rates change. Set a calendar reminder to review positions quarterly and be willing to move capital as conditions change.

CONCLUSION

For most of financial history, the question of what to do with my gold? had one answer: hold it. Tokenization has made this answer much more extensive. Depositing it into lending pools, creating pairs on trading pools, putting it up as collateral, letting aggregators auto-compound it, putting it into a yield strategy that yields 3-15% + per year. Meanwhile, the metal is secure; it is stored in an audited vault.

This is not an entirely safe, risk-free upgrade for holding physical metal in DeFi. There are technical, counterparty, and regulatory risks that are increased and are well worth investigating, managing, and minimizing. But for investors who want their gold to work, for those investors who require the stability of a store-of-value on Gold, but also want some cash flow from productive investment, the ability is now possible. And that possibility is getting more robust, regulated, and efficient every year. The era of passive gold holding is over. The era of the productive investment of gold has just begun.
