DeFi Tokenized Commodities: Lending, Collateral and Yield

Learn how DeFi tokenized commodities like PAXG and XAUT work as collateral, generate 3–5% APR, and reached $5 billion in 2026.

Introduction

DeFi tokenized commodities transform physical assets such as gold and silver into blockchain-based tokens that lending protocols can use directly as collateral. Each token represents ownership of a specific quantity of a real-world asset, like one troy ounce of vaulted gold, and follows common token standards such as ERC-20. This structure connects traditional commodity markets with decentralised finance, enabling borrowing, lending, and yield strategies around metal-backed tokens.

The article explains how tokenized commodities are created, how gold-backed tokens function as collateral in major DeFi protocols, and how yield strategies work. It outlines the main tokens and protocols involved, including PAXG, XAUT, Sky Protocol, Aave, and Morpho, then examines key risks and regulatory questions. The final sections review market growth figures and regulatory developments to show how tokenized gold now fits into the broader RWA landscape.

What Are Tokenized Commodities and How Do They Work on Blockchain?

Tokenized commodities are digital tokens on a blockchain that represent direct ownership of a physical asset, such as gold, silver, or oil. The tokenization process converts these traditionally illiquid physical assets into programmable tokens that DeFi protocols can use directly.

The process works in three steps. First, a regulated custodian takes physical ownership of the commodity and stores it in an audited facility — for example, Paxos holds allocated gold bars in LBMA-accredited vaults. Second, a blockchain issuer mints an ERC-20 token (a standard token format on the Ethereum network) pegged 1:1 to the stored asset. Third, smart contracts — self-executing programs on the blockchain — govern all issuance, transfers, and redemptions automatically. When a holder redeems tokens, the smart contract burns them and releases the equivalent physical asset or its cash value.

Two main models exist for tokenized commodities. Physically backed tokens, such as PAXG (Pax Gold, issued by Paxos) and XAUT (Tether Gold, issued by Tether), hold real gold in vaults and redeem tokens directly against that gold. Synthetic tokens track commodity prices algorithmically through derivatives or price oracles, without holding the physical asset. Because physically backed tokens follow the ERC-20 standard, they integrate natively into Ethereum-based DeFi protocols — such as Aave or Uniswap — without requiring additional bridges or adaptations.

What Are the Main Tokenized Commodity Tokens Available in DeFi Today?

Two gold-backed tokens dominate the tokenized commodity market in DeFi: PAXG (Pax Gold) and XAUT (Tether Gold). PAXG is issued by Paxos Trust Company, an NYDFS-regulated entity, and each token represents one fine troy ounce of gold held in LBMA-accredited vaults. XAUT, issued by Tether, similarly pegs each token to one troy ounce of gold stored in Swiss vaults as London Good Delivery bars, with over 520,000 troy ounces in reserve as of end-2025. Together, PAXG and XAUT control the dominant share of the tokenized gold market, which reached approximately $5.3 billion in total market capitalisation as of March 2026.

Beyond gold, Kinesis Silver (KAG) offers silver-based commodity tokenization with a circulating market cap of approximately $265 million as of early 2026. Kinesis Silver tokens are pegged 1:1 to one gram of allocated silver and are designed for both investment and direct spending via a Mastercard-linked card. These tokens represent a smaller but growing segment of the tokenized commodity market, with DeFi integration remaining more limited than the dominant gold tokens.

Data current as of April 2026.

PAXG's deeper DeFi integration reflects its longer on-chain history and stronger DEX liquidity, concentrated primarily in the Uniswap ETH/PAXG pool. XAUT has expanded its multi-chain presence significantly, launching natively on Avalanche in 2025, Polygon in August 2025, and BNB Chain in March 2026. This multi-chain strategy broadens XAUT's accessibility but its DeFi protocol integration — particularly in lending — remains less developed than PAXG's.

How Does Gold Work as DeFi Collateral in Lending Protocols?

Gold-backed tokens work as DeFi collateral by allowing holders to lock their tokens in a lending protocol and borrow stablecoins — such as DAI or USDC — against that position. The holder retains exposure to the gold price without selling the asset, while the protocol holds the tokens as security for the loan. This is over-collateralization in practice: a borrower must deposit more value in collateral than the value they borrow.

The core mechanic relies on two key parameters. The loan-to-value ratio (LTV) defines the maximum borrowing limit — an LTV of 70% means a borrower holding $1,000 of PAXG can borrow up to $700 in stablecoins. The liquidation threshold sets the point at which the protocol automatically sells part of the collateral to repay lenders — if the collateral value falls below this threshold, smart contracts execute the liquidation without any manual intervention.

How Does MakerDAO Use PAXG as Collateral?

MakerDAO, now rebranded as the Sky Protocol, was among the first major DeFi lending protocols to accept PAXG as collateral for minting DAI, its decentralised stablecoin. A user deposits PAXG into a MakerDAO vault and the protocol mints DAI up to the permitted collateralization limit — the minimum collateralization ratio under the system is 150%, meaning $1.50 of collateral backs every $1.00 of DAI issued. MakerDAO's broader real-world asset (RWA) integration has since grown substantially, with approximately $948 million in RWA-backed collateral representing 14% of total protocol reserves as of mid-2025.

MakerDAO's RWA strategy positions commodity-backed tokens as a stabilising component of the protocol's collateral mix. Unlike volatile crypto assets, tokenized gold tracks the physical gold spot price, which has historically lower short-term volatility than ETH or BTC. This characteristic makes PAXG a lower-risk collateral type, allowing the protocol to accept more conservative liquidation parameters.

What Are Aave's Proposed Parameters for PAXG Collateral?

In November 2024, an Aave Request for Comment (ARFC) proposed adding PAXG to Aave v3's main Ethereum instance. The proposal specified an LTV of 70%, a liquidation threshold of 75%, a 6% liquidation bonus, a supply cap of 500 PAXG, and a debt ceiling of $900,000. Under isolation mode — a risk-containment feature that limits how much debt a single collateral type can generate across the protocol — PAXG would function as collateral only, with no direct borrowing of PAXG enabled.

The proposal recommended using the XAU spot price oracle (the gold market benchmark) rather than the PAXG token market price. This approach reduces the risk of weekend oracle gaps, which occur when on-chain token prices diverge from physical gold prices while traditional commodity markets are closed. At the time of writing, the proposal remained in governance review; readers should check Aave's governance forum for the current status.

What Are the Different Ways to Generate Yield from Tokenized Commodities in DeFi?

Tokenized commodity holders can generate yield through four main strategies in DeFi. Unlike high-risk liquidity mining that pays rewards in native governance tokens, most gold-based strategies derive income from real economic activity — lending demand or institutional gold leasing. This structural difference makes the yields lower but more predictable, typically in the 3–8% annual range.

The first strategy is lending protocol deposits: a holder supplies PAXG or XAUT to a lending protocol such as Morpho, where borrowers pay interest to use the token as collateral. Morpho's PAXG/USDC market, for example, held approximately $1.71 million in active USDC loans backed by PAXG collateral as of early 2026. The second strategy is liquidity provision (LP): a holder pairs PAXG with USDC in a decentralised exchange (DEX) pool on Uniswap, earning a share of the trading fees generated by every swap through that pool. The PAXG/USDC pool on Uniswap carried a TVL of approximately $4 million with a 2.98% total APR as of March 2026.

The third strategy is gold leasing vaults: Falcon Finance launched an XAUt staking vault in December 2025 that mirrors institutional gold leasing. Users lock XAUt for a 180-day fixed term and earn 3–5% APR paid weekly in USDf — Falcon's multi-asset-backed synthetic dollar — while retaining legal ownership of the locked tokens. The fourth strategy is the collateral loop: a user deposits gold tokens as collateral, borrows stablecoins against them at an LTV below the liquidation threshold, and deploys those stablecoins into a separate yield strategy such as a stablecoin lending pool. This amplifies returns but also compounds liquidation risk if gold prices fall sharply.

Data current as of April 2026.

The yields from physically backed gold tokens are structurally lower than speculative DeFi farming, which routinely offered double-digit APYs through token emissions during earlier market cycles. However, gold-based yields carry no inflation from new token issuance — every basis point of return comes from an actual counterparty paying to borrow or trade the asset. This characteristic aligns tokenized gold yield strategies more closely with traditional gold leasing rates in institutional commodity finance, which have historically ranged from 0.1% to 3% per year.

What Risks Should You Consider When Using Tokenized Commodities as DeFi Collateral?

Using tokenized commodities as DeFi collateral carries four distinct risk categories. Each risk operates independently, meaning a position can face multiple risk types simultaneously. Understanding these categories helps users set conservative collateral ratios and choose protocols with robust safety mechanisms.

Liquidation risk is the most immediate threat. If the gold price drops sharply and the collateral value falls below the protocol's liquidation threshold, smart contracts automatically seize and sell part of the collateral to repay lenders — with no manual override possible. A sudden 10% intraday move in gold prices, while uncommon, is sufficient to trigger liquidation on a position near the threshold. The Aave PAXG proposal's recommended 75% liquidation threshold provides only a five percentage-point buffer above the 70% LTV, requiring active position monitoring.

Smart contract risk affects every DeFi protocol. Vulnerabilities in protocol code can allow attackers to drain funds — DeFi exploits cost over $59 billion between 2020 and 2024, with lending platforms accounting for 195 reported incidents. The February 2025 Bybit hack, the largest single DeFi exploit in history, resulted in approximately $1.4 billion in losses through a supply chain attack on signing infrastructure. Even audited protocols carry residual risk: 66% of reported DeFi hacks between 2020 and 2024 involved previously audited code.

Oracle risk arises when the price feed that a protocol uses to value collateral becomes inaccurate or is manipulated. In March 2026, a faulty oracle update on Aave caused collateral to be undervalued by 2.85%, triggering approximately $21.7 million in liquidations across 34 accounts — all of which were healthy positions at actual market prices. For gold tokens specifically, weekend oracle gaps present a structural vulnerability: on-chain token prices can diverge from physical gold spot prices when traditional commodity markets are closed, exposing collateral positions to mispricing.

Custodial and counterparty risk is unique to physically backed tokens. The user must trust that the issuer holds sufficient physical gold in its vaults, conducts regular independent audits, and can honour redemptions under stress conditions. PAXG and XAUT both publish periodic attestation reports, but these are not continuous real-time audits — a gap exists between attestation dates. Additionally, tokenized gold tokens can temporarily trade at a discount to the gold spot price during periods of market stress, a condition called depeg risk, which further erodes collateral value independent of the physical gold price.

How Do DeFi Protocols for Tokenized Commodities Compare Across Key Features?

Three protocols currently lead the integration of tokenized commodity collateral in DeFi: Sky Protocol (formerly MakerDAO), Aave v3, and Morpho. Each uses a different governance model and applies distinct risk parameters to RWA collateral. Understanding these differences helps users select the most appropriate platform for their lending or yield strategy.

Sky Protocol takes the broadest approach to RWA integration. Its vault system accepts both crypto and RWA collateral — including commodity-backed tokens — while governance decisions flow through SKY token holders and a system of semi-autonomous sub-units called Stars. Aave v3 uses a more conservative on-boarding mechanism: new or untested collateral types, including gold tokens, must enter through isolation mode — a feature that restricts the borrower to specific approved stablecoins and enforces a hard debt ceiling, preventing a single new asset from generating systemic protocol-wide risk. Morpho takes a permissionless approach, allowing anyone to create a lending market with custom parameters for any token pair, including PAXG/USDC, without requiring a governance vote.

Data current as of April 2026.

Aave's isolation mode is particularly relevant for commodity tokens entering DeFi for the first time. The $900,000 debt ceiling proposed for PAXG caps total protocol exposure, so even a complete collateral failure could not threaten overall protocol solvency. Morpho's permissionless model offers flexibility but transfers risk management responsibility to market curators — independent risk managers who set parameters for each market — rather than a protocol-wide governance body. Sky Protocol's deeper RWA integration reflects its longer history with off-chain asset collateral, but its auction-based liquidation system is more complex than Aave's automated price-threshold model.

What Are the Primary Use Cases for Tokenized Commodity Lending in Institutional and Retail Finance?

Tokenized commodity lending serves distinct purposes for institutional and retail participants. Institutional users focus on capital efficiency — extracting liquidity from commodity holdings without disrupting their core positions. Retail users focus primarily on access — gaining fractional exposure and yield opportunities that traditional commodity markets typically reserve for large investors.

On the institutional side, three use cases dominate. First, mining companies can tokenize their gold reserves and borrow stablecoins against those holdings to fund operational costs — covering equipment purchases or payroll — without liquidating physical gold at unfavourable prices. AMA-AMBIOGEO demonstrated this model in September 2024, tokenizing $4.6 billion in gold reserves using the ERC-3643 standard with planned DeFi integration. Second, trading desks use PAXG and XAUT as on-chain margin collateral, posting tokens to protocols rather than transferring cash between counterparties, which reduces settlement delays from days to seconds. Third, corporate treasuries holding gold as a reserve asset can deploy idle commodity positions into gold leasing vaults — such as Falcon Finance's XAUt vault — earning 3–5% APR on assets that would otherwise generate no income.

Retail users access two primary benefits. A holder of PAXG can borrow stablecoins against their gold position without triggering a taxable disposal event in jurisdictions that treat borrowing differently from selling — borrowing against an asset is not a taxable sale in many regulatory frameworks, though users should verify rules in their own jurisdiction. PAXG also enables fractional gold exposure: since each token represents one troy ounce but trades in fractions on-chain, a retail investor can access as little as $1 worth of gold-backed collateral, far below the minimum for physical bullion. The broader RWA lending market supporting these use cases reached over $579 million in active DeFi loans as of mid-2025, generating an average yield of 9.65% to credit protocols, according to RWA.xyz data.

How Has the Tokenized Gold Market Grown and What Do the Numbers Show?

The tokenized gold market expanded at an exceptional pace in 2025, growing 177% in market capitalisation from approximately $1.6 billion to $4.4 billion over the year. This growth accounted for roughly 25% of all net RWA (real-world asset) growth in 2025 — outpacing inflows into tokenized stocks, corporate bonds, and non-US treasuries combined. By January 2026, the combined tokenized gold market cap crossed $5.1 billion for the first time, and reached approximately $5.45 billion as of March 2026.

Trading volumes confirmed this momentum. In Q4 2025, tokenized gold trading volume surged 345% quarter-on-quarter, exceeding $126 billion and surpassing the combined 24-hour trading volume of five major physical gold ETFs. XAUT held the larger share of that volume, with Tether reporting its gold token accounted for more than half of the entire gold-backed stablecoin market as of January 2026. The broader DeFi lending sector — within which tokenized commodity collateral sits — recorded total value locked (TVL) rising from $48.15 billion to over $82 billion between January and December 2025.

Data current as of April 2026.

The growth trajectory reflects two converging forces. Rising physical gold prices — spot gold reached a record high in 2025 — mechanically inflated the market cap of physically backed tokens, since each token is pegged to one troy ounce. Simultaneously, new on-chain use cases in lending and yield generation attracted net inflows beyond price appreciation alone, with tokenized gold growing 2.6 times faster than physical gold prices during 2025. DeFi lending TVL growth — reaching over $82 billion by end-2025 — created additional demand for stable, non-volatile collateral assets, and tokenized gold increasingly filled that role.

What Regulatory Frameworks Currently Apply to Tokenized Commodities in DeFi?

The regulatory treatment of tokenized commodities in DeFi depends on how a token is legally structured, not simply what physical asset it represents. Under the US Commodity Exchange Act (CEA) — the primary federal law governing commodity markets — a physically delivered token like PAXG may qualify as a commodity itself, while a token that functions as a derivative on a commodity price may instead be classified as a commodity interest, triggering far stricter CFTC oversight and compliance requirements. Cadwalader's September 2025 analysis identified four possible legal classifications for commodity tokens under the CEA, noting that the same asset could attract different regulatory treatment depending on whether its smart contract structure created a direct ownership claim or an indirect economic exposure.

In March 2026, the SEC and CFTC jointly issued interpretive guidance establishing a five-part taxonomy for crypto assets. Under this framework, tokenized commodities that confer direct, deliverable ownership of a physical asset are classified as digital commodities and fall primarily under CFTC jurisdiction, while tokenized structures that derive value from another security remain subject to SEC oversight. The CFTC reinforced this direction in December 2025, issuing formal guidance permitting tokenized assets — including commodity-backed tokens — to serve as eligible collateral in futures and swap markets, provided the underlying RWA meets existing margin eligibility standards.

Paxos operates PAXG under the most robust US regulatory framework currently available for a gold token. Paxos holds an NYDFS trust charter — granted in 2019 when it became the first company to receive NYDFS approval for a gold-backed token — and obtained an OCC national trust charter in December 2025, making PAXG the only gold-backed token issued under federal regulatory oversight. However, NYDFS fined Paxos $26.5 million in August 2025 for anti-money laundering deficiencies, resulting in a $48.5 million total settlement including compliance commitments. Paxos committed $22 million toward remediation, including enhanced transaction monitoring and independent audit requirements.

The compliance picture for DeFi protocols integrating tokenized commodities remains unresolved. When a permissionless DeFi protocol accepts PAXG as collateral, no single regulated party controls the lending transaction — creating ambiguity about which entity bears AML and KYC obligations. Regulatory requirements also vary significantly by jurisdiction: the EU's MiCA framework treats asset-referenced tokens differently from commodity tokens, while Singapore's Securities and Futures Act applies case-by-case based on token structure and embedded rights. Protocol builders and institutional users entering this space should monitor national regulatory guidance closely, as classification decisions made in 2025–2026 will shape market structure for years ahead.
