Half of DeFi's tokenized gold sits in Aave. The whole pool is $63 million.

Aave V3 now holds more than 50% of all tokenized gold deposited across decentralized lending protocols, according to Crypto Briefing ^[1]. The concentration is real, but the more useful number is the denominator: combined PAXG and XAUT collateral across Aave V3 and Morpho stood at roughly $63 million in early-to-mid 2026, against a combined market capitalization of about $4.2 billion for the two tokens ^[2][3].

That works out to about 1.5% of tokenized gold supply doing any work as collateral ^[4], which is what the arithmetic on those two figures produces ^[1]. Because the $63 million covers only two venues, Aave's majority share of the full DeFi total implies it holds more than $31.5 million of gold tokens ^[2]. A protocol can be dominant in a category and still be talking about a position smaller than a single mid-size treasury allocation. Concentration risk is usually framed as a systemic worry; here the pool is too small for the dominance to mean much either way.

How Aave got there is unremarkable in the good sense. PAXG has been accepted as collateral on the Ethereum deployment of Aave V3 since launch ^[5], and governance proposals to add Tether's XAUT to the core instance began circulating in mid-2025 ^[6]. Isolation mode, shipped in 2022, let the protocol onboard thinner assets under tighter risk parameters ^[7]. During a stress event in March 2026, Aave V3 processed XAUT liquidation clusters without significant disruption ^[8]. That is the sort of evidence that earns share in a niche: the plumbing held when it was tested.

The trust model is the part that does not resolve with better parameters. PAXG is backed by London Good Delivery bars held in Brinks vaults, XAUT by gold in Swiss vaults, and both issuers publish attestations ^[9][10]. That is a different risk shape from holding ETH, and it sits underneath every liquidation the protocol runs ^[11].

Set the collateral figure against activity and the picture sharpens. Tokenized gold trading volumes passed $90 billion in Q1 2026 ^[12], roughly 21 times the combined market cap of the two tokens in a single quarter ^[3], while the collateral posted across Aave and Morpho equals about 0.07% of that quarterly volume ^[4]. Gold tokens are being traded heavily and pledged almost not at all. The demand so far is for a liquid proxy on gold price, not for a borrowing base.

What to watch is whether that changes, and 1.5% is the tracking number. Crypto Briefing notes that moving to 5% utilization of the $4.2 billion market cap would put roughly $210 million into deployed collateral ^[13], more than triple the current level ^[14] and an increase of about $147 million ^[5]. Watch also whether the concentration erodes: Morpho already shows up alongside Aave in the collateral data ^[15], and a visible majority share in a growing category is an invitation to competitors ^[16]. If gold-token supply keeps growing while utilization stays near 1.5%, the honest read is that these are trading instruments that happen to be listed on lending markets, not collateral in any load-bearing sense.
