On-chain data shows $50 million at risk as Tether’s Alloy shutdown deadline boils down to 5 forgotten gold vaults

Tether is winding down Alloy by Tether, a platform built around dollar-tracking aUSDT debt backed by Tether Gold collateral. Starting Sept. 17, customers who have not returned their aUSDT will no longer be able to recover XAUT through the platform.

The remaining exposure is far smaller than the aUSDT contract’s headline supply. Alloy’s official vault data showed five open collateral-mint positions with 399,088.74 aUSDT of debt and 194.41497 XAUT of collateral at 00:04:52 UTC on Aug. 10.

50 million tokens do not equal Tether’s live debt

Alloy’s token API and Etherscan both showed a maximum total supply of 50,000,005 aUSDT, a figure that does not represent open debt.

Alloy’s product documentation says unissued aUSDT can sit idle in the smart contract, while the vault API directly measures debt tied to open positions. The Aug. 10 debt was less than 0.8% of maximum supply.

Address counts also overstate what can be learned about affected customers. Alloy’s API showed 209 holder addresses, compared with 80 on Etherscan, and neither count maps to the five open positions. A customer may also control more than one whitelisted address.

The system has unwound substantially since the June 30 disclosure, which recorded 907,994.8205 aUSDT as issued and 470.4215 XAUT as collateral. The Aug. 10 API instead labels the obligation as open debt, which had fallen to 399,088.74 aUSDT, while collateral had dropped to 194.41497 XAUT.

Those point-in-time figures represent declines of about 56% and 58.7%, respectively.

Alloy says a collateral-mint-position holder must extinguish the full outstanding aUSDT balance to remove all remaining XAUT, and it documents a 25-basis-point return fee. Buying aUSDT on a secondary market does not confer rights to a specific position’s collateral.

Tether’s June 17 announcement says the Alloy recovery route becomes unavailable starting Sept. 17. Its announcement, platform notice and mint-and-return terms do not set out another operational recovery process after that date.

The stated consequence is loss of the Alloy recovery route. The existing terms say XAUT reflected in a position remains the customer’s, but is pledged to Tether AbT and is not held as a segregated asset in the customer’s name. Those terms, last updated in 2024, do not explain post-deadline disposition.

As of Aug. 10, the recovery clock covered five positions and 194.41497 XAUT. The balances can change before Sept. 17, but position holders have no published assurance of a platform route after the cutoff begins.
