Tether Gold on Ethereum

XAUT, Tether Gold, one troy fine ounce of gold on a specific numbered bar in a Swiss vault, with that bar identified to the holder by serial number. Tether issues the token and runs the storage itself instead of renting a custodian, so nothing is deducted from the balance for storage. Tether launched it in 2020, running it through the same issuance and reserve operation as its dollar token.
