Stablecoin issuer Tether expanded the circulating supply of its dollar-pegged USDT token by about $3 billion in less than 24 hours, blockchain data show. The firm minted 1 billion USDT on Ethereum late on 16 July and followed with two additional 1 billion issuances on 17 July, representing one of the largest single-day increases in the token’s history. The creation of new tokens came alongside heavy flows between Tether Treasury wallets and major trading venues. Addresses linked to Binance sent roughly $1.46 billion in USDT to the Treasury on 17 July and later received about $1.3 billion, while wallets associated with HTX moved about $1.6 billion in both directions. Smaller transfers involving about $200 million originated from the Aave lending protocol. Such movements typically precede the release of freshly minted stablecoins into exchange inventories. USDT was not the only stablecoin showing unusual on-chain activity. The USDC Treasury burned and immediately re-issued about $139 million of USDC before minting two separate 250 million batches later the same day, bringing new USDC supply to roughly $639 million.
