Tether minted $500 million in USDT on Solana in under 60 minutes on September 19, while Circle issued $250 million in USDC on the same network. The combined $750 million issuance, independently confirmed for USDC through Whale Alert monitoring and a transaction hash cited by PANews, points to converging demand for on-chain stablecoin liquidity. Solana Compass data put Solana’s USDT supply at $3.84 billion across 3.04 million wallets and USDC supply at approximately $7.7 billion across 9.08 million wallets, for more than $11.5 billion combined. The issuances followed Solana stablecoin transfer activity reaching a reported $20 billion annualized level and daily active stablecoin addresses rising to 888,000 earlier in September, up 269% year over year. Stablecoin mints generally occur after counterparties provide collateral and request tokens, potentially reflecting demand from exchanges, trading desks and protocols.
