Fact Check
The claim is strongly supported by the original SolanaFloor X post (https://x.com/SolanaFloor/status/2054489553101058106), which is a dedicated Solana on-chain monitoring account that reported Circle minted another ~500 million USDC on Solana in the last 24 hours on 2026-05-13. The word 'another' in the post indicates this is a recurring event, consistent with PANews reporting that Circle minted 3.25 billion USDC on Solana in a single week in late April 2026, with multiple individual 500 million USDC mints. The Odaily article independently corroborates the same figure citing SolanaFloor as the monitoring source, and Binance Square and a secondary X post further echo the same data. No conflicting evidence was found. The minor uncertainty (7%) reflects that the primary source is an on-chain monitoring account rather than an official Circle announcement, and the exact 24-hour window cannot be independently verified without direct blockchain explorer data.
Summary

Circle minted about 500 million USDC on the Solana blockchain (high-speed public network) in the past 24 hours, according to monitoring by SolanaFloor. The issuance increases the circulating supply of the U.S. dollar-pegged stablecoin on Solana, a network widely used for trading, payments, and on-chain activity. In crypto markets, fresh stablecoin issuance is commonly watched as a sign of rising liquidity available for transfers, trading, and settlement across blockchain-based applications.
