Multiple credible and relevant sources report large USDC transfers, with Whale Alert data cited in both news and social media posts. The Reddit/Twitter discussion explicitly references a $403 million USDC transfer between unidentified wallets, and transaction tracking services like Whale Alert are widely recognized for accuracy in reporting on-chain movements. Additional crypto news reports mention other large USDC transfers in the hundreds of millions, demonstrating that transactions of this magnitude are plausible and occur regularly. Although some sources provide figures for different amounts (e.g., $200M, $309M), this does not contradict the existence of a separate $403M transfer; rather, it strengthens the context for such events. The $403M specific figure appears in a high-relevance, moderately authoritative source with direct reference to transaction tracking data, and there is no evidence directly refuting it. Given consistency with known transfer patterns and credible reporting, the statement is highly likely to be true.
