While blockchain data from March 9-10, 2026, confirms massive USDC movements (including 350M and 100M transfers), the specific figure of $236 million between 'unknown wallets' could not be independently verified through search results for the provided transaction IDs. The transaction IDs themselves appear to be valid formats for Solana and Ethereum, but their specific contents (amounts and wallet labels) were not accessible via the tools. The claim is plausible given the high volume of stablecoin activity on this date, but the exact $236M figure lacks direct corroboration.
