The assessment is "likely_true" with high confidence based on strong, direct, and consistent evidence from multiple primary sources. Three separate reports from the reputable blockchain tracker Whale Alert (two on Twitter, one on Telegram) explicitly state that a transfer of 100 million USDC was made from the USDC Treasury to Coinbase. The sources even detail two separate transactions of this nature, which reinforces the claim that such transfers are occurring.These sources are highly relevant and authoritative for reporting on-chain events. While the provided Etherscan links, which would be the ultimate proof, do not have summaries that confirm the specific transaction, they also do not contradict the claim. The remaining sources are either irrelevant or provide only weak circumstantial context. Crucially, there is no conflicting evidence among the provided materials. The weight of the consistent, direct reporting from a trusted source makes it highly probable that the statement is true.
