The claim is strongly supported by multiple independent, on-chain-linked sources. The original @whale_alert X post (2026-05-13T23:25:15Z) reports exactly 138,069,915 USDC (138,022,419 USD) transferred from Aave to Unknown Whale 1, matching the claim's figures precisely. The Whale Alert transaction page for tx hash 0xdab2505b...eed7 confirms the on-chain details: sender is the Aave contract (0x98c23e9d...), receiver is Unknown Whale 1 (0x56957e41...), timestamped 2026-05-13T23:23:59Z. Two additional Whale Alert transaction pages (0x7cb...5b8c and 0xfe5d...372e) show the same whale address conducting further large USDC movements with Aave, corroborating the whale's identity and the authenticity of the original transaction. All figures, addresses, and timestamps are internally consistent. The minor residual uncertainty (3%) reflects the fact that Etherscan's raw blockchain data was not directly fetched to independently verify the transaction hash, though Whale Alert's data is derived from on-chain records.
