$687.7M USDC Routed Through Unknown Wallet on Solana, On-Chain Records Show

Whale Alert flagged what appeared to be a roughly $687.7 million USDC transfer on Solana late Wednesday, but the on-chain record shows the same funds were actually moved twice within minutes through an intermediary wallet whose owner is not publicly identified.

According to Whale Alert’s transaction pages and linked on-chain records, 687,674,644 USDC was first transferred at 23:18:01 UTC from wallet F93W…RyAvf to wallet Ajv2…QmTe. About six minutes later, at 23:24:09 UTC, the exact same 687,674,644 USDC was sent from Ajv2…QmTe to wallet 9piy…mFVo.

That sequence indicates a pass-through movement — F93W…RyAvf to Ajv2…QmTe to 9piy…mFVo — rather than two separate whale transfers involving different sums. Whale Alert listed all three addresses as “unknown wallet.”

As of the reporting cutoff, there had been no public statement from Circle, the company behind the USDC stablecoin, nor from any exchange or other identifiable entity claiming ownership of the wallets or explaining the purpose of the transfers. That leaves the verified facts limited to what is visible on-chain and reported by Whale Alert: the blockchain was Solana, the amount was 687,674,644 USDC, and the same funds changed hands twice in quick succession.

USDC is a dollar-pegged stablecoin issued by Circle and used across multiple blockchains, including Solana. Transfers of that size draw attention because traders and analysts often watch large stablecoin movements for signs of treasury rebalancing, custody shifts or other large-scale settlements. But without labeled wallets or a public explanation from the parties involved, the transaction record does not establish who controlled the addresses or why the money moved.

The scale alone makes the transfers notable. Depending on Whale Alert’s conversion at the time, the amount was valued at roughly $687.4 million to $687.8 million. Still, the clearest takeaway is not simply that hundreds of millions of dollars’ worth of USDC moved on Solana, but that the same 687,674,644 tokens were routed through an unlabeled intermediary wallet in about six minutes, with no public identification of the parties behind the addresses.
