Circle just sent $4 billion in USDC to Coinbase in a single transaction. That’s the largest USDC transfer ever recorded, and it happened on HyperEVM, not Ethereum mainnet.
The transfer, executed on June 12, isn’t just a big number for the sake of a big number. It’s a signal that stablecoin infrastructure is quietly being rebuilt around newer blockchain ecosystems, with Hyperliquid emerging as a serious contender for institutional-grade liquidity operations.
What actually happened
Circle, the issuer of USDC, moved roughly $4 billion to Coinbase-linked addresses on HyperEVM. The transaction is tied to Hyperliquid’s AQAv2 implementation, a system that handles USDC bridging and rebalancing at a 9:1 ratio between different layers of the protocol.
Circle was named the official USDC deployer on Hyperliquid roughly one week before this transfer took place. So the $4 billion move wasn’t spontaneous. It was the first major operational test of a newly formalized arrangement.
