Circle completed two mint transactions on Solana, creating 500 million USD Coin (USDC) in a new issuance batch whose later circulation is not established by the mint itself.
Each transaction created 250 million USDC, and the mints were completed 12 minutes apart. The total came from two equal transactions rather than one mint for the full amount.
A mint confirms token creation, but does not show what happened to the tokens afterward. Issuance alone does not establish that all the USDC entered circulation or reached trading venues, so the 500 million figure is not a measure of confirmed market activity.
Separately, SolanaFloor's tally put Circle's USDC issuance on Solana at about $750 million over the 24 hours through Oct. 15. That figure covered a different period of issuance on the network.
