SOL rose toward $78 as the $500M mint boosted on-chain liquidity. The two-tranche structure suggests a pre-arranged custody move, traders said.
Alpha Score of 51 reflects moderate overall profile with strong momentum, poor value, moderate quality, moderate sentiment.
Circle’s USDC Treasury minted $500 million in USDC on the Solana blockchain in two $250 million tranches July 14. The first batch appeared in the morning session, the second in the afternoon. SOL rose toward $78, a level not seen since early June.
On-chain data from Dune Analytics shows total USDC supply on Solana now above $8 billion, the highest since April 2025. The mint comes as Solana’s DeFi ecosystem has absorbed an average of $150 million in new stablecoin liquidity each week over the past month. Circle’s large mints often coincide with institutional demand for onboarding to lending protocols or funding arbitrage flows between centralized exchanges and on-chain order books.
Traders monitoring the block explorer said the two-tranche structure suggested the mint was pre-arranged with a large custody client rather than a reaction to spot volatility. The funds landed in a handful of whale addresses, each receiving between $50 million and $100 million, according to Solscan data. No single address took more than $100 million, limiting the risk of a sudden redemption.
The event echoes a pattern from May, when Circle minted $400 million USDC on Solana and SOL rallied 12% over the following week. This time the mint is larger. The market is also deeper. Solana’s total value locked in DeFi has added $1.2 billion since that mint, giving the ecosystem more room to absorb the new supply without pushing the stablecoin’s peg.
Traders said the next 48 hours would show whether the fresh USDC signals a wave of institutional buying or merely a custodial reshuffle. If whale addresses move the funds into lending pools or DEX liquidity, the rally has a foundation. If the addresses hold idle, the price move could fade.
