Key Highlights
- Circle minted $3.25 billion in USDC on Solana over the past week — the largest weekly issuance of 2026 — through repeated large transactions, many hitting the $250 million mark, with daily volumes reaching up to $750 million.
- The fresh USDC supply is flowing into one of crypto’s fastest-growing ecosystems, where low fees and high throughput are fueling surges in stablecoin transfers, decentralized trading, lending protocols, and institutional on-chain activity.
- With a total supply of approximately $77.5 billion (roughly 24-25% of the $315+ billion stablecoin market), USDC trails Tether’s dominant $184 billion USDT but continues gaining in regulated use cases; Solana now holds $7.7 billion in USDC, the second-largest chain allocation after Ethereum.
Circle has minted $3.25 billion in USDC on the Solana blockchain over the past seven days, marking the biggest weekly injection of the stablecoin this year. The issuances came in a series of large transactions, with all including the mining amount of 250 million mark.
On-chain data from Solscan, the blockchain explorer for Solana, shows repeated mints from Circle’s treasury address, with daily volumes spiking as high as $750 million in recent sessions.
This fresh supply is landing directly into one of crypto’s most active ecosystems, where low fees and high speed have drawn traders, DeFi protocols, and institutional players.
The move reflects strong underlying demand for dollar-denominated liquidity on Solana. In recent months, stablecoin transfers on the network have surged, often outpacing older chains in daily volume for certain use cases. Market observers see the minting as a direct response to rising activity in decentralized trading, lending platforms, and on-chain settlements.
USDC supply and dominance
Solana’s total USDC supply has grown steadily throughout 2026, bolstered by Circle’s consistent support. Over the past month alone, issuances have topped $10 billion on the chain.
USDC currently commands a total supply of approximately $77.46 billion, representing roughly 24-25% of the overall stablecoin market, which now exceeds $317 billion.
While Tether’s USDT maintains clear dominance with a market cap near $184 billion and about 58% share, Circle’s USDC continues to gain ground in regulated, high-volume use cases.
Data from DeFiLlama shows Solana hosting roughly $7.68 billion in USDC—the second-largest allocation after Ethereum’s $51.52 billion—highlighting the network’s rising importance for the stablecoin.
Although USDT still leads in retail remittances and emerging markets, USDC processes significantly higher transfer volumes relative to its size, appealing to institutions and DeFi protocols that prioritize transparency and compliance.
The fresh liquidity on Solana could help narrow the gap further by boosting trading and lending activity where speed and low fees matter most.
