Solana Stablecoin Supply Hits Record $17.39B as USDC and USDT Add Liquidity
Solana’s stablecoin market has reached another all-time high, with total supply climbing to approximately $17.39 billion as fresh USDC and USDT issuance adds more dollar-denominated liquidity to the network.
The latest figure represents a sharp increase from roughly $16.13 billion on September 24, putting the 24-hour gain at about $1.26 billion, or 7.8%. The move also extends a rapid sequence of new records, with Solana having reached approximately $16.87 billion on September 22.
Data reported by Solana Compass, citing Solana and SolanaFloor updates, also showed that the latest increase coincided with large amounts of new stablecoin issuance on the network.
USDC and USDT drive the latest supply increase
The two largest stablecoin issuers on Solana were responsible for more than $1.2 billion of fresh supply over the 24-hour period.
Circle minted approximately $751 million in USDC, while Tether issued about $530 million in USDT on Solana. Combined, the two issuers added roughly $1.28 billion in new stablecoins, slightly more than the network’s reported net increase of $1.26 billion.
Circle’s USDC is natively supported on Solana alongside dozens of other blockchain networks. Tether has also supported USDT on Solana for years, with the company first announcing the integration in 2021.
The difference between gross issuance and the net change in total supply can reflect movements such as redemptions, burns or changes in circulating balances elsewhere in the market. As a result, the two figures do not necessarily need to match exactly.
USDC remains Solana’s largest stablecoin
USDC continues to hold the largest share of Solana’s stablecoin market, accounting for approximately 47.31% of total supply.
That represents a notable change from earlier periods. The supplied data shows USDC’s dominance fell to around 44% last week, compared with a much higher 80.3% in February 2025.
At the latest reported levels, USDC represents approximately $8.23 billion of Solana’s stablecoin supply. USDT ranks second with approximately $2.66 billion.
The changing market share indicates that Solana’s stablecoin ecosystem is becoming less concentrated around a single dollar-backed asset. USDC remains the largest stablecoin on the network, but USDT and other assets contribute to a broader liquidity base.
Why stablecoin liquidity matters on Solana
Stablecoins provide blockchain-based representations of dollar-denominated value that can be transferred and used across decentralized applications. On Solana, they can be used for trading, lending, payments, settlement and other onchain activities.
Tether has described Solana as one of the networks supporting USD₮, while its developer documentation also provides tools for transferring USD₮ as a Solana token.
For users and applications, a larger stablecoin supply does not automatically mean that the entire amount is actively being traded or deployed in DeFi. Supply measures the amount of tokens outstanding, while actual usage depends on factors such as exchange activity, lending demand, payments and liquidity provision.
The distinction is important because the $17.39 billion figure represents stablecoin supply, not necessarily the amount being actively used in Solana applications at any given moment.
U.S. stablecoin regulation moves forward
The Solana supply milestone arrives as U.S. regulators continue developing the framework established by the GENIUS Act.
On September 24, the Federal Reserve proposed two rulemaking packages concerning payment stablecoin issuers supervised by the central bank. One proposal addresses reserves, capital requirements, risk management and the custody of assets backing stablecoins. The other establishes an application process for certain Federal Reserve-supervised banks seeking approval to issue payment stablecoins.
Under the first proposal, supervised payment stablecoin issuers would be required to fully back their tokens with permitted reserve assets, including short-term Treasury bills and certain other high-quality liquid assets. The Fed said the proposals were open for public comment for 60 days after publication in the Federal Register.
Solana enters a larger stablecoin market
The new supply record places Solana’s stablecoin market at a significantly higher level than it was earlier in the year. The latest expansion has been particularly notable because it followed two previous records within only a few days.
The immediate driver identified in the supplied data was fresh issuance from Circle and Tether, which together created roughly $1.28 billion in new USDC and USDT on Solana during the measured period.
At the same time, the market’s composition continues to change. USDC remains the largest stablecoin with about 47.31% of supply, while USDT represents another substantial portion at approximately $2.66 billion.
For Solana, the record highlights the growing scale of dollar-denominated assets circulating on the network. The next question is how much of that expanding supply translates into actual transaction, trading, lending and payment activity across the ecosystem.
