Solana's ecosystem experienced a surge in stablecoin liquidity, institutional adoption, and network maturity during mid-2026. This article provides a fact-checked summary of the key developments, distinguishing between claims that are directly supported by available sources and those that remain unverified.

Circle's Record-Breaking USDC Mints on Solana

Circle's USDC issuance on Solana accelerated throughout 2026, with multiple billion-dollar mints occurring within narrow timeframes.

$1 Billion Mints in a Single Day — By mid-June 2026, Circle had minted $1 billion USDC on Solana within a 24-hour window, bringing the cumulative 2026 gross issuance to approximately $57 billion . On June 16, another reported $1 billion mint pushed the weekly total to $3.5 billion .

Record Weekly Issuance — In early April 2026, Circle minted $3.25 billion USDC on Solana in a single week, described as the largest single-week stablecoin minting volume recorded in 2026 . This pushed Solana's total USDC supply past $8.64 billion .

Accelerating Pace Throughout the Year — The accelerating trend is supported by a progression from $1.75 billion in the first week of January to $38 billion by mid-April and $57 billion by mid-June . The $64.25 billion figure mentioned in the initial query could reflect subsequent July mints, but it is not directly confirmed in the provided sources.

SoFiUSD: A Bank-Issued Stablecoin Driven by Solana

SoFi's entry into the stablecoin market marked a milestone for regulated digital dollars, with Solana playing a central role in its growth.

Initial Rollout — SoFiUSD (ticker: SOFID) launched on Ethereum in December 2025 . On April 2, 2026, SoFi announced its deployment on Solana alongside the SoFi Big Business Banking platform, citing Solana's low transaction costs, settlement speed, and throughput .

Consumer Launch — On May 27, 2026, SoFi opened SoFiUSD access to its 14.7 million to 15 million banking app customers, making it the first stablecoin deployment by a nationally chartered U.S. bank to retail consumers on a public, permissionless blockchain .

Rapid Supply Growth on Solana — The token's market cap reached approximately $100 million in late May 2026, available on both Ethereum and Solana . By June 30, 2026, SoFiUSD's circulation had tripled to exceed $300 million, with over $200 million deployed on Solana while the Ethereum supply remained flat . The report attributed this growth to Solana's extremely low transaction costs, confirming that all incremental growth was driven by Solana .

Grayscale Report: Solana Matures into a High-Capacity Network

Staking Metrics — While the initial query cited ~68% of SOL staked, multiple sources provide a range: approximately 65% is confirmed by Solana overviews , while on-chain data from Solana Compass shows 67.9% as of July 1, 2026 . A Staking Rewards snapshot indicated 68.42% of eligible circulating supply as of early January 2026 . The 68% figure is broadly supported but varies by measurement date.
