Finassets.io Launches USDC on Solana to Slash Crypto Payment Costs for Merchants

Finassets.io has integrated USDC on the Solana network into its B2B payment infrastructure, addressing the critical need for high-throughput, low-cost stablecoin settlements. For fintech professionals, this move signals a shift toward network-specific efficiency in crypto-acquiring, prioritizing transaction speed and reduced gas fees to make digital asset payments viable for high-volume merchant operations.

What was announced

Finassets.io, a crypto payment gateway provider, has officially added support for USDC (SOL) to its Back Office environment. This integration allows merchants to accept and process USDC via the Solana blockchain alongside the 70+ other cryptocurrencies already supported by the platform. The functionality is delivered through the existing Finassets infrastructure, meaning businesses can utilize their current payment buttons, checkout interfaces, and API integrations without requiring a separate technical overhaul.

The decision to support Solana is driven by the network's specific performance metrics. Solana currently holds the second-largest share of circulating USDC, trailing only Ethereum, with approximately $6.7 billion of Circle’s total supply residing on the chain. The integration leverages Solana’s high-throughput architecture, which has maintained uptime without an outage for over two years. By utilizing this network, merchants can bypass the higher costs and slower confirmation times typically associated with Ethereum-based transactions.

Operationally, USDC (SOL) payments benefit from the Finassets "Auto-Convert" feature. This tool automatically converts incoming crypto payments into stablecoins the moment they arrive, fixing the exchange rate to shield merchants from market volatility. Once a transaction is confirmed on the network, deposits are typically credited to the merchant’s account within 30 seconds. The system maintains enterprise-grade security standards, including Multi-Party Computation (MPC) wallet technology, two-factor authentication, role-based access control, and IP whitelisting.

"USDC on Solana is one of the most efficient stablecoin payment options available today. It combines a widely used dollar stablecoin with one of the fastest and lowest-cost networks. We added it to give merchants a faster, more cost-effective way to move USDC, especially when they’re processing payments at scale."

The companies involved

Finassets.io operates as a B2B crypto payment infrastructure provider, focusing on bridging the gap between traditional commerce and digital assets through a unified Back Office suite. The company provides the underlying rails for businesses to accept, manage, and convert various cryptocurrencies into stable assets, emphasizing security through MPC-based custody solutions.

The integration centers on USDC, a leading dollar-pegged stablecoin issued by Circle. Circle has recently solidified its position as a dominant force in the blockchain space, notably becoming the top U.S. blockchain patent holder after acquiring a significant portfolio from IBM. Solana, the network chosen for this expansion, is a high-performance blockchain designed for scalability and low-cost transactions, positioning itself as a direct competitor to Ethereum. Ethereum remains the foundational smart contract platform and the largest host of USDC by volume, though it often faces criticism for higher transaction fees during periods of network congestion. By offering USDC on both Solana and Ethereum, Finassets allows merchants to choose the network that best fits their cost and speed requirements.

What FF News has reported before

FF News has closely monitored the evolution of stablecoin infrastructure and the growing dominance of Circle in the digital asset ecosystem. We recently covered how Circle Becomes Top US Blockchain Patent Holder Following IBM Portfolio Acquisition, a move that underscores their long-term commitment to blockchain R&D. The trend toward stablecoin-centric treasury management was also highlighted in our report on how Thunes Expands Web3 Infrastructure with EURC for Instant Euro Treasury Funding.

Furthermore, our reporting has noted the surge in corporate interest in these assets, as seen in Stablecoins Hit 60% of Mercuryo Purchase Volume as B2B Adoption Surges. We also tracked the intersection of AI and payments in Rain Unites Visa, Mastercard, and Fiserv to Launch Agentic Payments Alliance for AI Commerce, reflecting a broader industry shift toward automated, programmable financial rails.

What this means

This move by Finassets.io is a pragmatic acknowledgment that the "network effect" of Ethereum is no longer enough to keep merchants loyal if transaction costs remain prohibitive. By promoting Solana as a primary rail for USDC, Finassets is putting pressure on other gateway providers to diversify their network support or risk losing high-volume B2B clients to more efficient alternatives. For merchants, the 30-second settlement time is the real headline; it brings crypto payments closer to the "instant" experience of modern fintech apps. Watch for whether Ethereum’s Layer 2 solutions can respond quickly enough to Solana’s growing dominance in the stablecoin settlement layer.
