Finassets Adds USDC on Solana to Payment Gateway Supporting 70 Crypto Options

Crypto payment gateway Finassets.io launched USDC support on Solana today, giving merchants a sub-cent settlement option inside the same Back Office dashboard they use to manage 70-plus other cryptocurrencies.

The addition is straightforward in scope but pointed in its timing. Stablecoin payment volume has climbed steadily through 2026, and merchants processing high transaction counts are increasingly sensitive to network fees. Solana's average transaction cost sits well below $0.01, compared to Ethereum mainnet fees that can spike into dollars during congestion. For a merchant running thousands of monthly settlements, that spread is material.

"Solana is among the fastest, lowest-cost networks for settling USDC today."

Solana's throughput capacity exceeds 65,000 transactions per second, a figure that positions it ahead of most competing layer-1 and layer-2 networks for raw settlement speed. Merchants using the Back Office can now route USDC payments through Solana without switching platforms or managing separate wallets, which reduces operational friction for businesses already embedded in the Finassets stack.

Circle, the issuer behind USDC, has pursued a multi-chain deployment strategy that now spans more than a dozen networks. Payment processors that want to capture stablecoin volume have little choice but to follow. Stripe explored Solana-based USDC payouts as early as 2023, signaling that merchant appetite for low-cost stablecoin rails predates the current wave of integrations.

Finassets faces real competitive pressure. Polygon, Arbitrum, and Base all offer comparable fee profiles for USDC settlement, and several rival gateways already support those chains. Solana also carries a reliability caveat: the network logged multiple outages between 2021 and 2023, and while uptime has improved significantly, some enterprise merchants remain cautious. USDC circulation on Solana is also smaller than on Ethereum, meaning customer-side familiarity with the chain is still developing. Regulatory ambiguity around stablecoin payments in the EU and several Asian markets adds another layer of uncertainty for merchants operating across borders.

"Merchants can now accept and process USDC on Solana alongside 70+ other supported cryptocurrencies."

For merchants where settlement cost is the primary variable, Solana-based USDC is among the most efficient options available today. Finassets is betting that enough of its merchant base falls into that category to make the integration worthwhile, and the direction of the broader market suggests they are probably right.
