Finassets.io has added USDC (SOL) support to its Back Office, allowing eligible merchants to accept and process USDC on Solana alongside more than 70 other cryptocurrencies through the same payment button, checkout and API. The company says Solana has the second-largest share of circulating USDC after Ethereum, with roughly $6.7 billion of Circle's total supply on the network, and offers faster, lower-cost settlement than Ethereum, although fees can rise during congestion. Existing merchants can enable the option without a new integration, contract or separate dashboard. New customers can choose a no-code payment button or an API integration that generates a unique Solana wallet address and sends transaction details through webhooks. Finassets also offers Auto-Convert, which converts incoming crypto into a stablecoin when payment arrives and fixes the exchange rate at that time. USDC (SOL) uses the company's existing operational, security and compliance infrastructure, with deposits typically credited about 30 seconds after network confirmation. Support is available to eligible merchants in selected international markets, subject to programme terms, verification and applicable compliance requirements.
