PhotonPay has closed a $40 million Series C round led by Blockchain Capital to expand its stablecoin-focused Financial OS. SBI Group joined as a new investor, alongside existing backers IDG Capital, GL Ventures and Lightspeed Faction. The funding follows a January 2026 Series B round. PhotonPay reported $65 billion in annualized transaction volume as of August 2026, up from $30 billion reported at the time of its Series B. Its model combines stablecoin liquidity with bank relationships and local payment networks, rather than replacing those networks outright. The company says it holds 34 payment and financial licenses and regulatory authorizations and serves more than 200,000 corporate clients. It also plans an execution layer supporting the Model Context Protocol for autonomous AI agents. The expansion comes as Stripe and specialist firms including Rain and MassPay pursue corporate settlement opportunities.

Ramp partnered with Stripe and Bridge in July 2026 to deploy stablecoin rails for business bill payments and yield-bearing stablecoin accounts funded through standard fiat bank accounts. The arrangement shows how stablecoins can be incorporated into familiar payment workflows without requiring businesses to fund every transaction with digital assets. The economics depend on more than the cost of moving a token on-chain. Stripe charges merchants 1.5% for stablecoin checkout transactions, versus its standard card-processing fee of 2.9% plus $0.30; neither figure establishes the price of Ramp’s bill-payment service. Businesses receiving fiat may also face foreign-exchange and off-ramp costs, typically 0.3% to 2.0% when converting into local banking systems. Domestic clearing networks and compliance checks remain part of end-to-end delivery. Bridge’s issuance and transfer tools, alongside its conditional U.S. trust-bank approval, illustrate the infrastructure behind those payments—but not the elimination of every payment cost.

The European Payments Council has issued Version 1.1 of its Verification of Payee rulebook, effective September 20, 2026. The update addresses operational issues identified after launch, clarifies API specifications and refines the API Security Framework. It follows Eurozone deadlines requiring payment service providers to receive instant euro transfers from January 2025 and to send them and offer payee verification from October 2025. Under Regulation (EU) 2024/886, instant euro credit transfers must complete within 10 seconds and be available around the clock. Payee verification occurs before a transfer is executed, adding a separate real-time exchange to the payment process. Together, the requirements challenge legacy systems built around scheduled batch processing. Non-eurozone EU providers face receiving and sending deadlines in 2027, while national supervisors are collecting transaction, fee and decline metrics to monitor compliance.
