Modern Treasury Launches Unified API for Fiat and Stablecoins
Modern Treasury has launched an integrated payment service provider (PSP) that supports both fiat and stablecoin transactions through a single API. The service allows companies to embed traditional and crypto payments into their products. The platform is designed to let users programmatically manage settlement, reconciliation, and compliance across both payment rails.
- The new service supports ACH, wire, RTP/FedNow, and push-to-card payments alongside stablecoins like USDC, USDP, and USDG, with USDT support coming soon. This integrated infrastructure is built on the same system that has already processed over $400 billion for companies such as Anchorage Digital, Gusto, and Navan. - To bolster its stablecoin capabilities, Modern Treasury acquired Beam, a fiat and stablecoin payment platform, in October 2025. The company has also partnered with Paxos for regulated stablecoin integration and is a member of the Circle Alliance Program and the Global Dollar Network. - The unified API is designed to significantly reduce market entry timelines for new financial products, allowing companies to launch in days instead of the typical 6-12 months required for direct bank onboarding. The platform also handles compliance complexities by performing KYC/KYB checks on end-users. - Modern Treasury was founded in 2018 by Dimitri Dadiomov, Matt Marcus, and Sam Aarons, who previously worked together at LendingHome (now Kiavi), where they built the initial payment operations platform that inspired the company. The company is backed by prominent investors including Benchmark, Altimeter, Salesforce Ventures, and Y Combinator. - The platform aims to solve significant operational challenges for finance teams, such as the manual reconciliation of crypto transactions with traditional accounting systems, which often involves fragmented toolsets for monitoring on-chain and fiat transactions separately. - A key feature is the "scale forever" model, which allows a company to start with Modern Treasury's PSP and later add direct bank partnerships while using the same API integration, providing a scalable path as the business grows. - Competitors in the broader crypto payment gateway space include companies like BitPay, CoinGate, and Stripe, which has also moved to support USDC payments. However, Modern Treasury's focus is on providing a unified back-end infrastructure for both payment types rather than solely a merchant-facing gateway.
