Stablecoin On/Off-Ramp APIs

Rain provides API infrastructure for converting between fiat currencies and stablecoins in both directions, enabling businesses to embed fiat-to-stablecoin and stablecoin-to-fiat conversion rails directly into their applications.

Fiat-to-Stablecoin (Money-in)

Rain's Money-in API converts local fiat currency into stablecoins instantly via virtual accounts. Designed for platforms that need to fund stablecoin wallets, card programs, or cross-border payment pipelines from traditional currency inputs. Key capabilities include instant local currency to stablecoin conversion, single API integration for payroll and AP systems, 24/7 disbursements, and support for all major and local currencies to USDC, USDT, and custom stablecoins.

Stablecoin-to-Fiat / Cross-Border Off-Ramp (Money-out)

Rain's Money-out API converts stablecoins to local currency and settles cross-border payments in real time. Supports global disbursements, contractor payouts, remittances, and platform-level spending conversion. Instant 24/7/365 settlement across Ethereum, Solana, and additional supported chains.

Underlying Infrastructure

Both products are built on Rain's modular, multi-chain stablecoin infrastructure platform — SOC 2 compliant, PCI certified, with embedded KYC/AML tooling. Rain is a Visa Principal Member that settles directly in USDC daily, including weekends and holidays, processing $3B+ annualised across 170+ countries and 200+ partners.
