Onramper is a fiat-to-crypto (and increasingly fiat-to-crypto + off-ramp) aggregation platform that allows wallets, exchanges, and dApps to embed a “Buy crypto” (and sometimes “Sell”) flow via a single widget or API. Instead of integrating many providers one-by-one, customers integrate Onramper once; Onramper routes end-users to an underlying on/off-ramp provider based on availability, pricing/quotes, payment methods, and region. The documentation describes it as a “fiat-to-crypto aggregator” and highlights multiple on-ramp providers in a single integration.
Primary buyers/users (B2B):
