Uniramp

Uniramp is a universal fiat-to-crypto onramp and offramp aggregator built for web3 developers and their end users. Rather than routing every transaction through a single centralized payment processor, Uniramp connects simultaneously to a pool of both centralized ramp providers and decentralized DeFi protocols, then applies a smart routing algorithm to select the path that best balances cost, speed, and deliverability for each individual transaction. The result is a single integration point that unlocks global fiat access for any Solana dApp, wallet, or protocol without requiring teams to negotiate and maintain multiple provider relationships independently.

The Hybrid-Ramp Engine

The platform's core differentiator is its proprietary Hybrid-Ramp Engine, an orchestration layer that evaluates every transaction through three sequential steps. First it checks whether the desired conversion can be completed directly through one of the integrated centralized onramp or offramp providers. Second, it scans available DeFi routes via DEX aggregators and cross-chain bridge protocols to identify alternative paths. Third, the engine calculates the all-inclusive cost of each viable route—including spread and network fees, not just stated percentage fees—and selects the optimal combination based on the user's priorities.

This approach gives Uniramp access to a significantly wider set of liquidity than any single-provider integration can offer. Centralized providers in the network include Transak, Moonpay, Mercuryo, Coinify, Indacoin, UTORG, Unlimit, Xanpool, Transfi, Swapin, and Topper. Decentralized routes draw on protocols such as Uniswap, 0x, cBridge, Aave, Balancer, Apeswap, Bakeryswap, and Bancor, among others.

Integration Options

Developers can access the Hybrid-Ramp Engine through three delivery channels.

The embeddable widget is the primary integration path for most projects. The v2 widget, released in 2024, delivers a reported 30% speed improvement over the original version and added eight new provider integrations. It is fully customizable: operators can whitelist or blacklist specific cryptocurrencies, fiat currencies, and payment methods to match their product's regulatory posture or geographic focus. Widget themes can be adjusted to match brand styling. Fiat offramp functionality and crypto-to-crypto swap capabilities are flagged as forthcoming additions to the widget.

The API provides programmatic access to the same routing engine for teams that need tighter control over the user experience or want to build custom interfaces. A webhook system allows projects to receive real-time event notifications tied to transaction state changes, enabling downstream automation within their own backend infrastructure.

A hosted web application at uniramp.com also exposes the engine directly to end users who do not need a custom integration.

Coverage

Uniramp covers more than 90 countries, over 100 fiat currencies, and approximately 900 cryptocurrencies. Supported payment methods for onramp transactions include credit cards, Apple Pay, Google Pay, PayNow, SEPA bank transfers, and wire transfers. Solana is included among the supported blockchain networks, making SOL and Solana-native tokens accessible through the aggregator's routing engine.

Fees and KYC

Because Uniramp routes transactions through multiple underlying providers, fees vary by the partner selected for each transaction. Published provider fee ranges span from 0.49% to 5.49% (Transak) at the low end up to approximately 3.95% (Mercuryo) at the higher end, with Unlimit at 3.7%, Topper at 3.9%, Transfi between 1.5% and 3.5%, and Swapin between 0.8% and 1.35%. The engine accounts for spread and network fees in its route calculations, so the cheapest stated percentage rate does not necessarily produce the lowest all-in cost for a given transaction.

KYC verification is handled by the underlying provider selected for each transaction rather than by Uniramp itself. Providers use established identity verification services including Jumio, Sumsub, Veriff, and Onfido. Regulatory licensing coverage across the integrated provider set spans major jurisdictions including the UK (FCA), European Union (VASP, EMI), the United States (MSB), and others depending on the specific provider.

Solana Ecosystem Fit

Uniramp sits at the infrastructure layer of the Solana ecosystem, addressing one of the persistent friction points in onboarding new users: the gap between traditional finance and on-chain assets. Rather than competing with the protocols and applications that run on Solana, Uniramp is designed to be embedded within them. A DeFi protocol, NFT platform, or Solana wallet can integrate the widget or API to give users a native fiat-entry path without redirecting them to a third-party exchange.

The aggregator model is particularly relevant for projects targeting users in diverse geographies, since no single centralized provider offers consistent coverage and competitive rates across all markets. By routing dynamically across providers and DeFi alternatives, Uniramp can offer more consistent availability and pricing than a single-provider solution could.

Team and Background

The team behind Uniramp has not been prominently documented in publicly available sources. The project launched in 2023 and is classified as community-published on Solana Compass. No public security audit documentation was identified during research.
