Onramper

Onramper is a fiat-to-crypto onramp aggregator based in Amsterdam, Netherlands. Founded in 2019 by Thijs Maas (CEO), Salah Abdelbaki (CTO), and Maurits Dewina (COO), the company was built to solve a problem the founders encountered while working on cross-chain interoperability tools: getting users from traditional bank accounts into crypto was unnecessarily difficult, fragmented, and failure-prone.

The core problem Onramper addresses is straightforward. A developer building a wallet, DeFi protocol, or NFT marketplace faces a choice: integrate with a single fiat onramp provider and accept its coverage gaps, KYC requirements, and authorization rates — or spend months integrating multiple providers to patch those gaps. Onramper collapses that tradeoff into a single SDK. Instead of choosing one onramp, developers connect to Onramper and gain simultaneous access to 30+ aggregated providers, including Moonpay, Stripe, Revolut, Ramp Network, Binance P2P, Koywe, and Coinify+, among others.

The Product Suite

Onramper offers four primary products. The flagship is its Onramp widget: a fiat-to-crypto purchase interface that can be embedded into any application with approximately eight lines of code and deployed in about one hour. The widget handles provider selection, payment processing, and KYC flows while presenting a consistent user experience regardless of which underlying provider fulfills the transaction.

The Offramp product provides the reverse flow — users converting crypto back to fiat — enabling wallets and exchanges to offer a full liquidity loop within a single integration. The Swap product adds cross-chain exchange functionality. Together, these three modules cover the primary entry, exit, and lateral movement needs of crypto users.

The Terminal is Onramper's analytics dashboard for integrators. It surfaces transaction history, conversion rates by provider, and behavioral data across the aggregated network, giving product teams visibility into where users are succeeding and where they are dropping off. For teams that need full UI control, Headless Ramps provides an SDK-first path: Onramper's routing and compliance logic runs underneath a fully custom interface built by the integrating company.

The Routing Engine

The mechanism that makes aggregation useful rather than merely additive is Onramper's smart routing engine. Rather than presenting users with a list of providers and leaving selection to them, the engine evaluates each transaction in real time against provider availability, fees, geographic coverage, and KYC load, then routes to the option most likely to succeed. This matters because authorization rates vary significantly by country, payment method, and transaction size. The optimal provider for a German user paying by SEPA differs materially from the best option for a Nigerian user on mobile.

The engine also handles KYC reuse. When a user has already completed identity verification with one provider in the network, that credential can be applied to subsequent transactions with compatible providers, reducing the friction that typically causes users to abandon purchases mid-flow.

Coverage and Scale

As of late 2025, Onramper's network spans 30+ onramp providers, 175+ payment methods, 1,500+ cryptocurrencies, and 190+ countries. Payment methods include credit and debit cards, bank transfers, SEPA, and a substantial catalog of regional options covering markets where card penetration is low, including India, Indonesia, Nigeria, and Latin America. Geographic reach into emerging markets has been a deliberate strategic focus: Onramper added Wello specifically to expand Nigerian coverage and integrated Koywe to address the Latin American market.

The business model avoids charging end users directly. Onramper earns referral commissions from its partner onramp providers based on transaction volume, aligning its incentive to route toward providers that complete transactions rather than merely initiate them.

Funding

In January 2022, Onramper raised a $6 million seed round led by EQT Ventures, with participation from Backed VC and TRGC. The capital was directed at product development and team growth.

Solana Ecosystem Presence

Onramper has established meaningful distribution within the Solana ecosystem through several high-profile integrations. Solflare, one of Solana's primary self-custody wallets, integrated Onramper's widget to power its fiat-to-SOL purchase flow; within one month of going live, Solflare's purchase volumes increased 280%. Jupiter, the dominant DEX aggregator on Solana, uses Onramper to provide fiat onramp functionality, enabling users to convert fiat directly into Solana assets through providers including Stripe, Banxa, and Topper. Axiom, a Solana-based trading platform backed by Y Combinator, announced a partnership with Onramper in December 2025 to give its users access to 130+ payment methods across 190 countries for funding SOL and BNB positions. Moonshot, a self-custody trading app built on Solana, integrated Onramper in April 2026 to expand payment method coverage to 180+ options for its traders.

Broader Integration Network

Beyond Solana, Onramper's technology is embedded across a wide cross-section of the crypto industry. Trust Wallet, serving 210+ million users, announced its Onramper integration in October 2025 to expand localized payment coverage in emerging markets, with the partnership targeting Indonesia, India, and Nigeria specifically. Coinbase Wallet, Exodus, ZenGo, Bitget Wallet, Gate.io, and Kraken (via Payward Ramp) also use the platform. MiniPay, Opera's stablecoin wallet, integrated Onramper in May 2025 to widen stablecoin accessibility, and Helio uses Onramper to support stablecoin payments for merchants globally.

Thijs Maas, Onramper's CEO, described the goal in the context of the Trust Wallet partnership: "Partnering with Trust Wallet brings us closer to that vision, combining our aggregator technology with one of the largest wallets in the world."

Company Status

Onramper is an active company. Its website resolves, documentation is maintained, and it continues to announce new provider integrations and wallet partnerships through mid-2026. The team is small — approximately 14 employees — but operates infrastructure that processes transactions on behalf of some of the largest wallets in the industry.
