What is Mercuryo?

Mercuryo is a crypto payments infrastructure company founded in 2018. Its On-Ramp lets users buy cryptocurrency inside a wallet, exchange or Web3 app, while businesses connect the service through a widget, iFrame, SDK or API. Mercuryo says it supports 150+ countries, 70+ cryptocurrencies and more than 10 payment methods.

Company and team

Mercuryo is headquartered in London and also lists offices in New York, Limassol, Valencia and Vancouver. The company says its team has 300 employees and that more than 500 Web3 companies use its products. Its product range includes On-Ramp, Off-Ramp, cross-chain Swaps, fiat Pay-In and Pay-Out services, Mercuryo Pay, and Spend virtual cards developed with Mastercard.

How the on-ramp works

A partner embeds the purchase flow into its website or app rather than sending users to a separate exchange. The integration can use a widget, iFrame, SDK or API. Users create a Mercuryo account, complete identity verification, choose an asset, enter an amount and select a payment method before receiving the cryptocurrency in their wallet. Payment options include cards, Apple Pay, Google Pay, bank transfers and SEPA, along with other local methods.

The company advertises On-Ramp to Web3 in 15 seconds. Its broader infrastructure supports 30+ chains for Spend, while the On-Ramp page lists 70+ cryptocurrencies. Asset and network availability can vary by country and integration.

Fees and access

On-Ramp fees are dynamic. The amount depends on the payment method, user location and network fees, with the exact charge shown in the widget before confirmation. Mercuryo requires KYC and says it follows KYC and anti-money-laundering requirements.

Track record and risks

Mercuryo says it has processed $2 billion in total volume and onboarded 12 million people. As of October 2026, it reports 12M+ KYC-verified users, $15 million in revenue generated for partners and an average customer-care response time of 30 seconds. It launched Spend in 2024 and entered the United States in 2025. The company references ISO 27001 compliance.

The service depends on card networks, banks and other payment partners, so transactions can fail or reverse and may face regional restrictions. Country coverage and supported assets or payment methods vary, while the KYC process adds an identity and account-review dependency for users and integrating businesses.

Mercuryo combines broad geographic coverage with developer integrations, but dynamic fees and regional payment limits make transaction costs harder to compare.

Mercuryo is a fiat payment platform for wallets, exchanges, fintech apps and other Web3 products. Its On-Ramp supports 150+ countries, 10+ payment methods and 70+ cryptocurrencies.

Payment support covers cards, Apple Pay, Google Pay, bank transfers and SEPA. Businesses can add the service through a widget, iFrame, SDK or API, allowing checkout within an existing app. The company advertises crypto delivery in 15 seconds, while its customer-care page gives an average response time of 30 seconds. These figures address speed and support, but do not establish settlement times for every payment method.

Fees are dynamic and depend on the payment method and network fees. The exact charge appears in the widget before confirmation. Mercuryo requires identity verification and follows KYC and AML requirements.

  • Strengths include 150+ country coverage, 70+ supported cryptocurrencies and several integration formats.
  • Weaknesses include transaction-specific pricing and the absence of a single fee figure that applies across methods.
  • Regional support and network availability depend on the route selected.

Mercuryo has operated since 2018. It reports $2 billion in processed volume, 12 million people onboarded, 500+ Web3 companies using its services and a 300-person team. The company references ISO 27001 compliance.

In their own words

“Have passed over 50k usdt/c without a issue. Customer service response within 10-15 minutes. They even bridge with their partners (mercuryo.io) when I had a purchase issue. For a hot wallet I have no complaints after 2 years of experience.”

“New personal agents under the hood run on traditional payment companies, because it’s easy.

The interesting question is how we move agents from traditional payment rails to crypto-native ones without adding friction.”

If users can’t buy crypto in your app, they buy it somewhere else, and often stay there.

An on-ramp API keeps that moment in your product, with a provider handling payments and identity checks behind the scenes. We’ve broken down how it works: who owns each step, and how to get both engineering and business ready by launch day.
