Mercuryo

Mercuryo is a crypto payment infrastructure company founded in 2018, built to serve as the payment engine behind web3 applications. Rather than offering a consumer-facing exchange, Mercuryo operates primarily as a B2B layer: it embeds fiat-to-crypto and crypto-to-fiat conversion directly into wallets, exchanges, and decentralized applications through a white-label widget and API. More than 500 leading web3 companies use the platform, including MetaMask, Trust Wallet, Ledger, 1inch, PancakeSwap, Bybit, and Telegram Wallet.

Core Products

On-Ramp is Mercuryo's flagship offering. It allows end users to purchase cryptocurrency without leaving a partner application. The checkout flow accepts credit and debit cards, Apple Pay, Google Pay, bank transfers, and SEPA — and the company reports that new users can complete identity verification and their first purchase in under 15 seconds. As of mid-2026, Mercuryo has KYC'd more than 12 million users and processed over $2 billion in total volume, generating approximately $15 million in revenue-share for its partners.

Off-Ramp closes the loop by enabling users to convert crypto back to fiat and withdraw to local bank accounts or payment cards. This capability has become increasingly central to Mercuryo's value proposition as stablecoin usage has expanded. A January 2026 partnership with Visa Direct added near-real-time settlement to the off-ramp workflow, meaning users can receive fiat within minutes of initiating a conversion rather than waiting for standard bank transfer windows.

Spend provides virtual co-branded payment cards, issued instantly and backed by crypto balances held across supported chains. Users can spend against their on-chain assets anywhere card payments are accepted, with multi-chain support across more than 30 blockchains.

Mercuryo Pay rounds out the product suite as a crypto payment management solution for platforms that want to accept digital assets directly from customers.

Network and Asset Coverage

Mercuryo supports more than 70 cryptocurrencies and 14 major blockchain networks. Solana is included as a supported network for both on-ramp and off-ramp transactions, meaning SOL and Solana-based assets can be purchased directly through any partner app that embeds Mercuryo's widget. The platform covers 150 countries with 10-plus local payment methods, including currencies such as the Turkish lira, Brazilian real, Nigerian naira, and Mexican peso — reflecting a deliberate focus on markets where access to dollar-denominated assets through stablecoins is particularly valuable.

Stablecoin Trends and Market Position

Mercuryo's own transaction data illustrates the broader shift toward stablecoin utility. In the first half of 2026, stablecoins — primarily USDC and USDt — accounted for 57 percent of all off-ramp transactions processed through the platform, up from 25 percent a year earlier. Stablecoin off-ramp transaction volume grew 446 percent year-over-year during this period, compared to 38 percent for other cryptocurrencies. Stablecoins represented approximately 80 percent of the overall increase in Mercuryo's off-ramp activity.

The company attributes much of this growth to the rise of crypto payroll. Industry data cited by Mercuryo shows that 25 percent of businesses already pay some workers in crypto, with the majority of those withdrawals denominated in stablecoins. Weekend transaction volumes for stablecoins average 86 percent of weekday levels, a pattern that reflects users accessing liquidity outside traditional banking hours.

The overall on-ramp conversion rate — a key measure of how many users who initiate a purchase actually complete it — improved from 12 percent in the first half of 2025 to 21 percent in the first half of 2026, a 75 percent year-on-year increase. Mercuryo attributes this to UX simplification, including the February 2026 launch of native Apple Pay integration.

Compliance and Recognition

Mercuryo achieved ISO 27001 certification for information security management in April 2026, which the company markets as a benefit to enterprise partners who face their own compliance requirements. The platform operates under financial licenses across multiple jurisdictions and provides built-in KYC and AML screening as part of its embedded widget.

In December 2025, the company won "Best Crypto On-Ramp and Payments Solution" at the Cryptonomist Awards. It has appeared on the Sifted 100 Southern Europe leaderboard — a ranking of Europe's fastest-growing startups — for three consecutive years, reaching position 60 in 2026 up from 79 in 2025. Mercuryo received Great Place to Work certification across Cyprus, Spain, the United Kingdom, Croatia, and Serbia in mid-2026.

Integrations and Partnerships

Beyond its core wallet and exchange integrations, Mercuryo expanded into exchange infrastructure through a December 2025 deal with BitMEX, allowing BitMEX traders to buy crypto for spot and futures markets directly with fiat. The Telegram Wallet integration extends Mercuryo's on-ramp to Telegram's messaging-native crypto experience, reaching a mass-market audience through an interface most users already have installed. A 2025 Ledger and Mastercard partnership was cited by the company as a milestone in its push toward mainstream consumer finance.

Mercuryo is also available as a module in the Solana App Kit, the official toolkit for building Solana mobile applications, making it straightforward for Solana-native developers to embed fiat-to-crypto and crypto-to-fiat capabilities into their products without building payment infrastructure from scratch.

Summary

Mercuryo functions as a hidden but load-bearing layer of the web3 economy. Its APIs and widgets handle the friction points — identity verification, payment method integration, regulatory compliance, and currency conversion — that would otherwise prevent mainstream users from entering or exiting crypto ecosystems. For Solana specifically, the platform's support for SOL and its presence in the Solana App Kit means that wallet and DApp developers can add production-ready fiat rails without building or licensing those capabilities independently.
