Mercuryo

What is Mercuryo and what do they do?

Mercuryo is a crypto payment infrastructure provider founded in 2018, focused on enabling fiat-to-crypto and crypto-to-fiat conversion for web3 businesses. The company's core product is an on-ramp solution — a widget and API that lets web3 platforms accept card payments and convert them to crypto in seconds. Mercuryo positions itself as the payment engine behind web3 businesses, having processed over $2 billion in total volume and onboarded more than 12 million users globally.

The platform supports over 70 cryptocurrencies across leading Layer 1 and Layer 2 blockchains — including Ethereum, Bitcoin, Solana, TON, BNB Chain, Polygon, Arbitrum, and others. Fiat funding methods include credit and debit cards, Apple Pay, and other local payment options across 150+ countries.

Beyond on-ramp, Mercuryo offers Spend — a co-branded virtual card product that lets end users spend crypto directly from connected wallets — and Mercuryo Pay, a tool for managing crypto payments. Integration is available via iFrame, API, or SDK, with options for native embedding or Webview.

Who is it for?

Mercuryo's primary audience is web3 businesses that need to monetise or onboard users through fiat entry points. This includes crypto wallet providers, decentralised exchanges (DEXs), NFT platforms, GameFi products, yield platforms, and browser extension wallets. Clients include MetaMask, Trust Wallet, Ledger, 1inch, PancakeSwap, Bybit, and Tonkeeper.

It is also relevant for any fintech or platform that wants to offer its users a regulated, embedded path from fiat to crypto — without building the compliance infrastructure in-house.
