Core Capabilities
-
On‑Ramp: Fast fiat‑to‑crypto onboarding that claims a 15‑second flow for users. This product is designed to increase conversion and retention with minimal friction, offering KYC handling and a ready integration path for wallets, exchanges, and apps.

Spend (Co‑branded Cards): Virtual co‑branded cards that let users spend crypto from a connected wallet. Instant card issuance, multi‑chain support (40+ chains listed for Spend), and seamless wallet linkage make it suitable for consumer fintech apps and Web3 services that want to provide direct purchasing power from crypto balances.

Off‑Ramp & Pro: Tools to enable users to cash out from crypto to Visa and MasterCard, with specialized offerings for high‑volume business flows. Pro features target large deposits and withdrawals, liquidity management, and smoother settlement for enterprise clients.
-
Auxiliary Products (DCA & NFT Checkout): Dollar‑Cost Averaging (DCA) capabilities let users automate recurring crypto purchases, while NFT Checkout offers a click‑to‑purchase flow designed for rapid NFT sales and improved conversion on marketplaces.
-
Developer Tools & Integrations: iFrame, API, and SDK options enable native or embedded integrations (Webview), making Mercuryo adaptable to different product architectures. The platform also promotes an ecosystem program for developer support and partnership.

Getting started
To evaluate Mercuryo, teams typically review integration options (API vs iFrame vs SDK), confirm required compliance and regional payment methods, and pilot a single product (for example, On‑Ramp or Spend) to measure conversion and UX impact. For builders, the ecosystem program and documentation provide developer support to accelerate proof‑of‑concepts and production rollouts.
