MoneyGram handles compliance, settlement and global cash infrastructure, so you can focus on building.
Wallets
Enable app users to access cash in 170+ countries and territories.
Exchanges

Developers
One simple API. Fast integration. Production-ready infrastructure built for scale.
Integration paths
Non-custodial or custodial, one widget SDK.
The Ramps widget SDK embeds in a web page or a React Native WebView. Pick the path that matches who holds the USDC, then start in sandbox: every new partner gets sandbox keys after registration, and KYB approval is required before production.
Non-custodial
Your users hold their own keys. The widget SDK runs the whole cash-in or cash-out flow; for cash-out it asks the user's wallet to sign the USDC transfer, and for cash-in the USDC arrives in the user's wallet. Available for web and React Native.
Custodial
You hold USDC for your users in an omnibus wallet. Your server opens each session for a customer. For cash-out it sends USDC to the deposit address; for cash-in it receives the USDC and credits the customer once the transfer is confirmed. The widget handles identity checks and the cash leg.
Full walkthroughs live in the Solana web integration guide and the developer documentation.
