Integrate MoneyGram Ramps on Solana

Embed the Ramps widget (iframe or React Native WebView). Your app creates sessions server-side; MoneyGram handles KYC, quoting, and cash settlement. You handle wallet UX and either user signing or hot-wallet transfers.

Legacy Stellar SEP (whitelist)? SEP-10 / SEP-24 guide. Stellar widget partners: Stellar hub.

Docs follow one map: Non-custodial quickstart and guide per host (Web, React Native). Custodial · both chains holds setup, cash-in, and cash-out. Host setup is Embed the widget. Full map.

1.Request sandbox keys or sign in to the partner portal if you are already onboarded.
2.Copy .env.example to .env.local and set MONEYGRAM_SK.
3.Run the command, connect a devnet wallet with USDC, and try the widget.
