Overview

MoneyGram currently supports on/off ramps for USD Coin (USDC) via the Stellar blockchain using the Stellar SEP-24 protocol. Wallets operating on different networks (e.g., Ethereum, Solana, Polygon), can still integrate with MoneyGram Ramps today by bridging USDC to Stellar through programmatic APIs.

Bridging USDC to Stellar: API Integration

To enable MoneyGram Ramps for wallets outside of the Stellar ecosystem, your application should:

1. Detect when a user holds USDC on a supported non-Stellar blockchain.
2. Programmatically bridge that USDC to Stellar using one of the third-party bridge APIs below.
3. Upon completion, use the MoneyGram Stellar SEP-24 API to initiate the cash-in or cash-out flow.
