Environments & Supported Chains

This page gives the API base URLs. It also gives the blockchain networks that GET /v1/wallet/networks returns (only active networks and active MYRC tokens). Always use that endpoint. Do not hard-code IDs.

API Environments

EnvironmentBase URL
Sandboxhttps://api.sandbox.blox.my
Productionhttps://api.blox.my

Hostnames: production https://api.blox.my, sandbox https://api.sandbox.blox.my. There is one merchant API. Wallet, Onramp, and Payout are all under /v1.

Quick health check

curl "https://api.sandbox.blox.my/v1/health" \
  -H "blox-api-key: $BLOX_API_KEY"
{
  "success": true,
  "message": "API key is valid",
  "account": {
    "id": "…",
    "name": "Your Business Name",
    "type": "BUSINESS",
    "status": "ACTIVE"
  }
}

Tip: Never commit production keys. Use a secret manager or CI/CD secrets.

Important Notes

  • MYRC on Ethereum, Arbitrum, and Base uses the ERC-20 interface. MYRC on Solana uses SPL.
  • The contract source is available on the explorers in the links above.
  • Do not use the same hard-coded tokenId values in different environments. Get them from the API.
