Request Network API Supported Chains and Currencies

Request Network supports payment destinations on 8 networks — 7 EVM chains and Tron. EVM and Tron are co-equal first-class networks for sign-in, payment destinations, payment links, and single payouts. The one current asymmetry: batch payments (incoming or outgoing) are EVM-only — the API rejects Tron batch requests.

Tron specifics

Tron

  • Mainnet only — no Tron testnet support
  • Native token: TRX (used for energy/bandwidth fees)
  • Stablecoins: USDT (TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t), USDC (TEkxiTehnzSmSe2XqrBj4w32RUN966rdz8)
  • Address format: Base58, prefix T
  • Wallets: TronLink, Guarda, Trust, WalletConnect-Tron
Tron wallet addresses are not interchangeable with EVM addresses. The API uses ERC-7828 humanReadableInteropAddress to disambiguate — Tron destinations resolve under the eip155:728126428 namespace.

​
ERC20 and Native Payments Supported Currencies

For ERC20 and native payments, Request Network exposes a broader catalog of 500+ tokens (the Request Network Token List). The destinations and secure payment flows above use the curated subset on the canonical 8 networks.
