Coverage model

Secure Payment Pages support the same 8 networks as Request API destinations: Stablecoins (USDC, USDT) are supported on every mainnet, including Tron (USDT and USDC, TRC-20). USDT0 is additionally available as a payment currency (an alias of USDT) on Arbitrum One, Optimism, and Polygon. FAU is available on Sepolia for testing. For a payer’s perspective, a Secure Payment link can be paid from any of these chains — when the source chain differs from the merchant’s destination chain, the swap is routed through Li.Fi (EVM source chains only; Tron payments are same-chain).
Batch secure payment links — multiple payees in a single hosted link — are EVM-only. Tron Secure Payment links are single-recipient.
For the canonical chain × currency table and feature-support matrix, see Supported Chains and Currencies.

Supported currencies

Currencies are determined by the Request token list and available per network. Use GET /v2/currencies to query support by network.

​
How to verify support

  • Query GET /v2/currencies with network and symbol filters for discovery
  • Validate currency IDs before calling POST /v2/secure-payments
  • Use the same network and currency validation rules you apply to normal request flows
For an at-a-glance list of ecosystem support, see Supported Chains and Currencies.

​
Preflight checklist

  • Confirm each currency ID exists in GET /v2/currencies
  • Confirm each request network is supported by your target flow
  • Confirm your selected currencies are available on those networks
