# Supported Chains and Currencies

> Supported chains and currency coverage across Request Network API payment types

## 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.

## Supported networks

### Mainnet

| Network         | Chain ID    | Network ID     | USDC | USDT | Notes                                 |
| --------------- | ----------- | -------------- | ---- | ---- | ------------------------------------- |
| Ethereum        | `1`         | `mainnet`      | ✓    | ✓    |                                       |
| Arbitrum One    | `42161`     | `arbitrum-one` | ✓    | ✓    | USDT0 payment currency also available |
| Optimism        | `10`        | `optimism`     | ✓    | ✓    | USDT0 payment currency also available |
| Base            | `8453`      | `base`         | ✓    | ✓    |                                       |
| Polygon         | `137`       | `matic`        | ✓    | ✓    | USDT0 payment currency also available |
| BNB Smart Chain | `56`        | `bsc`          | ✓    | ✓    |                                       |
| **Tron**        | `728126428` | `tron`         | ✓    | ✓    | TRC-20 tokens, `T...` addresses       |

### Testnet

| Network | Chain ID   | Network ID | Tokens          |
| ------- | ---------- | ---------- | --------------- |
| Sepolia | `11155111` | `sepolia`  | FAU, USDC, USDT |

All token addresses above are mainnet contracts. Use them as the `tokenAddress` when creating a payment destination via the [Auth API](https://auth.request.network/open-api/#tag/payee-destination).

<Note>
  **USDT0** is supported as a payment currency (an alias of USDT) on **Arbitrum One**, **Optimism**, and **Polygon** — for example `USDT0-arbitrum-one`, `USDT0-optimism`, `USDT0-matic`. It is also part of the cross-chain currency set (USDC, USDT, USDT0). USDT0 is a payment/cross-chain currency, not a separate payee-destination token — receiving destinations are registered in USDC or USDT.
</Note>

## Feature support per chain

| Feature                                | EVM (7 chains) | Tron |
| -------------------------------------- | -------------- | ---- |
| Wallet sign-in (Dashboard)             | ✓              | ✓    |
| Payment destinations (ERC-7828)        | ✓              | ✓    |
| Single incoming payments               | ✓              | ✓    |
| **Batch incoming payments**            | ✓              | ✗    |
| Single outgoing payouts                | ✓              | ✓    |
| **Batch outgoing payouts**             | ✓              | ✗    |
| Conversion payments (fiat-denominated) | ✓              | ✓    |
| Cross-chain swap-to-pay (Li.Fi)        | ✓              | ✓    |
| Recurring payments                     | ✓              | ✓    |

<Warning>
  Batch payments (one transaction paying multiple recipients, or one signed batch payout) are supported on EVM only. Submitting a batch with Tron payees returns a 400 with: `Batch payments are not supported for TRON networks. Please submit individual payment requests.`
</Warning>

## Tron specifics

<Card title="Tron" icon="bolt">
  * **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
</Card>

<Info>
  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.
</Info>

## 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.

</Card>

<Info>
  The token list is a superset and may include tokens on chains outside the destination flow. For payment destinations and secure payment links, use the 8 networks listed above.
</Info>

## Conversion Payments Supported Currencies

* USD
* EUR
* CNY

## Currencies API Endpoints

The Currencies API lets you discover available currencies and conversion routes.

### Key Features

* **Payment request integration**: get currency IDs required for request creation
* **Payment integration**: retrieve token/network metadata for settlement logic
* **Currency validation**: verify supported currency IDs before creating requests
* **Multi-chain support**: discover tokens across supported chains

### Currency Object Fields

Typical fields include:

* `id` (for example `USDC-mainnet`)
* `name`
* `symbol`
* `decimals`
* `address`
* `network`
* `type`
* `chainId`
