# Supported chains and tokens

> All blockchain networks and tokens supported by managed wallets, including testnet availability.

## Supported chains and tokens

Managed wallets support the following chains. Each chain has its own set of supported tokens and ERC-3009 availability (required for x402 payments).

## Supported chains

| Chain    | Chain ID | Tokens     | x402 (ERC-3009) | MPP | Testnet                   |
| -------- | -------- | ---------- | --------------- | --- | ------------------------- |
| Base     | 8453     | USDC       | ✓               | —   | Base Sepolia (84532)      |
| Ethereum | 1        | USDC, USDT | ✓               | —   | Sepolia (11155111)        |
| Optimism | 10       | USDC       | ✓               | —   | OP Sepolia (11155420)     |
| Arbitrum | 42161    | USDC       | ✓               | —   | Arbitrum Sepolia (421614) |
| Polygon  | 137      | USDC       | ✓               | —   | Polygon Amoy (80002)      |
| Tempo    | 4217     | USDC.e     | —               | ✓   | Tempo testnet             |

ERC-3009 support is required for x402 payments. All EVM chains listed support ERC-3009 via USDC (Circle's USDC implements ERC-3009).

Tempo uses its own payment protocol (MPP) — x402 is not supported on Tempo. MPP is not supported on any chain other than Tempo.

## Using the Chain enum

```typescript theme={null}
import { Chain, Token } from '@prudra/core';

// Provision on Base
await provisionWallet({
  chain:           Chain.BASE,
  supportedTokens: [Token.USDC],
});

// Provision on Tempo
await provisionWallet({
  chain:           Chain.TEMPO,
  supportedTokens: [Token.USDC_E],
});
```

## Testnet mode

In development, set `network: 'testnet'` when provisioning:

```typescript theme={null}
await provisionWallet({
  chain:           Chain.BASE,
  supportedTokens: [Token.USDC],
  network:         'testnet',   // uses Base Sepolia
});
```

With `PAYMENT_STUB_MODE=true`, testnet RPC is used and payments are simulated — no real tokens needed.

## Active chain limits

The number of active chains (chains with at least one wallet) is plan-limited:

| Plan       | Active chains |
| ---------- | ------------- |
| Hobby      | 1             |
| Pro        | 5             |
| Enterprise | Unlimited     |

A chain becomes "active" when you provision a wallet on it. Deprovisioning a wallet frees the chain slot.

## USDC.e on Tempo

USDC.e is the Tempo bridged version of USDC. It uses the same ERC-20 interface as USDC but on the Tempo network. For MPP payments, agents send USDC.e to the server wallet — the Prudra middleware verifies the Tempo transaction before proceeding.
