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

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:

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.
