What constants does the SDK export?

The SDK exports two convenience objects: USDC for contract addresses and CHAIN_ID for network identifiers. These cover the four chains Mandate supports. Use them instead of hardcoding addresses and chain IDs in your agent code.

​
USDC addresses

import { USDC } from '@mandate.md/sdk';

USDC.ETH_MAINNET  // 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48
USDC.ETH_SEPOLIA  // 0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238
USDC.BASE_MAINNET // 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
USDC.BASE_SEPOLIA // 0x036CbD53842c5426634e7929541eC2318f3dCF7e

Runtime keys and chain mapping

Your runtime key prefix determines which chains your agent can use.
Key prefixEnvironmentChains
mndt_test_*TestnetEthereum Sepolia, Base Sepolia
mndt_live_*ProductionEthereum Mainnet, Base Mainnet
Test keys only work with testnet chains. Live keys only work with mainnet chains. If you pass a testnet chain ID with a live key, the API returns a 422 error.
Use test keys during development. They connect to the same policy engine and return the same validation responses, but all transactions go to Sepolia testnets where tokens have no real value. 
import { MandateClient, USDC, CHAIN_ID } from '@mandate.md/sdk';

const client = new MandateClient({
  runtimeKey: process.env.MANDATE_RUNTIME_KEY!, // mndt_test_* for testnet
});

const result = await client.validate({
  action: 'transfer',
  amount: '5',
  to: '0xRecipientAddress',
  token: 'USDC',
  chain: String(CHAIN_ID.BASE_SEPOLIA),
  reason: 'Test payment for development',
});
