Developer Platform Dashboard

Python

from crypto_com_developer_platform_client import Client

Client.init(
    api_key="YOUR_API_KEY",
    provider="https://your-provider.com"  # Optional
)

TypeScript / JavaScript

import { Client } from '@crypto.com/developer-platform-client';

Client.init({
  apiKey: 'YOUR_API_KEY',
  provider: 'https://your-provider-url.com', // Optional
});

Supported Chains

The SDK supports both Cronos EVM and Cronos ZK EVM networks.

Python

from crypto_com_developer_platform_client.interfaces.chain_interfaces import CronosEvm, CronosZkEvm

CronosEvm.MAINNET     # Chain ID: 25
CronosEvm.TESTNET     # Chain ID: 338
CronosZkEvm.MAINNET   # Chain ID: 388
CronosZkEvm.TESTNET   # Chain ID: 240

TypeScript / JavaScript

import { CronosEvm, CronosZkEvm } from '@crypto.com/developer-platform-client';

CronosEvm.Mainnet; // Chain ID: 25
CronosEvm.Testnet; // Chain ID: 338
CronosZkEvm.Mainnet; // Chain ID: 388
CronosZkEvm.Testnet; // Chain ID: 240
