Cronos (CRO) introduces the zkEVM Developers Portal, providing APIs to streamline decentralized app development on its zkEVM blockchain.





Cronos (CRO) has launched the Cronos zkEVM Developers Portal, a comprehensive resource aimed at accelerating the development of decentralized applications (dapps) on the Cronos zkEVM blockchain, according to Cronos Newsletter.

Developer API Access

The core feature of the new portal is the Developer API, which allows developers to query blockchain data, verify smart contracts, and build sophisticated applications seamlessly. The API supports GET/POST requests, providing access to a range of data types:

  • Accounts data: Balance, transaction history, internal transactions
  • Blocks data: Block details
  • Contracts data: ABI, source code, verification submissions, and status
  • ETH proxy: Proxy for commonly used zkEVM RPC endpoints
  • Logs data: Log details
  • Tokens data: Account balance for tokens, total supply for tokens
  • Transactions data: Transaction status

This real-time data, typically updated within minutes, enhances the performance and reliability of dapps.

Getting Started With the Cronos zkEVM Developer API

To utilize the Cronos zkEVM Developer API, developers need to register an account on the Account Registration page of the portal. After registration, users can access both mainnet and testnet API keys from their dashboard.

Comprehensive documentation is available to guide developers through making requests, parsing responses, and using various endpoints. The documentation covers a wide range of data, including accounts, blocks, contracts, transactions, logs, tokens, and statistics.

The API supports any programming language capable of making HTTP requests, offering flexibility in development environments, whether it’s JavaScript, Python, Java, or others. To ensure fair usage, the API enforces a rate limit of 50,000 calls per day, sufficient for application development but potentially restrictive for intensive production use.

With an API key and detailed documentation, developers are equipped to create innovative solutions on the Cronos zkEVM chain.
