The developers at Etherscan have launched the beta version of API v2, providing a unified interface for interacting with over 50 EVM-compatible blockchains, including popular networks like Ethereum, BNB Smart Chain, Polygon, Arbitrum, as well as testnets like Sepolia, Goerli, and others.

The goal of the update is to simplify the creation of multi-chain applications by providing a single access point for blockchain data. The new API offers a flexible and convenient way to manage information from various networks, allowing developers to use one API key and the chainID parameter to specify the desired chain. This resolves the issue of needing multiple keys and complex configurations for each network, optimizing the integration process and increasing the efficiency of applications.

API Keys and Security

API keys in Etherscan have also been updated to enhance security. They act as a digital ID badge, helping to identify users and confirming their access to data. This approach protects both data and users, preventing unauthorized actions and ensuring that only verified participants have access.

With the release of v2, Etherscan has made it easier for developers to access multi-chain data: now they can integrate data from multiple blockchains in a single query while maintaining backward compatibility with v1. This reduces the risk of failures in existing applications and services, allowing a smooth transition to the new version of the API.

Developer Convenience

For developers, using a single API key significantly simplifies the code and setup, speeding up product launches and reducing maintenance costs. Reducing overhead is especially important for developing dApps that support multiple blockchains, as it allows developers to focus on the functionality and user interface of the application rather than infrastructure details.

It’s worth noting that in June, Etherscan introduced the Code Reader tool powered by AI, designed to analyze the source code of smart contracts.
