This script extracts the ‘randao’ information from the Beacon chain block details in JavaScript using the Axios package.

6 Steps

This script uses web3.js to evaluate whether a specific block within a blockchain network has been integrated into the main chain or if it was a result of a reorg.

6 Steps

These web3.js and ethers.js scripts provide a straightforward way to generate encoded event signatures and parameters that can be utilized in the topics filter when pulling logs from an EVM-compatible chain.

7 Steps

These scripts show you how to encode callData parameters using the Ethereum ABI specification and web3.js to interact with smart contracts programmatically.

Hexadecimal strings are used to represent addresses and encode gas data and values. These scripts show you how to do it programmatically within your DApps.

4 Steps

This Recipe shows how to send batch requests to your Chainstack node instead of sending multiple loop-based requests. Adopting this approach can substantially boost the performance of your DApp.

7 Steps

This Recipe shows you how to efficiently send multiple requests to an Ethereum node instead of using a for loop by fetching an account balance for the past 500 blocks.

6 Steps

This Recipe shows you how to leverage subscriptions, WSS endpoints, and web3.js to monitor incoming transactions in real-time.
