SignerChange Event
This JavaScript script utilizes the Web3.js library to interact with a smart contract. It searches for events called 'SignerChange' within a range of specific validator identifiers. The script retrieves and displays information about changes in signatories ('SignerChange') for each validator in the specified range, providing the addresses of the old and new signatories for each event. This type of analysis is useful for tracking and auditing changes in signatories in a smart contract.

Dependencies Installation:
Ensure that Node.js is installed on your system. If not, you can download it from nodejs.org. Navigate to the directory where you saved the script on your system using the terminal or command prompt. Web3.js Installation:
Execute the following command to install the Web3.js library:
npm install web3Script Editing:
Open the script (your-script.js) in a text editor. Replace 'https://your-rpc-ethereum' with the RPC URL of your Ethereum node.
In the terminal or command prompt, within the directory where the script is located, execute the following command:
node your-script.jsMake sure to replace your-script.js with the actual name of your script file.
Note: that in the script, all events defined in the contract have been included, providing the flexibility to implement logic related to any specific event, not limited solely to SignerChange.
