Installation

To get started with the Arbitrum Gas Estimator, follow these simple installation steps:

1. Install the required Node.js packages:

   npm install
   Make sure to install the necessary dependencies:

bash Copy code npm install ethers @arbitrum/sdk Features

1. Signature Conversion Convert Bitcoin-like signatures to Ethereum format, making them compatible with Arbitrum transactions.

2. Address Recovery Recover Ethereum addresses from Bitcoin-like signatures and associated messages with ease.

3. Magic Hash Calculation Calculate a unique magic hash for a given data string using a specialized algorithm.

4. Advanced Gas Fee Estimation Estimate gas fees for Arbitrum transactions, considering various parameters to optimize cost efficiency.

Usage To harness the power of the Arbitrum Gas Estimator, import the necessary functions and call the gasEstimator function:

typescript Copy code import { gasEstimator } from './path/to/gasEstimator';

const txData = '0x...'; // Your transaction data const arbProvider = 'https://sepolia-rollup.arbitrum.io/rpc'; // Arbitrum RPC endpoint

gasEstimator(txData, arbProvider).then((estimatedFees) => { console.log('Estimated transaction fees:', estimatedFees.toString(), 'wei'); }); Functions Explore the diverse set of functions offered by the Arbitrum Gas Estimator:

• convertToEthSignature(bitSignature: string): string
• recoverEthAddress(bitSignature: string, message: string): string
• magicHash(data: string): string
• gasEstimator(txData: string, arbProvider?: string): Promise Examples typescript Copy code // Your example code here Contributing Your contributions are invaluable! Whether you have ideas, improvements, or bug fixes, we welcome your input. Feel free to open an issue or create a pull request.
