calcNextBlockBaseFee

A TypeScript project to calculate the next block base fee, typically used in blockchain or EVM-based systems.

Features

• ✅ TypeScript Support: Written in TypeScript
• ✅ Base Fee Calculation: Implements logic to calculate the next block base fee
• ✅ Configurable: Easily adaptable for different fee calculation rules
• ✅ Error Handling: Validates input and handles edge cases

Installation

npm install

Calculates the next block base fee based on the current base fee, gas used, and gas target.

Parameters:

• currentBaseFee: The base fee of the current block
• gasUsed: The amount of gas used in the current block
• gasTarget: The target gas for the block

Returns: The calculated base fee for the next block

Prerequisites

• Node.js (v14 or higher)
• npm

Setup

# Clone the repository
git clone <repository-url>
cd calcNextBlockBaseFee

# Install dependencies
npm install

# Build the project

Scripts

• npm run build: Compile TypeScript to JavaScript
• npm run test: Run tests
• npm run dev: Watch mode for development

Algorithm

The base fee calculation typically follows the EIP-1559 specification:

1. If gasUsed equals gasTarget, the base fee remains unchanged.
2. If gasUsed is higher than gasTarget, the base fee increases.
3. If gasUsed is lower than gasTarget, the base fee decreases.

Refer to EIP-1559 for the exact formula and logic.

Error Handling

The project validates input values and handles edge cases such as negative numbers and overflow.
