EIP1559-sender

EIP1559-sender is a Go-based Ethereum transaction sending tool specifically designed to support the EIP-1559 gas fee mechanism.

Basic concepts

• maxFeePerGas >= (base Fee + priority Fee)
• gas Fee = min(base Fee + priority Fee, maxFeePerGas) * gas limit
• priority Fee = min(maxPriorityFeePerGas, maxFeePerGas - base Fee)

Features

• Utilizes the go-ethereum client library
• Implements EIP-1559's DynamicFeeTx transaction type
• Automatic estimation of gasLimit, baseFee, and maxPriorityFeePerGas
• Calculation of optimal maxFeePerGas

Dependencies

• go get github.com/ethereum/go-ethereum

Install

go install github.com/gmh5225/EIP1559-sender@v0.0.2
