ERC4337 Final Project

Instructions:

To begin using this project, run:

$ yarn install

You can also view more detailed instructions on starting this project under Stackup's readme. (Make sure to save the config.json file we have provided, however.)

If you would like to change the config file you can change:

1. ecoAddress: luke-goerli.eth the address the donations go to
2. offset: 0.001: change the fixed donation amount
3. roundTo: 0.001: change the rounding number

in config.json to customize these parameters.

You can also run any of these commands with --help, they have similar options.

Automatic Carbon Offset Wallet: ecoTransfer()

Transfer ETH and offset equivalent environmental cost

This function calculates the callGasLimit and maxFeePerGas for an ether transfer, and sends double the equivalent amount of ether to ecoAddress to offset the carbon cost of the transaction.

Example usage:

$ yarn run simpleAccount ecoTransfer --to 0xE188ae79149fb7441c854CbDb61ebb4be1a18a4e --amount 0.001

Automatic Donation Wallet: ecoTransferFixed()

Transfer ETH and fixed offset for environmental cost

This function transfersa a fixed amount offset of eth to ecoAddress in order to offset the environmental cost of the transactions or donate to an arbitrary on-chain cause (e.g. water rights).

Example usage:

$ yarn run simpleAccount ecoTransferFixed --to 0xE188ae79149fb7441c854CbDb61ebb4be1a18a4e --amount 0.001

Automatic Rounding Donation Wallet: roundTransfer()

Transfer ETH and send excess after rounding up to nearest 0.001"

This function automatically rounds each transaction the user sends to the nearest roundTo eth, and sends it to ecoAddress to offset environmental costs or send donations.

Example usage:

$ yarn run simpleAccount roundTransfer --to 0xE188ae79149fb7441c854CbDb61ebb4be1a18a4e --amount 0.0003
