MevWallet TS

A Typescript Library for interacting with MevWallets

Please see the MevWallet repo for an explanation of what a MevWallet is, and why you'd want to use one

How do I use this repo?

This repo has a TS library for working with MevTxns, based on ethers.js.

Use MevTxBuilder to build a txn:

import { MevTxBuilder } from 'mev-tx-ts';
const builder = new MevTxBuilder(walletAddress, provider);
builder.to = wethAddress;
// this is the easiest way to do calls to other contracts :)
builder.data = weth
  .getInterface()
  .encodeFunctionData('transfer', recipient, amount);
builder.tip = ethers.utils.parseUnits('1', 'gwei');
await builder.complete();

let signed = await builder.sign(wallet);

Send the MevTx from some account:

builder.send(fromSigner, overrides);

You can also use this lib to deploy a new proxy contract:

import { getFactory } from 'mev-tx-ts';
const factory = getFactory(provider);
const wallet = factory.createWallet();

• MevWalletV1 Implementation: 0x0000000000c08718718B974D644B098C19bd0064
• MevWalletV1 ProxyFactory: 0x9248B5e672e1880af34068C0FaE18D30c26D05Fb

Didn't bother to grind an address for the proxy factory :)

Running Tests

Use devenv.sh from MevWallet and then run yarn test
