Permissionless EthMultiVault Proxy

Overview

This repository contains a forked and modified version of the Intuition Attestor Contracts, redesigned to serve as a permissionless proxy for batch operations with EthMultiVault. The main purpose of this contract is to provide efficient batch deposit and redeem functionality for any user interacting with the EthMultiVault.

Key Features

• Permissionless Access: Anyone can use the proxy contract to interact with EthMultiVault
• Batch Operations: Efficient handling of multiple deposits and redemptions in a single transaction
• Gas Optimization: Reduced transaction costs through batched operations
• Direct User Ownership: All operations maintain direct ownership of assets by the end user

For detailed information about the modifications and architectural changes, see our Action Plan.

Deployments

The contract is currently deployed on Base Sepolia at: 0x60d7753825673a9d1942a117bfa63f7d9e16dcc4

Building and Running Tests

To build the project and run tests, follow these steps:

Prerequisites

• Node.js
• Foundry

Step by Step Guide

Install Dependencies

$ npm i
$ forge install

Build

$ forge build

Run Tests

$ forge test -vvv

Run Fuzz Tests

• Make sure you have at least node 16 and python 3.6 installed on your local machine
• Add your FUZZ_AP_KEY to the .env file locally
• Run the following command to install the diligence-fuzzing package:

$ pip3 install diligence-fuzzing

• After the installation is completed, run the fuzzing CLI:

$ fuzz forge test

• Finally, check your Diligence Fuzzing dashboard to see the results of the fuzzing tests

Run Slither (Static Analysis)

• Install the slither-analyzer package:

  $ pip3 install slither-analyzer

• After the installation is completed, run the slither analysis bash script:

  $ npm run slither

Deployment Process

To deploy the smart contracts on to a public testnet or mainnet, you'll need the following:

• RPC URL of the network that you're trying to deploy to (as for us, we're targeting Base Sepolia testnet as our target chain for the testnet deployments)
• Export PRIVATE_KEY of a deployer account in the terminal, and fund it with some test ETH to be able to cover the gas fees for the smart contract deployments
• For Base Sepolia, there is a reliable testnet faucet deployed by Alchemy
• Deploy smart contracts using the following command:

$ forge script script/Deploy.s.sol --broadcast --rpc-url <your_rpc_url> --private-key $PRIVATE_KEY

Deployment Verification

To verify the deployed smart contracts on Etherscan, you'll need to export your Etherscan API key as ETHERSCAN_API_KEY in the terminal, and then run the following command:

$ forge verify-contract <0x_contract_address> ContractName --watch --chain-id <chain_id>

Notes:

• When verifying your smart contracts, you can use an optional parameter --constructor-args to pass the constructor arguments of the smart contract in the ABI-encoded format
• The chain ID for Base Sepolia is 84532, whereas the chain ID for Base Mainnet is 8453
