Angle Multisig

This repo contains scripts to push transaction to multisigs associated to Angle Protocol on Gnosis. More generally, signers of multisig can also use this repo to check that the transactions they see on the Gnosis Safe interface on the front correspond to what they expect.

Getting started

Install Foundry

If you don't have Foundry:

curl -L https://foundry.paradigm.xyz | bash

source /root/.zshrc
# or, if you're under bash: source /root/.bashrc

foundryup

To install the standard library:

forge install foundry-rs/forge-std

To update libraries:

forge update

Install packages

You can install all dependencies by running

yarn
forge i

Setup environment

Create a .env file from the template file .env.example. If you don't define URI and mnemonics, default mnemonic will be used with a brand new local hardhat node.

This repo can be used to interact with different Gnosis Safe. If so, you would need to have one specific .env file per safe.

Gnosis interactions

Add Delegate

The addDelegate.py file helps to add a delegate to a Gnosis Safe. A delegate is an address that can propose transactions to a Gnosis Safe, it does not have any on-chain right. The delegate address just has the right to mess up with the portal of waiting transactions associated to a safe. There are some other utility functions in this file.

The reason for introducing a delegate is that the address of the delegate can be unsafe and its private key can be stored in clear (because it never directly interacts with the blockchain). In the multisig, most addresses are going to be Ledger for which you do not want to store the private key, even on a GitHub repo.

Scripts: Propose and Verify

Create, Simulate and propose a Tx (Prefered way)

• Create a script in scripts/foundry. Take for example scripts/foundry/borrow/SetRateVaultManager.s.sol and the contract name is SetRateVaultManager
• Create the associate test in tests. If the script contract name is XXX the test contract should be named XXXTest.
• You may need to change in the scripts/submitFoundryTx.ts the safe on which you want to send the tx - Governor or Guardian
• You can create, simulate and potentially send (you will be asked if you want) the proposals by running yarn create-tx. You will be prompted to specify the script you want to run, you should enter XXX. Then asks on which chains you want to run the script, and finally after tests are passing you are asked if you want to send the proposal to the on chain governance.

Run all separetly (second way)

You can run a script with

yarn script:fork

which will generate an object in scripts/foundry/transaction.json with properties: chainId, data,operation,to,value. These are required to pass a transaction on Gnosis Safe.

Some scripts need to make on chain calls, so you should run beforehand:

yarn fork:{CHAIN_NAME}

Push a transaction to Gnosis

Simply run:

yarn submit:foundry

Make sure that your .env is correctly set for this and that you have the right values in scripts/foundry/transaction.json
