Aave Risk Steward

This repository contains some template/example code for executing cap updates on the RiskCapPlusSteward. There are 3 relevant contacts here:

• CapsPlusRiskStewardBase the abstract base contract handling the configuration snapshot creation and the forwarding to safe via ffi
• abstract Network contracts with all the relevant addresses initialized
  • CapsPlusRiskStewardMainnet
  • ... more to come
• MainnetExample the actual contract performing the update. The contract inherits the others and therefore handles testing and forwarding to safe automatically. The only thing that needs to be done is implementing:
  • name function returning a unique name (is used for generating the config snapshot and diffs)
  • capsUpdates function, analog to config engine

The code can be executed by running: forge script src/MainnetExample.s.sol:MainnetExample --rpc-url mainnet --sig "run(bool)" false -vv where the bool inside the run(bool) signature determines if the calldata should be sent to safe.

Development

This project uses Foundry. See the book for detailed instructions on how to install and use Foundry. The template ships with sensible default so you can use default foundry commands without resorting to MakeFile.

Setup

cp .env.example .env
forge install

Test

forge test

Advanced features

Diffing

For contracts upgrading implementations it's quite important to diff the implementation code to spot potential issues and ensure only the intended changes are included. Therefore the Makefile includes some commands to streamline the diffing process.

Download

You can download the current contract code of a deployed contract via make download chain=polygon address=0x00. This will download the contract source for specified address to src/etherscan/chain_address. This command works for all chains with a etherscan compatible block explorer.

Git diff

You can git-diff a downloaded contract against your src via make git-diff before=./etherscan/chain_address after=./src out=filename. This command will diff the two folders via git patience algorithm and write the output to diffs/filename.md.

Caveat: If the onchain implementation was verified using flatten, for generating the diff you need to flatten the new contract via forge flatten and supply the flattened file instead fo the whole ./src folder.
