Aave proposals v3

This repository contains various proposals targeting the Aave governance. In addition to the actual proposals this repository also contains tooling to standardize certain protocol tasks. The tooling documentation is co-located with the relevant smart contracts.

Tooling

Config engine

The AaveV3ConfigEngine (Docs) is a helper smart contract to abstract good practices when doing "admin" interactions with the Aave v3 protocol, but built on top, without touching the core contracts.

A less comprehensive version of the engine also exists for protocol v2.

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
yarn

Create an aip

This repository includes a generator to help you bootstrap the required files for an AIP. To generate a proposal you need to run: yarn generate

To get a full list of available commands run yarn generate --help

yarn generate --help
yarn run v1.22.19
$ tsx generator/cli --help
Usage: proposal-generator [options]

CLI to generate aave proposals

Options:
  -V, --version              output the version number
  -f, --force                force creation (might overwrite existing files)
  -p, --pools <pools...>      (choices: "AaveV2Ethereum", "AaveV2EthereumAMM", "AaveV2Polygon", "AaveV2Avalanche",
                             "AaveV3Ethereum", "AaveV3Polygon", "AaveV3Avalanche", "AaveV3Optimism",
                             "AaveV3Arbitrum", "AaveV3Metis", "AaveV3Base")
  -t, --title <string>       aip title
  -a, --author <string>      author
  -d, --discussion <string>  forum link
  -s, --snapshot <string>    snapshot link
  -c, --configFile <string>  path to config file
  -h, --help                 display help for command

If you have any feedback regarding the generator (bugs, improvements, features), don't hesitate to create an issue. We'd <3 to see contributions.

Test

# You can use vanilla forge to customize your test
# https://book.getfoundry.sh/reference/forge/forge-test
forge test
# We also provide a script with sensible defaults to just test a single contract matching a filter
make test-contract filter=ENS

Deploy

The makefile contains some generic templates for proposal deployments. To deploy a contract you can run make deploy-ledger contract=pathToContract:Contract chain=chainAlias. The generator will inline exact instructions on the generated scripts.

Proposal creation

To create a proposal you have to do three things:

  1. deploy the payload & register it on the payloadsController
  2. create an aip
  3. create the mainnet proposal

While the first two steps can be performed in parallel, the final proposal creation relies on (1) and (2). Every step can in theory be performed by a different entity.

The address creating the mainnet proposal(3) requires 80k AAVE of proposition power.

1. Deploy payload

The payload is always deployed on the chain it affects. Therefore you need to adjust the relevant script accordingly. The generated scripts include exact instrauctions on what to execute.

2. Create an aip

The aip can be co-located with the proposal code as a markdown file. This repository will manage the upload to ipfs automatically once a pr is merged to main.

3. Create proposal

The proposal requires at least one payload and the encodedHash.

Troubleshooting Verification

If for whatever reason verification fails, there's a good chance the error is on the foundry side, not in our tooling. To retry a specific verification you can follow the following steps:

  1. copy verify.example.json to verify.json
  2. replace the chain with the appropriate chainId
  3. replace the hash with the transaction hash of the deployment transaction (make sure it's the deployment transaction, not the one registering the payload on the payloadscontroller)
  4. run FOUNDRY_PROFILE=<chainAlias> forge build --force
  5. run FOUNDRY_PROFILE=<chainAlias> npx catapulta-verify -b verify.json
