# Tornado.Cash Governance [](https://github.com/tornadocash/tornado-governance/actions) [](https://www.npmjs.com/package/tornado-governance)
|
||||
# tornado-governance
|
||||
|
||||
Usage:
|
||||
## Description
|
||||
This repository holds all the tornado.cash governance upgrade and original governance contracts.
|
||||
The highest governance version right now is version 2, which includes a gas and vault upgrade.
|
||||
|
||||
```
|
||||
## Setup
|
||||
|
||||
```bash
|
||||
git clone https://github.com/tornadocash/tornado-governance.git
|
||||
yarn
|
||||
cp .env.example .env
|
||||
cp .env.example .env # you must enter your details into .env
|
||||
yarn test
|
||||
```
|
||||
|
||||
## How to upgrade implementation
|
||||
|
||||
1. Make sure once you deploy new Governance implementation, call `initialize` methods right after it.

# Tornado Governance Changes Documentation
|
||||
|
||||
`LotteryAndVaultProposal.sol`, if executed, modifies the tornado.cash governance contract in multiple ways.
|
||||
|
||||
This serves as documentation for all functions which are being added or modified and which have relevant functionality:
|
||||
|
||||
## Governance (Governance.sol)
|
||||
|
||||
The `Governance` contract available in the `tornado-governance` repository modifies the original Governance source code to enable overriding functions via inheritance. This has been submitted via PR.
|
||||
|
||||
This is a non issue, as logic and memory slots are left unaffected and properly referenced to. `tornado-governance` is being imported as a package.
|
||||
|
||||
## Governance Vault Upgrade (GovernanceVaultUpgrade.sol)
|
||||
|
||||
`GovernanceVaultUpgrade` is the first major upgrade to tornado governance. This upgrade introduces new logic which is used to communicate with `TornVault` from the governance contract. The motivation behind this upgrade:
|
||||
|
||||
- split DAO member locked TORN from vesting locked TORN.
|
||||
- block Governance from being able to interact with user TORN.
|
||||
|
||||
To solve point 1 of the formerly stated problems, and to reduce the logic bloat of the lock and unlock functionalities, we have opted for calculating the amount of user TORN locked in the governance contract. The calculations and explanations may be found [here](https://github.com/h-ivor/tornado-lottery-period/blob/final_with_auction/scripts/balance_estimation.md).
|
||||
|
||||
### Additions and changes
|
||||
|
||||
| Function/variable signature | is addition or change? | describe significance |
|
||||
| ---------------------------------- | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| `_transferTokens(address,uint256)` | change | instead of transferring to the governance contract, funds are now transferred to the torn vault with a `transferFrom` call, this has an effect on both the `lock` and `lockWithApproval` function |
|
||||
| `unlock(uint256)` | change | unlock now triggers `withdrawTorn(address,uint256)` within the vault which reverts on an unsuccessful transfer (safeTransfer) |
|
||||
| `version` | addition | tells current version of governance contract |
|
||||
| `address immutable userVault` | addition | address of the deployed vault |
|
||||
|
||||
### Tornado Vault (TornadoVault.sol)
|
||||
|
||||
The compliment to the above upgrade. Stores user TORN, does not keep records of it. Serves exclusively for deposits and withdrawals. Works in effect as personal store of TORN for a user with the balance being user for voting. Locking mechanisms are still in effect.
|
||||
|
||||
| Function/variable signature | describe significance |
|
||||
| ------------------------------- | --------------------------------------------------- |
|
||||
| `withdrawTorn(address,uint256)` | used for withdrawing TORN balance to users' account |

# Auctioning some Tornado for compensations ETH
|
||||
|
||||
To boost voting activity, one of our ideas is to compensate gas used for voting on proposals.
|
||||
Both for the castVote and castDelegatedVote functionality.
|
||||
|
||||
To make this as smooth as possible, we will compensate users directly in **ETH** (non-wrapped) for voting.
|
||||
The priority fee is not compensated for, as to make exploiting the compensations unnecessary and unprofitable.
|
||||
|
||||
In order to receive ETH, TORN will be auctioned off by the governance contract with the help of a auction helper
|
||||
(see contracts/auction/TornadoAuctionHandler.sol).
|
||||
|
||||
This contract has two functionalities:
|
||||
|
||||
- Initiate an auction.
|
||||
|
||||
- Convert all WETH it holds into ETH and send to Governance (callable by anyone).
|
||||
|
||||
This way, Governance does not need to handle WETH swap logic (would require extra logic) and ETH will be directly sent to the governance contract.
|
||||
|
||||
The initializeAuction function takes a couple of parameters:
|
||||
|
||||
```
|
||||
function initializeAuction(
|
||||
uint256 _auctionEndDate,
|
||||
uint96 _auctionedSellAmount,
|
||||
uint96 _minBuyAmount,
|
||||
uint256 _minBidPerOrder,
|
||||
uint256 _minFundingThreshold
|
||||
) external onlyGovernance {
|
||||
```
|
||||
|
||||
- \_auctionEndDate -> the auction end date expressed in UNIX format.
|
||||
- \_auctionedSellAmount -> the amount of TORN to be sold in the auction.
|
||||
- \_minBuyAmount -> this variable helps to define the minimum price via the following formula: \_auctionedSellAmount/\_minBuyAmount, in other words the minimum amount of TORN per ETH.
|
||||
- \_minBidPerOrder -> minimum buy amount per a single order (of tokens being auctioned), is also used to prevent users from buying too low amounts and hurting themselves.
|
||||
- \_minFundingThreshold -> minimum amount of buy tokens (ETH) for the ENTIRE auction. If this is not reached, the auction reverts and all tokens are sent back to their original owners.
|
||||
|
||||
This function does not take all the parameters for initializing the auction, the entire function may be seen below, some were left out of convenience:
|
||||
|
||||
```
|
||||
IEasyAuction(EasyAuctionAddress).initiateAuction(
|
||||
IERC20(TornTokenAddress),
|
||||
IERC20(WETHAddress),
|
||||
0, // orderCancellationEndDate
|
||||
_auctionEndDate,
|
||||
_auctionedSellAmount,
|
||||
_minBuyAmount,
|
||||
_minBidPerOrder,
|
||||
_minFundingThreshold,
|
||||
true, // isAtomicClosureAllowed
|
||||
address(0x0000000000000000000000000000000000000000), // access
|
||||
new bytes(0) // access
|
||||
);
|
||||
```
|
||||
|
||||
- Addresses of the tokens being bought/sold (ETH/TORN).
|
||||
- orderCancellationEndDate -> date until order can be cancelled. For us, this is 0, meaning orders can't be cancelled once set.
|
||||
- isAtomicClosureAllowed -> when auction end date is reached, a participant may set a last order in exchange for closing the auction, meaning it incentivizes the user to end the auction (gas payments, time saving) by giving him a risk-free action at the end. For us, false, due to tests showing that dust collection might not work if this is used.
|
||||
- Last two fields are for access management, we have no whitelist for the auction, thus redundant and set to 0 for us.
