# Reconstruction of `tornado-instances`
|
|
|
|
This is a (NOT-MINIMAL) reconstruction of the Tornado Cash `tornado-instances` repository with additional contract variants added. It is not minimal because some dependencies, because of the Github takedowns (and other stuff), had annoying build issues (at least for me) which made me inline a lot of the contract code.
|
|
|
|
Just like with `relayer-registry`, one annoying part of univ3 core code had to be edited to compile with `0.6.12`, meaning that you should execute `yarn build` before compiling the contracts.
|
|
|
|
There is currently NO tests for the contract variations or anything which the original authors did not write, due to the simplicity and the nature (non custodial) of the contracts, they can mostly be easily reviewed bar the cloneable versions of `ETHTornado` and `ERC20Tornado`.

# Tornado Pool Factory
|
|
|
|
## About
|
|
|
|
Separate instance of [Tornado classic](https://github.com/tornadocash/tornado-core) is needed for each [token, denomination] pair. This repository contains smart contracts of Tornado Pool Factory, which is used to create and register new pools:
|
|
|
|
- factory creates a new Tornado pool
|
|
- if there is [pool registry](https://github.com/Rezan-vm/tornado-relayer-registry/blob/main/contracts/tornado-proxy/InstanceRegistry.sol) on this chain (only ETH mainnet for now), the factory also creates [governance](https://github.com/tornadocash/tornado-governance) proposal for registration new pool in instance registry
|
|
|
|
There are two deployed contracts:
|
|
|
|
1. `InstanceFactory` - instance factory for the creation of new Tornado ERC20/native pools
|
|
2. `InstanceProposalCreator` - governance proposal factory for the addition of new Tornado instances to the Tornado instance registry
|
|
|
|
### InstanceFactory
|
|
|
|
Anyone for sidechains and only governance for mainnet can create a new instance by calling `createInstanceClone` method of the factory with parameters:
|
|
|
|
1. `address token` - address of ERC20 token for a new instance, zero address for the native currency
|
|
2. `uint256 denomination` - denomination for new instance (tokens can only be deposited in certain denominations into Tornado instances)
|
|
|
|
### InstanceProposalCreator
|
|
|
|
Anyone can create a governance proposal for the addition of a new instance by calling `createProposalApprove/createProposalPermit` method of the factory with parameters (proposal creation fee in TORN is charged from the sender):
|
|
|
|
1. `address token` - address of ERC20 token for a new instance, zero address for the native instance
|
|
2. `uint24 uniswapPoolSwappingFee` - fee value of Uniswap instance which will be used for `TORN/token` price determination. `3000` means 0.3% fee Uniswap pool. Zero value for the native instance.
|
|
3. `uint256[] denominations` - list of denominations for each new instance (tokens can only be deposited in certain denominations into instances).
|
|
4. `uint32[] protocolFees` - list of protocol fees for each new instance (this fee is only charged from registrated relayer during withdrawal process). `100` means 1% of instance denomination fee for withdrawal throw registrated relayer.
|
|
|
|
## Parameters
|
|
|
|
### InstanceProposalCreator
|
|
|
|
1. `max number of new instances in one proposal` - the current version supports the addition of a maximum of 4 instances at once.
|
|
2. `proposal creation fee` - this fee is charged from creator of the proposal during `createProposalApprove/createProposalPermit` factory method execution. It can be changed by governance. Default value is stored in `config.js`.
|
|
3. `TWAPSlotsMin` - minimum number of TWAP slots for Uniswap pool that is chosen during `createProposalApprove/createProposalPermit` factory method call. It can be changed by governance. The default value is stored in `config.js`.
|
|
|
|
## Warnings
|
|
|
|
1. This version of the factory creates a proposal for **immutable** Tornado instance initialization.
|
|
|
|
## Tests
|
|
|
|
Setting up the repository:
|
|
|
|
```bash
|
|
yarn
|
|
cp .env.example .env
|
|
```
|
|
|
|
Please fill out .env according to the template provided in it. Please ensure that all of the example values are set to the correct addresses.
|
|
|
|
To run test scripts:
|
|
|
|
```bash
|
|
yarn test
|
|
```
|
|
|
|
Test scripts cover instance factory deployment, proposal deployment, and executing proposal.
|
|
|
|
## Deploy
|
|
|
|
Check config.js for actual values.
|
|
|
|
With `salt` = `0x0000000000000000000000000000000000000000000000000000000047941987` address must be:
|
|
|
|
1. `SidechainInstanceFactory` - `0x3D36D4b204E68e8A1431ec31Bea1fFbA3eC04590`
|
|
2. `SidechainInstanceFactory proxy` - `0x9d5C91ccF5c58b312896C4B4De45426fA128b001`
|
|
3. `InstanceFactory` - `0x83216783423500116723884F70dB44fB7BBb855b`
|
|
4. `InstanceFactory proxy` - `0x300aF836C74c1Af73f4353130AC1314Ed59B6a0A`
|
|
5. `InstanceProposalCreator` - `0x2b73b3555F1904CB8042cA6703734438eD4F28a0`
|
|
6. `InstanceProposalCreator proxy` - `0x84E013c8699Cb115906929B68b1Dc5ca5B2Fc46c`
|
|
|
|
Check addresses with current config:
|
|
|
|
```shell
|
|
yarn compile
|
|
node -e 'require("./src/generateAddresses").generateWithLog()'
|
|
```
|
|
|
|
Deploy SidechainInstanceFactory:
|
|
|
|
Check config.js for the actual **admin** value for this sidechain (TornadoCash community multisig).
|
|
|
|
```shell
|
|
yarn hardhat run scripts/deploySidechainInstanceFactory.js --network mainnet
|
|
```
|
|
|
|
Deploy InstanceProposalCreator + InstanceFactory (ETH mainnet):
|
|
|
|
```shell
|
|
yarn hardhat run scripts/deployInstanceProposalCreator.js --network mainnet
|
|
```
|
|
|
|
Verify on Etherscan:
|
|
|
|
```
|
|
yarn hardhat verify --network <network-name> <contract-address> <constructor-arguments>
|
|
```
