## About
This repository contains governance proposal factory for the addition of new Tornado ERC20 instances to the Tornado router.
This repository contains:
1. `InstanceFactory` - instance factory for the creation new Tornado ERC20 pools
2. `InstanceFactoryWithRegistry` - governance proposal factory for the addition of new Tornado ERC20 instances to the Tornado router
### InstanceFactory
Anyone can create a new ERC20 instance by calling `createInstanceClone` method of the factory with parameters:
1. `address token` - address of ERC20 token for a new instance
2. `uint256 denomination` - denomination for new instance (tokens can only be deposited in certain denominations into instances)
### InstanceFactoryWithRegistry
Anyone can create governance proposal for the addition of a new ERC20 instance by calling `createProposalApprove/createProposalPermit` method of the factory with parameters (proposal creation fee in TORN is charged from sender):

## Factory parameters
### InstanceFactoryWithRegistry
1. `max number of new instances in one proposal` - the current version supports the addition of a maximum of 3 instances at once.
2. `proposal creation fee` - this fee is charged from creator of proposal during `createProposalApprove/createProposalPermit` factory method execution. It can be changed by governance. Default value is stored in `config.js`.
## Warnings
1. This version of the factory creates a proposal for **immutable** Tornado instance initialization.
2. Users should manually propose a proposal after its creation using the factory (in governance UI for example). As `propose()` method caller must have 1000 TORN locked in the governance. Moreover, the proposer can't propose more than one proposal simultaneously.
