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):
1.`address token` - address of ERC20 token for a new 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.
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.
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`.
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.
