[DRAFT] Add ERC20 Token Factory Precompile

Motivation 💡

This PR introduces the ERC20 token factory precompile, enabling the creation of x/erc20 STRv2 tokens directly from the EVM.

The precompile exposes two primary methods:

• Create Token:

function create(uint8 tokenType, bytes32 salt, string memory name, string memory symbol, uint8 decimals) external returns (address)

• Calculate Token Address:

function calculateAddress(uint8 tokenPairType, bytes32 salt) external view returns (address)

These methods allow for seamless integration and deterministic address calculation when deploying new ERC20 tokens.

Changes 🛠

• Added the precompile declaration in /app/precompiles.go
• Added the precompile implementation.

Considerations 🤔

• This PR depends on a change on evmos for including tokenType field in TokenPair type.

Dependencies 📦
