Protocol Playground•

Playground exploring solidity patterns, gas optimizations and compilations of notes.

Doing this for fun, but also to build a personal resource, and share it with others.

Notes

1. State Variable Notes
2. Gas benchmark of EIP1167 Clones vs. Clones with immutable Args
3. Basic Gas Optimizations
4. CREATE3 Factory (WIP)

Contracts

1. EIP1167 Clones
2. Clones with Immutable Args
3. ERC721 Merkle Drop
4. Minimal Multisig with EIP712
5. Utility Contract for Type Conversions (for solidity tests etc)
6. Generic User - Use in tests to execute virtually any operation as a user
7. Create3 Factory
