This is a project I used to practice solidity development, which contains a lot of key techniques in solidity development.

If you are a newbie, you can clone this repository to learn.

If you find any bugs, feel free to pr.

Good luck, bro.

• Iterable mappable storage with O(1) complexity

• Using slots for reading and writing data

• Scalable Contracts (Transparent Agents)

• Offline authorization using signatures

• Implementing Whitelisting with Merkel Trees

• Using Multicall to Batch Execute Function Calls

• Based on uniswapV2, support any ERC20 Token to buy NFT.

• Supports staking ETH and returning platform coins as rewards

• ERC20, ERC721, EIP2612, EIP712

• Use foundry to build, test, debug and deploy Solidity smart contracts and use its cheat codes to manipulate the state of the blockchain to simulate various scenarios

• Use ether.js to link wallets, invoke contracts, and display logs. But the front-end part of the code is currently very imperfect😥

• Deploy sub graphs using the graph to allow developers to query contract event data.
