The library consists of modules and utilities that are built with a help of Openzeppelin Contracts (4.9.5) and go far beyond mediocre solidity.

• Implementation of Contracts Registry pattern
• Versatile access control smart contracts (Merkle whitelists, RBAC)
• Enhanced and simplified Diamond pattern
• Advanced data structures (Vector, PriorityQueue)
• ZK-friendly Sparse Merkle Tree and Incremental Merkle Tree implementations
• Flexible finance primitives (Staking, Vesting)
• Robust UniswapV2 and UniswapV3 oracles
• Utilities to ease work with ERC20 decimals, arrays, sets and ZK proofs

$ npm install @solarity/solidity-lib

The latest stable version is always in the master branch.

Check out the project's documentation with broad explanations and usage examples of every module. Full natspec guides are also available in the source code.

You will find the smart contracts in the /contracts directory. Feel free to play around and check the project's structure.

Once the npm package is installed, one can use the library just like that:

pragma solidity ^0.8.4;

import {OwnableContractsRegistry} from "@solarity/solidity-lib/contracts-registry/presets/OwnableContractsRegistry.sol";

contract ContractsRegistry is OwnableContractsRegistry {
    . . .
}

We are open to any mind-blowing ideas! Please take a look at our contribution guidelines to get involved.
