SolidState Solidity

SolidState is an upgradeable-first Solidity smart contract development library.

It consists of the following packages:

package description πŸ“•
@solidstate/abi contract ABIs πŸ“–
@solidstate/contracts core contracts πŸ“–
@solidstate/library functions for interacting with and validating contracts πŸ“–
@solidstate/spec portable tests which may be run against third-party implementations of core contracts πŸ“–

Note: A version of this library has been audited by Hacken. More details are available in the report.

Contracts

All contracts are designed to either be deployed through the standard constructor method, or referenced by a proxy. To this end, the diamond storage pattern is employed exclusively.

Spec

Where possible, automated tests are designed to be imported by repositories which make use of the SolidState contracts and run against any derived contracts. This is to help prevent unintended changes to to the base contract behavior.

For example, consider a custom ERC20Base implementation:

import '@solidstate/contracts/token/ERC20/base/ERC20Base.sol';

contract CustomToken is ERC20Base {
  // custom code...
}

Rather than rewrite the ERC20Base tests or assume that all core behavior remains untouched, one can import the included tests and run them against the custom implementation:

describe('CustomToken', function () {
  let instance;

  beforeEach(async function () {
    const factory = await ethers.getContractFactory('CustomToken');
    instance = await factory.deploy();
    await instance.deployed();
  });

  describeBehaviorOfERC20Base(
    {
      deploy: () => instance,
    },
    [],
  );

  // custom tests...
});

If parts of the base implementation are changed intentionally, tests can be selectively skipped:

describeBehaviorOfERC20Base(
  {
    deploy: () => instance,
  },
  ['#balanceOf'],
);

describe('#balanceOf', function () {
  // custom tests
});

Development

Install dependencies via Yarn:

yarn install

Setup Husky to format code on commit:

yarn prepare

Link local packages and install remaining dependencies via Lerna:

yarn run lerna bootstrap

Compile contracts via Hardhat:

yarn run hardhat compile

Automatically upgrade dependencies with yarn-up:

yarn upgrade-dependencies

Testing

Test contracts with Hardhat and generate gas report using hardhat-gas-reporter:

yarn run hardhat test

Generate a code coverage report using solidity-coverage:

yarn run hardhat coverage

Publication

Publish packages via Lerna:

yarn lerna-publish
