bounty: Project Galaxy Core Contract Gas Optimizations

[oyyblin]

Background

At Project Galaxy, we are building the infrastructure to power an open and collaborative credential data network. We help Web3 developers leverage credential data to build better products and communities. At the same time, data curators contribute to our credential data network while earning income once the data is utilized. You can learn more about Project Galaxy at our website and this deep dive article.

Task

We are looking for experienced developers to improve our core smart contracts and help us reduce the gas used when the contracts are invoked.

Contract repo: https://github.com/ProjectGalaxyHQ/galaxy-contracts

Contract technical specifications: https://github.com/ProjectGalaxyHQ/galaxy-contracts/blob/main/SPECIFICATION.md

Feel free to ask any questions on our Discord #developer channel.

Scope

• SpaceStationV2: https://github.com/ProjectGalaxyHQ/galaxy-contracts/blob/main/contracts/SpaceStation/SpaceStationV2.sol
• StarNFTV3: https://github.com/ProjectGalaxyHQ/galaxy-contracts/blob/main/contracts/StarNFT/StarNFTV3.sol

Rules

Please submit a PR including stats on gas before and after modifications in various invoke path. Please make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Bounty can be marked as complete once the PR is approved and merged.

• NFT must follow EIP712 standard
• NFT must implement IStarNFT interface
• NFT must be auto recognizable by Opensea
• SpaceStation must implement ISpaceStation interface
• Claim one NFT without fee gas must be lower then 150k gas on Rinkeby
• Events must not be removed

Am a smart contract developer with good experience with NFT, gone through the repo and i have a good solution for gas optimisation , will love to solve this for you ASAP
2) thenuelgeek has applied to start work (Funders only: approve worker | reject worker).

With a good knowledge of the EVM i will be able to optimise the existing contracts and make sure it meets the requirement
3) meysambazoo has applied to start work (Funders only: approve worker | reject worker).

Very good project 🚀🚀🚀
Love galaxy.eco
4) timton909 has applied to start work (Funders only: approve worker | reject worker).

your project has been more than interesting to me for a long time. i will try to find a suitable solution for you. there are many thoughts and ideas

That's very good project
6) masterkenshin has applied to start work (Funders only: approve worker | reject worker).

I love is a project very and very goods.
7) atarpara has applied to start work (Funders only: approve worker | reject worker).

I started the work on it. I already optimize the StarNFTV3 contract.
8) stopalov12 has applied to start work (Funders only: approve worker | reject worker).

Hello there! I have some ideas for gas optimisation of your smart contracts. I will be glad to assist you!

10) bshevchenko has applied to start work (Funders only: approve worker | reject worker).

Ready to start with this one 🙏💜
11) codelarkin has been approved to start work.

I have extensive experience gas-optimizing Solidity code. It would of course be way easier if you provide an existing truffle/hardhat test harness, but that is not necessary.

My credentials: developer for @FantomonFTM, @CultNFTs, @FarmgodDAO
12) timofeli has been approved to start work.

Will find an elegant way to optimize gas transactions so they are smaller
13) acevikings has been approved to start work.

I am an experienced solidity dev and I've checked out the contracts in scope and identified few optimisation avenues, I'll work on reducing the gas for contract deployment and function call to best possible.
14) 0xwil has been approved to start work.

ERC721RA is an improved implementation of ERC721A with refundability and 🔥 gas saving. It gives NFT minters freedom to return the NFTs and get refund.
