Project Overview 📄​

It is an application for a follow-up grant. The initial grant covered the first and second milestones:

This grant aims to cover milestones 3-5.


The mission of this project is to make ink! usable and facilitate WASM ecosystem adoption.

To be successful with this mission, we have outlined several steps that would need to be taken.

  1. OpenBrush is a library for secure smart contract development on ink!, same as OpenZeppelin on Ethereum.
  2. OpenBrush should serve as a starting point for every developer entering a Polkadot(ink!) ecosystem.
  3. In addition to having a standard implementation, Openbrush should also have macroses to simplify and abstract up applications(smart contracts) development.
  4. For Openbrush to fulfill its purpose, several changes must be made & several blockers to be overcome in ink! and in Substrate's pallet-contracts. We are committed to doing that in the context of this project.

This project is important to us as it's our strategic goal to accelerate Polkadot ecosystem development. Applications on Ink! are a considerable part of it.

Project Details​

OpenBrush should serve as a starting point for every smart contract developer coming from Ethereum. The extended documentation will cover several topics: the differences between ink! and Solidity, how developers should change their mindset, how to design their project, how to deploy contracts and test them, etc.

The library will provide the default implementation of standard contracts, which can be customized by developers. Also, the library will provide additional features useful for development that are not available in ink! yet(the plan is to integrate them to ink! itself at a later point within Openbrush scope), but which can be useful for development.

Our team aims to improve the smart-contract development experience, and wants to improve ink!, make it more user-friendly and to popularize it.

Ecosystem Fit​

  • Where and how does your project fit into the ecosystem?

The necessity of a solution like this seemed rather urgent to us when we started to work with ink!. We quickly realized that we strategically would like to become the company that builds in the ecosystem. We decided that we wanted to commit and help ink! become widely used. Right now usability of ink! can be easily improved. OpenBrush is dedicated to change that.

  • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

Our target audience is smart contract developers on ink!.

  • What need(s) does your project meet?

Our project is the starting point for smart contract developers coming from other ecosystems like Ethereum, and it aims to improve smart contract development on ink!.

  • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

We are only aware about one project metis. We partnered with them to collaborate on the ecosystem as we have the same common goal.

  • If so, how is your project different?

Our project isn't restricted to only providing the base implementation of contracts. Objectively speaking, based on what we know and what was listed in their proposal, here are key differences:

  • At the moment, OpenBrush is in far more advanced stage, Developer Experience of our library is significantly higher.
  • OpenBrush aims to propose and take care of standards for ink! (We've already created PSP for fungible tokens, and we plan to continue doing so)
  • OpenBrush aims to be a starting point for any smart contract developer by providing documentation.
  • Contribute to ink! and Substrate contract-pallet to improve the smart-contract development experience(add new features, fix bugs, etc.).

Vasyl Novak
Researcher BS in economics, MS in Quantitative Finance & Actuarial Science, experienced in, operations management, IB, financial and strategy consulting, including crypto, passed CFA II level

Lera Laricheva
Creative Designer
"In 2019 I started to get involved in the IT area. At first, I tried myself as a developer, and eventually I went away from that, to design. At first, I tried myself in design, then when I saw the result, and understood that I liked it, so I found courses and got a diploma. Then I tried freelancing, like many other beginners, but came to the conclusion that the working for a company is much better, and that is where a person can get a tremendous amount of experience, while constantly evolving, because you have to keep up with the tasks, and most importantly to understand them and try to implement them correctly. At the same time, it is my third year studying in Karazin, specialty marketing."

Development Roadmap 🔩​


We have decided to describe a full roadmap of an OpenBrush here, with estimates. However, the funding we request at this stage is for milestones 3-5.

  • Total Estimated Duration: 12.5 weeks(+ time for approving changes in ink! and PSP repositories)
  • Full-Time Equivalent (FTE): 2.5
  • Total Costs: 49,500 USD

Previous work​

Milestone 1 - Implement reusable basic contracts in ink!, similar to Openzeppelin​

  • Estimated duration: 2 weeks
  • FTE: 2.5
  • Costs: 10,000 USD (this cost is covered by Supercolony)
  • Delivery status: Delivered
0b.DocumentationWe will enhance inline documentation, and create a tutorial on how to import/customize contracts.
0c.Testing GuideWe will add unit tests to cover all basic logic and integration tests with Redspot, to verify that all works via contract-pallet
1a.Fungible token(Erc20)We will implement reusable Erc20 analog on ink!
1b.Non Fungible token(Erc721)We will implement reusable Erc721 analog on ink!
1b.Multi token(Erc1155)We will implement reusable Erc1155 analog on ink!
2a.AccessControlWe will implement reusable AccessControl analog on ink!
2b.OwnableWe will implement reusable Ownable analog on ink!

Milestone 2 - Simplify usage of library. Add a new features which extend ink!. Provide macroses that will allow creation of your own base implementation​

  • Estimated duration: 7 weeks
  • FTE: 2.5
  • Costs: 29,999 USD(covered by grant) + 5,000 USD which is covered by Supercolony
  • Delivery status: Delivered
0b.DocumentationWe will enhance inline documentation, update previous documentation based on simplifications, documentation for new features.
0c.Testing GuideWe will test macros, update tests according to new features, simplifications.
1.Remove boilerplate codeWe will provide a macro which will allow to remove boilerplate during usage of library(Library provides implementation on rust level in internal trait. User must reuse internal implementation with ink! messages. Our macro will simplify it). It will simplify the code structure and usage.
2.Derive for storagesWe will provide a derive macro to generate implementation for storage's structs. It will simplify integration of fields inside of struct and implementation of storage's traits for that fields.
3.Support default implementation in external traitsWe will add mnemonic support of default implementations inside of trait definition(traits defined via #[ink::trait_definition]). It is mnemonic, because under the hood we will generate internal trait with default implementation that will be used in external trait.
4.Support of modifiersWe will add support of modifiers, like in Solidity. User will be able to mark some function to use modifiers and it will simplify the code.
5.ReentrancyGuardWe will add implementation of ReentrancyGuard
6.Implement additional useful contractWe will implement PaymentSplitter, TimelockController and etc.

Current work - Scope of this Grant​

Milestone 3. Reduce the size of Erc20 contract​

  • Estimated Duration: 4 weeks
  • FTE: 1.5
  • Costs: 12,000 USD
0b.DocumentationWe will provide a report of how much each optimization reduced the size.
1.Reduce the size of Erc20 contractNow the most critical moment with ink! is the huge size of contracts. This issue described the problem very well. The parity team works in this direction, and we want to help with ink! side. The ink! team created issue 906, 916 and 910. We want to briefly(not full change, only minimal changes to reduce the size) implement them and provide a report(re-working data structure, reducing monomorphization, using dynamic dispatch in some cases). Based on this report, the ink! team can decide how better to implement them and which part is more critical. During the implementation, we will build examples with our version of ink! (also maybe we will modify some sub-crates). So the output of this work is a report and custom version of ink!. The code can be reused, or if ink! team agrees we can try to implement these issues by ourselves later as separate work.

Milestone 4. Pre-release - Standardization of tokens contracts. Implement extensions for contracts. Documentation​

  • Estimated Duration: 4.5 weeks(+ time for PSP approving)
  • FTE: 2.5
  • Costs: 22,500 USD
0b.DocumentationWe will provide inline documentation for macros, create a tutorial on how to use macros in your own project, with a detailed description of how it works inside.
0c.Testing GuideWe will add more tests to cover all macros, update tests according to new changes.
1.Create Proposal for Fungible tokenWe will create a proposal for standardization of Erc20 token in case of ink! and contract-pallet. Based on the final decision regarding the proposal update the implementation in library.
2.Implement extensions for tokensWe will implement extensions for Erc20, Erc721 and Erc1155 tokens.
3.Create Proposal for Non Fungible token and Multi tokenWe will create proposals for NFT and multi token, when proposal for FT token will be approved. Based on the decisions of these approves, we will update implementation in library.
4.Use original ink! instead of our ownWe will use ink! 3.0-rc6 version(or a new one if it will be compatible) instead of our own version of ink!.
5.Refactor the contracts to be compatible with PSPsWe will refactor the contracts according to the PSP.
6.Refactor the structure of the OpenBrush to provide agnostic traitsWe will refactor the structure of the OpenBrush to provide traits for each implementation of the contract without restriction and implementation related information:
- Traits will be defined in a separate module.
- The default implementation of that trait for a contract will be provided via unstable feature #![feature(min_specialization)].
- We will provide a new macro to generate a wrapper around a trait. That wrapper can be used for cross-contract calls. So the user is enough of the trait definition to do a cross contract call.

Milestone 5. Release - Contribution to ink​

  • Estimated Duration: 4 weeks(time depends on conversations in ink! repository)
  • FTE: 2
  • Costs: 15,000 USD
0b.DocumentationWe will provide inline documentation, example of usage of extensions.
0c.Testing GuideWe will add tests for extensions and for a new changes from ink! side.
1.Contribute to ink! with fixing of eventsWe will help to fix the issue with events.
2.Re-work the storage of contractsWe want to resolve the issue.
3.Refactor of implementation according changes in ink!After changes in ink! we will refactor the code of library.
