[GENERAL] Please specify how many months you expect your project to last (from 2-12 months)

[GENERAL] Please indicate if your proposal has been auto-translated into English from another language.

[GENERAL] Does your project have any dependencies on other organizations, technical or otherwise?

[GENERAL] If YES, please describe what the dependency is and why you believe it is essential for your project’s delivery. If NO, please write “No dependencies.” in this field.

No dependencies

[GENERAL] Will your project outputs be fully Open Source?

[GENERAL] If NO, please describe which outputs are not going to be open source. If YES, please write “Project will be fully open source.” in this field.

Partially. The Wrapped Smart Contract system, as well as modifications to the EVM are public, but some parts of Milkomeda are not

[METADATA] SDG rating

Sidechains have always been part of Cardano’s scaling model, with some sidechains already existing like Milkomeda (EVM sidechain) and more planned. Additionally, L2s are increasing in popularity in other ecosystems and Cardano as well through Paima, which also help scale and add flexibility to the ecosystem.

However, it’s hard to get adoption for new sidechains or L2s if users have to download a new specific wallet for every sidechain and L2 they interact with. Having wallet developers do native integrations also just does not scale (only 24hrs in a day and they probably have other Cardano features they want to focus on). 

To tackle this, we’ve developed a system called Wrapped Smart Contracts that allows users to call Milkomeda smart contracts directly from Cardano wallets (Nami, Eternl, Flint and more) without any extra work on behalf of the wallet developers.

You can find more information at https://docs.milkomeda.com/category/wrapped-smart-contracts

The project is (at time of writing) undergoing final integration by partner dApps before officially going live.

Notably, the project consisted of the steps:

1. Writing the specifications
2. Integrating the system inside the EVM itself on Milkomeda (precompiles)
3. Integrating the systems inside the Milkomeda bridge
4. Coordinate a hardfork of Milkomeda to introduce these upgrades
5. Having partners integrate Wrapped Smart Contracts into their dApps

[IMPACT] Please describe your proposed solution.

This will help adoption of sidechains and L2s in the Cardano ecosystem which gives more power to developers to create custom environments for their specific needs without having to worry about losing adoption because of it

[IMPACT] How does your proposed solution address the challenge and what benefits will this bring to the Cardano ecosystem?

1. Number wrapped smart contract calls made
2. Number of dApps that integrate wrapped smart contracts

[IMPACT] How do you intend to measure the success of your project?

We will share any code or documentation we wrote for the implementation publicly so that any app or game can integrate the functionality

[IMPACT] Please describe your plans to share the outputs and results of your project?

[CAPABILITY/ FEASIBILITY] What is your capability to deliver your project with high levels of trust and accountability?

dcSpark and Milkomeda are well renowned companies in the Cardano ecosystem that have a long history of delivering on Catalyst proposals. You can find progress on grants we have previously received at https://dcspark.io/grants

[CAPABILITY/ FEASIBILITY] What are the main goals for the project and how will you validate if your approach is feasible?

The main goal of the project is to make it easier to onboard users into the sidechain/L2 ecosystem. Many potential users do not want to create new wallets for each different execution layer, and we want these users to be able to easily onboard with as few hurdles as possible

We know this project is technically feasible as we have already built it and are in the final stages of testing

[CAPABILITY/ FEASIBILITY] Please provide a detailed breakdown of your project’s milestones and each of the main tasks or activities to reach the milestone plus the expected timeline for the delivery.

1. Release the specifications
2. Complete the Milkomeda hardfork
3. Upgrade and audit the Milkomeda bridge
4. Announce partner integrations of Wrapped Smart Contracts into their dApps

[CAPABILITY/ FEASIBILITY] Please describe the deliverables, outputs and intended outcomes of each milestone.

1. Public documentation
2. Announcement
3. Audit release
4. Announcements of integrations

[RESOURCES & VALUE FOR MONEY] Please provide a detailed budget breakdown of the proposed work and resources.

1. 30k
2. 20k
3. 30k
4. 20k

[RESOURCES & VALUE FOR MONEY] How does the cost of the project represent value for money for the Cardano ecosystem?

This provides value by increasing the amount of use-cases that can be built in the Cardano ecosystem as projects that require a sidechain or L2 are now much more viable from a business perspective

[IMPORTANT NOTE] The Applicant agreed to Fund10 rules and also that data in the Submission Form and other data provided by the project team during the course of the project will be publicly available.
