This proposal had been blocked on some refactoring work needed for CML. Thankfully, our tooling team identified the blocker and is working on it. More specifically, basic groups inside arrays weren't supported for generation. Cddl for dRep has such structures inside. You can learn more about the issue and progress at the Github link shared

The wallet connect team built a general-purpose library for connecting solana wallets and integrating wallet connect with solana. We’re using this liblary as a reference to build general-purpose cardano connection library with wallet connect support. Our next step is to: Finish implementation of the Cardano library Make a PR on the WalletConntect modal library that integrates the Cardano library Adding the WalletConnect paring to Flint. For the Cardano library implementation we’ve finished implementing the inject connector (for desktop-based, browser-injected cardano wallets, finished implementing the wallet-connect connector. In the coming weeks, we will complete the creation of the SDK and documentation, thereby completing the Proof of Milestone 1 for this grant.

This report is to provide an update on the progress of the audit of the Liquid-staking smart-contracts. The audit was initiated on December 12th, with the well-known auditor Arbitrary Execution. The audit is expected to be completed in the middle of January.

Background:

The Liquid-staking smart-contracts are an important part of the Milkomeda ecosystem, allowing users to earn rewards by staking their tokens on the sidechain. It is critical that these contracts function correctly and that rewards are properly distributed to users.

Audit Process:

The audit is being conducted by Arbitrary Execution, a reputable and experienced auditor in the field. The audit process involves a thorough review of the code, as well as testing to ensure that the contracts function as intended. The audit team will be looking for any potential vulnerabilities or issues that could impact the functioning of the contracts.

We are confident that the audit being conducted by Arbitrary Execution will provide valuable insights and help ensure the continued smooth functioning of the Liquid-staking smart-contracts. We will provide upload the audit results as a PoM2. Soon we should also add NPM Package for the Liquid Staking project thus completing PoM1. In the meantime, more information on the Liquid-staking contracts and their role in the Milkomeda ecosystem can be found at the following link: https://github.com/dcSpark/milkomeda-documentation/blob/liquid-staking/docs/cardano/liquid-staking/c1-overview/bridge-logic.mdx.

In the meantime, we have begun work on the UX&UI of Staking DApp, which we present in the evidence section.

Over the past month, our team has made significant progress in the development of our Unity frontend build. One of our key objectives during the Proof of Milestone was to demonstrate video proof of gameplay featuring both attacker and defender structures and units.

I am pleased to report that we have successfully achieved this goal. Attached to this report is a short video showcasing the gameplay at its current stage. In the video, users can see the attacker's structures producing attacking units and the defender's structures destroying those units.

Overall, the game is already fully playable from both the attacker and defender perspectives. This is a major milestone for our team and a testament to the hard work and dedication of our frontend developers. We are excited to continue building and improving upon this foundation as we move forward.

While we've confirmed that we will be working with a partner (txpipe team) on this proposal, we are currently blocked on their developer bandwidth. Once they have resolved this we will be able to move forward as normal. Factoring in the holiday season, please expect an update for January Monthly reporting.

Last month we reported that the storage needed to be optimized for large datasets. Unfortunately, we didn't perform many changes in scalability direction in the past 2-3 weeks. Things should be back to normal next month (Jan '23)

  • Plutus version was updated.
  • Script architecture was updated to enable some fixes, mainly the introduction of the validity token.
  • Offchain code was maintained and kept in line with the changes and the new architecture.
  • Tests were maintained and kept in line with the changes and the new architecture.
  • New tests for audit findings are added to show that they were failing before our changes and are passing with them. As planned, we are implementing our grant proposal. On November 28 we will start the final part of our audit with external contractor. ETA on that is 2-3 weeks, so we will provide a more detailed update as part of the December reporting.

According to Milestone 1, we provided documentation on the basis of which the proposal solve assets fractionalization will be implemented. Milkomeda liquid staking documentation includes basic elements:

  • Bridge Logic
  • Rewards claiming
  • Contract Overview
  • Tokens models
  • Desirable properties of liquid staking protocol for Milkomeda

We are working on special smart contract, Creating the sstMilkADA token and creating NPM package for contract usage.

Currently, we are still working on developing the environment and game logic, but the first internal demos are achieving very good results and we are pleased with the progress of the team. We are presenting some graphics to keep the vision of the game a secret before the first official announcements.The following is a list of the graphical assets for the units, structures, map, and title screen.

The working prototype of the storage is implemented. The storage needs to be optimized for large datasets and index size / speed can be improved as well. Needs to be done so the library can support writing large files (e.g. 100gb).

Initial code generation has been done using the cddl-codegen library (Link 1 in our references) Mixed v1 + v2 version is currently under review, please see Link 2 to see the process so far. As soon as the review is done, the library should be put into a separate crate in CML, and we'll need to publish crate & npm package. CML & publish steps are blocked by CML refactoring (workspace), should be unblocked next week
