We also deployed a new Gnosis Safe for the treasury and updated the documentation.We developed and tested the Debt-Token smartcontracts on the Mumbai testnet. We will soon deploy it on the Polygon Mainnet.We have found a satisfactory solution to solve the issue with the “dust” in the Credit Line v3, and have implemented these changes. All the tests were conclusive, and Credit Line v3 is awaiting its final peer reviews before its audit.Following the Liquidity Provider Vault audit, we are reviewing the latest updates to the code and testing the Vaults on the testnet.We have conducted a 6-month analysis on all the Chainlink price feeds we are using across all the networks deployed to adapt the trading fees of the pools accordingly. More specifically, we were looking for statistics about price deviation between two updates (average, maximum, standard deviation, number of deviations below a certain threshold etc.). We found the results very good despite some spikes that happened one or two times during the weekends, and we will need to work on preventing price updates when the underlying market is closed.Chainlink price feed analysisThe DeFi Llama team has approved our merge request to fix an issue with calculating the TVL of the protocol on their website.We have launched three sub-graphs for Polygon, BNB Chain, and Optimism. These sub-graphs allow for tracking the fees generated by the protocol, which was a mandatory requirement to list the Synthereum protocol on websites such as Token Terminal or Cryptofees.📱ApplicationsJarvis ExchangeWe have added jUSD and jGOLD on Polygon.We have fixed an issue with the displaying of the fees.We have added the Collateral Swap feature.Jarvis MoneyWe have worked on some UI and UX issues of our borrowing app.We have added a “Warning” message since Credit Line v2 has not been audited.User Interface of the borrowing app.JARVIS Token dashboardWe have started the design of the application around the veJARVIS token.MISCWe completed the design of the Debt Token application has been designed, and we have started the development of the application.We started drafting an application to centralize everything, from voting to staking to swapping to bridging or on/off-ramping etc. This application will replace all our applications.🗳️ GovernanceDiscussionsp84: this new discussion is about changing the governance structure to speed up some processes.
