We will launch the Printer and Credit Lines in the coming weeks and start setting up an ecosystem for the jFIATs there.

The jEUR’s bankroll owners have deposited 15k more jEUR, increasing the maximum payout capacity! Players can earn up to 420 jEUR playing Dice, Roulette, or Coin Toss games!

Thanks to the generous contribution of Mimo Capital, who are using their vlAURA to vote for the 2eur (PAR) gauge, there was no need for voting incentives.

A WETH-jUSD Synthereum’s Liquidity Pool was deployed and seeded, allowing for 0-price impact swaps between WETH and jUSD. We will soon launch a WETH-jUSD Credit Line too.

Two weeks ago, an article (in English) was published to highlight the ecosystem around the BRZ token.

We also deployed a new [Gnosis Safe](https://arbiscan.io/address/0x39BAFa9F4c4DcE3Eac9333cEB7FEeC03C9DD4682) for the treasury and updated the [documentation](https://learn.jarvis.network/). * 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 analysis](https://storage.googleapis.com/papyrus_images/be17237d02e8e045e59222a3e6bcc36300af4488d018a0eb193bf1414c0c2882.png) Chainlink price feed analysis * The DeFi Llama team has approved our merge request to fix an issue with calculating the TVL of the protocol on their website. ![](https://storage.googleapis.com/papyrus_images/b09de3e7f88520d3a0b51c0210cda43f9e5cfc2485a69d412bcd62e63ba981b5.png) * We have launched three sub-graphs for [Polygon](https://thegraph.com/hosted-service/subgraph/saywhatdev/jarvis-network-fees), [BNB Chain](https://thegraph.com/hosted-service/subgraph/saywhatdev/jarvis-network-fees-bnb), and [Optimism](https://thegraph.com/hosted-service/subgraph/saywhatdev/jarvis-network-fees-op). 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](https://tokenterminal.com/) or [Cryptofees](https://cryptofees.info/). 📱Applications -------------- ### Jarvis Exchange * We 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 Money * We 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.](https://storage.googleapis.com/papyrus_images/ceaf906b5614b6d3c815e3975f85fef63912e864b48dcb5142403dd8cae2a95f.png) User Interface of the borrowing app. ### JARVIS Token dashboard * We have started the design of the application around the veJARVIS token. ### MISC * We 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. 🗳️ Governance -------------- ### Discussions * p84: this new discussion is about changing the governance structure to speed up some processes. The idea would be to elect governors and a budget and give powers and goals to those governors. ### Proposals _No new proposal._ --- *Originally published on [Jarvis Network 🧪🦇🔊](https://paragraph.com/@jarvis-network/jarvis-week-51)*
