Abstraction & UX are of critical importance for enabling the next wave adoption.Solutions that take the time to properly address them stand to gain a decisive competitive edge.Weekly #multiversxtech 🛠️

1/ The Guardians feature has been deployed on testnet, and with this occasion we invited the community to an incentivized hacking competition. Several topics that have been pointed out are already fixed, such as the limited denial of service for accounts with leaked keys.

2/ Created a WebSocket connector template for the Outport Driver that facilitates seamless exporting of blockchain data (such as blocks, validators, and processing results), useful for dApps, network monitoring and data analysis.

3/ - Reviews and specifications on the Output transfer ordering for all kinds of scenarios with a focus on ensuring deterministic execution and order on multiple cross shard calls and callbacks.

4/ Other notable achievements:- Testnet T1.5.4.0 release after guardians' competition findings fix
- Finished implementing a feature which will sync missing trie nodes from network if they are not saved in storage
- Written semi-integration tests for different scenarios

5/ - Further testing & optimisation on the concentrated liquidity base implementation SC
- Finished transfer ordering
- Wrapping up some log events updates
- Final touches on the Safe Price mechanism

6/ - Started implementation of a robust mechanism that facilitates the transmission of node configurations over a WebSocket when a request is made for seamless retrieval and querying of data
- Implement general NFTs analytics query
- Update staking contract tutorial documentation

8/ - TCS:
- Added extra fields on /register route response, in order to provide url for 3rd party apps also, not qr code only
- Improved the errors returned on API level, as internal server error was used for most of the cases
- Reviews + testing on latest changes

9/ - Further development of system tests targeting the VM
- Integrated the WebSocket template into a custom solution to enable firehose integration and developed additional scripts to facilitate the necessary setup for testing the integration

10/ - sdk-js - minor release of sdk-js-wallet
- Bugfixes on the component responsible for computing transaction gas fees in the outport driver
- mxpy contract verify update to specify contract name when using verifying a multicontract
implemented "cold" signing with mxpy

11/- Add guardian support for mxpy
- Bughunt & bugfixes on the WebSocket host to ensure uninterrupted message transmission even when no clients are connected to the server
- Debugging and testing support
- sdk-py - BLS signing support for M1

12/ - Working on copying data from ES indexes to Google Big Query
- Improvements on the reproducible builds flow (support for multi-contracts) - version not yet released
- Testing on: xLaunchpad, Delegation manager, xExchange API
- Epochs fast forwarder on internal testnets

13/ - Stress testing guardians
- Enable the extension for the guarded account protection in case of compromised account by allowing the user to set again the active guardian in pending state, which doubles protection time
- xLaunchpad API improvements

14/ - KYC service testing
- Multi tokens transfers via relayed transactions semi-integration test
- Finished the task that brings consistency into tokens transfers values checks
- Configurable shard blocks finality analysis and first implementation

15/ - Redis helm chart and mainnet redeploy
- Internal testnets elasticsearch indexer setup
- Review on new log events standard, which enhances the information for developers and users for the information that passes between SCs
- Added new contracts labels

16/ - Boosted metastaking upgrade fuzz tests
- Updated prometheus metrics for guardians service
- Redis cacher implementation and testing for guardians service; this will replace current local cache implementation that is not suitable for scalable solutions

17/ - mx-sdk-py-exchange refactors & dev
- Extended documentation for Governance off-chain and on-chain process for xExchange
- Working on ARM64 build and repository for a set of our solutions

18/ - Specifications for community farms, farms with multiple rewards, new mystery box lottery SC
- Distributed locks implementation for guardians service, based on redis
- Prototype for a smart contract static API for tests, routed through the VM executor interface

19/ - Fixed an undefined behavior in the VM in an edge case
- Added new unit tests & bugfixing on MultiversX API
- Added more testing scenarios on twisbox orchestrator
- Guardians testing

20/ - Debugging various issues on cards microservices
- New indexer testing
- System test scripts improvements
- Testing all incoming branches

21/ - KYC service: backoffice: /accounts, /pending-accounts, /history, /stats and  general pipeline verification after KYC validation
- Finished new price discovery charts data
- Optimised escrow queries with events handling

22/ “Stay Hungry Stay Foolish” and tune in soon for more of the #multiversxtech which powers the @MultiversX ecosystem.
