Blockchain mainstream adoption demands security solutions to be as foolproof as possible. The guardians feature will elegantly plug into MultiversX wallets to add an additional layer of on-chain 2FA security while keeping things simple and convenient. Weekly #multiversxtech 🛠️

1/ We defined the technical specifications of the xExchange on-chain and off-chain governance processes for community proposals. Continued development and started testing on the concentrated liquidity base implementation.

2/ MultiversX Bridge: preparations for new tokens whitelisting and added events listening for processing transfers with SC as depositor.

3/ Finished the first scenario for system tests targeting the new async call VM infrastructure and completed a refactor and redesign of the smart contract and test backend API interfaces.

4/ Other notable achievements:- Finished the new black-box testing framework written in go able to perform specific testing scenarios on any MultiversX chain
- Refactored old component which collects statistics about the trie
- Sovereign SC processor for incoming SCR

5/ - Improved logs on TCS API
- Created a tool able to generate SetGuardian transactions and send them periodically
- Firehose update with latest changes from outport refactor
- Internal testnets os bump to ubuntu 22.04

6/ - mx-analytics microservice pipeline
- Created the first tag of the mx-chain-communication-go repository
- Bug-hunt and bug-fixed on the /transaction/cost endpoint
- Added guardian support for mxpy

7/ - Guardians testing
- Finished the implementation of the WebSocket host: tested and merged in the release candidate branch
- Bughunt and bugfixes on MultiversX API and added new unit tests

8/ - Moved mx-chain-p2p-go repository to mx-chain-communication-go
- Testnet stress testing
- Finished trie sync optimizations task and unit tests
- Monitoring metrics for TCS service

9/ - KYC service testing, bug fixing & refactoring
- Started documenting all the tools existing in the ecosystem to put together a complete map for developers
- Further code testing & optimization on the new Safe Price mechanism

10/ - Historical liquidity analytics for xExchange
- Boosted staking smart contract testing
- mx-sdk-py-exchange improvements for usability
- Refactored checks for guardian builtin functions

11/ - Guardians system test

12/ - KYC: pending accounts and general pipeline validation
- Tb web api performance improvements; TbUsers refactoring; TbCustomers refactoring
- Added more unit tests and scenarios for guardian feature
- System test on all upcoming branches
- xFabric marketplace architecture

13/ - Guardians e2e testing
- Changes in the VM tests (updated the logs according to the new model)
- Blockchain-etl / our data on big query, work in progress
- Output transfer and SCR (re)ordering
- Threshold sig third party implementation review

14/ - Reviews and audits on new vm1.5 features
- Technical specification for output transfer ordering for SC to SC call
- Card API performance improvements and orchestrator microservice
- Crate renaming within SC templating
