The weekly #multiversxtech overview is here 🛠️ Our devs team had yet another productive week, check out the progress 👇

1/ The latest xExchange upgrade enabled Smart Contract addresses to have energy. This important change incentives project treasuries which usually involve multisigs to get exposure to XMEX and more primitives to be built on top. Energy DAO SC template: github.com/multiversx/mx-…

2/ Sovereign shards: created the first block that also includes transactions from the mainchain. Started implementation of sovereign chain block processing with shard headers notarization on the validator's side.

3/ Worked on ensuring proper order for transaction and smart contract results in cross-shard SC to SC call scenarios. New proposal for log/events of intra-shard SC to SC calls and enhancements to AsyncCalls generation and execution order.

4/ Other notable achievements:- Testnet release preparation for T1.5.1.0
 - Boosted staking smart contract test preps
- Finished the implementation on the web-sockets elasticsearch indexer

5/ - Minor fixes and refactoring in the state package
- Continued working on a feature that will sync missing trie nodes from the network
- Added support for guarded transactions for Ledger Nano devices and adapted the code for the new Stax SDK

6/ - Finished implementation of sovereign chain block processing with shard headers notarization in proposer’s side
- Change the node persisters to also allow the cleaning of the database
- Distribute data into multiple collections in mongodb for guardian service

7/ - ZK research
- Improved the code coverage on factory package
- Create script to integrate multisig in minting flows in typescript
