Recap/report on my scattered activities during week 0:

## Done
### Research:
- Read:
    - https://eips.ethereum.org/EIPS/eip-4337
    - https://docs.stackup.sh/docs
    - https://notes.ethereum.org/@yoav/unified-erc-4337-mempool
    - Edennetwork'm articles on AA ([1](https://medium.com/edennetwork/the-next-billion-users-exploring-erc-4337-account-abstraction-part-1-1cf5888565a3), [2](https://medium.com/edennetwork/erc-4337-exploring-the-technical-components-of-account-abstraction-part-2-fec300a7f052), [3](https://medium.com/edennetwork/erc-4337-elephant-in-the-room-6c5f8526d562))
- Watched:
    - https://www.youtube.com/watch?v=G0nFyq9DDPw
- Explored(Run, Look into design, Reviewing code):
    - https://github.com/eth-infinitism/bundler
    - https://github.com/vid201/aa-bundler
    - https://github.com/zsluedem/UoIndexer

### Development:
- Started 4337 block explorer development [[will live here](https://github.com/behkod/aa-explorer)] using Yew, Actix, TheGraph (While also exploring other options as the indexer & viewer for different modes of operations for bundlers)


## Next (couple of weeks)
- Research:
    - on different (so-called) modes of Bundler operation: private, searcher, conditional
    - https://github.com/eth-infinitism/bundler-spec/blob/main/p2p-specs/p2p-interface.md
- Development:
    - Coding Block Explorer

## Plan:
I'm starting with block explorer as the **starting step** into the AA ecosystem. After launching an initial version, I'll continue to pick other issues in AA, but coding the explorer would definitely give me a better view & more time to choose the right path to move forward while still remaining productive.
