## This week

### Ahmed Ali
- Hiring (Shadowing Marcelo).
- Documentation:
- [Aurora-docs#16](https://github.com/aurora-is-near/doc.aurora.dev/pull/16).
- [Aurora-examples#ERC-20](https://github.com/aurora-is-near/aurora-examples/tree/main/hardhat/erc20).
- Troubleshooting

- Telegram Aurora-dev support.
- RPC-Relayer onboarding (Kudos to Arto).
- Reviewing the bridge article.

### Alex Shevchenko
- 30+ investors calls
- Started the company incorporation and relevant docs preparation

- Supported of the Rainbow Bridge
- Finalised the org chart, compensation and benefits

### Arto Bendiken
- Funded the Testnet faucet with 10,000 ETH from Ropsten.
- Kudos to GB at the Ethereum Foundation!
- If anyone in the team needs some Ropsten ETH, I’ve still got a lot of ETH left on Ropsten as well

- https://github.com/aurora-is-near/aurora-relayer/issues/19
- Worked on admin matters: hiring, interviews, HR matters and comp convos, fundraising.
- Continued work on standing up the Testnet block explorer:
- Need to backfill the 50M historical blocks, which we also don't have indexed in our RPC endpoints as yet.
- Way too slow to let BlockScout index it itself via the RPC, so formulating a better solution.

### Marcelo Fornet
- Precompiles (Already green in CI only missing End to End test)
- https://github.com/aurora-is-near/aurora-engine/pull/51
- Working close with Pierre on the integration of the frontend with Eth+Erc20 transfer to Aurora
- Add support for "removing" storage in Aurora using generation key. (Updated and merged)
- https://github.com/aurora-is-near/aurora-engine/pull/84
- Update EVM to provide access to state from precompiles (merged)
- https://github.com/rust-blockchain/evm/pull/33
- Add support in near-api-js for view functions that receives borsh serialized arguments:
- https://github.com/near/near-api-js/pull/620
- Finalization relayer
- Deploy to Google Cloud + add basic monitoring
- Minor updates and bug reports
- Update docker image for rainbow-bridge
- Hiring

### Matt Henderson
- Aurora fundraise internal activities & investor reach-out
- Aurora setup activities
- Blog article about Rainbow Bridge
- Miscellaneous admin issues (upgrading some commercial services we use)
- Coordination around features related to Aurora bridge:
- ERC-20 transfers on Testnet
- ETH transfers on Mainnet
- Auto-finalization of ERC-20
- Check that Ethereum to Aurora transactions are actually finalized
- Exiting back to Ethereum
- What we didn't get done:
- Launch of ERC-20 on Testnet, due to inter-relations of some of these pieces. On the positive side, next week we beleive we'll be able to get bi-directional ETH and ERC-20 transfers on both Testnet and Mainet.
- What we got done:
- Finished Restore workflow (needed when exiting back to Ethereum)
- Started a design around synchronization and transfer filtering (should reduce need for restore)

## Discussion

### Usage stats (Arto, Alex)
- The last month: ~2M total requests to the endpoints, 2K+ attacks blocked
- The last 24h: ~100K total requests to the endpoints
- Any good tools for on-chain stats? For example, we should track the number of `submit` and `deposit` calls (and with a succeeded/failed dimension).


- Rainbow Bridge [stats](https://duneanalytics.com/zavodil/rainbow-bridge)

### ETH bridge video explainer
- https://testnet.aurora.dev
- Michael is up for this task

### Telegram group spam
- Suggesting to add bot(s) for cleaning any unncessary messages (e.g., [@MissRose_bot](https://t.me/MissRose_bot)).
- We have a couple of bots already added as admins
- Yulian to take ownership on this

### NEAR Bully?
- Success of Aurora depends on NEAR, so it's worth to help NEAR to deal with the issues in the protocol.
- NEAR Bully idea: to make a load/fuzzy testing tool for NEAR
- Michael: there's a load testing tool already. It works in the `Mocknet`.
- Frank to sync with Max & others on this matter.
