### Pierre-Alain Ouvrard
- Prototype NEAR <> Aurora bridge UI
- Bridge new tokens
- Newly bridged tokens need metadata and "aurora" account storage fee before it can be sent to Aurora.
- Transfers both ways (ERC-20)
- Webapp pre-release
- https://aurora-testnet-git-pa-aurora-exit-auroraisnear.vercel.app
- ETH exits from Aurora
- aurora-erc20 connector lib
- Restore functionality for all tokens
- Setup metadata repository
- https://github.com/aurora-is-near/bridge-metadata

### Yulian Lavysh
- Content. Collaborated with Michael and Alexei and started a process for a longer term strategy around content
- EthCC coordination
- Localization - setting up a process with Matt
- Team page on the website

## Discussion
- Param estimator on `ecrecovery`
- Bowen: is there anything else rather than the gas estimation what needs to be done?
- Joshua: no
- Evgeny Kapun: still need to review small changes
- Bowen: param estimator is not working right now, Nikolai is working on this. Bowen to consult with Max on this issue
- Arto: similar issue was observed in May
- Joshua: 10M accounts size is not working, so need to be reduced to 500k - 1M; 20k accounts works well
- Perhaps there're problems with bash script
- Bowen: in case the param estimator won't give results then we need to push back the release
- Arto: perhaps we need to overestimate the costs and later reduce it (when param estimator is fixed)?
- Joshua & Bowen: there're some estimations, but we need to consult with Max on it
- AI:
- Evgeny Kapun -- to review the updated code
- Bowen to consult with Max on estimates & propogate the feedback
- Ethereum state prover on NEAR
- Update on the state prover development
- Evegny Kapun: token metadata won't work as intended
- AI: Evgeny Kapun to provide a list of extensions to the current bridge which may help by Monday team call
- Tx block execution
- https://explorer.testnet.near.org/transactions/5eukZxsNfsyWjFoDyYBdjBD4NogubHHSZTCc1Ejzqvzi
- Transaction execution is split over at least two blocks => we need to make sure that nonce changes are observed at right call
- There's no upward bound for the finalisation of the transaction
- Normally it takes less than 5 blocks
- AI: Arto to take care of this next week. Relayers need to re-index all the transactions. This will make possible to roll put the block explorer
- DAO approach (Matt)
- SputnikDAO supports voting on binary questions, yes/no. We need to support more complex question types, like choosing N of M from an enumerated list. OTOH, SputnikDAO supports things we don't need, like multiple DAOs; we only need one.
- Question: Should we fork SputnikDAO, calling it AuroraDAO, tailoring it to our own needs, or try to extend SputnikDAO. The former seems like the right choice: We can move faster, since we can implement in specific ways, rather than having to consider generalized approaches.
- AI: Matt/Alex to chat with Illia on the plans on SputnikDAO, previously preparing the requirements.
