Research

Mempool Transactions that are way too expensive to be executed and can’t be replaced https://gnosisscan.io/tx/0x187037824111a2bbc106c63881e34115cc1f4daf9d5e50899bc8e74b1ae3ad04 https://gnosisscan.io/tx/0x767da6692a34117f42869b9780f4752f61d8119b3e2d62d0f79e72c406e428f0 Transactions that are too cheap and will never be executable https://blockscout.com/xdai/mainnet/tx/0x0adeb6c464c37c86145f135fb9e9252ca504d5706226b7b250ddfb05e42075b8 Small oversight because it’s a local transaction, but shouldn’t be an issue Nethermind will fix this, but it’s no big deal Will get evicted if a more appropriate transaction comes in

Tests

Hive: Good progress pre and post-shanghai. Implement tests for post-shanghai scenarios. Syncing status: Producing blocks and sending transactions. Verified that withdrawals work like expected. Not getting the expected results. But the root is built correctly and the withdrawals are indeed being executed. Later (timeline: 2-3 weeks) Block reorgs and syncing issues. Edge cases: Integrate Erigon. Making sure that everything integrated with Nethermind also works with Erigon.
