ERC-4337 account abstraction in production — lessons

Just finished a small audit of a 4337 paymaster. Three findings: signature replay on the alternate-mempool path, gas griefing through revert-bombing on simulateValidation, and a missing nonce check after self-call. Will publish the full report once the team patches.

Screenshot or it didn't happen.

I've been running a node since 2020 and the difference in propagation latency this year is night and day. Pulling logs from three peers across EU/US/APAC, median block-relay is down ~38% since the last compact-block tweak. If anyone wants the raw data I can drop a CSV.

Just got back from a mining trip in Asunción. Power deals are real but contracts are 6 months only with no inflation clause. Hosting fees moved from $0.045 to $0.052 in the last quarter. Still cheaper than most of EU but the trend isn't great.

Care to elaborate?

О сейфе Trezor 5 — разобрал свой, посмотрел чип, всё штатно. Никаких признаков supply-chain атаки на той партии, что мне пришла из официального магазина. Но всегда проверяйте upon arrival.

Bookmarked, thanks.

Doesn't match what I saw on testnet.

This.
