We built Panda, a CLI/MCP tool that lets agents work directly with our observability data.
We found that if you give the agent a code sandbox and a library for your stack, things start to click together very nicely.

We've learned some lessons along the way. This one is a must read for anyone seriously using agents (even outside of Ethereum!)

Claude Opus 4.8 takes the top spot on EthIQ with a score of 88%!
Introducing Claude Opus 4.8: it builds on Opus 4.7 with sharper judgment, more honesty about its own progress, and the ability to work independently for longer than its predecessors.
Available today at the same price.
ALT Benchmark table showing how Claude Opus 4.8 compares to its predecessor and to other models on tests of coding, agentic skills, reasoning, and practical knowledge work tasks.

We built a simulator for the fast confirmation rule, and replayed a years worth of blocks and attestations on Mainnet.
Across 800,000 mainnet slots, roughly 96 out of every 100 slots would have been fast-confirmed within 12 seconds.
Zero false confirmations.

New in The Lab: Validator Report.
Paste validator indices, pick a range, scan performance, and drill from day -> hour -> slot to find exactly what happened.
Catch missed proposals and head-vote drops faster.

It turns out some AI models can step through EVM bytecode in their head.
We built EthIQ, a new benchmark to test how well models actually understand Ethereum protocol internals.
325 questions across two evaluation modes, and one alive canary 🐦

We tested 44 models across EVM execution, consensus state transitions, fork choice, and more. Anti-memorization is baked in. Inputs are mutated from the official spec fixtures so training data is ruled out.
The results were... surprising.

New in Xatu: Execution trace data.
Per-opcode gas consumption for blocks/txs. 9 new tables covering call frames, opcode gas, and daily/hourly aggregations.

Also shipping a Gas Repricing Simulator. Pick a block, change any opcode cost, and re-execute it. See which transactions break, which exceed the gas limit, and which flip between success and failure.

New feature now available in The Lab slot deep dive 🚢🚢
Trace the timings of a slot from all the Xatu nodes. Includes MEV bids, block arrivals, execution times (where available), and data availability time.
Link in next tweet.

BPO2 landed last week. It bumped the max blobs per block to 21. We've been going through the data.
Initial analysis doesn't look good! Have a look at this scary chart. But there might be more to this story..

Now that we've established this relationship we can check from a blob count POV.
Boom!
The green line is holding up as the blob count increases. The red line shows the cause of our pain from the first chart.

While it's tempting to jump to the conclusion that the network supports more blobs - this would be very premature. This data is a single chapter in a vastly complex book.
To these entities playing timing games - keep an eye on your infra with blob count increases!
More to come!
