The game is changing rapidly on Ethereum mainnet, expect to see these changes bring a lot of volume back. Once more builders onboard Titan's propAMM infra, I can see a world where mainnet spreads are tighter than Binance every block since it provides: - customizable adverse selection filters - automatic quote adjusting intra-block - protection against stale quotes being taken As a MM, the more control you have over who your counterparty is & your execution, the better.
1/3 PropAMM liquidity is now fully operational on Ethereum mainnet! Three makers are live in every Titan block, and quotes are already consistently beating Binance VIP9 taker fees for retail orders (trades <$1k).

One downfall of AI & vibe coding is that now my girlfriend knows I can create a decent looking CRUD app in < 2h, she wants a custom web app for everything. This must be what tradies feel like when they get tasked with "small weekend projects"

Eye opening that a single atomic arb bot on mainnet made ~12.5m, while only paying ~34m to the builder. I imagine most people have stopped playing the on-chain atomic arb game, those that stuck around ate good here.

correct me if I'm wrong but this seems like the largest ever single-block builder profit in ethereum history, ~$33m to titan it also may be one of the largest MEV block rewards ever on eth, a 568 ETH proposer payment which falls just behind the SVB USDC depeg (had a 692 ETH payment), 2023 sushiswap whitehat hack (689 ETH), and 2023 curve whitehat hack (584 ETH) others already commented on the original issues with the order (illiquid route insane $155k AAVE limit price), but here's where the $50m went: - $36k to the user's cowswap order (331 AAVE) - $619k cowswap solver fee - ~$9.9m to the MEV bot that backran the 17,957 ETH -> 331 AAVE swap (backrun was 128 AAVE -> 17,959 ETH) - another ~$2.6m to the same MEV bot from backrunning the $50m USDT -> $37m WETH swap over multiple txs - ~$34.3m fee to titan from the MEV bot (includes $1.2m to lido as the block proposer) - ~$3.5m in dex swap fees residual smaller arb txs insane payday for titan, who sent their profits to coinbase, and this single MEV bot took the majority of the arbs in both the illiquid AAVE/WETH pool and the $13m slippage swap in the main USDT/WETH pool

Side by side - V4 quoting and multi route search with and without poolscout.dev on @base Not only is it 2.5x faster, but you don't have to worry about RPC rate limits or brute forcing from known hook addresses.

Both processes follow a similar flow - discover V4, V3 & Velodrome pools - source quotes for each route direct on chain - report best path All paths and pools are cached locally in memory, so your agent can always find a pool to trade on.

This little sensor has surprisingly been one of the better qol additions I've made in the last 6 months. Didn't realize how bad the home office air quality got with 2 people working side by side and minimal ventilation. Highly recommend

Still need to figure out how to reduce the CO2 while keeping the room cool. A/C on and everything shut sends the CO2 to 850

Now I can harass Claude with unrelated questions while he does all my work for me
We just added /btw to Claude Code! Use it to have side chain conversations while Claude is working.

Why do LLMs appear to hate proper error handling? You'd think being trained on large sets of codebases, they would know that proper error handling and logging of errors is critical. But it appears they don't... Are most codebases not error handling properly?

For example, using Claude to write Rust. It loves handling results with `if let Ok(data) = ` rather than matching on a result and explicitly handling the error.

Is this just a way for the LLM to avoid conflict / be agreeable? If it doesn't capture any errors it can report that processes ran fine. If all errors are silent you never have any errors to report to your human

So @blockspaceforum drop their initial research scope & Flashbots release an update on Suave in the same week. Comp is heating up. So far they look like two different approaches - Flashbots the more theoretical & blockspace looking to be more iterative.

Outsourcing all my coding responsibilities to my @openclaw agent who then outsources to his own claude code instances locally. Middle management re-invented.
