Someone verified wintermutes cexdex contract on etherscan lol. Onchain is now open source etherscan.io/address/0x51c72…
PAMMs are streaming quotes throughout the entire slot and without latest bid they will either have to quote much wider or save their quote for the very last moment
As part of Gloas, clients are considering adding the option to select the highest bid per builder per slot instead of last. We strongly advocate for not providing this option & encourage proposers & responsible builders to also advocate for this position.

Lets just say this was only the tip of the iceberg ;)
Following @wintermute_t 's alpha challenges, I thought I found easy money that everyone else had missed, only to hit several hurdles 😬 Read my post on my attempts to capture @Uniswap protocol fees by trying to claim the TokenJar on Optimism 👇 ashiq.co.za/posts/Scanning-p…

Implemented variants of these in my indexer. Quality of life improvement with a mcp integration is huge for onchain research
Excited to propose five new JSON-RPC methods to fetch EVM blockchain history: blocks, transactions, logs, traces, and native transfers.
These methods address longstanding Ethereum data problems at the protocol layer, through an open standard that any EVM chain can adopt.

Spamming frontends on everything is a highly underappreciated aspect of AI. Fable 5.1 has some very sharp webdev skills. TG for notis, frontend for live controls & monitoring.

Sharing a silly Kalshi alpha I ran for low-mid 4 figs and 5 hours of weekend work since it's over now.
The newest season of Love Island recently aired, and funny enough, Kalshi had mention markets on nearly every episode for what the cast would say. Seasons are 6 episodes a week for 35–40 total. The episodes were not streamed, and the full thing was dropped immediately. Alongside this, the captions must also be included in the drop.
The obvious alpha was to figure out how to download the transcript right at drop and slam the correct market. Other people were doing this, but they had two issues. First, they bet the YES markets. The YES markets have slight subjectivity in that only the cast could say the words, meaning it required AI processing to gain confidence. Second, they were too slow :P
I reverse-engineered the API and figured out how to download the transcript a couple hundred ms after the drop, but instead of betting YES, I bought up all NOs for a guaranteed profit, as if something is not said, there is no way to lose. Since I knew the NOs, I could also sprinkle some small bets into YES without any AI processing.
Interestingly, after going straight to 99, people would still buy them back down, and I could sit for a few minutes and pick up some more scraps.
Unfortunately, I didn't notice the markets till the season was more than half over, and it became heavily insidered. Otherwise, this would have easily been over 5 figs.

Kinda neat strat by this guy to try to salvage his trapped USDT from the Altura wind down. The market has 0 USDT liquidity, so he flashloans USDT and liquidates an underwater position. That frees up enough liquidity for him to redeem his aUSDTP, repay the loan, and keep the AVLT (still pretty useless).
