WBTC propAMM just dropped Very different curve than the previous graph! Showed against uni 5bp (green) and 30 bp (orange) Also added a zoomed in version so you can see the price movements. Notice how much more adjustment there is for the prop vs 5 bp pool
Here you can see the same propAMM vs Univ3 5 bps. For small trades the propAMM is tighter, but then widens out for bigger trades This behaviour makes sense while the systems are new and makers are feeling it out. Quoting wide for big trades is a good way to minimise exposure to toxic flow integrate now and ride the wave of tightening spreads on ethereum (link below)

🕊️ Contender v0.10.2 is now available with a new spam-stream mode for piping tx definitions into Contender as JSON, plus scenario-level access lists and configurable/fuzzed EIP-1559 priority fees.

if ur interested in helping out with VoxTerm, a local first and private by default transcription tools with ✨ fun features ✨, we're looking for help in better diarization, more efficient voice profile embeddings, and built in privacy filters and redactions! ⬇️
Updates since then: * Deepseek v4 is out. There *is* a 2-bit quant that can run within 90 GB ( huggingface.co/antirez/deeps… ), and it works, however it's only fast on Apple hardware (I've head ~35 tok/s). On AMD, it's ~7 tok/s. IMO actually taking the effort to properly support more than one hardware manufacturer is a great example of the difference between mere "decentralized AI" and genuine "CROPS AI". I hope we can become better at this. * github.com/vbuterin/messagin… also has alpha telegram support now. However, the path to adding your account is quite janky * github.com/Luce-Org/lucebox-… looks promising as a way to run "dense" models (eg. Qwen 27B) more efficiently. It's janky, but on my 5090 laptop it seems to be ~2x more tok/s than llama.cpp * VoxTerm (local AI recording, no third-party servers) continues to be developed github.com/dmarzzz/VoxTerm And there's a lot more projects coming on the horizon. One other thing that has been on my mind is that there's actually a lot of intersection between "CROPS ethereum access layer" and "CROPS AI". For example, we want a ZK way to make (paid) calls to remote LLMs. But if we have this, then it's just as useful for solving another problem: private RPC reads in Ethereum. Another example: application-specific finetuned LLMs. Leanstral ( mistral.ai/news/leanstral ; I get ~38 tok/s on AMD) fits into < 70 GB, but can hold its own against 1T models on writing Lean code. Things like this are a huge boon for writing more secure code ( vitalik.eth.limo/general/202… ). We should have models finetuned for Ethereum-related use cases as well.

🕊️ contender v0.10.1 Highlights: - improved RPC/server stability and ergonomics - fixes for several edge cases in long-running spam sessions - cleaner report generation and metrics handling - better library integration support for downstream rust projects - each crate is now versioned independently ⚠️ If you're using the RPC server, please upgrade now. v0.10.0 has bugs that can lead to extreme CPU usage, which have been patched in this version.

the server also hosts a dashboard to interact with it; all contender CLI functions are supported (plus some extras, like on-demand spammer account funding)
🕊️ Contender v0.10.0 Contender's JSON-RPC server is now live — run (many instances of) Contender as a service and control it over HTTP. Drive Contender from any app: add & trigger scenarios, adjust params as you go, start/stop runs, and pull metrics & logs on demand. No CLI glue needed. This unlocks much more advanced testing setups—dynamic workloads, coordinated multi-node tests, CI pipelines, and external orchestrators. Also: - combined callback system - tx success/failure tracking - typed init state (compile-time safety) in Contender lib - ETH-denominated min_balance - improved logging (tracing spans, better spam logs) - minor fixes (server logs, callback error handling)

it also hosts interactive OpenRPC docs, so you can start integrating contender into your node testing setup with ease

I'm excited to see what people build with this. If you plan on using the contender API in your project, send me a DM!
