Introducing mevlog.rs! Explorer with flexible querying for over 2k EVM chains, powered by @chainlist_team public nodes. Thanks to @ensdomains for a dev grant making this release possible! Try sample queries here mevlog.rs/search
…and allocates. btw shoutout to @fornwall for the awesome github.com/fornwall/alloc… crate that allowed me to implement memory profiling

released a smol perf lib. hotpath is a lightweight, easy-to-configure Rust profiler that shows exactly where your code spends time github.com/pawurb/hotpath
github.com/pawurb/mevlog-… new —sort mevlog search -b 1000:latest --sort "erc20Transfer|0x6982508145454ce325ddbe47a25d4ec3d2311933" --limit 1 --chain-id 1 --format json-pretty | head find mucho pepe
csv -> parquet. same perf but 4-8x smaller cache size
In-memory sigs cache, over 30x fewer sqlite calls, and 2x better perf
New UI for mevlog.rs cooking. A simple way to find overpriced txs across multiple blocks and custom search conditions. Works with every EVM chain on public RPCs. Hope to release in a week or two.
UI overhaul in progress, meanwhile JSON output on main github.com/pawurb/mevlog-…
Better UX just shipped to github.com/pawurb/mevlog-… CLI chains cmd to list available (>2k) EVM chains from ChainList rpc-urls cmd, show RPC endpoints sorted by response time set —chain-id instead of —rpc-url to use the best public RPC endpoint
Love this innovative new feature by @RevolutApp. Auto-subscribing users to a paid plan without their consent 👌
