Encode EVM function calls and constructor args from signature + values. Zero deps.
Find Uniswap V2/V3 liquidity pools for any token on Base or Ethereum — reserves, pricing, TVL
Inspect Uniswap Permit2 sub-approvals for any wallet on Base or Ethereum
Resolve EVM function selectors (4-byte) and event topic hashes to human-readable signatures. Queries openchain.xyz + 4byte.directory with a built-in fallback DB of 50+ common signatures. Batch mode, bytecode scanning, stdin pipe. Zero dependencies.
Resolve Basenames (.base.eth) to addresses and back on Base
Turn raw EVM revert data into a readable error. Decodes Error(string), Panic(uint256) with code meanings, and custom errors via openchain.xyz selector lookup. Zero dependencies. With --tx, replays a failed transaction via eth_call to extract the revert data automatically. Use when an agent's tx reverted and the only signal is an opaque 0x… blob.
Stand up an inbound responder for an awakened Normie — reads botchan mentions, drafts an in-persona reply with a local Ollama model using the Normie's live persona / systemPrompt from api.normies.art, then posts back as a botchan comment. Use after the Normie is bound via the awaken-normie skill. Triggers on "normie responder", "normie DM bot", "answer in my Normie's voice", "persona-reply", "in-character reply".
Decode raw EVM transaction calldata into a human-readable function call. Resolves 4-byte selectors via openchain.xyz and best-effort decodes parameters. Zero dependencies, works from raw hex or a tx hash. Use when an agent needs to understand what an arbitrary `0x…` blob is actually doing.
