Publisher-provided description

Resolve any EVM contract ABI (even unverified, via decompilation), read, simulate, prepare txs.

Summary by lookupd

Resolves, decodes, reads and simulates EVM contracts and transactions, and prepares unsigned write transactions for signing.

Publisher-provided text

• list_chains List viem-backed chain aliases and ids. Use filters to find testnets, default-RPC chains, or a named chain before resolving contracts.
• runtime_metrics Read process-local resolver/rung/RPC counters for smoke checks and reliability dashboards.
• lookup_selector Lookup gulltoppr-proven signatures for a 4-byte function/error selector or 32-byte event topic0. Prefer these over public 4byte guesses.
• registry_stats Read selector commons counts by proof grade and bytecode-match index size.
• export_registry Return the CC0 selector commons as NDJSON. This can be large; prefer lookup_selector for normal agent workflows.
• resolve_abi Resolve a contract's interface from chain + address via a fallback ladder (Etherscan → Sourcify → proxy → heimdall decompile → 4byte). Returns a compact capabil
• read_contract Call a view/pure function and get the decoded result. No wallet, no cost. Rejects state-mutating functions.
• encode_call Encode a function call to calldata (0x…) without sending anything.
• simulate Simulate a call and return success, gas, decoded return, and best-effort state diff / asset changes / logs. Provide a high-level call (address + function + args
• prepare_tx Prepare a contract WRITE for the user to sign. Returns an UNSIGNED transaction, its simulation, a human-readable summary, safety metadata, warnings, a configure
• decode_tx Decode what a transaction did: delegated heimdall decode plus `decoded_call` from the resolved target ABI when available. Prefer `decoded_call` for typed functi
• resolve_name Resolve an ENS/Basename to an address, or an address to its primary ENS/Basename. Pass chain=base for Basenames.
