resolve_abi — Resolve a contract's interface from chain + address via a fallback ladder (Etherscan → Sourcify → proxy → heimdall decompile → 4byte).
read_contract — Call a view/pure function and get the decoded result.
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.
decode_tx — Decode what a transaction did: decoded calldata (and trace when available), via heimdall.
resolve_name — Resolve an ENS name to an address, or an address to its primary ENS name.
