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.

prepare_tx

Prepare a contract WRITE for the user to sign.

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.
