🟢resolve_abi(chain, address, method_q, method_kind, method_limit, ...)

Resolve a contract's interface from chain + address via a fallback ladder (Etherscan → Sourcify → proxy → heimdall decompile → 4byte). Returns a compact capability manifest (read vs write functions, the 'buttons'), proxy chain, token metadata, and PROVENANCE. ALWAYS read `provenance`: a `decompiled` ABI has synthetic function names — treat it with care and confirm intent before writing. Partial, proxy, and bytecode-match results lead with a WARNING before the JSON. The compact manifest/provenance is also returned as structuredContent. Use method_q/method_kind/method_limit for large ABIs. Raw ABI is omitted from MCP output to save tokens; use REST/SDK resolve_abi with include_abi=true if needed.

🟡prepare_tx(chain, address, function, args, from, ...)

Prepare a contract WRITE for the user to sign. Returns an UNSIGNED transaction, its simulation, a human-readable summary, safety metadata, warnings, a configured signing deeplink, and an EIP-1193 wallet request when signing is recommended. IMPORTANT: this tool NEVER signs or broadcasts. Present the summary + simulation + warnings to the user. Only hand them the `deeplink` or `wallet_request` when `safety.signing_recommended` is true. If `safety.risk_level` is high or blocked, make that explicit; blocked means do not send.
