Stacks Transaction Simulation

Pre-flight / dry-run a PROPOSED Stacks transaction WITHOUT broadcasting. Keyless and read-only — never signs, never broadcasts, never moves funds. Modes: action=transfer (from, to, amount in STX → estimates the fee and checks the sender's balance covers amount + fee), action=contract_call (contract_id, function_name, function_args, from → for READ-ONLY functions truly evaluates them against live state and returns the (ok …)/(err …) result; for STATE-CHANGING functions Stacks cannot read-only-execute them, so it validates the args against the live ABI, estimates the fee, and statically lists the asset-movement primitives the function uses — success/revert is not predicted), action=sellability (token_contract → a honeypot check that statically scans the SIP-010 transfer source for pause / blacklist / owner-only guards). Reflects current chain state — not a safety guarantee. Not financial advice.
