Mantle transaction simulation requires preparing a handoff package that captures pre-state like balances and nonce, selects an external simulation backend, and produces a structured report with WYSIWYS summaries, gas estimates, and revert analysis for pre-signing review.

WYSIWYS (What You See Is What You Sign) translates technical simulation artifacts like state diffs and logs into user-readable summaries, allowing teams to review expected on-chain effects before broadcasting transactions or signing multicall bundles.

Mantle transaction simulation applies to individual transactions, multicall bundles, and pre-execution checks across both testnet and mainnet contexts, normalizing transaction requests and capturing required pre-state for comprehensive bundle verification.

Revert analysis for Mantle transactions involves capturing pre-state including balances, allowances, nonce, and gas context, then running an external simulation to collect status, logs, and state diffs for a standardized simulation report.

When simulation confidence is insufficient, the simulation report enforces guardrails by providing a preliminary WYSIWYS and setting explicit do_not_execute reasons, ensuring read-only operation prevents unsafe transaction broadcasting.

Mantle simulation enforces read-only operation guardrails to perform pre-execution checks, capturing pre-state and producing simulation reports with gas estimates and state diffs without broadcasting the actual transaction.
