NOT AN AUDIT — simulation, not a guarantee
NOT AN AUDIT — simulation, not a guarantee: transaction dry-run ($0.10) — simulate any call against live public RPCs before you send it: would-succeed vs would-revert verdict, revert reason decoded, gas estimate in native + USD. Toll: $0.10 USDC on Base or Solana.
