Solana Transaction Simulation

Pre-flight / dry-run a PROPOSED Solana transaction against live on-chain state WITHOUT broadcasting. Returns predicted success or revert (+ the program error), SOL/SPL asset changes (who gains/loses what), compute-unit cost, and program logs. Modes: action=transfer (native SOL or SPL token transfer — from, to, amount, optional token_mint), action=program_call (arbitrary instruction — program_id, accounts, instruction data), action=sellability (HONEYPOT check — simulate moving an SPL token out of a holder and report if it is frozen / non-transferable), or pass a fully-serialized transaction (transaction_base64) to simulate it as-is. Read-only: never signs, never broadcasts, never moves funds. Not a guarantee the real transaction will behave identically — reflects current chain state. Not financial advice.
