Check a Solana transaction before signing it (Overwing Preflight) — Call this before signing any Solana transaction. Overwing Preflight simulates the unsigned transaction against the chain as it is now, works out what it would take from the wallet you name (SOL, tokens, and control of its token accounts) and answers allow or refuse against your policy, with every reason. Sign only if decision is "allow". Treat a refusal, an error, or anything else as do not sign. A verdict describes one moment and covers a transaction that lands within about two minutes, so sign and send at once or check again. This tool takes the serialized transaction and a policy; it never…
What Preflight checks and how to call it (Overwing Preflight) — The reference for Overwing Preflight: every policy field, every reason code a refusal can carry, what a verdict does and does not promise, the price, and the terms of the guarantee. Read it once before the first preflight_check. No key needed.
The public record (Overwing Preflight) — Everything Preflight has said and how it held up: counts of verdicts and misses, every miss with what the chain showed, the latest verdicts, and what the guarantee's reserve holds. Read it before deciding whether to rely on Preflight. No key needed.
Report the transaction that landed (Overwing Preflight) — After a transaction that Preflight allowed has landed, report its signature. Preflight reads the landed transaction from the chain and says whether the allow held: not_a_miss, or miss when it took more from the wallet than the policy permitted. The outcome is published. A covered miss is paid to the wallet in the verdict, never to whoever reported it. No key needed.
Read a published verdict (Overwing Preflight) — The public record of one Preflight verdict: its decision, reason codes, the programs the transaction would run, the transaction's digest, our signature, and every landed transaction reported against it. Never the wallet, the amounts or the transaction. No key needed.
