Verify Solana events.Then act.

Check the evidence before a log becomes a payout, a reward, or an update.

Verify a transaction Read the docs

Finalized evidence. Explicit outcomes. Shareable receipts.

A log is a signal.
Evidence is the deciding factor.

The event exists in the logs. That does not make the transaction successful.

Rejected

No reward should follow.

EventSeal rejects failed transactions, even when they emitted the expected event.

Supply your trusted program ID and event discriminator. EventSeal checks them against finalized evidence, independently of discovered candidates.
