Giveaway Determination Types
Determination type controls how a winner is selected and when. Pick the mode that matches your fairness and operational model.
Type 1
Provider Determination
Provider manually declares a winner passport ID with an on-chain transaction.
Type 2
Self Determination
Provider triggers on-chain random winner selection via contract logic.
Type 3
Auto Self Determination
Requires an end time. After end, your automation system can call auto-draw to finalize winner selection on-chain.
Time Windows
- Start and end are optional. Use `0`/empty for no bound.
- If both are set, end must be after start.
- Type 3 (auto self determination) requires an end time.
Handshake Option
If enabled, the winning passport holder confirms receipt on-chain. This gives providers and entrants auditable delivery confirmation.
At creation time you can also choose who pays confirmation gas: entrant pays (winner submits confirmation) or provider pays (provider submits `confirmReceiptByProvider`).
