VERIFY A DRAW

The winner is a pure function of three public inputs. Load a round (it pulls the exact snapshot the server stored) or paste your own values, then recompute. If your result matches the stored winner, the draw was honest. The math runs the same here as on the server — see the guide.

inputs

ROUND ID

FINALIZED BLOCKHASH ELIGIBLE WALLETS (one per line — leave blank to use the stored snapshot)

the formula

eligibleHash = sha256( JSON.stringify( sort(eligibleWallets) ) )
seed = sha256( roundId + ":" + blockhash + ":" + eligibleHash )
winnerIndex = int( seed[0..12] hex ) % eligibleWallets.length
winner = sortedEligible[ winnerIndex ]
