PancakeSwap Prediction

Certifying

The fully on-chain venue: every 5-minute prediction round on BNB, BTC and ETH with lock and close oracle prices, and every individual wager and claim as a chain event — exact wei amounts, block numbers and transaction hashes. Zero-bet rounds are proven against the contract itself, not assumed.
