Smart Contracts & Escrow
The non-custodial financial backbone of Prizee Raffle is the CircleSmartEscrow smart contract deployed on the Arc Network.
Escrow Lifecycle & Player Protection
CircleSmartEscrow enforces transparent, non-custodial custody of all campaign prize pools. When a creator launches a lottery or task bounty, funds are deposited directly into the smart contract and permanently locked until verified draw settlement.
Core Product Guarantees
1. 100% Locked Prize Escrow
- When a round is created, the creator deposits the total advertised prize pool directly into
CircleSmartEscrow. - The smart contract holds the funds in autonomous custody. At no point can platform administrators or third parties divert, rehypothecate, or lock these funds.
2. Automated & Instant Winner Payouts
- Once the target on-chain block is mined and winning numbers are derived, the protocol executes automated smart contract payouts.
- Prize amounts are transferred directly from the contract to each winning player's non-custodial wallet address.
3. Creator Refund Protection
- If a campaign fails to meet its minimum participation requirements or is cancelled prior to ticket sale commencement, the creator can trigger an automated 100% refund.
- Once refunded, the round is permanently sealed, guaranteeing no double-spending or stale rounds.
