Chainlink VRF
Verifiable Random Function (VRF) Oracle
Toyland uses a Verifiable Random Function (VRF) to ensure fairness and transparency in its games. A VRF acts as a Random Number Generator (RNG) that provides outcomes which are verifiable on-chain, ensuring that every result is tamper-proof and provably fair.

VRF Fees
Using VRFs requires significant computational power, and a fee is necessary to resolve RNG requests. Here’s what you need to know about VRF fees:
Fee Payment:
The VRF fee is paid upfront by the user at the time of request.
Gas fees might appear high initially because the total fee can only be determined once the request is made.
Fee Refund:
A large portion of the VRF fee is refunded in the same transaction.
Pending VRF Requests
Occasionally, VRF requests may not resolve immediately. Here’s what happens in such cases:
Pending Requests:
Players can find unresolved VRF requests in their Pending VRF Requests section on their profile page.
Stuck Wagers:
On rare occasions, a VRF request may fail to resolve, causing the player's wager to remain stuck in the game contract.
After 100 blocks, players can click the "Refund" button to retrieve their wager from the contract.
