Tony Hawk Tuck-Knee First-Sale Buyers Raffle

2 min readMay 24, 2021

The first buyers of the 20 Tuck-knee were eligible to enter in a raffle for a Tony Hawk signed skateboard.

As a blockchain company, the raffle was of course executed with a smart contract on the Ethereum network.

The contract is pretty simple and leverages Chainlink’s VRF to randomly select a winner. The contract code is verified and can be read here. The seed for the randomizer function was also chosen with a python random call:
