Current rules

Robinhood Chain is the user transaction network. Base remains the VRF service side, connected by the specified CCIP flow. The last of 500 collectibles initiates an asynchronous selection. Selected collectibles receive a 1/6/10 group distribution using 50/30/20 of the funded pool; failed direct transfers remain claimable.

Referral is independent of minting. The direct referrer's active $2/$5/$10 plan sets a 50%/60%/82% share. Upgrades pay the configured price difference and retain the original direct referrer.
