Rockstock Hood is an NFT GameFi protocol on Robinhood Chain (an Arbitrum L2, gas paid in ETH) combining rune-stone forging, NFT staking, and a built-in marketplace. Each pull burns 20,000 $ROCKSTOCK tokens (sent permanently to the 0x…dEaD address) and mints 1 of 13 tier rune-stone NFTs (capped at 10,000 total supply), plus an instant tier-based NVDA reward from the reward pool (hard-capped at 0.1% of the pool per pull). Staked stones earn a pro-rata, weight-based share of 20% of the tax inflow per minute; the remaining 80% accumulates as a permanent reward-pool buffer. Stones can also be listed on the built-in marketplace at a fixed NVDA price (5% fee routes back into the pool). All logic settles atomically on-chain.
