BRAIN OIL / GAME DESIGN
A Field and Rig NFT concept for Robinhood Chain. This is a design description, not a guarantee of returns or an audit.
Network
Robinhood Chain (chain ID 4663). RPC: https://rpc.mainnet.chain.robinhood.com/. Native asset: ETH. Block explorer: robinhoodchain.blockscout.com.
NFT ownership
An ERC-721 game contract represents seven Field tiers and 15 Rig types. Each wallet can own one Field and up to its tier's rig capacity. Fields cannot transfer while Rigs remain in their original wallet; Rig transfers require the recipient to have a Field with an available slot.
Minting
A starting Field mints for 0.001 ETH. Rig prices rise linearly by type from 0.001 to 0.01 ETH. Field tier upgrades cost 0.0015 ETH per new tier step (tier 2: 0.0015, tier 7: 0.009). The all-ETH model was chosen; fees remain proposals pending contract review and deployment.
Reward pool
Paid mint and upgrade ETH remains in the game contract. Free dev mints add no ETH. When rigs exist, available ETH is gradually allocated to rigs weighted by drill power over a six-day release period. Claims are limited to allocated rewards while the contract is active and funded; the owner can drain all ETH in an emergency.
$BRAINOIL token
The BRAIN OIL token ($BRAINOIL) is planned to launch via Ponsfamily.com. It has not launched yet. NFT minting, Field upgrades, and game rewards use ETH; no token exchange rate or legacy balance conversion is defined.
OpenSea & MetaMask
After a real contract deployment and public token metadata are configured, ERC-721 tokens can be discovered by compatible NFT platforms and wallets. Discovery and marketplace indexing depend on third-party support; neither is automatic before deployment.
Security
The contract source is a draft requiring independent review and testing before real funds are used. No live contract address or completed security audit is claimed.
