Mine The Depths

Mintegra mints gemstone NFTs through open CPU + GPU proof-of-work mining on Robinhood Chain. No whitelists. No insider allocations.

Mine The Depths

Mintegra mints gemstone NFTs through open CPU + GPU proof-of-work mining on Robinhood Chain. No whitelists. No insider allocations.

How it works

Your browser solves a Keccak-256 proof-of-work. You commit the winning hash on Robinhood Chain at the current epoch price, the hash reveals your mineral, depth and rarity, and you can stake the NFT to earn dividends.

10 epochs · 5,550 gemstones

555 NFTs per epoch. Price starts at 0.0001 ETH and rises 0.0001 each epoch, up to 0.0010 ETH. The next epoch starts the instant the 555th mint lands. 70% of every mint goes to stakers, 30% to the treasury.

Holder Benefits

Stake your NFT (never ETH) to earn a share of the dividend pool, weighted by rarity. Unstaking returns your NFT and automatically pays your pending dividends. Secondary sales carry a 10% creator royalty (EIP-2981).
