// APPROVED DAPP / PERMANENT RECORD

Proof-of-work gemstone NFTs native to Robinhood Chain. Every Mintegra gem is mined through real browser hashing, and miner status is earned only by the wallet that mined it. Epoch 2 is open at 0.0002 ETH until gem #1110.

Mintegra is a proof-of-work gemstone NFT collection built natively on Robinhood Chain (chain ID 4663). Every gem is mined through real Keccak-256 hashing in the browser: no presale, no whitelist, no airdropped gems. The collection has 5,550 gems across 10 epochs. Every mint splits 70% to staked gems by rarity weight and 30% to the treasury, recorded on-chain. Miner status is earned only by the wallet that mined a gem itself; buying a gem on a marketplace does not make a miner. Genesis Miner status belongs to epoch 1 wallets, and the OG Miner window closes at gem #1110. At the time of filing: 581 of 5,550 gems mined, 529 remain in epoch 2, and 406 gems are staked. Mintegra also runs the Assay Desk, a free plain-language contract-reading service for Robinhood Chain, and a public miner record through Zealy.
