Mining is live
Open the official miner on Robinhood Chain mainnet, chain 4663. Check the network and contract addresses. RC1 and RC2 are historical testnet releases, not the current production network.
Every accepted proof mints one Hunter NFT, up to 5,000 lifetime Hunters. Burning a Hunter does not reopen a minting slot. Mining does not mint or pay HUNTER tokens.
Start in the browser
- Connect MetaMask on Robinhood mainnet.
- Create or restore a separate encrypted mining wallet.
- Download its backup and keep the passphrase safe.
- Transfer mainnet ETH to that mining address and set a run-wide gas limit.
- Start mining. The hashrate and nonce counter show the search in progress.
- Wait for a confirmed transaction and NFT ownership before treating a result as a discovery.
The mining wallet submits proofs and receives the NFT. Your connected MetaMask wallet funds gas and signs optional Mining Power actions; it is not automatically the NFT owner. A browser wallet and a CLI wallet are separate unless explicitly restored from compatible recovery material.
The challenge number is shared by all miners. It is not your NFT count. A challenge can advance when another miner wins or when an expired seed is refreshed. Keep the page open and the device awake to continue browser mining. Stop prevents new signing; a submitted transaction may still settle.
Optional Mining Power
HUNTER is live as a separate fixed-supply token. You do not need it to mine at base power.
To add power, approve and lock HUNTER from your funding wallet, then assign it to the exact mining-wallet address. Loose tokens and HUNTER credited to an NFT’s reserve do not increase mining power.
| Assigned HUNTER | Assigned multiplier |
|---|---|
| Below 1,000,000 | 1.00× |
| 1,000,000 | 1.50× |
| 3,000,000 | 2.00× |
| 7,000,000 | 2.50× |
| 15,000,000 or more | 3.00× maximum |
An assignment made during a challenge takes effect at a later challenge snapshot, not midway through that challenge. The assigned multiplier can therefore differ from the power used for the current search. The custody rules include a 12-accepted-proof wait before unassignment; it is not a 12-minute timer.
Timing and costs
The configured target cadence is one accepted proof per 50 parent blocks, with retargeting every 144 accepted proofs. The approximately month-long collection model is a population scenario, not a deadline or a promise to any wallet. The 12-second parent-block model anchor is about 34.72 days for 5,000 proofs before other effects.
Mining is competitive and probabilistic. Another miner can win first, a proof can become stale, and a submitted transaction can revert. Hashrate is search speed, not guaranteed income. Mainnet gas uses real ETH.
The browser’s run limit caps authorised gas exposure for that run. It neither funds the wallet nor sets your chance of winning.
Command-line mining and AI agents
CLI v0.3.0 mines on the system upgraded on 28 Sep 2026; v0.2.3 cannot. Stake 1M HUNTER tokens to the CLI wallet in the app before mining. See CLI setup and release status.
The v0.1.0 binary is legacy. The standalone repository is public, and each v0.3.0 platform package pins its matching binary, checksums and mainnet profile.
The old HUNTER boost (MiningPowerCustody) is withdraw-only since the 27 Sep 2026 pause: HUNTER assigned there no longer affects mining. Withdraw it from the app at any time.
