Mine your
Ronin
Use your CPU or GPU to find a proof and mint a Ronin. Each NFT comes with its final artwork.
Start mining
Meet the Ronin
Original pixel art inspired by Japan's seasons,
landscapes and wandering samurai.
Price and difficulty
The first 100 NFTs are free. After that, every 100 mints adds one price step and doubles the work needed on average. Each step is set to about $0.10 at launch. The final 111 NFTs share the highest price, about $1 at launch, and 40-bit difficulty.
| NFT numbers | Difficulty | Mint price | Average search |
|---|
Prices are fixed in ETH at deployment. Dollar amounts are launch estimates and may later exceed $1 as the ETH exchange rate changes. Your wallet shows the exact mint price and gas fee. Gas also applies to failed transactions.
Search times are averages. A proof does not reserve an NFT or a price. Mining uses your device and electricity. Every mint requires proof of work and a mint transaction. Difficulty rises with the number of mints, without a time limit or adjustment for network speed.
Mine a Ronin
Start your search
Choose CPU or GPU and start mining. When you find a proof, review and confirm the mint in your wallet.
Choose how many CPU threads to use. Fewer threads leave more capacity for other tasks.
Start mining to measure your speed and estimate the search time. You can stop at any time.
How it works
Find a proof
Your processor or graphics card searches for a valid Keccak-256 hash. Each new stage doubles the expected work. Faster hardware can try more hashes.
Review the mint
Mining stops when a proof is found. Check the current NFT price and network fee before confirming. A proof does not reserve an NFT.
Confirm your mint
Review the mint price and gas fee in your wallet. The contract checks your proof, then creates the NFT with its final artwork.
Difficulty rises from 30 to 40 bits. Price and difficulty increase together every 100 mints, then stay fixed for the final 111 NFTs.
Before you mint
Read the contract ↗What am I minting?
Ronin Hash is a collection of 1,111 original pixel artworks. Tokens are named Ronin #1 through Ronin #1111. Their images and traits are stored on IPFS. The contract cannot change the metadata or increase the supply.
When is the artwork revealed?
Each NFT links to its final image as soon as it is minted. You do not have to wait for a later reveal. Loading the image depends on IPFS availability and your connection.
How is rarity assigned?
The artworks were shuffled once across all 1,111 token numbers. Every original and its traits are preserved, with rare tiers spread throughout the collection.
The order is fixed and public, so anyone can inspect upcoming artwork. Finding a proof does not reserve a number. The order of confirmed transactions determines which NFT you receive.
How is a mining proof checked?
The contract verifies proof of work tied to your wallet, this collection and the network. Finding a proof does not reserve an NFT. Automated miners can participate; proof of work does not establish that a miner is human.
What does minting cost?
The first 100 NFTs are free. Each following group of 100 adds one fixed ETH price step. The final 111 NFTs share the ten-step maximum. A step is set to about $0.10 at launch, making the final price about $1 at that exchange rate. Its dollar value can change afterward.
You also pay network gas, including for failed transactions. Mining uses computing power and electricity. Payment does not reduce the difficulty or bypass the contract checks.
What can the creator change?
The supply, price steps, difficulty schedule, artwork and creator recipient are fixed. There is no team mint, premint or upgrade function. Mint payments can only be withdrawn to the fixed creator address.
The owner can change or disable the transfer validator used for marketplace royalties. This validator can restrict NFT transfers and compatible marketplaces. The owner can also transfer or renounce contract ownership.
How do the 5% royalties work?
The contract specifies 5% creator royalties through ERC-2981. Marketplaces collect them if they support or enforce the setting. Sending an NFT between wallets does not automatically charge a royalty, and the fee is not charged separately to both sides of a sale.
OpenSea enforcement requires a compatible transfer validator and creator earnings settings. These must be configured after deployment. The royalty setting alone does not guarantee payment on every sale.
Do CPU and GPU miners have the same chances?
Every hash has the same chance of being valid. Faster hardware can try more hashes, so it has a higher chance over the same period. GPU mining needs a browser and graphics driver that support WebGPU. Optimized external miners may be faster than the browser miner.
The fixed difficulty schedule does not guarantee how long minting will last. There is no guaranteed income, resale price or liquidity.
When does a proof expire?
Your proof becomes invalid when your wallet mints or a new difficulty stage begins. There is no separate expiring server permit.
A proof reserves neither an NFT nor its price. A stage change before your transaction is included can make it fail and still cost gas. Work for the first stage can be calculated before a scheduled opening.
When will my NFT appear on OpenSea?
A successful mint creates the NFT in your wallet on Robinhood Chain. OpenSea can show it after indexing the contract and metadata. This may take time. You can then choose a sale price and list it yourself.
Is the collection live?
Public minting is not open yet. Local checks are recorded in the project review. Before launch, the collection still needs public network, direct mint, IPFS and OpenSea checks. It has not received an independent security audit.
Before signing, check the announced network and contract address. This site never asks for your seed phrase or token spending approval.
