Welcome to Grimkin. Bring a lantern.

THE COLLECTION

What a Grimkin is

A Grimkin is a pixel monster drawn on a 128 × 128 grid: crowned, hooded, armoured or robed, always slightly menacing. There are exactly 1,499 of them, and that number never grows.

Every Grimkin comes from one of 15 master designs. Each design is a complete portrait, with outfit, headwear and accessories drawn together so they fit. Around that, every edition gets its own skin colour (11 options), gear palette (6) and background (8), so no two of the 1,499 are the same.

The designs are split into five tiers with fixed quotas. The tier is printed in each Grimkin's traits, and in the Grim Mine it sets how fast that Grimkin mines.

THE MINT

How to get one

Grimkin mint as a drop on OpenSea, on Robinhood Chain. Robinhood Chain is an Ethereum layer-2 network, so you pay mint price and gas in ETH. Token numbers run from #1 to #1,499.

Until the reveal, every Grimkin shows the same sealed image: a crowned silhouette under the stars. Your Grimkin's art and traits appear when the mint is complete.

FAIR LAUNCH

Reveal plan — launch blocked

In many collections, rarity rankings leak before or during the mint, and bots grab the rare tokens. The intended reveal will prevent choosing token assignments, but its authenticated randomness integration is not implemented. Mint, reveal publication and mine opening remain blocked.

We never publish rarity rankings

There is no rarity rank or rarity score anywhere: not on this website, not in the token metadata, not in any file we publish. The tier is a visible trait; rankings are not.

The art is locked before the mint opens

All 1,499 images are fingerprinted, and one combined fingerprint, the provenance hash, is published and written into the contract before the first mint. After that it cannot be changed:

716a21ac782a3f8e4992b2a17ef7266b0675116f18065f72730023ab1fea41c9

Anyone can check it: take the SHA-256 of each image file in edition order from 1 to 1,499, join the 1,499 hashes into one string, and hash that string again with SHA-256. If any image had been swapped, the result would not match.

Public randomness decides who gets what

After the mint closes, a random starting index is drawn from a public source of randomness that nobody controls. Token #t then shows edition ((t − 1 + starting index) mod 1,499) + 1. Because the index is only known after every token has been minted, nobody could have aimed for a particular character.

THE WORLD

The Underforge

This website is a cave. It starts on the surface at night, beside a camp fire, a timbered mine entrance and a giant gold crown lying in the grass. Scroll down and you go underground. Your cursor is your lantern; deeper in, the dark closes in and the lantern is what lets you see. Every chamber is a real depth:

1. 0m
   Surface campThe collection, the 15 designs and how the mine works.
2. 120m
   Gallery GrottoEvery character, with filters for tier, design and traits.
3. 340m
   The UnderforgeThe Grim Mine, where you see and claim your GKIN.
4. 520m
   The ForgeUpgrades for the expedition game.
5. 680m
   Record VaultYour expedition journal.

Changing chamber drops you down the shaft, or lifts you back up, while the depth counts past. There is an optional cave soundtrack: room tone, echoing drips, and forge crackle in the deep. Switch it on with the speaker button.

THE GRIM MINE

Your Grimkin mines GKIN

Every Grimkin you hold mines GKIN from the Grim Mine every second, for as long as you hold it. You don't need to stake, lock or send your NFT anywhere. It stays in your wallet and keeps mining.

Rarer tiers mine faster

Claim whenever you like

GKIN builds up by the second. Claim once a day, once a month or at the end of the season: nothing is lost by waiting. The claim panel shows the amount growing live for each of your Grimkin.

Selling? The unclaimed GKIN goes with it

Mined GKIN belongs to the Grimkin, not to the wallet. If you sell or transfer a Grimkin, whatever it has mined and you haven't claimed goes to the new owner. Claim first if you want to keep it.

Where the GKIN comes from, and why it can't run out

• The pool is funded up front. When GKIN launches, the team buys GKIN and sends it straight to the Grim Mine contract. That deposit is public on-chain.
• The mine only opens if the pool covers everyone. The contract checks that it holds enough GKIN for every Grimkin to mine the whole season at full rate. If the pool falls short even by one unit, the mine cannot open. At the planned numbers that is 466,236,400 GKIN.
• Then the pool is locked. After opening, nobody can change the rate, the tiers or the season, and nobody can withdraw the pool. Only 180 days after the season ends can unclaimed leftovers be moved out.
• The contract cannot create GKIN. It only hands out what it already holds.

THE TOKEN

GKIN

GKIN launches on Pons, a token launchpad on Robinhood Chain:

• Fixed supply of 1,000,000,000 GKIN. Nobody can mint more.
• It trades first on a bonding curve, where the price moves with buys and sells.
• Once the curve fills, GKIN graduates to a Uniswap v4 pool, and that liquidity is permanently locked.
• The team's launch purchase is what funds the Grim Mine pool.

In the open about how the team is funded: the team receives the mint proceeds, OpenSea creator earnings on resales where they apply, and the creator share of GKIN trading fees on Pons.

STEP BY STEP

How to claim your GKIN

1. Go to The mine (340m).The claim panel sits at the top of the chamber.
2. Connect your wallet.The site moves your wallet to Robinhood Chain, or adds the network if your wallet doesn't know it yet.
3. See your Grimkin.Each one is listed with its tier, its GKIN a day and what it has mined so far, counting up live.
4. Press Claim all and confirm in your wallet.This is the only transaction the site ever asks you to sign. You pay a small gas fee in ETH. With more than 100 Grimkin, it is split into several transactions.
5. The GKIN arrives in your wallet.The panel refreshes, and your Grimkin carry on mining.

JUST FOR FUN

The expedition game

Below the claim panel there is a small game. Pick a character, choose one of three routes into the mine, and bring back ORE and crystals. Then spend them at the Forge on a better pickaxe, crystal infusions and a bigger satchel. Each design has its own ability, so a Tactical Scout moves faster and a Bone Shaman finds more crystals.

The game is separate from GKIN. ORE and crystals live only in your browser, have no value, and do not affect what your Grimkin mine.

WHAT HAPPENS WHEN

The road ahead

1. Mint on OpenSea.The provenance hash is published and locked into the contract before the first mint.
2. Reveal.After the mint closes, public randomness sets the starting index and every Grimkin's art and traits appear.
3. GKIN launches on Pons.The team's launch purchase is sent to the Grim Mine.
4. The Grim Mine opens.The contract checks the pool covers the full season, then locks it. Every Grimkin starts mining.
5. The season runs.Planned: 730 days. Claim any time; after the season ends you can still claim what was mined.

STAY SAFE

Before you connect a wallet

• Use only links from the official Grimkin channels. Contract addresses will be published there: ANNOUNCED AT LAUNCH.
• Check you are on Robinhood Chain (chain ID 4663) before you sign anything.
• This website only ever asks you to sign a claim. It never asks for token approvals, never asks you to send your NFT anywhere, and never asks for your seed phrase. Nobody from the team will DM you first.
