A cat you have to mine.
Mine it with everyone else.

HashCats has no allowlist and no supply cap — the only way in is to find a hash under the network target. HashCatsBot runs the hardware that does it. Deposits are open: send ETH to the published vault, hold shares in the address that mines, and redeem at net asset value whenever you want.

No GPU, no wallet extension for mining, no allowlist. Minimum 0.05 ETH, 8% of realised proceeds, and nothing charged on the way in or out.

Send ETH, see your shares

One transfer to the published vault. Your deposit is confirmed against the chain over RPC, your shares are the ETH you sent, and your slice of the pool is that over everyone else’s — all of it recomputable from the explorer.

Deposit ETH

A plain value transfer on Robinhood Chain. No approval, no message to sign, no contract call.

Pool vault address

Check it against what your wallet shows before you confirm. It is the only address the pool accepts, and the only one this page can send to.

ETH

Minimum 0.0500 ETH. This deposit issues 0.1000 shares — one share per ETH contributed, so your slice is your ETH over everyone’s ETH.

We will never ask for a seed phrase, a private key or a token approval, and we will never message you an address. ETH sent here sits in the operator’s custody: the vault is an ordinary wallet, not a contract that can force a redemption. Size your deposit accordingly.

These figures come from us: the rig mines into its own wallet and the cats are consolidated into a holding wallet, and neither address is published. Everything the pool itself holds is a chain read — it is in your position above, and on the vault at any block you choose.

Proof

Don't trust us. Read the chain.

Our rig has mined 205 cats and that position has collected 17.79 ETH in rent — figures we report, because the wallets behind them stay private. Everything else here is a read you can repeat yourself: what HashCats has paid its holders since epoch 0, what individual addresses have earned, what a cat from each epoch has returned, and whether minting is worth doing today.

What HashCats has paid out so far

Cumulative totals for the whole collection since launch, not for this pool. 65% of every mint price is split across the cats alive at that moment, and holders have been claiming it since epoch 0 — this is the mechanism the pool buys you a slice of.

Is minting worth doing right now?

Winning a race does not oblige anyone to mint the cat. So the fleet mints only when the better of the two legs clears the mint price, and the gate is a live number rather than a promise.

Why pool at all

Three facts about HashCats that make solo mining a bad trade

None of this is our opinion — it falls out of how the contract works, and every number below is read from the live monitor.

Hashpower cannot be aimed at your wallet

The proof-of-work preimage contains the miner's own address, so no one can mine a cat into an address they don't control. That is why a pool has to hold the cats and give you a share, rather than mining straight into your wallet.

Most solutions arrive too late

A cat goes to whoever lands the hash first; everyone else pays gas for nothing. One GPU on its own eats that loss rate alone. A pool spreads it across every depositor.

0 solutions lost in the last 24h — 0% of a win, for 0 ETH of wasted gas

Every epoch doubles the entry price

The mint price follows a fixed curve and doubles at each epoch boundary. Buying in later means paying more per cat, so the timing of when capital is working actually matters — and we publish the curve rather than hiding it.

0.1637 ETH now → 0.3275 ETH next epoch

Mechanism

Six steps, and nothing hidden between them

Deposits fund the contract's mint price and gas. We fund the hardware. What comes back is split by share, and the fee only ever applies to money actually realised.

  1. 01

    You deposit ETH

    Send ETH on Robinhood Chain to the published pool vault — a plain transfer, no approval and nothing to sign — and receive one share per ETH. Minimum 0.05 ETH. No lock-up, no deposit fee.

  2. 02

    We point hashpower at the collection

    HashCats has no allowlist and no supply cap: a cat is minted by finding a hash under the network target. Our GPUs do that work. You are never charged for the fleet — that is what the performance fee buys.

  3. 03

    Your ETH pays only the contract

    Deposits cover the epoch mint price and gas — including gas forfeited on races we lose. Nothing else is drawn from the vault.

  4. 04

    Cats are worked for yield, then settled

    Every cat we win is routed to whichever leg pays more: burn it inside its epoch for the full 1 000 $HASH, or hold it and collect the ETH rent that 65% of every later mint pays to live cats.

  5. 05

    Proceeds land back in the vault

    Realised ETH raises the value of every share. We take 8% of realised proceeds and nothing else — no management fee, no fee on deposits or withdrawals.

  6. 06

    Redeem whenever you like

    Burn shares to withdraw ETH at net asset value. A fifth of the vault is held liquid so ordinary redemptions settle immediately.

The squeeze ahead

Mint cost doubles every epoch while the burn reward stays fixed at 1,000 $HASH. Holding the $HASH price flat, the burn leg goes negative quickly — so the honest question is not “what does it yield” but “how far must $HASH move to keep up”. The offsetting force is real: 30% of every mint price is spent buying $HASH back.

Pool capacity

What the fleet can actually deploy

Because difficulty retargets to hold a fixed cat pace, a pool is limited by hashrate rather than by how much ETH it has taken in. So the deposit ceiling is a published number, not a marketing one.

Risks

The ways this loses money

A deposit page that only lists upside is not telling you enough to decide. These are the real failure modes, in the order we think they matter.

RISK 01

Cost doubles every epoch

The mint price follows 0.00016 x (2^epoch - 1) ETH. It doubles at every epoch boundary while the burn reward stays fixed at 1 000 $HASH, so the burn leg only survives if $HASH appreciates roughly in step. We show the exact breakeven.

RISK 02

Lost races cost real gas

Mining is a race settled first-come. A solution that arrives second is dead and the gas is gone. The network's live loss rate and the ETH it wasted are on the network page — we do not net it out of anything we show you.

RISK 03

$HASH is thin

The burn leg ends in a sale into one pool. Selling size moves the price against us, and the quoted margin already includes that slippage at the size we would actually trade.

RISK 04

The collection ends

There is no supply cap — what stops HashCats is work. Simulation puts the practical end at 17 000-20 000 cats. Mining revenue stops there; rent on cats still alive does not.

RISK 05

Cat inventory is not liquid

Unsold cats are marked at a conservative floor, never at mint price. If redemptions exceed the liquid buffer they are queued and served as inventory is worked down.

RISK 06

You are trusting an operator

Shares are an accounting claim on a vault we control. That is a custody risk and no amount of dashboard removes it. Verify the vault on the explorer, and size your deposit accordingly.

FAQ

Questions worth asking before you deposit

Do I need a GPU?

No. That is the whole point. The fleet does the hashing; your deposit only ever pays the contract's mint price and the gas that mining consumes.

Why can't you just mine into my own wallet?

Because the miner's address is hashed into the proof of work. A solution found for our address is only valid for our address, so cats have to land in a vault we control. Shares are how you own a slice of it, and the vault is public on the explorer.

What do you charge?

8% of realised proceeds — rent we actually claim and $HASH we actually sell. There is no management fee, no deposit fee, and no withdrawal fee. If the pool realises nothing, we are paid nothing.

How are shares issued?

One share per ETH you send the vault. Your slice of the pool is your contributed ETH over all contributed ETH — and because both are just inbound transfers to a published address, you can recompute your own share on the explorer. Redemptions are valued at net asset value: liquid ETH, plus $HASH net of the slippage selling it would cost, plus unsold cats marked at a conservative floor rather than at what we paid to mint them.

How do I know my deposit counted?

A deposit is one plain ETH transfer — no approval, nothing to sign. We treat it as settled at 12 confirmations, read over JSON-RPC rather than from an explorer, so an indexer outage cannot make real ETH look missing. Your ETH, your shares and every transaction hash appear on the deposit page the moment the chain has them.

Can I withdraw whenever I want?

Yes. 20% of the vault is held as liquid ETH so ordinary redemptions settle straight away. If redemptions ever exceed that buffer they are queued and filled as cats and $HASH are worked down — we would rather queue you than dump inventory into a thin market and charge everyone for it.

Why is there a deposit ceiling?

Difficulty retargets to hold a roughly fixed rate of new cats, so extra ETH does not buy extra cats — it just sits idle and dilutes the people already in. We publish a ceiling tied to what our hashrate can actually deploy, and we would rather turn deposits away than take money we cannot put to work.

What happens when the collection runs out?

There is no supply cap; what ends HashCats is work. Simulation puts the practical end at 17,000-20,000 cats. Mining revenue stops there. Rent on cats that are still alive does not, and the vault would then wind down to ETH.

Is this affiliated with HashCats?

No. HashCatsBot is an independent pool. We read the same public monitor the official stats site reads, and we are not endorsed by or connected to the HashCats team.

What is the smallest useful deposit?

0.0500 ETH. For scale, one cat currently costs the pool 0.1637 ETH all-in, so a minimum deposit is a meaningful fraction of a cat rather than a rounding error.

Bring the ETH. We’ll bring the hashrate.

Opening capacity is 98.208 ETH, sized to what the fleet can actually deploy. Minimum 0.0500 ETH, 8% of realised proceeds, nothing on the way in or out.

Deposits go to one published address on chain 4663 as a plain transfer — no approval, no signature. Shares are an accounting claim on a vault the operator custodies, and the vault’s whole position is on the explorer.
