Hashcats on Robinhood Chain: How the proof-of-work NFT works—and what to verify

What launched—and what can be independently checked

Hashcats is a newly launched NFT collection that replaces the familiar ‘mint’ button with a proof-of-work search performed in a web browser. The official Hashcats account announced that the project was live at 17:08 UTC on 11 September 2026 after reporting a short delay from its planned 17:00 UTC start. That launch post, the official website and the public chain explorer all point to the same collection contract: 0xCA75DF55Cc9C476DB27a7375D1fc8E794cf80721.

The Robinhood Chain Blockscout explorer labels that address Hashcats, with the symbol HCAT. OpenSea also maps the same address to its Hash Cats collection and identifies it as an ERC-721 contract. These records establish that a collection using this name and contract is active on Robinhood Chain. They do not, by themselves, prove every statement in the project’s economic description or establish that the code is secure.

That distinction is central to this Reddy News explainer. Some facts are directly observable: the contract address, transfers, mint events and the project’s public interfaces. Other points—including how the team expects difficulty, rent, burns and buybacks to influence behaviour—are claims or models published by Hashcats. They should be read as the project’s description, not as an independent promise of performance.

Robinhood Chain is the network, not an endorsement

Hashcats runs on Robinhood Chain mainnet. Robinhood’s own documentation describes the network as a permissionless, EVM-compatible Arbitrum Layer 2 that uses ETH as its gas token. The mainnet chain ID is 4663, its public RPC is rpc.mainnet.chain.robinhood.com, and its explorer is hosted by Blockscout. EVM compatibility means developers can deploy Ethereum-style smart contracts and users can inspect ordinary on-chain activity with familiar tools.

A permissionless network can host third-party applications without making those applications official Robinhood products. Reddy News found no evidence in the reviewed official material that Robinhood created, sponsored or endorsed Hashcats. Robinhood also says its chain operates independently from users’ Robinhood brokerage and crypto accounts. The project’s use of the network should therefore not be interpreted as custody, protection, vetting or a guarantee from Robinhood.

How the proof-of-work mining process is designed

According to the project’s technical explainer, the Hashcats miner repeatedly hashes four inputs: the prospective miner’s address, a changing counter or nonce, the proof that produced the previous cat, and a recent block hash. The browser keeps testing combinations until it finds a digest below the contract’s current target. A valid result can then be submitted to the collection contract, which verifies the proof before minting the token.

Each input has a stated purpose. Binding the work to an address is intended to make a copied solution unusable for a different recipient. Including the previous cat’s work links one successful proof to the next. Including a recent block hash gives the work a limited lifetime; if the reference becomes too old, or another cat changes the required previous work, a locally discovered solution can become stale before confirmation.

The project says the target retunes every eight cats and also reacts to recent minting pace. More leading zero bits represent greater expected work because each extra bit roughly halves the chance that a random attempt will qualify. The official dashboard was showing a 37-bit target and an estimated 5.15 GH/s network rate when checked. The hashrate is an estimate derived from target and observed pace, not a meter that sees every unsubmitted hash.

Why this is not a conventional free mint

Calling the process ‘mining’ does not mean the NFT is free. A participant first spends computing effort searching for a proof. A successful submission also carries the epoch’s formula-derived ETH entry amount and the network gas fee. At the publication snapshot, the official interface quoted 0.16368 ETH for the next cat in epoch 10 and showed 0.32752 ETH for the following epoch.

Hashcats says it had no allowlist, presale or team allocation and does not provide an ordinary one-click mint button. Those design choices can reduce some common launch advantages, but they do not eliminate competition. Faster hardware, better code, lower latency and the ability to pay the required ETH can still affect who successfully submits work. The project’s interface itself warns that laptops are slower and that dedicated GPUs may perform better.

A browser can also stop, crash or lose a race. A proof may be technically valid when found but unusable by the time it reaches the chain because the anchor aged out or another mint changed the previous-work input. Anyone evaluating the system should count electricity, hardware wear, failed attempts, stale work, gas and the entry amount—not only the visible NFT.

The 16,376 ‘wall’ is not a fixed supply cap

The number 16,376 appears prominently on the official dashboard, which reports how many cats remain ‘before the wall’. It should not be described as a hard maximum. The project’s own explainer says there is no fixed supply cap. Instead, 16,376 is the point at which the difficulty and economic rules become much harsher.

Before the wall, the entry amount rises through epochs. The project says that after the wall, work requirements increase quadratically with additional supply while the entry price continues to climb. The intended effect is to make later cats progressively harder and more expensive to produce rather than stopping minting at one exact token number.

Hashcats says its simulations suggest a practical ceiling somewhere around 17,000 to 20,000 cats. That range is a model supplied by the project, not a contractual cap or a forecast that Reddy News can verify. Changes in hardware, participation, ETH prices, fees and user appetite could produce a different outcome.

What the project says lives on-chain—and what remains unverified

Hashcats says each cat’s image, traits and palette live in contract storage, with the final artwork assembled from on-chain data rather than relying on IPFS, an API or a conventional image server. Blockscout token pages and OpenSea item pages display individual cats tied to the collection address, which supports the basic observation that token-level data is being served from the contract ecosystem.

‘On-chain’ is a storage description, not a security rating. Reddy News did not locate a linked independent smart-contract audit in the official website, documentation, X article, Blockscout page or public project GitHub reviewed on 13 September. The public GitHub organisation exposed branding and analytics-related repositories, but not an obvious repository containing the collection contract’s source code.

Readers should therefore avoid treating an attractive explorer page, visible bytecode or marketplace listing as proof of a completed third-party audit. The correct contract address must still be checked character by character through more than one official source, especially because look-alike collections, fake social accounts and phishing links are common around new NFT launches.

A time-stamped snapshot of the first two days

At approximately 9:30 am India time on 13 September 2026, the official Hashcats statistics dashboard showed 8,855 cats mined, or 54.1% of the 16,376 tokens that it counts before the wall. It recorded 5,747 cats alive, 3,108 burned and 1,351 holder addresses. The dashboard also showed 6,085 mints and 2,346 burns in its displayed daily window.

The same snapshot reported 555.912 ETH paid for mints, 222.361 ETH of rent claimed across 39,438 claims and 125.613 ETH of rent marked unclaimed. Its proof-of-work panel displayed a 37-bit target, a recent pace of about 27 seconds per cat and an estimated 5.15 GH/s hash rate. These readings were moving while this article was being prepared and may already be different.

The numbers come from the project’s event-driven dashboard, which links recent entries to public Blockscout transactions. That makes individual events inspectable, but it does not convert the dashboard into an independent valuation service. Address counts are not the same as verified people, protocol balances are not personal returns, and a fast launch period does not establish durable demand.

Rent, burns and the $HASH token—without the sales pitch

Hashcats adds a second layer of mechanics around the NFT. The project says part of each mint payment is allocated as rent to earlier living cats, while another portion flows to a hook and pool. A living cat can claim accumulated rent; burning a cat destroys the NFT and creates $HASH under the contract’s epoch rules. The token contract shown by the official dashboard is 0xCA75082b85bb7Bec8325d513F615b16BDa260020, while the hook and pool address is 0xCA757986E932BC55776492Cca0b413E9b3D02aCC.

The dashboard says the pool charges a 5% fee on $HASH swaps and that part of specified inflows enters a buyback queue. At the snapshot, it reported 158.981 ETH spent buying and burning 1,574,519 $HASH, with 50.176 ETH waiting in the queue. It also displayed a virtual ETH reserve and a per-block spending cap designed to limit the size and price impact of a buyback.

None of those mechanisms guarantees profit. Rent depends on protocol activity and claim rules; buybacks depend on actual inflows, contract execution and market liquidity; and burned supply does not ensure rising demand or price. The project’s own dashboard notes that an unspent queue does not predict when the balance will be used. A fee, royalty or buyback is a programmed flow—not a promise that holders will recover costs.

There is also an economic feedback loop worth understanding. More mining can create more payment flows and potential rent, but it can also increase competition, raise the epoch entry amount and move the collection toward the wall. Burning reduces the number of living cats while creating $HASH, but it permanently gives up the NFT. These relationships are complex and should be evaluated as smart-contract mechanics, not as a simple yield product.

The marketplace snapshot is not a price forecast

OpenSea’s collection page was displaying a floor near 0.1619 ETH, roughly $3.1 million in total volume and 464 listed items when checked for this report. OpenSea’s embedded collection metadata also identified a 5% optional creator-fee setting and showed the collection as unverified at that time. All of these are platform-specific, rapidly changing observations.

A displayed floor is usually the lowest visible asking price, not proof that a sale will occur there. Total volume describes historical marketplace activity, not the value available to every holder. Listings can be cancelled, liquidity can disappear, fees can change and wash or self-directed activity can distort impressions of demand. Cross-market prices may differ, especially for a collection that is only days old.

For that reason, Reddy News is not publishing a price target, expected return or recommendation to mint, buy, hold or sell. The useful question is whether readers can verify the contract, understand the mechanism and accept the full loss scenario before interacting with any link or wallet prompt.

The risks that deserve more attention than the artwork

The first risk is straightforward: NFTs and related tokens can lose most or all of their market value. A new collection can attract intense activity for a short period and then become illiquid. The existence of rent, royalties, trading fees or buybacks cannot remove price risk, counterparty behaviour or the possibility that demand fades.

The second risk is operational. Proof-of-work consumes computing resources and electricity, while a stale result can produce no mint. Submitting a valid proof still requires ETH for the entry amount and gas. Wallet signatures can expose users to malicious approvals, fake contract addresses or deceptive websites. Seed phrases and private keys should never be typed into a site, sent to another person or shared with anyone claiming to provide support.

The third group covers technology and infrastructure. Smart-contract bugs, unaudited code, front-end compromise, bridge failures, RPC outages, chain congestion and explorer or marketplace errors can all affect access or asset safety. Robinhood Chain’s EVM compatibility does not make every contract on the network safe. Users are also responsible for checking whether digital-asset activity is permitted where they live and for understanding any tax or reporting obligations.

Only the official domain, hashcats.fun, and the contract address published there should be used as starting references—and even those should be cross-checked independently. Reddy News has not connected a wallet, run the miner or submitted any on-chain transaction for this report. This article is factual news coverage, not financial, legal, tax or technical security advice.

What to watch next

The most useful next evidence will come from the chain rather than promotional posts: the rate of successful mints, how quickly the target retunes, how many cats remain alive, whether holder concentration changes, and how much of the stated rent and buyback activity is visible in linked transactions. The approach to the 16,376 wall will also test the project’s model in conditions that did not exist at launch.

Security disclosure is equally important. A public, reproducible contract source and a credible independent audit would allow specialists to test more than the interface description. Until then, readers should separate ‘the contract accepted this transaction’ from ‘the entire mechanism has been independently reviewed and found safe’. Those are not the same claim.

Hashcats is notable because it combines browser proof of work, an on-chain generative collection and interconnected NFT-token economics on a new public network. Novelty is a reason to examine the design carefully, not a reason to suspend scepticism. Reddy News will update material facts if the project publishes verifiable contract documentation, an audit or significant changes to its rules.
