Cadastra takes real things that earn money in the real world, such as a rooftop solar array, an irrigated field or a cold storage bay, and turns a share of each into something you can hold, operate and trade on-chain. You look after it, it produces income, and you can cash that income out.
Cadastra is not a game about imaginary land. Everything in it points at a real object that a real person maintains and that earns real money.
Solar arrays, farmland, cold storage, micro-hydro, warehousing. Each one is valued by an appraiser, and that valuation is written on-chain where anyone can read it.
A deed is a token that represents a slice of one of those assets. It carries the asset's appraised value, its yield, and a fingerprint of the signed document behind it.
Put a deed to work and it produces GRIT continuously. GRIT is the only token here, and it trades against APTM, the coin of the Apertum network, whenever you want out.
Think of it as a title card for a share of a working asset. It is yours, it lives in your wallet, and unlike a game item its value is anchored to something that exists and produces income. Every deed carries the same set of facts, all readable on-chain:
| Asset class | Solar array, farmland, cold storage, micro-hydro or warehouse |
| Appraised value | What the share is worth, in US dollars |
| Net yield | What it earns per year, as a percentage |
| Jurisdiction | Which country the asset sits in |
| Attestation | A fingerprint of the signed document behind it |
| Level and XP | How far it has been upgraded, which raises its output |
Anyone can claim a token represents a solar farm. The attestation is a fingerprint of the document an appraiser actually signed. If the published document changes by even one character, the fingerprint stops matching, and anyone can check that for themselves.
It does not make dishonesty impossible. It makes it checkable, which is the most any on-chain system can honestly offer about an off-chain object.
Earning is not a lottery and it is not fixed by us. It is calculated from the real numbers on your deed, second by second, for as long as you keep it working.
A $5,000 share of a solar array paying 8% a year, held for a full year:
| Situation | What you get | Why |
|---|---|---|
| Staked, serviced, brand new | 400 GRIT a year | $5,000 × 8% |
| You let servicing lapse | 200 GRIT a year | Output halves until you service it |
| Upgraded once | 460 GRIT a year | Each level adds 15% |
| Fully upgraded, level 10 | 1,000 GRIT a year | Ten levels add 150% in total |
| Sitting in your wallet, not staked | nothing | A deed only produces while it is working |
Your GRIT builds up continuously and you claim it whenever you like. There is no lock-up on earnings and no minimum.
Left alone, a deed slowly stops paying properly, just like a real asset nobody maintains. The interesting decisions are about how you spend the GRIT you earn.
Every deed has a service window of 30 days at a time. Let it run out and output drops to half until you pay for maintenance in GRIT. You can pay several periods in advance and forget about it.
Each level permanently raises output by 15%, up to level 10. Upgrades cost GRIT and experience points, and XP only comes from missions, so you cannot buy your way up.
Commit a deed to a timed job such as a grid balancing window, a harvest or a cold-chain haul. It is locked for the duration, pays out GRIT and XP at the end, and the payout varies between 70% and 150% of the advertised amount.
Owning a deed and operating one are separate things. That matters, because owning a share of a real asset comes with verification requirements, and operating one does not.
| Buy a deed | Lease a deed | |
|---|---|---|
| Identity check | Required, because you hold the asset claim | Not required |
| What you pay | A one-off price in GRIT | Rent in GRIT for a fixed term |
| What you get | The deed itself, and all of its output | The right to operate it, and most of its output |
| Can you play? | Yes: service, upgrade, missions | Yes: service, upgrade, missions |
| When it ends | Never, unless you sell | When the term runs out |
| Best for | Holding for the long run | Trying the game, or playing without paperwork |
Before you take a lease, the app shows you what you should expect to clear over the whole term after the owner's share and the rent. If that number is negative, the offer is a bad deal and it says so plainly.
GRIT is the only token in Cadastra. You earn it by operating deeds, you spend it on servicing, upgrades, mission fees, buying deeds and paying lease rent, and you can sell it for APTM, the native coin of the Apertum network, at any time.
Only two sources, and both are fixed in the contract:
Supply is capped permanently at one billion. A tenth of that was created once at launch and set aside purely to make the market work, so people can buy and sell without huge price swings. No more can ever be created beyond the cap.
Every one of these burns it permanently:
That last one is the important one, and it is what the next section is about.
When the real assets earn money, the operator converts that income to APTM and sends it into the protocol. It is split three ways, automatically, and you can watch every deposit happen on-chain:
If you have never used a wallet before, the first two steps are the only unfamiliar part.
Install MetaMask or any wallet that works with Ethereum-style networks. It is a browser extension that holds your account. Write down the recovery phrase it gives you and never share it with anyone, including us.
Cadastra runs on the Apertum network. Open the app and it will offer to add the network to your wallet in one click. You will need a little APTM to pay network fees, which are very small.
Everything in Cadastra is priced in GRIT, so this is your entry ticket. Buy it with APTM directly in the app, in the market panel.
Leasing is the fastest start and needs no verification. Browse the lease market, check the expected return the app shows you for the term, and take one. Or buy a deed outright if you want to hold it.
Staking starts production immediately. After that: claim your GRIT when you like, keep it serviced, run missions for XP, and spend XP on upgrades to raise output.
We would rather you understand the downside now than discover it later. None of this is unusual for a project like this, but all of it is true.
You earn GRIT, and what it is worth depends on what people will pay for it. The income from the real assets supports that price, but nothing guarantees it. Do not treat earnings as a fixed amount of money.
These are solar panels and cold rooms, not a yield farm. The underlying assets pay single-digit to low-double-digit percentages a year. Anything promising far more than that is not doing what we are doing.
A mission pays between 70% and 150% of its advertised amount. Your deed is locked for the duration and the entry fee is spent whether or not you like the result. It never puts the deed itself at risk.
A deed's value and yield are written on-chain by a trusted role, and those numbers drive what you earn. The signed attestation makes that work auditable, but it is a role that has to be trusted to be honest.
Smart contracts can have bugs. Start with an amount you would be genuinely relaxed about losing, get comfortable with how everything behaves, and scale up from there.
Owning a share of an income-producing asset is treated differently from country to country, which is why ownership requires verification and leasing does not. Check what applies to you.
You need a wallet and a few minutes. If you can install a browser extension and copy a recovery phrase onto paper, you can use Cadastra. The app explains what each action does before you confirm it, and shows the expected result in plain numbers.
Enough GRIT to lease a deed, plus a small amount of APTM for network fees. Leasing is deliberately the cheap way in, because you are renting the right to operate for a fixed term rather than buying a share of the asset. Prices are set by the people listing, so browse the lease market in the app to see the current range.
A deed represents a share of a real appraised asset, and the appraisal and supporting document fingerprint are on-chain for you to check. What that means legally depends on the structure behind each asset and on where you live, which is exactly why buying a deed requires identity verification and leasing one does not.
Not through gameplay. Missions can pay less than advertised, but nothing in the game takes a deed away from you. The usual crypto rules apply though: if you lose your wallet recovery phrase, nobody can recover your account for you.
Your deed keeps producing, but once its service window lapses it produces at half rate until you pay for maintenance. Nothing is lost or taken. It just underperforms. You can pay for up to a year of servicing in advance if you would rather not think about it.
Claim your GRIT, then sell it for APTM in the app's market panel. There is no lock-up, no waiting period and no approval step. What you receive depends on the market price and on how much you are selling at once. The app shows you the exact amount before you confirm.
Leasing gets you playing immediately with no verification and a smaller outlay, but it ends when the term does and you hand back a share of what you produced. Buying costs more up front and requires verification, but the deed is yours, keeps its levels and XP, and can be sold later. The app shows the expected return on every lease offer so you can judge each one on its numbers.
Whoever is selling it. There is no official price. Every listing in the app shows the deed's appraised value, its yield and how much it produces in a year against the asking price, so you can judge whether a price is reasonable rather than guessing.
The native coin of the Apertum network, the blockchain Cadastra runs on. You need a small amount to pay transaction fees, and it is what you receive when you sell GRIT.
The app is free to open and browse. Connect a wallet only when you actually want to lease, buy or stake something.
