How BlockHaus Uses Polygon
By Tahar Ali, CEO and Founder of BlockHaus | May 06, 2026 | Updated October 08, 2026
The short answer: BlockHaus runs two contracts on Polygon. One is the BLK token. The other is the presale. You pay in USDT on Polygon, the network fee is a few cents, and BLK arrives in your wallet in the same transaction. That is what Polygon does for us.
BlockHaus is a UK property company. We sell BLK, our utility token, to fund buying and refurbishing property, starting in the UK, including London, and in Dubai. The property side happens in the real world, with solicitors and deeds. Polygon is where the presale happens.
What Polygon Is, Without the Jargon
Polygon is a blockchain that works like Ethereum but costs far less to use. It uses the same kind of wallet addresses and the same wallets, such as MetaMask and Trust Wallet. Fees are paid in POL, Polygon’s own coin, which used to be called MATIC.
People often call Polygon a Layer 2. Strictly, the main Polygon network is its own proof of stake chain. Validators lock up POL to confirm transactions, and the network regularly records checkpoints on Ethereum. For a buyer, the practical part is simple. A transaction takes seconds and costs a few cents.
Why We Chose It
The minimum purchase in our presale is $20. On Ethereum itself the network fee alone can cost more than that when the network is busy. On Polygon it is a few cents. A $20 minimum only makes sense on a cheap network.
USDT is easy to get on Polygon. Most large exchanges let you withdraw it straight to the Polygon network, along with a little POL for the fee.
And because Polygon works like Ethereum, the contracts use the same well known standards that wallets already understand. BLK shows up in a normal wallet like any other token.
There is a trade off. Polygon has fewer validators than Ethereum, so it is less spread out. For small purchases, we judged that worth it.
What Runs on Polygon
The token contract (0x5cF704a1F5B5555B7369F4AB971D0d1b5bcD666a). BLK is a standard ERC20 token with a fixed supply of 1,000,000,000. There is no mint function, so nobody can ever make more.
The presale contract (0x230AcddEFED9202db139C03157056631edc250D5). It takes your USDT and sends you BLK in the same transaction, at the price of the current phase: $0.10, $0.12, $0.14 or $0.15. Every purchase is on the public record.
Both contracts are verified on Polygonscan, so anyone can read the code. They have not been audited by any independent firm.
Both are owned by one Ledger hardware wallet, held by me. It is not a multisig. The owner key cannot mint and cannot take back BLK you have bought. It can pause all BLK transfers, withdraw the USDT raised, pause or end the presale, change the phase, change the minimum and maximum purchase, switch on a whitelist so only listed wallets can buy, and take back unsold presale BLK. The trust page lists all of it.
What Does Not Run on Polygon
The property. Nothing in either contract is connected to any building, any rent or any property value. The contracts sell a token and record who holds it. That is all they do.
BLK gives no ownership of property and pays no rent, no dividends and no returns. Any profit from property stays in BlockHaus to buy more property and run the business. If you want to know how that differs from tokenised property platforms, read what tokenised real estate actually means.
Polygon Compared With Other Networks
| Network | Typical fee | Works with MetaMask | Used by |
|---|---|---|---|
| Ethereum | Dollars, more when busy | Yes | Many large projects |
| Polygon | A few cents | Yes | BlockHaus, Binaryx |
| Gnosis Chain | A fraction of a cent | Yes | RealT |
| Algorand | A fraction of a cent | No, needs its own wallet | Lofty |

What This Means If You Buy BLK
You need a wallet that supports Polygon, at least $20 of USDT on Polygon, and a few cents of POL in the same wallet for the fee. The step by step guide is in how to buy BLK. BLK is only sold at theblockhaus.io/presale.
BLK is not listed on any exchange and no listing date is fixed, so for now it cannot be sold. It has no guaranteed value, and you can lose everything you pay. The presale is not open to residents of the United States, the United Kingdom, the United Arab Emirates, or countries under UK sanctions.
