These are the only two contract addresses BlockHaus uses. Both are on the Polygon network.
- BLK token:
0x5cF704a1F5B5555B7369F4AB971D0d1b5bcD666a - Presale:
0x230AcddEFED9202db139C03157056631edc250D5
If someone sends you a different address for BLK, in a Telegram group, a DM or a comment, it is not ours. The same two addresses are always on our trust page, so check them there before you do anything.
How to check the addresses yourself
It takes two minutes.
- Open Polygonscan and paste the token address into the search bar.
- The token name should read BlockHaus and the symbol BLK.
- Open the Contract tab. A green tick means the code is verified, so the source you are reading is exactly what runs on the blockchain.
- Do the same with the presale address. Its token transfers tab shows every USDT payment in and every withdrawal out.
Copy and paste addresses. Never type them by hand, and never trust one from a screenshot.
Adding BLK to your wallet
BLK only shows in your wallet once your wallet knows about it. In MetaMask or Trust Wallet, make sure you are on the Polygon network, choose Import token, and paste the token address above. The symbol and decimals fill in by themselves.
What the owner key can and cannot do
Both contracts have one owner, a Ledger hardware wallet held by me. It is not a multisig. Here is what that key can do, read straight from the code:
- It cannot create more BLK. The supply is fixed at 1,000,000,000 and there is no mint function.
- It cannot take back BLK you have bought. Your BLK arrives in your wallet in the same transaction you pay in.
- It can pause all BLK transfers, including yours. That is an emergency switch, for example if a wallet is hacked, and it is the biggest power the owner has.
- It can withdraw the USDT raised from the presale contract. Every withdrawal is public on Polygonscan.
- It can pause or end the presale, move it to the next price phase, change the minimum and maximum purchase, switch on a whitelist so only listed wallets can buy, and take back BLK the presale has not sold.
I would rather you know all of this before you buy than find it out later. The trust page reads the live numbers from the blockchain every time you open it.
Has the contract been audited?
No. The code is public and verified, so anyone can read it, but no independent security firm has audited it. If a firm does, the report will be linked on the trust page.
Staying safe
- Only buy through theblockhaus.io/presale. There is no other sale.
- Nobody from BlockHaus will ever ask for your seed phrase or private keys, or ask you to send money to a person or a wallet.
- BLK cannot be traded until it is listed on an exchange, and no listing date is fixed yet. Anyone offering to sell you BLK somewhere else is not us.
BLK is a utility token. It has no guaranteed value, pays no rent or dividends, and gives you no ownership of any property. Read the trust page before you buy, and only buy what you can afford to lose.
