Come and join us on our first endeavor down the web3 and NFT rabbit hole. We aim for the stars, land on the Moon first. Realistic. Step by step. Two Earthling brothers with software engineering and healthcare background are tinkering with blockchain to unchain the balloons. They won’t pop, will not disappear, thanks to [Arweave](https://www.arweave.org/), the permaweb. You get the **security of the Ethereum network** combined with **permanent storage**. Not your average centralized solution. Are you ready to take off?

### “Wen” public minting?

*   public mint is open @ 0.003141 Ξ

*   private minting was open for [AffeMitWaffe](https://twitter.com/monkeyverseDAO) holders in 2022.
    
*   we deployed our contract on Ethereum mainnet on 12th Apr 2022,
    

    contract address:  0xB5dFA399Dc4a3BfEB196395746f82fA089D788E1
    

*   the smart contract was audited by [Solidity Finance](https://solidity.finance/), full security pass:

### What’s up with the numbers 3141 (max token supply) and 0.003141 Ξ (price) ?

*   we did not want to overinflate our small project’s market cap (neither our balloons)… 3141 vs the usual 10k max supply.
    
*   we wanted to offer you a favourable risk/benefit price ratio, hence the low entry price 0.003141 Ξ (ETH).
    
*   last but not least: 3.141… represents the number (pi)π which is used to calculate the area of a circle A = _π x_ r^2 (i.e. our balloons) and its decimal value is infinitely long, therefore it also encapsulates limitless opportunities (a symbol of hope).
    

**No promises, no roadmap** (well, there is no road after all, expanding to untouched territory), however as you ascend with your freshly minted/purchased hot air balloon in the metaverse, you soon notice an emerging, fascinating landscape:

*   more NFT projects are on the horizon on ZK-Rollups ([zkSync](https://zksync.io/) and [StarkWare](https://starkware.co/))
    
*   possibility of charity in the healthcare sector – complete transparency on the blockchain
    
*   a photography art NFT project
    
*   possible introduction of NFT utilities (claiming real world assets, whitelist spots,etc)
