Nomadic is a decentralized platfoform bringing web3 community together. It makes co-living arrangement process easy, trustless and newcommers friendly.
Nomadic has 2 primary features: creating/finding a short stay and creating/finding a hacker house. We store prove of previous interactions with our platform(communities user belongs to, previous short stays) using on-chain reputation stored in a soulbound NFT. Smart contract is designed to facilitate chipping in for a stay and also a community governance to allow voting decisions within the hacker house. We want to make our platform as secure as possible and for this reason we are using the proof of personhood powered by WorldCoin's identity tech. We used Skale Network to facilitate chipping for a stay, as well as the equal refund of money if something goes wrong with the booking process. The community protocol allows hacker house members to vote on core team ideas.
Our project uses WalletConnect which makes connecting to our app convenient for our users thanks to QR code pop-up. We wanted to make sure that users who are booking an apartment us or join a hacker house with us are real, and so we used WorldCoin' proof of personhood tech to solve this problem. For deployment we decided to use Polygon and Scale. For storing our updatable NFT metadata we used IPFS.
One of the features of Nomadic is allowing users to create short stays and chip in using deadlines for the short stay to be fulfilled, chainlink keeper is used in a crucial way by allowing a check on the deadlines every certain time, this helps to keep the protocol safe and our users funds safe.
bytes32 _config = config; // Gas savings
// Have we run today?
uint256 day = block.timestamp / 86400;
if (lastRunDay >= day) {
return (false);
}
// Load schedule
uint8 checkDays = uint8(_config[0]); // day of week bits
// Weekday
uint8 weekday = uint8((day + 4) % 7);
// Need a runCheck?
if (((checkDays >> weekday) & 1) != 0) {
runCheck = true;
}
We pass a config bytes that contains in which days we want to run checks, and the keeper will read in low level and perform the operations.
const config = '0x1200000000000000000000000000000000000000000000000000000000000000';
//00010010 wednesday and saturday We want to use this protocol for an actual idea that we came up in Kuala Lumpur, Malaysia. Planning to extend the use of chainlink keepers for actual hacker houses and long term stays happening around the country.
