Warpy is Venmo + them 🔥 DeFi interests
Warpy smoothly onboards users into a DeFi savings account: sign up with email/phone number & deposit with debit card (Fortmatic), and get interest-bearing DAI (Chai), all without using Ether/gas.
At the same time, Warpy onboards the user and their Chai onto Loom Network, allowing them to send money instantly & for free.
Though Warpy uses Loom Network, it can work with any side chain or roll-up chain that has an asset bridge with Ethereum Mainnet.
contracts/WarpyRelayer.sol is the main smart contract.
function depositDAI(address to, uint256 amount, uint256 expiry, uint8 v, bytes32 r, bytes32 s) public
Transfers DAI from the user using a signature, converts it into Chai, and deposits the Chai into the Loom Network Transfer Gateway contract, which will make the Chai available on the Loom Network.
Also takes a fixed fee (2 DAI), which is converted into ETH via Kyber Network, to cover the gas cost on the Gas Station Network.
