Inspiration

Currently as a payer, in order to send a recipient money on EVM-compatible blockchains, he or she needs to know the address of the recipient. However, a recipient may feel uncomfortable sharing his or her wallet address with the payer because:

it allows the payer to make a connection between the recipient’s wallet and the identity of that recipient
it exposes all of the recipient's financial history to the payer (ex. number of tokens, amount of each token, transaction histories of each token, NFTs, and to whom and where money is being sent or received)

What it does

Wisp is the first decentralized bank protocol which allows anyone to:

Receive payments without revealing their wallet addresses
Send payments straight from their Wisp wallet
Download account statements for official reporting
Passively re-invest money right from their wallet (under development)

How we built it

DApp frontend is built using Next.js and TypeScript
DApp utilizes SNARK zero-knowledge proofs and asymmetric cryptography to keep your assets secure and private
ZK circuits are built using circom language and solidity verifies are exported via snarkjs
Smart contract wallet allows automatic funds reinvestment

What's next for Wisp

Re-invest funds in the smart contract using Aave or own lending protocol for APY gains
Turn the app into a full-featured wallet
Allow private NFT transfers
Wisp SDK for private payment integrations
