Document signing application


Yahli is an application for signing documents in a confidential and secure way. Yahli protects your data by storing the encrypted file on ipfs. And only the counterparties are able to read the file by decrypting it. Yahli uses Ethereum as a registry where you will be able to find file cid related to your account. In the future, we will implement an optimistic rollup on it for improving the scalability.

How it's made

Tools like metamask or Truffle suite are help us to integrate all these technics. We use a set of technology like Gas station network, asymmetric encryption, and optimistic rollup. What is impressing me the most it's the way we are able to mix multiple blockchain technologies in order to create Yahli.
