EasyLink: Receive payments without exposing your crypto history
EasyLink is a private payments protocol that allows you to receive payments without sharing your crypto wallet address. When someone would like to pay you, you can generate a payment link that provides no knowledge about your wallet address, so your on-chain history stays private and the sender will never know what is your welfare or what funny NFTs you hold
Application type
zkDAO
Proposal Overview
Within the scope of this proposal dApp implementation that:
allows users to generate a payment link that has no information about the user’s wallet address
allows payers to pay using provided payment link
using zero-knowledge proof allows the creator of the link to withdraw money in a private and secure way
Use Cases
allows receiving payments without exposing wallet address and on-chain history
can be used as a mixer, when you pay your own payment link
Competitive Landscape
There are protocols that also try to solve payment privacy problems.
For example, AZTEC is focusing on hiding the transaction amounts, Tornado.Cash is focusing on hiding the origin of the money, and Tornado Nova has shielded transactions, but to initiate it recipient needs to be registered in the pool and share his/her wallet address.
Proposal Ask
EasyLink protocol will become community-driven and self-funded by transaction fees and its own DAO. In order to get this up and running, we will be requesting the $15k/year stable basic income to take care of initial development, welfare, and operations costs.
Taking into consideration the recently announced Technical Innovation Awards I’m proposing the following milestones for this ask:
launching a feature-complete product on our testnet
I would say yes for the general category, but I think the circuits in your project do not qualify for the Technical Innovation Awards since they are pretty much based on Tornado Nova. Maybe you can elaborate a little bit more on why you think your project is an innovation?
I would mostly agree with you that current circuits are mix from the best parts of both versions of Tornado protocol.
I have decided to apply to Technical Innovation Awards category as right now I’m designing a circuits that would allow to deposit and withdraw multiple tokens with arbitrary amounts and check that amount and currency wasn’t amended by the sender, but as I see here there is possibility to be nominated later, so I think it would be fair to apply to general category right now and ask to re-evaluate it it once new circuits are implemented.
Thank you for you comment
I think that’s probably the way to go. In that case, would you mind amending your proposal so that our governors can vote for it as an application to the general category for now? Thanks.
You can simply put the amended milestones as a reply here.

I’m proposing the following milestones for this ask:
launching a feature-complete product on our testnet
forming a DAO with 5-out-of-9 multisig with our DAOs
launching on our mainnet with audit
attracting 1k daily active users (with launch video, full PR promotion)
attracting 10k daily active users (with a detailed roadmap, governance process)
This is a yes from me as well and milestone 1 is confirmed. Looking forward to seeing your custom circuit that will allow the deposit and withdrawal of arbitrary amounts
Nice application of zkp for privacy. Approved as governor of zkdao (milestone 1 confirmed).
