A Brief Guide to zkRollup Projects and Products — January 2021

A Brief Guide to zkRollup Projects and Products — January 2021

Ethereum is slow and expensive, and with growing popularity will only continue to get slower and more expensive. One of the ways in which the Ethereum community is working to fix both these problems is by using the Layer 2 scaling solution known as zkRollups.

Through my work at Numio I have built up a list of other projects and innovators working with zkRollups.

So here is your brief guide to the projects that are building zkRollup infrastructure, who has released products, and who is planning to launch in the near future.

zkRollup Solution: zkSync

Project: zkSync by Matter Labs.

zkSync is a trustless, secure, user-centric protocol for scaling payments and smart contracts on Ethereum

Token: None at present, but have announced they will be launching one.

zkSync Product: zkWallet

Documents: https://zksync.io/faq/intro.html

GitHub: https://github.com/matter-labs/zksync

Ecosystem Products using zkSync:

Live

Numio

Numio make crypto easy by building payment and storage applications that anyone can use.

The Numio app was the world’s first non-custodial, zkRollup powered, Ethereum mobile wallet to be launched in the Google Play Store.

GitCoin

Gitcoin is a community for developers to collaborate and monetize their skills while working on Open Source projects through bounties.

Golem

Golem is a decentralized marketplace for computing power. It enables CPUs and GPUs to connect in a peer-to-peer network, enabling both application owners and individual users (“requestors”) to rent resources from other users’ (“providers”) machines.

Layer 2 payments on zkSync

StablePay

StablePay is a decentralized payment solution that enables users to pay online with their tokens for products and services priced in USD.

In development

Curve

Curve is an exchange liquidity pool on Ethereum (like Uniswap) designed for (1) extremely efficient stablecoin trading (2) low risk, supplemental fee income for liquidity providers, without an opportunity cost.

Layer 2 Meets Curve with zkSync

Balancer

A Balancer Pool is an automated market maker with certain key properties that cause it to function as a self-balancing weighted portfolio and price sensor.

The integration is not yet complete but has been discussed by the Balancer team https://twitter.com/mikeraymcdonald/status/1321095040127668232

Argent

Argent is a simple and secure smart wallet for crypto.

The integration is not yet complete but has been discussed on Discord by the Argent team.

MyKey

MYKEY is a self-sovereign identity system implemented on multiple public blockchains.

The integration is not yet complete — not a lot of information to go on.

zkRollup Solution: LoopRing

Project: LoopRing

Loopring is a zkRollup Exchange and Payment Protocol

Loopring Product: Loopring Exchange & Mobile Wallet

  • Loopring Exchange
  • Loopring Smart Wallet – Apps on Google Play

Token — LRC

Github: https://github.com/Loopring

Ecosystem Products using Loopring:

GitCoin

Gitcoin is a community for developers to collaborate and monetize their skills while working on Open Source projects through bounties.

Rails

Rails allows you to transfer ETH and any ERC20 compatible token from your wallet to anyone else within the Loopring L2.

In Development

pNetwork

The pNetwork is the governance layer of the pTokens system. pTokens are unchained assets, moving liquidity from one blockchain to another.

The integration is not yet complete.

zkRollup Solution: StarkWare

Project: StarkWare

StarkWare improves scalability and privacy in blockchains using STARK technology, providing cryptographic proofs that are zero-knowledge, succinct, transparent (no need for a trusted setup), and post-quantum secure.

Token: None as of yet.

Ecosystem Products built on StarkWare:

zkRollup Solution: ZKSwap

Project: ZKSwap

ZK-Rollups based layer-2 DEX with the AMM model.

ZKSwap Product: ZKSwap Wallet

https://zks.app/en/wallet

Token: ZKS

Ecosystem Products built on ZKSwap:

N/A

zkRollup Solution: Aztec

Project: Aztec

The AZTEC protocol was created to enable privacy on public blockchains by using the zk-SNARKs privacy algorithm to encrypt blockchain data

Aztec

Token: None

Ecosystem Products built on Aztec:

N/A

zkRollup Solution: Hermez

Project: Hermez

Hermez is a trustless ZK-Rollup focused on scaling payments and token transfers on the wings of Ethereum.

Lets build this

Ethereum and zkRollups are going to go from strength to strength through 2021, and as the technology grows so will this list. Let me know if there are any projects or products that I have missed and I’ll add it.

Watch this space.
