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
zksync-zkwallet-vue
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:

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:

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.
