ConsenSys zkEVM

An EVM-equivalent zk-rollup for scaling Ethereum dapps

Get unrivaled scalability using the apps, infra and tooling you love

Build, test and launch dApps with the skills you have and tools you know. Connect instantly with MetaMask and Infura, deploy bytecode as is and deploy apps just as you would on Ethereum.

Low gas fees

Build dApps that users can interact with at scale

EVM equivalent

Fully compatible with existing tooling, infrastructure, IDEs and wallets.

Secured by Ethereum

Backed by the security of Ethereum, where all rollup transactions are verified on-chain by a decentralized community of over 500k validators

Next gen scalability

Innovative lattice-based zkSNARK prover generates fast zero-knowledge proofs.

Scale dapps with zero switching costs

Migrate existing dapps with no code changes or smart contract rewrites

Next generation scaling
Our zkEVM delivers industry leading throughput and opens the door to infinite scaling with L3s
Ethereum aligned
100% EVM bytecode compatibility, so you can deploy your exsiting dapp in minutes without changes
Developer-friendly design
Built to minimize onboarding time, our rollup abstracts away ZK complexity, uses ETH for gas and has no reliance on third party transpilers or bespoke middleware
Highly composable
General purpose rollup designed for atomic synchronous interoperability between all deployed dApps
Industry leading efficiency
Award winning prover built with in house libraries delivers ultra-low gas fees

Accelerate time to value with developer friendly integrations

Build, test and launch dapps faster with native integrations with tools like Truffle, Infura and MetaMask

Connect in seconds
Easy user onboarding with default MetaMask integration
Ship faster and scale with confidence
Infura’s easy to use API abstracts protocol complexity enabling devs to ship faster and scale with the confidence of 99.9% uptime
Use the tools you love
Build, test, debug and deploy Solidity smart contracts with popular dev environments like Truffle, HardHat, Foundry and Brownie
Test locally
Fork and debug the zkEVM locally and test faster with built in Ganache compatibility support
Securely bridge and swap tokens
Safely move tokens on and off network with our native, trustless bridge and access to MetaMask’s user-friendly Bridge

Build with confidence

From the genesis block, ConsenSys has helped build and democratize Ethereum.

Open, flexible architecture
Extensible and modular design will enable developers to configure dApps for their unique privacy, data availability and access control needs.
Grounded in research
Built on four years of research on zk-based scalability, elliptic curves for zk proof systems, zk design circuits, rollups and bridging with full formal verification of cryptography and arithmetization for complete security
Built for Ethereum
Created alongside the teams that designed the Beacon Chain and Ethereum’s Engine API, the ConsenSys zk rollup will be managed as an open source public good alongside Hyperledger Besu, Teku and Web3Signer
Commitment to decentralization
Committed to decentralization and open source development of our prover and arithmetization. With full EVM equivalence there is no developer lock in and protocols can easily port apps to other EVM based networks.

"We are excited to support ConsenSys zkEVM and allow users to bridge between Ethereum and their new chain using the familiar Hop interface. The ease of integration, tooling [and] compatibility allowed this integration to work seamlessly with the existing Hop development stack."

Frequently Asked Questions

Deploying a zk-rollup that offers the same experience as Ethereum is technically challenging. The EVM was never designed to be proven in a zk circuit and therefore most zk-rollup teams decided to go a different path, using bespoke languages and virtual machines separate to the EVM. We felt this created friction for developers familiar with Ethereum.

ConsenSys R&D, along with others in the ecosystem, have been working on an approach to wrap EVM computation in zero-knowledge proofs to create a zkEVM implementation. This zkEVM handles native EVM bytecode for proving and verification to allow the execution of Solidity smart contracts and enable developers to get the benefits of a zk-rollup using the developer tools and infrastructure they are familiar with. You can read more about our goals and the specification here
There are different types of zkEVM. Vitalik’s blog post describes zkEVM’s in types and the goal of our Rollup is to be a Type 2 zkEVM. A Type 2 zkEVM is bytecode-compatible which means we’re the most compatible with Ethereum and the EVM making it easy for developers to build and maintain applications on Layer 2.

We do not use transpilers or custom compilers to generate zk proofs for Solidity smart contracts. We take the compiled bytecode of Solidity. We believe this approach reduces the surface area risk for bugs and hacks.
