Astar zkEVM Quickstart Guide

Astar zkEVM is a zero-knowledge scaling solution for Ethereum that offers an EVM-equivalent environment on which existing EVM smart contracts, developer tools, and wallets can work seamlessly. Astar zkEVM harnesses the power of zero-knowledge proofs to reduce transaction costs and increase throughput, while inheriting the security of Ethereum.

Solidity developers are right at home on Astar zkEVM. Simply switch to the zkEVM RPC, and start building!

Reminder

No special tools or wallets are required to build or interact with Astar zkEVM.

Developers can deploy existing contracts from other EVM chains to the zkEVM, and users are able to deposit assets from Ethereum to transact on the zkEVM in batches, which are ultimately finalized through novel use of zero-knowledge proofs. Native account abstraction means developers can craft user interfaces that are more intuitive and web2-like, that eliminate complexity and drastically simplify the onboarding process.

Connecting to zkEVM​

To add Astar zkEVM or any testnet networks to your wallet manually, enter the following details :

RPC URLChainIDBlock Explorer URLCurrency
https://rpc.startale.com/astar-zkevm3776https://astar-zkevm.explorer.startale.com/ETH

To add the network to MetaMask you can either use the data above, or find a link to add the network at the bottom of the respective block explorer page.

Bridging Assets​

important

Astar's canonical zkEVM Bridge will be deprecated. We recommend not to transfer any funds to Astar zkEVM because of being transitioned to Soneium layer 2 in 2025, more info here.
