In this guide, you will learn how to configure the extension on Google Chrome to send and receive tokens, and interact with the Cronos zkEVM network.
Cronos zkEVM is supported by default, no configuration is needed.
You need to:
Download the browser extension for desktop.
And then either create a new wallet (in this case, the seed phrase will be generated by the wallet), or import an existing wallet (using the seed phrase or private key).
Rabby Wallet has integrated Cronos zkEVM Mainnet. Once the wallet is connected, you will be able to view the balance of your address on mainnet, for example:
For connecting your Rabby wallet to the Cronos zkEVM Sepolia testnet:
Open the Rabby extension and click on the "More" icon:
Select "Add custom network":
After clicking "Add custom network" once more you should see a window similar to this:
Here you can enter the details of Cronos zkEVM testnet:
Name: Cronos zkEVM Sepolia Testnet
New RPC URL: https://testnet.zkevm.cronos.org/
Chain ID: 240
Symbol: zkTCRO
Subsequently, to connect to the network, you will need to click on the "Network" icon in the Rabby main window:
Here, you can select Cronos zkEVM Sepolia testnet under Custom networks:
To see your zktCRO test tokenbalance, click on the arrow next to network, then "Custom network" and you should see your zkCRO balance:
If you need to execute cross-chain transactions between Cronos zkEVM testnet and Ethereum testnet, you definitely need to configure the Ethereum Sepolia testnet too.
The procedure is similar to above.
For example:
Name: Ethereum Sepolia
Chain ID: 11155111
Symbol: SepoliaETH
After saving the network configuration, we should be able to see your SepoliaETH token balance.
