Bridge test tokens to Cronos zkEVM testnet

How to deposit tokens from L1 to L2 (testnet)

In order to complete this step, you need the following:

Your crypto wallet must be set-up and connected to Ethereum Sepolia testnet

You must have some SepoliaETH as well as some test ERC20 tokens (zkTCRO or other) in your wallet, on the Ethereum Sepolia testnet network.

See this page on how to acquire test tokens: Get test tokens on Layer 1

Visit the temporary testnet bridge at:

Your wallet may request 3 to 4 signatures consecutively to complete the transaction. Be patient.

Sometimes, transactions fail if Sepolia is too busy. As Sepolia is a testnet, its gas price varies suddently, which can cause transactions to fail. There is not much that we can do. You may need to try multiple times.

The Cronos zkEVM testnet bridge displays the following tokens by default:
