# ETH Cross-chain
The Nerve network is currently in the Beta version, so it is also connected to the ETH test network, so users should pay attention to use the Ethereum test network to make cross-chain transfers to the Nerve test network
# Prepare ETH test coin
Visit Chrome's App Store (opens new window), find the Meta mask, and create an Ethereum account
Select Ropsten test network, and then click the [Transfer] button
Click[Get Ether]to receive test ETH
# Transfer ETH to Nerve network
Enter Nerve's Testnet Light Wallet (opens new window), on the transfer page, find ETH, click [cross-chain transfer], you can see the entrance, cross-chain transfer to ETH Will be divided into two steps
Step 1: Transfer ETH to the bound Ethereum account
Each Nerve address has a paired Ethereum account, the private key of the account is the private key of the Nerve account, so the assets of the Ethereum account are still controlled by the user himself
Step 2: Confirm cross-chain transfer
After entering the amount of ETH to be transferred in the input box, initiate a transaction, and the ETH in the bound Ethereum account will be transferred from the Ethereum network to the Nerve network through the cross-chain, and the address of the receiving asset is the current Nerve address.
Tips: If the cross-chain transfer is ERC20 assets, you need to pay attention to whether there is enough ETH to pay transaction fees in the bound Ethereum account (cross-chain transfer also needs to be packaged and traded on the Ethereum network, so it needs to consume ETH)
