### Fill in the network info

You'll be presented with a page asking you to fill in the network info, which will be found in the following table:

<table><thead><tr><th align="center">Network Name</th><th align="center">Chain ID</th><th align="center">Currency symbol</th><th width="200" align="center">Block Explorer URL</th></tr></thead><tbody><tr><td align="center">Ethereum Mainnet</td><td align="center">1</td><td align="center">ETH</td><td align="center"><a href="https://etherscan.io/">https://etherscan.io/</a></td></tr><tr><td align="center">Polygon Mainnet</td><td align="center">137</td><td align="center">MATIC</td><td align="center"><a href="https://polygonscan.com/">https://polygonscan.com/</a></td></tr><tr><td align="center">Arbitrum  Mainnet</td><td align="center">42161</td><td align="center">AETH</td><td align="center"><a href="https://arbiscan.io/">https://arbiscan.io/</a></td></tr></tbody></table>

Tips：don't forget to give the network a different name to distinguish it from the original one:
