After the installing, please import the Ethereum wallet first.

Then switch to the Arbitrum network, select [Import]-[Import from other chains], and import the Ethereum wallet

Note: This method can keep the Ethereum wallet and Arbitrum wallet addresses the same, and cross-chain operations need to be performed between the two same addresses.

ERC20 cross-chain (Ethereum -> Arbitrum)

Open https://mathdapp.store and search to find the app Arbitrum Token Bridge for ETH.

Search for the Token to be cross-chain (this article takes MATH as an example)

ERC20 token needs to do an Approve authorization first, and then complete the Transfer signature just like ETH
