# MTRG Crosschain Info

## The Meter Passport

[Meter Passport](https://passport.meter.io) allows MTRG and other ERC20 and ERC721 tokens to be transferred among the supported blockchains. 

Here is important information about MTRG on different chains.  To reduce user confusion, we have decided to call all wrapped versions of MTRG on different chains as MTRG.  The Ethereum version was deployed earlier and was called eMTRG.

## Operating the Same Account on Metamask and Meter Wallet

Metamask configuration information can be found in the previous section

Meter Wallet supports native Meter transactions including staking, starting candidate nodes, vote on candidates.  Metamask is used in the Ethereum emulation mode to interact with dApps.  It is easy to operate the same account in both Meter Wallet and Metamask.  Meter wallet is completely [open sourced](https://github.com/meterio/meter-wallet).  Your private key will only be encrypted and stored on your local computer.
