# Interacting with Meter Mainnet Using MetaMask

Meter mainnet now supports two transactions (tx) formats: 

1. The native Meter tx: which is more expansive and supports staking, on-chain auctions, validator transactions, and future multiple chains/shards. This tx format is used by the Meter mainnet wallet which is a PC/Mac application [downloadable](https://www.meter.io/wallets/) from the Meter website or [Github](https://github.com/meterio/meter-wallet). 
2. Ethereum tx: This is designed for backward compatibility with existing Ethereum dApps and ecosystem including wallets like [Metamask](https://metamask.io/).

Metamask communicates with the Meter mainnet through an RPC (Remote Procedure Call) emulation layer.  The user will have to configure a custom RPC network inside MetaMask. Here is how to do so.
