Interacting with Meter Mainnet Using MetaMask

Meter mainnet now supports two transactions (tx) formats:
  1. 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 from the Meter website or Github.
  2. 2.
    Ethereum tx: This is designed for backward compatibility with existing Ethereum dApps and ecosystem including wallets like Metamask.
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.
