Here, we can see that two validators are randomly producing blocks, fully compatible with NPOS (Nominated Proof-of-Stake).

Connect MetaMask Wallet

The following steps assume that you have already created a wallet address. If you haven't created a wallet yet, please create one in MetaMask first.

1. Add your network to MetaMask.

   Network name: Frontier Testnet
   Default RPC URL: http://localhost:9944
   Chain ID: 42
   Currency symbol: UNIT
   

   

2. Connect to your network and copy your wallet address.

   1. select network
   
   2. copy your address
   

3. Use CHARLETH to transfer UNIT to your wallet address in the explorer. Your MetaMask wallet will display the balance.

   1. transfer
      
   2. balance
      

Run your scan (Blockscout)

Transactions in the EVM can be viewed on this scan.

1. deploy

   git clone https://github.com/ChainSupport/blockscout.git
   cd blockscout/docker-compose
   

   docker-compose up --build
   

2. When you send token to any address from MetaMask, you will find the transfer record on the scan.

   1. Send token by MetaMask
      
   2. transactions
      

Note: Currently, Blockscout does not support displaying native transfer records, meaning transactions made through the Balances pallet are not shown here. (We plan to provide support for this in the future.)

Deploy a smart contract
