The Nifty Wallet fork of MetaMask supports both ETH and the POA network, which means that today you can take advantage of fast and cheap transactions and keep your ETH address.
I like the Nifty Wallet more.
How do I install MetaMask? (Nifty Wallet is installed in a similar way from the Google app store)
What does gaming expansion look like?
Let's take the example of the DopeRaider game. (screenshot on the right). For example, we need to buy some marijuana seeds for sale. This action costs 0,0005eth in the game economy + Ethereum network commission. After clicking on the buy button, we get an extension window (in my case Nifty Wallet) with parameters for sending a transaction.
For example with such parameters. The gas limit is 1408372 (how much gas is needed for shipment) at the price of 20Gwei gas. The 1st is multiplied by the 2nd and divided by the billion. We get the cost of the commission = 0,028167ETH. The transaction fee is calculated in the same way in the POA network. We got 0,0005eth seed price + 0,028167ETH commission. If we are satisfied with the transaction value. We press ACCEPT and the transaction is sent to the game's smart contract, all this is recorded in the blockchain and after that the result appears in the game. The commission is expensive. If this happened in the POA network, then the transaction price is several thousand times cheaper. It turns out that this extension is needed for the interaction of what is happening in your browser with your wallet and the game's smart contract.
