Wallet: MetaMask | Extension



MetaMask provides wallet functionality for Ethereum and ERC20 assets and allows users to interact with Ethereum DApps through the browser. It’s a useful tool for POA network interaction and integrates well with MyEtherWallet and MyCrypto.

In addition, it blocks malicious sites and keeps wallet keys secure within the application.

POA Tokens

To check a balance, be sure the correct network is selected in the Network dropdown ( core.poa.network or sokol.poa.network )

Currently, POA token balances in your MetaMask wallet are named ETH rather than POA. This means the conversion rate is not accurate. The value next to ETH is the number of POA tokens you hold on the network you have selected.

POA20 Tokens

POA20 tokens (see the POA bridge DApp for more info) can be stored in MetaMask using the same wallet address you use for POA tokens. However, POA20 tokens live on the Main Ethereum Network rather than a POA network.

To view, you must create the token type in the MetaMask application.

  • Token Symbol: POA20
  • Decimals of Precision: 18

  1. Verify the balance of POA20 Tokens in your account.

Please see the Bridge FAQs for more information on POA20 tokens.

Currently, MetaMask does NOT have a UI for sending or receiving ERC20 tokens like POA20. To send and receive, use in tandem with a browser wallet such as MyEtherWallet / MyCrypto or use a mobile wallet like Trust Wallet.


MetaMask works with a variety of applications and plays well with MyEtherWallet and MyCrypto. See our MyEtherWallet and MyCrypto pages <will link to page> for more information.
