# Configure Custom Mainnet Tokens

The Libre blockchain supports [BTC and USDT as wrapped tokens](https://libre-chain.gitbook.io/libre-docs/cross-chain-interoperability/pnetwork) issued by the [PNetwork](https://docs.p.network/).  Anchor needs to be configured to track balances of these tokens on the Libre blockchain.

From the "Home" screen for the Libre blockchain, select "Tokens".
