Typhon has inbuilt support for mainnet & public testnet Cardano networks. Users can change network inside the wallet, and this change is sent to the dApp via an event. Typhon will by default submit the transaction requested by dApps to the network, but this behavior can be changed as detailed in this document in the later sections. If dApp chooses not to submit the transaction, Typhon will return the signed transaction cbor, which can be used to add additional signatures and submit it from the dApp's backend.
More details on the specifics of the available transaction methods are available in the Methods section
