Transactions are a fundamental piece of Quai Network. Every state-changing operation within the network requires a signed transaction.The Quais SDK provides utilities for building and signing transactions, with support for all 3 types of transactions.
In practice, developers will only ever need to compose Quai or Qi transactions. External transactions are created and routed automatically by the network, given the sender and reciever addresses of a given transaction.
The QiTransactionRequest type is used to build Qi UTXO transactions. These transactions can be signed and broadcasted to the network using a QiHDWallet.Qi transactions are signed using MuSig signatures.
Qi transactions are still being developed. They are currently supported by the SDK, but are subject to change.
