Transactions

​

Overview

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.

​

Usage

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.

​

Quai Transaction

The QuaiTransactionRequest type is used to build all types of Quai transactions. They can be signed and broadcasted to the network using a Wallet, QuaiHDWallet, or Signer.

Quai transactions are signed using ECDSA signatures.

const tx: QuaiTransactionRequest = {
	to: '0x0012345678901234567890123456789012345678',
	value: parseQuai('1.0'),
	data: '0x',
}

await wallet.sendTransaction(tx)

​

Qi 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.

const tx: QiTransactionRequest = {
  txInputs: [...],
  txOutputs: [...],
}

await QiHDWallet.sendTransaction(tx)
