Configure Wallet

To send a Quai transaction, you’ll first need to connect a Wallet or QuaiHDWallet to a Provider.

const provider = new quais.JsonRpcProvider('https://rpc.quai.network', undefined, { usePathing: true })

// initialize wallet
const wallet = new quais.Wallet(privateKey, provider)

// initialize HD wallet
const hdWallet = quais.QuaiHDWallet.fromMnemonic(mnemonic)
await hdWallet.connect(provider)

Build Transaction

Then, build the transaction you want to send using the QuaiTransactionRequest type.

// get to address from wallet
const from = wallet.getAddress()

// get to address from HD wallet
const addressInfo = hdWallet.getAddressNextAddress(0, quais.Zone.Cyprus1)
const from = addressInfo.address

// build simple transfer transaction
const txData: QuaiTransactionRequest{
  from,
  to: "0x002F4783248e2D6FF1aa6482A8C0D7a76de3C329",
  value: quais.parseQuai("1.0"),
}

The above transaction is a simple value transfer. Additional transaction params for more complex transactions can be found in the QuaiTransaction class.

Send and Sign Transaction

Finally, sign and broadcast the transaction using your wallet of choice.

// send transaction with wallet
const tx = await wallet.sendTransaction(txData)
const txReceipt = await tx.wait()

// send transaction with HD wallet
const tx = await hdWallet.sendTransaction(txData)
const txReceipt = await tx.wait()
