Transfer tokens privately to one or more Unlink addresses. The sender is the account bound to your user client. See Quickstart. Sender, recipient, and amount are all hidden by a zero-knowledge proof; see How Unlink works. The transfer() method signs with the spending key from the account bound to createUnlinkClient. All public account constructors support private transfers.

​
Single recipient

const tx = await client.transfer({
  recipientAddress: "unlink1...",
  token: "0xTokenAddress",
  amount: "500000000000000000",
});

const confirmed = await tx.wait();
console.log(confirmed.confirmationStatus); // "confirmed" | "processed" | "failed"
confirmed means the transaction has been observed; it does not always mean new private funds are spendable. If your next action spends funds from a recent deposit or transfer, check confirmed.fundsUsable or wait with tx.wait({ until: "processed" }).

​
Multiple recipients

const tx = await client.transfer({
  token: "0xTokenAddress",
  transfers: [
    { recipientAddress: "unlink1aaa...", amount: "100000000000000000" },
    { recipientAddress: "unlink1bbb...", amount: "200000000000000000" },
  ],
});

await tx.wait(); // resolves at user-facing confirmation by default
