useSendBalance

In case you need to programmatically open the send balance widget, you can use our useSendBalance hook to request the UI and optionally prepopulate the form for the user.

How it works

The useSendBalance hook depends on the DynamicContextProvider, so it has to be used as a child of the Dynamic context. When you use the hook, you will get a function named open. That method accepts the follow options:

Parameter	Type	Description
recipientAddress	String	The initial recipient address
value	ethers.BigNumber	The initial transaction amount

The open function will return a promise; If successful, the promise will be resolved with the transaction; if not successful, the promise will be rejected accompanied by the error collected from the provider. Here is an example of a custom Send button

import { useSendBalance } from "@dynamic-labs/sdk-react-core";

const MySendButton = () => {
  const { open } = useSendBalance();

  return <button onClick={() => open()}>Send</button>;
};

From this example, when the user clicks the button, they will be prompted to fill the amount and recipient fields, review the transaction, and they will see a confirmation at the end of the flow. For the second example, we will pre-populate the recipient and amount fields for the user.

import { useSendBalance } from "@dynamic-labs/sdk-react-core";
import { parseEther } from "ethers";

const MySendButton = () => {
  const { open } = useSendBalance();

  const onClickSend = async () => {
    try {
      const tx = await open({
        recipientAddress: "<address>",
        value: parseEther("1"),
      });
    } catch (err) {
      // Handle the promise rejection
    }
  };

  return <button onClick={onClickSend}>Send</button>;
};

Here, when the user clicks the button, they will be prompted with the same UI, but now it will be pre-populated with the recipient address and amount.
