Summary

Dynamic Send Balance Widget allows users to send their funds to another wallet when using an embedded wallet. Users using embedded wallets will automatically have a send button in the dynamic widget, or you can trigger the same UI from your website using our useSendBalance hook.

DynamicWidget usage

If your website is using the Dynamic Widget, the send button will be automatically available for users using embedded wallets. When a user opens the Dynamic Widget and selects an email based wallet, for example, the Send button will appear for them.

useSendBalance hook

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:

ParameterTypeDescription
recipientAddressStringThe initial recipient address
valueethers.BigNumberThe 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 { ethers } from "ethers";

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

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

  return <button onClick={onCickSend}>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.
