Interacting with wallets

In the last section we covered how to access a wallet through the SDK, but said nothing about how to interact with it - let’s fix that! You probably noticed the connector field in the wallet object in the previous section. This is the object that allows you to interact with the wallet. It’s an instance of the WalletConnector interface, which is a generic interface that allows you to interact with the wallet in a standard way.

There are some fields and methods specific to each chain, so what we’ll do here is list the fields available on every single chain, and then you can go to the specific chain page (i.e. EVM interactions) to see the additional fields and methods available for that chain.

​

WalletConnector Interface

There’s a lot going on here, so let’s pick out the main aspects you’ll need to work with. We will give examples for EVM here.

​

Read only actions

If you want to read data from the blockchain, you will want either a “Public Client” (Viem terminology), or a “Provider” (Ethers terminology). Both allow you read only access to the blockchain.

• Viem
• Ethers

import { useDynamicContext } from '@dynamic-labs/sdk-react-core';

const { primaryWallet } = useDynamicContext();

const getBalance = async () => {
  const publicClient = await primaryWallet?.connector?.getPublicClient();

  // Now you can use the public client to read data from the blockchain
  const balance = await publicClient?.getBalance(primaryWallet.address);
  return balance
}

​

Write actions

If you want to write data to the blockchain, you will need a “Wallet Client” (Viem terminology), or a “Signer” (Ethers terminology). Both allow you to sign transactions with the private key.

• Viem
• Ethers

import { useDynamicContext } from '@dynamic-labs/sdk-react-core';

const { primaryWallet } = useDynamicContext();

const sendTransaction = async () => {
  const walletClient = await primaryWallet?.connector?.getWalletClient();

  // Now you can use the wallet client to write data to the blockchain
  const tx = await walletClient?.sendTransaction({
    to: '0x1234567890abcdef',
    value: '1000000000000000000'
  });
  return tx
}
