It is not that the DApp page actively reads accounts on its own. Instead, the wallet returns all account addresses you checked and authorized, but the page will only recognize the currently selected primary account in the wallet by default. This is the fixed logic of wallet and DApp interaction. Currently, tools like MetaMask and WalletConnect support checking multiple accounts for authorization at the same time. The DApp will treat the first item in the received address list as the current operating account.

Which Account Is the Page Actually Reading?
To confirm which address the page is currently using: check the wallet address starting with 0x displayed in the top right corner or menu of the DApp page, then open your wallet and check the address of the currently selected account at the top. If the two match, it means the page is reading the correct account.
Verification standard: the addresses match, and the balance shown on the page is consistent with the actual balance of that account in the wallet.
What Happens If You Select Multiple Accounts When Connecting?
If you check two accounts, the DApp will receive an address list like [Account_A, Account_B], and by default it will treat Account_A, which is listed first, as the default connected account. In the wallet connection library Wagmi, there was a long-standing compatibility issue: the first item in the list returned by eth_requestAccounts is the wallet's currently selected account, but the list returned by wallet_requestPermissions is arranged in the order the user checked. When these two logics conflict, it can cause the DApp to call the wrong account.

Common Failure Reason: You Switched Accounts but the DApp Is Still Using the Old One
After you switch to another account in the wallet, the DApp page still shows the old account's address and balance. This is not because the page read the wrong account, but because the account change notification was not re-triggered in the DApp after switching accounts.
The WalletConnect specification requires the wallet to actively notify the DApp through the accountsChanged event when the user switches accounts. However, in some older wallet versions or special connection scenarios, this event is not triggered, and the DApp will remain in the old session state.
Solution steps:
- Find the "Disconnect" button on the DApp page and terminate the current authorization session
- Go back to the wallet and initiate the connection process again. In the authorization popup, check only the single account you need to use
- After the connection is complete, check whether the address displayed on the DApp page has updated to the target account
High-risk warning: there is a hidden security pitfall. If you switch to an account in the wallet that is not authorized for the current DApp and then initiate a transaction, MetaMask will by default use the wallet's currently selected account to sign. But the DApp's recorded authorization list does not contain that address. The transaction will still be sent normally and gas will be deducted, making it very easy to use the wrong account. Therefore, do not casually switch accounts in the wallet. After switching, be sure to go back to the DApp page, disconnect, and reconnect.
Verification method: switch the wallet's current account to the target account you intend to use, disconnect the DApp and reconnect, then confirm that the address in the top right corner of the DApp page is updated synchronously. This means the page has correctly read the account you selected.
