# Sign transactions from dApp

{% hint style="info" %}
In this instruction, we will sign transactions on Uniswap. This instruction can also be applied to any other Substrate and EVM dApp/website.

The user interface (UI) and buttons you encounter will vary based on the specific designs of each dApp/website.
{% endhint %}

**Step 1:** Open the dApp and connect your account(s) to it from either one of these options: 

* Connect by selecting [the SubWallet option](https://app.gitbook.com/o/CyPU0v2iA12ILmupTKub/s/x2bpnbQM0WCkMm0eOyd6/)
* Connect by selecting [the WalletConnect option](https://app.gitbook.com/o/CyPU0v2iA12ILmupTKub/s/-Lh39Kwxa1xxZM9WX_Bs/~/changes/714/mobile-app-user-guide/connect-dapps-and-manage-website-access/connect-disconnect-dapp-via-walletconnect#connect-dapp-with-walletconnect)

*In this example, we are connecting to Uniswap. Once you've connected your account(s) to Uniswap, it will display as follows:*

**Step 2:** Fill in the necessary information for the transaction.&#x20;

*In this example, we will swap ETH for WETH on the Ethereum Sepolia network. Once filled, hit "**Review**" to begin the process.*
