To display a favicon for your decentralized app (dApp) in Trust Wallet, you need to set the favicon in the metadata of your dApp's website. Trust Wallet, like most web browsers and mobile wallets, uses the favicon specified in the website's HTML metadata to display the icon.

Here's how you can add a favicon to your dApp:

  1. Create Favicon Image: Create a square image that will serve as your favicon. The recommended size for favicons is 32x32 pixels or 64x64 pixels. Save this image as favicon.ico or favicon.png.

  2. Add Favicon to Your dApp's Website: In the <head> section of your dApp's HTML file, include the following line to reference your favicon:

html
<link rel="icon" type="image/png" href="/path/to/favicon.png" sizes="32x32">

Make sure to replace /path/to/favicon.png with the actual path to your favicon image.

For example, if your favicon is placed in the root directory of your website, the link tag would look like this:

html
<link rel="icon" type="image/png" href="/favicon.png" sizes="32x32">
  1. Upload Your dApp's Website: Make sure your updated HTML file with the favicon reference is uploaded to your dApp's website hosting server.

  2. Test in Trust Wallet: After you have made these changes, open your dApp in Trust Wallet. The favicon should now be displayed in the address bar and on the tabs within the Trust Wallet browser.

Remember that Trust Wallet, like other browsers, may cache the favicon, so it might take a little time before you see the updated favicon after making the changes.

Additionally, since dApps are usually built on top of specific blockchains like Ethereum, Binance Smart Chain, etc., make sure your dApp's URL is accessible and that your dApp's metadata (including the favicon) is correctly set up in any decentralized app stores or directories where it is listed.

Keep in mind that Trust Wallet is an external application, and users may have different versions or settings that could affect favicon display. As a developer, you can ensure your dApp's metadata is correctly set up, but you cannot control how individual users' wallets or browsers handle favicon display.
