A Custom built crypto wallet is made from scratch for your business. You can choose all features, design, and security. It gives full control, but it takes more time and costs more money.
A White label crypto wallet is already built. You just change the name, logo, and colors and launch it quickly. It is cheaper and faster, but you cannot change much inside it.
So, white label is good if you want to start fast and spend less. Custom built is better if you want full control and a unique product for the long term. If you want to know more, refer to the Crypto Wallet Development (https://www.hashcodex.com/cryptocurrency-wallet-app-development) page.
