​
Using Blurhash

The blurhash field provides a compact string that encodes a blurred placeholder of the logo. Blurhash improves perceived performance by displaying an instant preview while the actual logo loads—no layout shifts, no blank spaces, just smooth transitions. The entire placeholder is encoded in ~20-30 characters. For implementation details and code examples, see the official blurhash documentation with decoders available for TypeScript, Swift, Kotlin, and more.

Keep your secret a secret, keep it safe

Unlike the publishable key, it’s your responsibility to keep your secret key safe and away from public eyes. Even during testing, please never publish to Github or allow it to be seen from front-end code. If you’re secret key is ever leaked, please get in touch immediately so we can regenerate a new one for you.
