I thought it could be an interesting topic to discuss here, as designers we probably lack the tech knowledge necessary to make this happen.

The issue is also a BIP on the bitcoin repository https://github.com/bitcoin/bips/pull/1551

And here the issue opened on the Bitcoin design repository https://github.com/BitcoinDesign/Meta/issues/638

In reality, we already have it on the Lightning network, it would make sense to apply it to onchain addresses too? It would even possible to do?
