Let's add a decentralized dev.to proof to your OpenPGP keys.
Log in to dev.to and create a new post with the following text (make sure to replace FINGERPRINT and USERNAME):
This is an OpenPGP proof that connects [my OpenPGP key](https://keyoxide.org/FINGERPRINT) to [this dev.to account](https://dev.to/USERNAME).
For details check out https://keyoxide.org/guides/openpgp-proofs
[Verifying my OpenPGP key: openpgp4fpr:FINGERPRINT]
After posting, copy the link to the post.
First, edit the key (make sure to replace FINGERPRINT):
gpg --edit-key FINGERPRINT
Add a new notation:

Enter the notation (make sure to update with the link to the post copied above):

Upload the key to WKD or keys.openpgp.org (make sure to replace FINGERPRINT):
