it's gotta be the ecdsa public key tho, 33 bytes and all that. i didn't know that x509s can be secp256k1 tho. i thought r1 was the only one that most of the things permitted. TLS definitely. also JWT only r1.
x-only pubkeys are prefixed with 02
it doesn’t matter though, you can flip it

Not sure if x-only have a 02 prefix like same way compressed public keys do?
No, you can prefix them with 02 to get a compressed pubkey.
Ah right, yup!
