It's not possible to change the wallet directly on Fnatic ID profile. If you didn't add your own wallet, you can export your private key, this will give you the ability to transfer it elsewhere. Although we wouldn't recommend this right now as we've not built the mechanics to track transfers yet. We're currently working on a flow around this which will allow users that purchase from secondary sources can still connect with Fnatic ID, so we can honor key holders whether it comes from the initial claim on our platform or a secondary source.
