To transfer an asset, go to Keymaster, click the arrow next to the Download button, and select "Transfer to another account."
Type the CFX account where you want to transfer it and confirm it in your email from your Keymaster account.
I transferred an asset but now I want it back.
Be aware that if you transfer an asset, you can't get it back due to Keymaster's policy. You receive this message before transfer:
"WARNING: Transfer will remove this license from your account and move it to another Cfx.re account. This action is irreversible and can be done only once for each license."
