Thanks for the update.
I would like to get a refund, but I didn’t set the custom token up yet.
Can’t find the preferences anymore, as the website is closed.
Could someone help me out with this? Would really appreciate any help

I would suggest that you Google "how to add a custom token" + "name of your wallet" as the procedure is slightly different for different wallets.
You then simply enter the contract address: 0xc499ea948a1ad5d8eaf12abd2f67975c4dbe21aa
18 decimals
ANGL
The number of decimals and the code may be pre-filled for you when you enter the contract address.
Then you simple return your ANGL tokens to the following address before April 23rd, 2021:
0xC7D3291CaaBf7Bf1e00a63e20AB584D2208797B5
You will then be refunded with your share of ETH (Ethereum) and BAT (Basic Attention Token) from what is left of the Angel Token Fund at some point before June 30th, 2021 but likely much sooner. Your refund will be sent to the same address that you return your ANGL tokens from.
