Where do I locate my wallet address
Your account name is your “address”, if you’re looking to withdraw from an exchange.
Many blockchains still use long public keys as addresses and exchanges just typically label those fields as an “address”. EOSIO blockchains all use account names though.
One thing I do to get a feel for new exchanges/blockchains is just do a small withdraw to make sure it works. I’d recommend giving that a try, using your account name, and make sure it works!
