Now I am experimenting to mint a token on cardano testnet I have installed the followings like deadalus wallet for testnet and cli tools as well.Then I recived ada from the testnet to the testnet deadalus wallet Then I have followed thease Instructions over here.

cardano-cli address key-gen \
--verification-key-file payment.vkey \
--signing-key-file payment.skey

cardano-cli address build \
--payment-verification-key-file payment.vkey \
--out-file payment.addr \

cat payment.addr

From the last command which i have executed given me an ada address when I am pasting that address on deadalus wallet it is showing me the address is invalid. I couldnt find much about this from official documentation as well. What should i do now? Where am i going wrong?

Anytime you do things on testnet, you need to replace the --mainnet flag in your CLI commands with the --testnet-magic 1097911063 flag. The address you built above is a mainnet address, which is incompatible with testnet.
