You are required by most Dexes on Solana to revoke at least Metadata Authority before you are granted permission to list your token on their Dex. You can do this for free when creating your token on Solauncher.
To revoke your token authorities, first select your SPL/token address and proceed to select what you want to revoke.
Next is to click on the Revoke button, wait for the wallet pop up and sign transaction to complete process.
