What are cowboy credits? Stacker News never takes custody of stackers' money to send it to someone else. To help new stackers get started without requiring them to attach a lightning wallet, stackers without an attached wallet will earn cowboy credits (CCs) when other stackers zap their content. Stacker News will accept CCs instead of sats for any payment on the site at a 1:1 ratio. This means new stackers can use these earned CCs to pay for posts, comments, zaps, jobs, boosts, donations or even territories but cannot withdraw them. If you need additional cowboy credits beyond what you've earned through zaps, you can always purchase them with sats at a 1:1 ratio here.

Wallets Stacker News is non-custodial. To send and receive sats, you need to attach a wallet. If you don't attach a wallet, you will send and receive CCs. How do I attach a wallet?
