KEYSTORE is a Telegram bot for buying and selling Mann Co. Supply Crate Keys from Team Fortress 2, an asset CS2 traders often use as a liquid way to cash out or move balance around. Beyond TF2 keys, the bot also handles USDT exchange, Steam wallet top-ups, and Telegram Stars purchases, all directly inside the chat with no separate website. The operator advertises zero-commission trades, though exact rates and limits are worth confirming in the bot itself before your first deal.
