Session signers allow your app to create Telegram bots or other agents that can execute transactions on behalf of users. You can use session signers to execute transactions given natural language commands from users in Telegram, or execute transactions on the user’s behalf while they are offline.

You can also configure session signers such that your Telegram bot or agent has specific permissions via policies, such that the agent can only execute certain transaction types.

At a high-level, you can use session signers to create Telegram bots and other trading agents like so.
