Overview
A session key is a short-lived key that authorizes limited actions for a dapp, improving usability and reducing risk. It lets users grant temporary permissions without signing every transaction. It is enabled by account abstraction.
How It Works
A user authorizes a session key with specific limits, such as spending caps or a duration. The dapp uses the key to sign actions within those limits. This reduces friction and exposure.
Why It Matters
Session keys make dapps feel like web apps while preserving control. They reduce transaction fatigue and improve onboarding. They are a key usability feature of Smart Accounts.
