# User Flows

These pages document the end-to-end transaction flows for each user-facing operation in the Fira protocol. Each flow includes a Mermaid sequence diagram, preconditions, relevant view functions, emitted events, and reward share formulas where applicable.

{% hint style="info" %}
All user operations go through the **FiraRouterV4** (except variable-rate lending, which interacts with the LendingMarket directly). Users must approve the relevant tokens to the router before calling.
{% endhint %}
