# ActionMisc

{% endhint %}

## Functions

### BT+CT lifecycle

* **`mintBcFromToken` / `mintBcFromFw`** — Convert tokens or FW into equal BT + CT
* **`redeemBcToToken` / `redeemBcToFw`** — Recombine BT + CT back to tokens or FW

### Position exits

* **`exitPreExpToToken` / `exitPreExpToFw`** — Exit all positions (LP + BT + CT) pre-expiry. First matches BT with CT for direct redemption (cheapest path), then swaps any remaining unmatched tokens via the AMM.
* **`exitPostExpToToken` / `exitPostExpToFw`** — Post-expiry exit. Burns LP, sends BT to CT contract, redeems via `CT.redeemBC()`. CT is not burned post-expiry.

### Utility

* **`multicall`** — Batches multiple router calls via `delegatecall` to self. Each sub-call can be marked `allowFailure`.
* **`simulate`** — Executes a call and reverts with the result bytes. Used by off-chain code to preview transaction outcomes without sending a real transaction.

### Rewards

* **`redeemDueInterestAndRewardsV2`** — Collects interest from CT + rewards from FW + rewards from markets, optionally swapping reward tokens via an aggregator.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fira.money/developers/protocol-contracts/router/action-misc.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
