# origin

Entry point for building post conditions that apply to the transaction's origin (sender). Equivalent to `Pc.principal('origin')` but uses the special `origin` keyword.

***

### Usage

```ts
import { Pc } from '@stacks/transactions';

// The transaction sender will send exactly 10,000 microSTX
Pc.origin().willSendEq(10000).ustx();

// The transaction sender will send at most 5,000 of a fungible token
Pc.origin()
  .willSendLte(5000)
  .ft('ST1PQHQKV0RJXZFY1DGX8MNSNYVE3VGZJSRTPGZGM.token-contract', 'token-name');
```

#### Notes

* Use `Pc.origin()` when the post condition should apply to the sender of the transaction without specifying a specific address.
* The builder chain is the same as `Pc.principal()`.

function origin(): PartialPcWithPrincipal;
```

***

### Returns

`PartialPcWithPrincipal`

An intermediate builder object. See `Pc.principal` for the full chain API.

## 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.stacks.co/reference/stacks.js/stacks-transactions/post-conditions/origin.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.
