# Claimr
Claimr maps Twitter accounts to Solana addresses. Look up any handle and get a deterministic address that the account owner can withdraw from after authenticating with Twitter.
The primary use case is tribute tokens. Launch a token on Pump.fun with a Twitter creator's Claimr address, and trading fees accumulate until they decide to claim them.
## Overview
Pump.fun requires a creator address when launching a token. Most Twitter personalities don't have a public Solana wallet. Claimr solves this by deriving a unique address from each Twitter account's numeric ID.
```
Token trades on Pump.fun
↓
Fees go to creator vault
↓
Anyone triggers collection → moves to Claimr PDA
↓
Owner logs in with Twitter → withdraws to their wallet
```

## 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.claimr.app/readme.md?ask=&goal=
```
`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.
