# Split Tokens
|
|
|
|
> Convert pUSD into outcome token pairs
|
|
|
|
**Splitting** converts pUSD collateral into a full (position) set of outcome tokens. For every \$1 pUSD you split, you receive 1 Yes token and 1 No token.
|
|
|
|
```
|
|
$100 pUSD → 100 Yes tokens + 100 No tokens
|
|
```
|
|
|
|
## Prerequisites
|
|
|
|
Before splitting, ensure you have:
|
|
|
|
1. **pUSD balance** on Polygon
|
|
2. **pUSD approval** for the CTF contract to spend your tokens
|
|
3. **Condition ID** of the market — the condition must already be prepared on the CTF contract (via `prepareCondition`)
|
|
|
|
<Note>
|
|
If the partition is trivial, invalid, or refers to more slots than the
|
|
condition is prepared with, the transaction will revert.
|
|
</Note>
|
|
|
|
## How It Works
|
|
|
|
1. You approve the CTF contract to spend your pUSD
|
|
2. You call `splitPosition()` with the amount and market details
|
|
3. The CTF contract transfers pUSD from your wallet and mints both outcome tokens
|
|
|
|
The operation is atomic — if any step fails, the entire transaction reverts.
