Split Tokens

Convert USDC.e into outcome token pairs

Splitting converts USDC.e collateral into a full (position) set of outcome tokens. For every $1 USDC.e you split, you receive 1 Yes token and 1 No token.

$100 USDC.e → 100 Yes tokens + 100 No tokens

Prerequisites

Before splitting, ensure you have:

USDC.e balance on Polygon
USDC.e approval for the CTF contract to spend your tokens
Condition ID of the market — the condition must already be prepared on the CTF contract (via prepareCondition)

If the partition is trivial, invalid, or refers to more slots than the condition is prepared with, the transaction will revert.

How It Works

You approve the CTF contract to spend your USDC.e
You call splitPosition() with the amount and market details
The CTF contract transfers USDC.e from your wallet and mints both outcome tokens

The operation is atomic — if any step fails, the entire transaction reverts.

Function Parameters

USDC.e (Bridged USDC) contract address: `0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174` Always `0x0000...0000` (32 zero bytes) for Polymarket markets The market's condition ID, available from the Markets API Array of index sets: `[1, 2]` for binary markets (Yes = 1, No = 2) The amount of collateral or stake to split. Also the number of full sets to receive.

Next Steps

Convert token pairs back to USDC.e Place orders using your newly split tokens
