Functions:

solidity
function redeemPositions(address collateralToken, bytes32 parentCollectionId, bytes32 conditionId, uint256[] indexSets) external;

Typical Flows

Redeem — 1 tx:

1.Verify event resolved via Polymarket API or on-chain oracle
2.redeemPositions(collateral, parentCollectionId, conditionId, indexSets) on CTF Exchange

Route: standard markets → CTF Exchange; negated-risk markets → Neg Risk CTF Exchange.

Policy Controls

•Losing positions are worthless: Tokens on losing side return nothing on redemption.
•Call after resolution only: Reverts if event not yet resolved.
•Pact expiry does NOT close positions: Conditional tokens remain in wallet until explicitly redeemed.
•Not applicable for: unresolved markets — call reverts until event resolution; losing conditional token positions
•Testnet (AMOY): No real value; use Amoy faucet for test MATIC and USDC. ctf_exchange differs from mainnet (0xdFE02...). USDC address differs from mainnet (0x9c4e... vs 0x2791...).
•Partial reference: use web search for unlisted tokens, contracts, parameters, or up-to-date addresses
