Functions:

solidity
function balanceOf(address account, uint256 id) external view returns (uint256);
function redeemPositions(address collateralToken, bytes32 parentCollectionId, bytes32 conditionId, uint256[] indexSets) external;

Typical Flows

Portfolio monitoring — scheduled off-chain:

1.Enumerate all held conditional token positions via CTF ERC1155 balanceOf queries
2.For each position, fetch current odds from CLOB API and resolution status from Gamma API
3.Compute per-position P&L: current_value - cost_basis

Auto-redemption — 1 tx per resolved market:

4.Filter positions where event has resolved
5.For winning positions: redeemPositions(collateral, parentCollectionId, conditionId, indexSets) on appropriate exchange
6.Log: {market, outcome, payout, cost_basis, realized_pnl}

Consolidated reporting:

7.Aggregate: total invested, total redeemed, open exposure, unrealized P&L, realized P&L

Policy Controls

•Batch redemption gas: Multiple redemptions in sequence; ensure sufficient MATIC for gas.
•Exchange routing per position: Each position must route to the correct exchange (CTF vs Neg Risk CTF); wrong routing = revert.
•Stale odds data: Odds shift rapidly near resolution; P&L snapshots are approximate until settlement.
•Losing positions: Tokens on losing side return nothing; do not attempt redemption on losing outcomes.
•Policy denial: Redemptions are contract calls; ensure pact covers exchange contracts.
•Related recipes: use polymarket-research-polygon for market discovery, polymarket-trading-polygon for order execution, polymarket-settlement-polygon for redemption
•Not applicable for: placing new prediction market orders — use polymarket-trading-polygon; testnet operations — use Amoy testnet recipes
•Partial reference: use web search for unlisted tokens, contracts, parameters, or up-to-date addresses
