Prediction Market Payout Claimer

WHAT IT DOES

Prediction Market Payout Claimer is a non-custodial tool that claims winnings from resolved prediction market positions, completing the prediction market lifecycle. It reads prediction market payout contract state, user address, token balances, market parameters, market ID, outcome IDs, position amount, payout amount, market status, resolution time, user's position history, claim status, claim deadline, claim eligibility, user's claimed history, and payout distribution state to structure the optimal payout claim operation. With a single transaction, it calls claimPayout(), executePayoutClaim(), or submitMarketPayout() on the target contract, withdrawing winnings from a resolved prediction market position. The tool handles various payout scenarios including winning positions, partial payouts, and claim deadline verification.

HOW TO USE

1. Connect your wallet (EVM-compatible).

2. Paste the prediction market payout contract address.

3. Enter the market ID and outcome ID for your winning position.

4. Optionally specify a collateral token address (leave empty for native currency).

5. Review the market status, payout amount, claim status, claim deadline, and claim eligibility.

6. Click "claim payout" and confirm the transaction in your wallet.

The tool checks market status, claim status, claim deadline, and claim eligibility before execution to prevent failed transactions. After the transaction confirms, your winnings are transferred to your wallet—no centralized custody, no intermediaries. The prediction market lifecycle is complete.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH ELIGIBILITY VERIFICATION

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts claimPayout(), then falls back to executePayoutClaim() or submitMarketPayout() if the primary method fails—automatically adapting to different contract implementations without requiring the user to know the exact function name. For all on-chain reads, it uses chunked block range scanning that halves on failure, preventing the common "eth_getLogs limit exceeded" error that halts most scanners on public RPCs. It double-verifies payout eligibility by checking both the current claim status and claim deadline from storage, rather than relying on historical events—because an event log proves a market was resolved, not that the payout can currently be claimed. Gas estimation uses receipt.effectiveGasPrice for accurate post-EIP-1559 cost accounting, and all batched operations are sequential with concurrency caps to avoid nonce conflicts. The tool also validates that the market has resolved and that the claim deadline has not passed before execution.

WHAT IT CANNOT SEE

This tool cannot verify that the prediction market contract is legitimate or has not been compromised. It cannot detect if the market has been manipulated. It cannot ensure that payout will execute at the optimal gas price due to network conditions. It cannot guarantee that payout will succeed if the market contract is paused or frozen. It cannot verify that the contract has not been upgraded or modified. It cannot detect if the trade path is optimal or not front-run. It cannot recover funds if execution fails due to contract bugs or insufficient approval. It cannot verify that the payout amount is correct or not. It cannot predict market movements, price gaps, or flash crashes. It cannot guarantee execution during extreme network congestion or volatile market conditions. It cannot detect if the underlying oracle has been compromised. It cannot prevent the user from canceling or modifying claim parameters. It cannot ensure that the market has resolved correctly. It cannot protect against loss if payout is processed incorrectly. It cannot verify that the position is eligible for payout. It cannot guarantee that winnings will be distributed correctly. It cannot ensure that the payout amount will match expectations. It cannot verify that the claim deadline has not passed.

PLEASE NOTE

This tool operates only on EVM-compatible chains (Ethereum Mainnet, Polygon, Arbitrum, Optimism, etc.). It is non-custodial—you retain full control of your funds at all times. Always verify contract addresses, market IDs, and claim parameters before executing. Payouts are subject to claim deadlines—claims must be made before the deadline expires. The tool is provided as-is; use at your own risk.
