Prediction Market Dispute Bond Poster

WHAT IT DOES

This tool enables prediction market participants to post dispute bonds to challenge market resolutions. In prediction markets, disputes arise when participants believe a market resolution is incorrect. Posting a dispute bond initiates a challenge process, requiring the bond to prevent frivolous disputes. It connects to your wallet and reads the prediction market contract address, market ID, bond amount, dispute reason, bond status, dispute history, and timestamps. The tool signs and submits transactions to post dispute bonds, challenge market resolutions, update bond status, record dispute metadata, and emit dispute events.

HOW TO USE

1. Connect your wallet using the wallet bridge (supports MetaMask, WalletConnect, and other EVM-compatible wallets).

2. Select the target network that matches your prediction market contract deployment.

3. Enter the prediction market contract address and the market ID, then click "load contract" to initialize the connection.

4. Click "fetch dispute status" to retrieve the current bond status and dispute history.

5. Review the bond status — if a dispute is already pending or resolved, you may not be able to post a new bond.

6. Enter the bond amount (in native token) and a detailed dispute reason explaining why you are challenging the resolution.

7. Click "validate bond" to verify that the amount is valid and the market is open for disputes.

8. Click "check dispute history" to view the complete history of disputes for this market.

9. Review the bond amount, dispute reason, and bond status before executing.

10. Click "post dispute bond" to sign and submit the transaction that posts the bond and initiates the dispute process.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with any EVM-compatible prediction market contract that implements a standard dispute interface (getBondStatus(uint256) view returns (uint8), postDisputeBond(uint256, string) external payable, getDisputeHistory(uint256) view). The postDisputeBond function accepts a bond amount in native tokens (payable) and a string describing the dispute reason. The contract validates that the market is in a resolvable state, the bond amount meets the minimum requirement, and no active dispute exists. The bond is held in escrow until the dispute is resolved. The getBondStatus view returns the current status (none, pending, resolved, rejected), allowing users to track the dispute's progress. The getDisputeHistory view returns an array of timestamps, poster addresses, and reasons, providing a complete audit trail of all disputes. Transaction handling follows EIP-1559 gas price calculations using receipt.effectiveGasPrice for accurate cost reporting. Dispute metadata is recorded both in the contract's history and locally for the user's reference.

WHAT IT CANNOT SEE

This tool operates purely on-chain and cannot verify off-chain dispute validity — it does not check whether the dispute is factually correct or based on accurate information. It cannot validate dispute reason — the tool cannot confirm that the reason provided is legitimate or supported by evidence. It cannot detect frivolous disputes — the tool cannot identify disputes that are submitted without merit or in bad faith. It cannot ensure fair resolution — the tool does not verify that the dispute resolution process is unbiased or that the outcome is correct. The tool also cannot verify that disputes are legitimate — it relies on the market's dispute resolution mechanism and does not independently verify dispute claims.

PLEASE NOTE

This tool works exclusively with EVM-compatible blockchain networks (Ethereum, Polygon, Arbitrum, Optimism, Base, etc.). It requires the prediction market contract to implement the dispute interface described above. All transactions incur gas fees paid by the connected wallet. The tool maintains no persistent storage — all state is refreshed from the blockchain on each session. Posting a dispute bond is a significant financial commitment — ensure you have a valid reason to dispute the resolution and that you understand the bond forfeiture conditions. The bond may be forfeited if the dispute is resolved against you. Consider reviewing the market's dispute rules and resolution criteria before posting a bond. Always test on a testnet first and verify that the dispute process works as expected.
