Payment Channel Dispute Resolver

WHAT IT DOES

Payment Channel Dispute Resolver is a non-custodial tool that challenges fraudulent channel settlements and enforces correct distribution of funds based on the latest valid state. It reads payment channel contract state, user address, token balances, channel parameters, counterparty address, channel balance, nonce state, dispute details, challenger address, dispute period, channel status, withdrawal delay, user's channel balance, settlement method, claim status, dispute deadline, and evidence data to structure the optimal dispute resolution operation. With a single transaction, it calls resolveDispute(), challengeChannelSettlement(), or executeDisputeResolution() on the target contract, submitting evidence and claiming the correct balance. The tool provides a critical safeguard against dishonest counterparties who attempt to settle a channel with an outdated or fraudulent state.

HOW TO USE

1. Connect your wallet (EVM-compatible).

2. Paste the payment channel contract address.

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

4. Enter the counterparty address and your claimed balance.

5. Provide the nonce of the latest valid state and optional evidence data.

6. Review the channel status, dispute deadline, and challenger information.

7. Click "resolve dispute" and confirm the transaction in your wallet.

The tool checks channel status and dispute deadline before execution to prevent failed transactions. After the transaction confirms, the dispute is resolved and funds are distributed according to the valid state—no centralized custody, no intermediaries. The dispute resolution process ensures that the correct party receives the appropriate funds.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH EVIDENCE VERIFICATION

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts resolveDispute(), then falls back to challengeChannelSettlement() or executeDisputeResolution() 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 dispute eligibility by checking both the current channel status and dispute deadline from storage, rather than relying on historical events—because an event log proves a settlement was attempted, not that a dispute is still valid. 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 claimed balance and nonce are within acceptable ranges and that evidence is properly formatted before execution.

WHAT IT CANNOT SEE

This tool cannot verify that the payment channel contract is legitimate or has not been compromised. It cannot detect if the counterparty has submitted a fraudulent state. It cannot ensure that dispute resolution will execute at the optimal gas price due to network conditions. It cannot guarantee that resolution will succeed if the 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 dispute evidence 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 protocol has been compromised. It cannot prevent the user from canceling or modifying dispute parameters. It cannot ensure that the counterparty will not file a counter-dispute. It cannot protect against loss if dispute is resolved incorrectly. It cannot verify that the dispute deadline has passed. It cannot guarantee that the correct state will be applied. It cannot ensure that the evidence submitted is valid.

PLEASE NOTE

This tool operates only on EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, etc.). It is non-custodial—you retain full control of your funds at all times. Always verify contract addresses and dispute parameters before executing. Dispute resolution is a serious action—only file a dispute if you have valid evidence that the counterparty's settlement is fraudulent. Disputes must be filed before the dispute deadline expires. The tool is provided as-is; use at your own risk.
