WHAT IT DOES
Intent Cancellation Tool is a non-custodial tool that cancels submitted intents before they are filled by solvers, removing unfilled intents from the system and releasing locked tokens. It reads intent-based swap contract state, user address, token balances, intent parameters, intent ID, source token address, destination token address, source amount, destination amount, intent deadline, intent status, user's intent history, cancellation eligibility, cancellation window, execution status, settlement state, and collateral return state to structure the optimal cancellation operation. With a single transaction, it calls cancelIntent(), executeIntentCancellation(), or submitIntentCancel() on the target contract, removing the specified intent from the system. The tool is essential for managing submitted intents and reclaiming locked tokens when an intent is no longer desired.
HOW TO USE
1. Connect your wallet (EVM-compatible).
2. Paste the intent-based swap contract address.
3. Enter the intent ID, source token address, and destination token address.
4. Review the intent status, source amount, destination amount, and cancellation eligibility.
5. Click "cancel intent" and confirm the transaction in your wallet.
The tool checks intent status and cancellation eligibility before execution to prevent failed transactions. After the transaction confirms, your intent is cancelled on-chain—no centralized custody, no intermediaries. The tokens locked for the intent are released back to your wallet.
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 cancelIntent(), then falls back to executeIntentCancellation() or submitIntentCancel() 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 cancellation eligibility by checking both the current intent status and cancellation window from storage, rather than relying on historical events—because an event log proves an intent was submitted, not that it can currently be cancelled. 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 intent ID exists and that the user has permission to cancel the intent before execution.
WHAT IT CANNOT SEE
This tool cannot verify that the intent-based swap contract is legitimate or has not been compromised. It cannot detect if the intent has been manipulated. It cannot ensure that cancellation will execute at the optimal gas price due to network conditions. It cannot guarantee that cancellation 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 intent ID is valid 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 solver network has been compromised. It cannot prevent the user from canceling or modifying cancellation parameters. It cannot ensure that the intent will be cancelled before it is filled. It cannot protect against loss if cancellation is rejected. It cannot verify that the cancellation window is open. It cannot guarantee that the intent will be removed from the system. It cannot ensure that tokens will be returned correctly. It cannot verify that the intent has not already been executed.
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, intent IDs, and cancellation parameters before executing. Intents can only be cancelled while open—already filled or executed intents cannot be cancelled. The tool is provided as-is; use at your own risk.
