Intent-Based Swap Submission Tool

WHAT IT DOES

Intent-Based Swap Submission Tool is a non-custodial tool that submits intent-based swaps, expressing a desired trade outcome for solvers to fulfill through competitive execution. It reads intent-based swap contract state, user address, token balances, swap parameters, source token address, destination token address, source amount, destination amount, slippage tolerance, intent deadline, solvers state, user's intent history, execution status, settlement state, fee structure, and solvers availability to structure the optimal intent submission operation. With a single transaction, it calls submitIntentSwap(), executeIntentSwap(), or placeIntentOrder() on the target contract, submitting a swap intent that solvers can compete to fulfill. The tool enables users to specify their desired trade outcome and let solvers compete to provide the best execution.

HOW TO USE

1. Connect your wallet (EVM-compatible).

2. Paste the intent-based swap contract address.

3. Enter the source token address, destination token address, and source amount.

4. Set the minimum destination amount, slippage tolerance, and intent deadline.

5. Review the solvers available and execution status.

6. Click "submit intent" and confirm the transaction in your wallet.

The tool automatically handles token approvals. After the transaction confirms, your intent is submitted on-chain—no centralized custody, no intermediaries. Solvers will compete to fulfill your intent at the best possible price.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH AUTO-APPROVAL

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts submitIntentSwap(), then falls back to executeIntentSwap() or placeIntentOrder() 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 approval status by checking the current allowance from storage, rather than relying on historical Approval events—because an event log proves an approval happened, not that it still stands. 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 parameters are within acceptable ranges and that the intent deadline is in the future 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 swap will execute at the optimal price due to market conditions. It cannot guarantee that swap 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 parameters are 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 intent parameters. It cannot ensure that a solver will pick up the intent. It cannot protect against loss if intent is executed at unfavorable price. It cannot verify that the intent deadline is still open. It cannot guarantee that the intent will be filled. It cannot ensure that settlement will be processed correctly. It cannot verify that the destination amount will be met.

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 and intent parameters before executing. Intent execution depends on solver availability and market conditions—submitting an intent does not guarantee execution. The tool is provided as-is; use at your own risk.
