Wash Sale Avoidance Executor

WHAT IT DOES

Wash Sale Avoidance Executor is a non-custodial tool that manages tax-loss harvesting while respecting wash sale rules by properly timing purchases and sales or selecting replacement assets. It reads wash sale avoidance contract state, user address, token balances, token positions, acquisition dates, sale dates, replacement asset, replacement date, wash sale window, position history, avoidance eligibility, fee structure, settlement state, and token approval status to structure the optimal avoidance operation. With a single transaction, it calls avoidWashSale(), executeWashSaleAvoidance(), or submitWashSaleAvoidance() on the target contract, selling positions and acquiring replacement assets in a way that respects wash sale rules. The tool helps investors realize capital losses without triggering wash sale violations.

HOW TO USE

1. Connect your wallet (EVM-compatible).

2. Paste the wash sale avoidance contract address.

3. Enter the sell token, replacement asset token, and amount to sell.

4. Provide the acquisition date (Unix timestamp) and wash sale window in days.

5. Review the avoidance eligibility and wash sale status.

6. Click "execute wash sale avoidance" and confirm the transaction in your wallet.

The tool automatically handles token approvals before execution. After the transaction confirms, the sale and replacement are executed on-chain—no centralized custody, no intermediaries. The transaction is structured to respect wash sale rules by ensuring proper timing between the sale and replacement.

TECHNICAL MECHANISM: MULTI-FUNCTION FALLBACK WITH WINDOW VERIFICATION

Unlike simple transaction builders that assume a single function signature, this tool implements a multi-function fallback strategy. It first attempts avoidWashSale(), then falls back to executeWashSaleAvoidance() or submitWashSaleAvoidance() 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 avoidance eligibility by checking both the acquisition date against the wash sale window and the replacement timing from storage, rather than relying on historical events—because an event log proves a previous sale happened, not that the current avoidance is compliant. 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 wash sale window is properly observed and that the replacement asset is not substantially identical before execution.

WHAT IT CANNOT SEE

This tool cannot verify that the wash sale avoidance contract is legitimate or has not been compromised. It cannot detect if the token positions have been manipulated. It cannot ensure that avoidance will execute at the optimal price due to slippage and market volatility. It cannot guarantee that avoidance 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 avoidance 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 any underlying token has been compromised. It cannot prevent the user from canceling or modifying avoidance parameters. It cannot ensure that the avoidance will be processed. It cannot protect against loss if avoidance is rejected. It cannot verify that the wash sale rules are correctly applied. It cannot guarantee that the tax treatment will be valid. It cannot ensure that token approvals are correct. It cannot provide tax advice. It cannot verify that the replacement asset is substantially identical. It cannot guarantee that the wash sale window is properly observed.

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, token addresses, and avoidance parameters before executing. This tool does not provide tax advice—consult a tax professional before executing wash sale avoidance strategies. Wash sale rules vary by jurisdiction and may affect the tax treatment of harvested losses. The tool is provided as-is; use at your own risk.
