Batch Sender with Tax Report Export (Optimism)

WHAT IT DOES

Batch Sender with Tax Report Export (Optimism) is a specialized DeFi and compliance tool that combines efficient batch token distribution with automated tax report generation on the Optimism network. Beyond executing a single batched transaction to multiple recipients, this tool reads the transaction receipt after confirmation, fetches USD price data, and generates a downloadable CSV tax report containing every recipient's address, amount sent, USD value at time of transfer, transaction hash, block timestamp, gas cost in native ETH, and gas cost in USD. This is ideal for airdrop coordination, payroll processing, grant distributions, and any scenario where you need to provide verifiable proof of transfer with estimated USD values for tax compliance, accounting, or financial record-keeping. The tool eliminates the manual effort of cross-referencing wallet addresses with transaction data and price feeds—after the batch sends, the tax report is automatically structured and ready for export with one click, significantly reducing administrative overhead and ensuring accurate record-keeping.

HOW TO USE

Connect your Web3 wallet to the Optimism network. Enter the ERC-20 token contract address you wish to distribute. Enter the token symbol (e.g., OP) to help with price lookups—this is used to fetch the USD price. Optionally, manually enter a USD price per token to override the automatic fetch. Paste your list of recipients in the format "address, amount" with one entry per line—amounts are in human-readable token units. The tool parses the list and calculates the total tokens to be sent. It attempts to fetch the current USD price for the token using a public price API. Review the sender contract address, fee, and contract owner for transparency. Click the send batch button, review the transaction in your wallet, and confirm. The tool executes the batched transfer, waits for confirmation, and reads the transaction receipt. It then generates a structured CSV tax report containing recipient address, token amount, USD price per token, USD value, transaction hash, block number, timestamp, gas used, gas price, gas cost in native, and gas cost in USD. A download button appears, allowing you to save the CSV file for your records.

MECHANISM: POST-TRANSACTION RECEIPT PARSING WITH USD PRICE INTEGRATION

The tool implements a two-phase workflow: batch execution followed by tax report generation. First, it executes a standard batch transfer via the shared BotGentz sender contract—reading the fee() function live, checking balance and allowance, approving the exact total, and calling batchTransferERC20. After the transaction is confirmed, the tool retrieves the full transaction receipt using the provider's wait() method. It extracts the transaction hash, block number, gas used, and effective gas price. It then fetches the block to obtain the timestamp. The tool also attempts to fetch the USD price of the token using the CoinGecko API (or falls back to a manually entered price). With all this data, the tool constructs a CSV report with headers including recipient address, amount, USD price, USD value, transaction hash, block number, timestamp, gas used, gas price, gas cost in native, gas cost in USD, and chain ID. A summary row with totals is also included. The CSV export is generated client-side using Blob and downloaded via a temporary anchor element, requiring no server interaction and keeping all data local.

WHAT IT CANNOT SEE

This tool reads transaction receipts after execution and fetches price data from external APIs, but cannot verify recipient validity, sender balance, token contract correctness, transfer pausing, blacklisting, or gas fluctuations before the transaction. It cannot guarantee that all transfers will succeed—if the batch transaction fails at the contract level, no report is generated and no partial transfers occur. It cannot account for Optimism-specific gas mechanics or L2 fee structures that might affect transaction finality. It cannot provide real-time USD pricing if the price oracle is unavailable or if the token symbol is not recognized. It cannot verify that the USD values are accurate for tax purposes or that the report meets any specific tax jurisdiction requirements—the report provides estimates based on external price data. It cannot recover from failed transactions or generate reports for failed batches. It cannot verify that the token contract uses standard decimals or symbol conventions.

PLEASE NOTE

This tool works exclusively on EVM-compatible chains and is specifically designed for Optimism. It requires the user to have sufficient native ETH for gas and sufficient distribution token balance to cover the total amount sent plus the sender contract fee. The user is solely responsible for verifying the token contract address, token symbol, recipient addresses, and amounts before signing. Always test with a small batch first to confirm the setup is correct. The tax report is generated for informational purposes and should be verified by a qualified tax professional for actual compliance. The sender contract addresses are hardcoded per chain and are publicly available for verification; no third-party custody is involved; you remain in full control of your wallet and funds at all times.
