# Harvest.art - Complete Documentation > The original NFT and token tax loss harvesting service since 2021. Harvest.art helps cryptocurrency users realize capital losses on worthless or unwanted NFTs and tokens for potential tax benefits. The service has helped thousands of users collectively realize over $100M USD in losses since launching in 2021. ## Table of Contents 1. [Overview](#overview) 2. [Core Services](#core-services) 3. [How It Works](#how-it-works) 4. [Supported Assets](#supported-assets) 5. [Frequently Asked Questions](#frequently-asked-questions) 6. [Technical Details](#technical-details) --- ## Overview Harvest.art was created to solve a problem unique to the cryptocurrency space: what do you do with NFTs and tokens that have become essentially worthless? Traditional financial markets have established mechanisms for writing off losses, but crypto assets—especially NFTs—often have no liquidity and no way to sell them. Harvest.art provides a solution by purchasing these unwanted assets for a nominal amount (1 gwei), which establishes a legitimate "arms-length transaction" for tax purposes. This allows users to realize the capital loss between their original purchase price (cost basis) and the sale price (1 gwei). ### Key Statistics - Founded: 2021 - Total losses realized: Over $100M USD - Users served: Thousands - Supported chains: 5+ EVM-compatible blockchains --- ## Core Services ### 1.

Compatible wallets include MetaMask, Coinbase Wallet, Rainbow, WalletConnect-compatible wallets, and more. ### Step 2: Select Assets The platform scans the connected wallet and displays: - NFTs (ERC-721 and ERC-1155) - Tokens (ERC-20) Users select which assets they want to harvest. ### Step 3: Review Cost Basis For tax purposes, users can input or calculate their original cost basis (purchase price + gas fees + marketplace fees). ### Step 4: Execute Harvest Users approve and execute the harvest transaction: - Assets transfer to Harvest.art - User receives 1 gwei per item - User receives bid tickets (optional) - Transaction is recorded onchain ### Step 5: Documentation Users receive a transaction receipt that can be used for tax documentation, showing: - Items sold - Sale price (1 gwei each) - Transaction hash - Date and time --- ## Supported Assets ### ERC-721 (Standard NFTs) Non-fungible tokens representing unique digital items. Each token has a unique identifier. ### ERC-1155 (Multi-Edition NFTs) Semi-fungible tokens that can represent both unique and fungible items. Often used for gaming items or edition-based art. ### ERC-20 (Fungible Tokens) Standard fungible tokens. Useful for harvesting failed project tokens, airdrop spam, or tokens with no liquidity. --- ## Frequently Asked Questions ### What is tax loss harvesting? Tax loss harvesting involves selling assets that have lost value to realize capital losses. These losses can potentially offset capital gains from other investments, reducing overall tax liability. ### Why does Harvest.art pay only 1 gwei? The 1 gwei price establishes a real "arms-length transaction" while ensuring users can realize the maximum capital loss (original price minus 1 gwei ≈ original price). ### Is Harvest.art providing tax advice? No. Harvest.art provides tools and educational content only. Users should consult qualified tax professionals for advice specific to their situation. Tax laws vary by jurisdiction. ### Can I buy back the same NFT after harvesting? Assets sold to Harvest.art go to The Barn and are available for public auction. You can start an auction, but other users can bid too. Some jurisdictions have "wash sale" rules that may apply—consult a tax professional. ### What chains are supported? Currently: Ethereum, Polygon, Arbitrum, Base, and Optimism. Support for additional chains is continuously being added. ### How much does it cost? There is a flat service fee per batch of up to 500 items. The fee varies by chain (roughly 0.01 ETH or less) and covers gas costs plus service. --- ## Technical Details ### Smart Contracts All Harvest.art operations are executed through audited smart contracts deployed on supported chains.
