How to export Uniswap trade history? (Tax Reporting)

Accessing Uniswap Trade Data via Blockchain Explorers

1. Uniswap operates on-chain, meaning every trade is recorded as a transaction on Ethereum or compatible Layer 2 networks like Arbitrum or Polygon.

2. Users can retrieve their trade history by searching their wallet address on Etherscan, Arbiscan, or Polygonscan.

3. Each swap triggers a transaction with input and output token amounts, timestamps, gas fees, and contract interactions.

4. Filtering for transactions involving the Uniswap Router contract (e.g., 0xE592427A0AEce92De3Edee1F18E0157C05861564 on Ethereum) helps isolate swaps.

5. Raw transaction data includes decoded logs showing exact token pair, direction of swap, and slippage—critical for accurate cost basis calculations.

Using Wallet Export Features and CSV Generation

1. MetaMask allows users to export transaction history via its portfolio tab when connected to a supported network.

2. Exported CSV files contain hash, date, status, from/to addresses, value, and token symbol—but lack detailed trade breakdowns like token in/out per swap.

3. Trust Wallet and Phantom offer similar export options, though native Uniswap trade parsing remains limited without third-party enrichment.

4. Manual CSV post-processing is often required to map each transaction to a specific Uniswap v2 or v3 pool interaction using ABI decoding tools.

5. Some users concatenate multiple exports across chains into a master spreadsheet, tagging rows by network and protocol version to avoid misattribution during tax filing.

Leveraging Tax-Specific Blockchain Analytics Tools

1. Koinly ingests wallet addresses and automatically detects Uniswap v2/v3 swaps by analyzing contract calls and event logs.

2. CoinTracker supports direct API integration with wallets and identifies liquidity provision, removal, and fee harvesting events alongside standard swaps.

3. TokenTax parses Uniswap v3 NFT positions to extract individual position openings, modifications, and closures—essential for calculating gains on concentrated liquidity.

4. These platforms generate IRS Form 8949 and Schedule D–compatible reports, including FIFO, LIFO, or HIFO cost basis methods.

5. Users must verify that imported trades match on-chain records, especially when interacting with wrapped tokens or bridged assets that may trigger false positive “buys”.

Handling Complex Uniswap v3 Position Events

1. Uniswap v3 introduces non-fungible liquidity positions, making trade history extraction more intricate than simple token transfers.

2. Opening a position emits a Mint event; modifying it emits IncreaseLiquidity or DecreaseLiquidity; closing emits Burn.

3. Each event requires parsing tick ranges, price bounds, and underlying token deposits to reconstruct entry and exit values.

4. Fee accruals are tracked separately in non-transfer events and must be treated as taxable income upon claim.

5. Failure to capture all position lifecycle events leads to underreported capital gains and misclassified income—common audit triggers noted in recent IRS guidance on DeFi protocols.

Frequently Asked Questions

Q: Can I export Uniswap trade history directly from the Uniswap interface?Uniswap’s official interface does not provide an export function. All trade data must be retrieved from blockchain explorers or third-party analytics platforms.

Q: Does connecting my wallet to a tax tool grant it trading authority?No. Reputable tax tools only read public blockchain data or use read-only wallet connections. They cannot sign or execute transactions.

Q: Are Uniswap LP token deposits and withdrawals considered taxable events?Yes. Depositing tokens into a Uniswap pool is treated as a disposal of those tokens, triggering capital gains or losses based on fair market value at time of deposit.

Q: How do I handle trades involving wrapped ETH or bridged tokens like wBTC on Ethereum?Each wrapping or bridging action is a separate taxable event. Treat the unwrapped or native version as a new asset with its own cost basis, distinct from the original token.
