Built by traders, for traders

You trade on-chain.
We crunch the numbers.

Most crypto tax tools choke on anything past a simple swap. Defitax was built from the ground up for LP farms, bonding curves, prediction markets, perps, and every weird DeFi thing you did this year. No email, no KYC, fully anonymous — sync unlimited wallets and transactions. When tax season hits, download your tax forms. Pay once per year with USDC. That's it.

We speak degen fluently

Koinly doesn't know what a bonding curve is. CoinTracker has never heard of Meteora. We built this because existing tools couldn't handle our own portfolios.

Income Tracking

LP Farms & Yield

Meteora DLMM fee claims, Raydium LP rewards, pump.fun creator fees, staking yields — all auto-classified as income at FMV. Even when Helius mislabels them.

Polymarket + Kalshi

Prediction Markets

Polymarket on Polygon, Kalshi via dFlow on Solana — bets, payouts, and expired positions are automatically tracked with correct cost basis and loss recognition.

Auto-Classified

Token Launches

Launched on pump.fun, Four.Meme, Clanker, or Virtuals? We detect the creation, track your creator fees as income, and set cost basis from your initial SOL or ETH.

Solana Native

Jupiter DCA & Perps

DCA deposits are non-taxable, each fill is a separate swap. Perp PnL is handled as realized gains. We know the difference between a deposit and a disposal.

Non-Taxable

Bridge Detection

Wormhole, Stargate, Across, deBridge — cross-chain moves are non-taxable and we treat them that way. Cost basis carries over. No phantom disposals.

Auto-Filtered

Spam & Dust Filtering

Random airdrop tokens worth $0.00? Fake approvals? We filter the noise so your report only includes real activity. No phantom taxable events.

Gas fees are baked into your cost basis and proceeds. Automatically.

ETH/WETH wraps, SOL account rent, cross-wallet self-transfers — all handled correctly. We don't just parse transactions, we understand the intent behind them.

Unlimited Plan Exclusive

Your on-chain data, explained by AI

The Defitax Agent lives inside your dashboard. Ask it anything about your transactions, cost basis, PnL, or tax classifications — it has full context on your data.

Defitax Agent

On-chain data expert

How is my SOL looking?
You have 2,072 SOL transactions since Nov 2025. Volume: 677 SOL in, 616 SOL out. Across 658 disposals, your realized P&L is -$1,155.80. 78 transactions are flagged for review — mostly spam token swaps that need reclassification.
What was my biggest win?
Your best trade: +$3,860 selling 1.56M CAPTCHA on March 25. You also had two more CAPTCHA exits that day netting +$2,370 and +$2,245. Those three trades alone made you $8,475.
Ask the agent...

Knows your entire portfolio

Ask about any asset, transaction, or time period. The agent queries your actual data — aggregates, lot inventory, P&L breakdowns — not generic answers.

Tax strategy insights

“Would HIFO reduce my tax bill?” “How are my airdrops classified?” “What counts as income vs capital gains?” — get clear, data-backed explanations.

Drill into any transaction

Paste a tx hash, ask about a specific date, or find your biggest losses. The agent pulls full details including lot assignments and cost basis breakdown.

Not a generic chatbot

Powered by Claude — trained on DeFi protocols, tax classification rules, and cost basis methods. It understands the difference between a bonding curve and a swap.

The AI Tax Agent is a data exploration tool, not a tax advisor. It helps you understand your portfolio and transaction data — always consult a qualified CPA for filing decisions.
