Arbitrum now fully supported: DeFi without the Excel hassle

🚀 Intro: Arbitrum is growing faster than ever

Arbitrum is one of the fastest-growing Layer 2 networks on Ethereum. Low transaction costs, lightning-fast confirmations and a thriving DeFi ecosystem make it a firm favorite among Belgian investors.
But reporting your Arbitrum transactions correctly for your tax return is not always straightforward.

CryptoTax supports full Arbitrum wallet imports and tax reporting.
No more manual Excel files. Your entire transaction history is processed automatically according to Belgian FIFO rules.

💡 Why this matters

Many Belgian investors today use several networks at the same time: Ethereum for DeFi, Base for new dApps, Arbitrum for low fees.
Until now you had to manage that data separately, with duplicate calculations and a risk of errors.

With the new Arbitrum integration, CryptoTax combines all your EVM wallets into a single overview.
Whether you bridge, swap or yield farm, we recognize it automatically and apply the correct Belgian tax rules.

⚙️ How it works

The workflow stays just as simple as with Ethereum or Base:

1. Add your Arbitrum wallet by address or ENS name.
2. CryptoTax automatically scans all incoming and outgoing transfers, swaps, bridges, staking rewards and more.
3. We apply FIFO and Belgian rules for cost basis and gain calculation.
4. Review your annual overview and export an accountant-ready PDF report.

Everything happens fully automatically, including historical euro values via our CoinGecko-based price feed.

🌐 DeFi on Arbitrum

Arbitrum has by now grown into a DeFi hub with hundreds of protocols.
CryptoTax automatically recognizes activity at, among others:

• GMX v2 (perpetuals / trading fees)
• Uniswap v3 (pool swaps and liquidity positions)
• Radiant Capital (lending & borrowing)
• Arbitrum Bridge (bridging between Ethereum ↔ Arbitrum)

Thanks to our smart identification engine (the same technology that also supports Kraken and Base) we cover more than 99% of the tokens and protocols on Arbitrum.
Even obscure DeFi tokens are automatically converted to their correct euro values.

🔭 What's coming next

With Ethereum, Base and Arbitrum fully integrated, we offer multi-chain tax reporting.
We keep expanding so that you can analyze your full DeFi activity within one platform, without spreadsheets or manual imports.
