Paste your wallet address and submit
Paste your public Arbitrum wallet address into the field and click Submit. KoinX scans the Arbitrum blockchain and imports all transactions associated with your wallet. Large wallets may take a few minutes to fully sync.
Done. KoinX imports your full Arbitrum history, classifies each transaction, and prepares everything for gains calculation and tax report generation.
Once your Arbitrum data is in, head over to Tax Reports on KoinX - your capital gains across swaps, DeFi activity, and transfers are already calculated and your report is ready to download.
Public address only - only your public 0x wallet address is required. Never share your private key or seed phrase.
Multiple wallets - if you have more than one Arbitrum wallet, repeat the integration for each address separately.
Add both chains - if you bridge between Ethereum and Arbitrum, add both wallet addresses to KoinX so bridge transfers are matched as internal movements correctly.
Do I need a separate wallet address for Arbitrum vs Ethereum?
No. Arbitrum uses the same 0x wallet address format as Ethereum. Add the address specifically under the Arbitrum integration in KoinX to capture your Arbitrum-specific transactions.
Can I connect multiple Arbitrum wallets to KoinX?
Yes. Add each wallet address separately in the KoinX Integrations section. KoinX aggregates transactions from all connected wallets for a complete tax picture.
How does KoinX handle Arbitrum bridge transactions?
Bridge transactions between Ethereum and Arbitrum are typically classified as internal transfers. Add both your Ethereum and Arbitrum wallet addresses to KoinX so it can match bridge transfers correctly and exclude them as taxable events.
Does KoinX support my country's crypto tax rules?
Yes. KoinX supports 100+ countries with dedicated report formats for India, the US, UK, Australia, Canada, Germany, and more. After importing your Arbitrum data, select your country to generate the correct report.
Is it safe to share my wallet address with KoinX?
Yes. Your public wallet address is visible on the blockchain by anyone. Sharing it does not give KoinX or anyone else access to your funds. KoinX uses it in read-only mode to import your transaction history.
KoinX is not finding any transactions for my Arbitrum wallet
Double-check the wallet address is correct and starts with 0x. Verify you selected the correct Arbitrum network - Arbitrum One and Arbitrum Nova are separate networks in KoinX.
Transaction count looks lower than expected
KoinX may still be syncing a large wallet history. Wait for the full sync to complete before checking. Also confirm you have added wallet addresses for any other networks you use such as Ethereum or Polygon.
A DeFi transaction is classified incorrectly
Some complex DeFi protocols use non-standard transaction patterns. Go to the Transactions tab in KoinX, find the miscategorised transaction, and manually assign the correct category.
Bridge transactions are showing as taxable events
Add both your Ethereum and Arbitrum wallet addresses to KoinX. It will match the bridge transfer as an internal movement between your own wallets and remove it as a taxable event.
Wrong wallet address was entered
Go to KoinX -> Integrations, remove the Arbitrum wallet, and re-add it using the correct public 0x address from your wallet app.
KoinX is showing duplicate Arbitrum transactions
Check KoinX -> Integrations for duplicate Arbitrum wallet entries and remove any extras. Each public address should only be added once.
