Import Arbitrum Nova (Nova Arbiscan) history into Koinly / KoinX

Last updated: 2026-10-11. This page explains how the free CryptoTax converter helps you prepare a Koinly Universal CSV or KoinX Custom File (.xlsx) from Arbitrum Nova (AnyTrust L2 / Offchain Labs) wallet history via Nova Arbiscan / nova.arbiscan.io CSV exports. Distinct from Arbitrum One (Arbiscan / arbiscan.io). It is not tax, legal, or financial advice — see Terms.

What this tool does. It converts Nova Arbiscan / nova.arbiscan.io / Etherscan-family CSV exports (normal txs, internal txs, ERC-20 / token transfers) into a Koinly Universal CSV and/or KoinX Custom File (.xlsx). You still import that file into Koinly or KoinX yourself. We are not affiliated with Arbitrum, Offchain Labs, Arbiscan, Etherscan, Koinly, or KoinX. The free converter on this site is browser-only (no upload API on our side, no private keys). The same Etherscan-family CSV path also works for Ethereum (Etherscan), BSC (BscScan), Polygon (Polygonscan), Arbitrum (Arbiscan), Base (Basescan), Optimism (Optimistic Etherscan), Avalanche C-Chain (Snowtrace), Fantom (FtmScan), Cronos (Cronoscan), Gnosis Chain (Gnosisscan), Linea (Lineascan), zkSync Era (explorer.zksync.io), Scroll (Scrollscan), Mantle (Mantlescan), Celo (Celoscan / explorer.celo.org), Blast (Blastscan), Mode (Modescan), opBNB (opBNBScan), Taiko (Taikoscan), Moonbeam (Moonscan), Metis (MetisExplorer / Andromeda explorer), Aurora (Aurorascan), Manta Pacific (Mantascan), Moonriver (Moonriver Moonscan), Fraxtal (Fraxscan), Sonic (SonicScan), Berachain (Berascan), World Chain (Worldscan), ApeChain (Apescan), Unichain (Uniscan), Abstract (Abscan), HyperEVM (HyperEVMScan), Polygon zkEVM (PolygonScan zkEVM), Sei (Seiscan), Flare (Flarescan), Songbird (Songbird Flarescan), WEMIX (Wemixscan), XDC (XDCScan), Core (Core Scan), BitTorrent Chain (BTTCscan), Monad (Monadscan), Kaia (Kaiascan), Bitlayer (BtrScan), Katana (Katanascan), Stable (StableScan), Ink (InkScan), Arbitrum Nova (Nova Arbiscan), Wanchain (Wanscan), Pharos (Pharosscan), Plasma (Plasmascan), Arc (Arcscan), Robinhood Chain (robin.etherscan.io), MegaETH (mega.etherscan.io), and similar explorers.
