Import Corn (Cornscan) 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 Corn (Maizenet) wallet history via Cornscan / cornscan.io CSV exports. Explorer brand: Cornscan at cornscan.io (Corn Maizenet, chain id 21000000 / 0x1406F40; CSV Export / Download CSV Export / exportData; downloadCSV / Export Current Records). Native gas is BTCN (Bitcorn). Corn is an L2 on Ethereum (usecorn.com). Do not confuse with the Blockscout explorer at maizenet-explorer.usecorn.com — this page cites cornscan.io only (public-address CSV path only — never private keys). It is not tax, legal, or financial advice — see Terms.

What this tool does. It converts Cornscan / cornscan.io / Etherscan-family CSV exports (normal 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 Corn, Cornscan, Etherscan, Koinly, or KoinX. The free converter on this site is browser-only (no upload API on our side, no private keys).
