FAQ — CryptoTax wallet history converter

Question 1

Does this tool upload my wallet CSV or address history to a server?

Accepted Answer

No. Conversion runs entirely in your browser. Files stay on your device. Optional Tron history fetch calls the public TronGrid API directly from your browser; there is no upload API on this site.

Question 2

Do I need to enter a private key or seed phrase?

Accepted Answer

Never. The tool only needs public explorer CSV exports, a Tron address for optional TronGrid fetch, or saved JSON. Never paste a private key or seed into any website, including this one.

Question 3

Is this tax, legal, or financial advice?

Accepted Answer

No. It only reformats wallet history into Koinly Universal CSV or KoinX Custom File formats for import. It does not compute gains, taxes, or filing positions. Always verify imports yourself and consult a qualified professional for tax advice.

Question 4

Which chains and inputs are supported in the free browser core?

Accepted Answer

Etherscan / BscScan / Polygonscan-style CSV exports, plus optional Tron (TronGrid) history or saved JSON. Outputs are Koinly Universal CSV and KoinX Custom File (.xlsx).

Question 5

How do I import Tron USDT (TRC-20) into Koinly?

Accepted Answer

Use the free converter on this site (or the MIT core on GitLab), then import the Koinly Universal CSV in Koinly. A disclosed walkthrough is on dev.to: Import Tron USDT (TRC-20) history into Koinly with a CSV.

Question 6

What is Free vs Pro?

Accepted Answer

FREE MIT core is the same browser converter plus MIT scripts on Getly and GitLab. PRO (paid in USDC on Getly) adds multi-wallet batch, categorisation rules, spam filtering, and a monthly summary. See About for honest limits.
