What Cryptact does
- Real-time portfolio
- The Free plan covers a real-time portfolio across 34,400 coins, so tracking costs nothing. It is stated on the Free plan as well as paid ones, and the site navigation links to it; the pages do not describe what an assistant can read or do.
- MCP and CLI
- AI integration through MCP and CLI is listed on Free and in the site navigation; the pages do not describe what it exposes. A vendor claim, so import your own wallets and see how many coins remain unmatched before paying.
- DeFi and NFT identification
- Automatic identification of DeFi and NFT transactions is listed on the Free plan, alongside domestic and overseas exchange support. Domestic and overseas exchanges are both listed, which suits Japanese users trading on foreign platforms.
- API retrieval
- Basic adds automatic retrieval via API integration, so exchange data refreshes without manual uploads. Exchange data refreshes without manual uploads from Basic upward, a convenience for people with frequent trades.
- Corporate settings
- Pro adds journal entries, a fiscal year-end month setting and corporate unrealized gain and loss. Intended for company filers who need accounting entries, so individuals filing a personal return can skip it.
How Cryptact handles your data
Cryptact's privacy policy was not opened for this review, so its retention terms, hosting region and statements on model training are unverified. The pricing page states that paid plans renew automatically every year and that payments are not refundable after checkout. Basic lists data retention as a feature. The page opened names no certifications. Buyers who need documented data handling should request it from the vendor before connecting exchange APIs.
Where Cryptact falls short in practice
- Hidden results on Free. The free plan hides tax results above 50 transactions, so most active traders must upgrade to see totals. Active traders with more than 50 transactions cannot judge the product without paying, since results are not shown.
- Auto-renewal and no refunds. Paid plans renew yearly automatically and payments are non-refundable after checkout, so set a reminder before renewal. Set a reminder before each renewal date, because the pricing page offers no refund after checkout.
- Pricing page inconsistency. A Pro+ price of ￥55,000 in the comparison table has no matching plan card, and Pro Unlimited notes unspecified conditions. Ask the vendor which price applies before buying a high-volume plan.
