The complete offline crypto portfolio tracker — holdings, P&L, tax reports, live prices, and transaction history in one private app.
Most crypto apps want your email address, your data in their cloud, and a monthly subscription fee. CryptoVault Pro works differently. It's a single HTML file that lives on your computer, stores everything in your browser, and never sends a byte anywhere. Your portfolio stays yours.
But it's not just a tracker. CryptoVault Pro also pulls live market intelligence so you can spot what's moving before the crowd does — trending coins, the day's biggest gainers, the deepest dips, and a curated breakdown explaining exactly why each one is worth your attention right now. Portfolio management and market research in one private, offline-first app.
Total value, total invested, unrealized P&L, best performer, live allocation pie chart, and value-by-wallet breakdown — all recalculated every time you open it.
Live feed of trending coins, top 24h gainers, and biggest dips from CoinGecko. Each card shows real-time price, market cap, volume, 7-day change, and a curated "Why it's interesting" research note. Data refreshes every 48 hours automatically.
Track any coin across as many wallets and exchanges as you hold. Add quantity, average buy price, current price, and location. One click to add any Opportunities coin directly to your portfolio.
Record every buy, sell, transfer in/out, and earn/staking event with date, price per coin, fee, wallet, and notes. Full searchable history.
Organize holdings by Coinbase, Binance, Ledger, MetaMask, or any custom label. See the total USD value held in each location at a glance.
Unrealized gains and losses per coin with ROI %. Realized P&L from every sell. Net gain/loss, total fees paid, and return on investment across your whole portfolio.
Short-term vs long-term capital gains, FIFO/LIFO/HIFO cost basis, per-disposal breakdown, and net gain/loss for any tax year from 2022–2025. Print to PDF and hand it straight to your CPA.
Star any coin from the Opportunities feed to save it to your personal watchlist. Track its price movements alongside your holdings without committing to a purchase.
One-click live price fetch from CoinGecko for every coin in your portfolio. Works for 50+ major coins automatically; enter any other price manually. Cached locally between sessions.
Export your full holdings or complete transaction history to CSV in one click. Compatible with Excel, Google Sheets, TurboTax, and any crypto tax software.
The Opportunities section is what sets CryptoVault Pro apart from every other offline tracker. It connects to CoinGecko's free API and pulls the top trending coins globally, the 24-hour top gainers from the 100 largest coins by market cap, and the biggest dips — potential bounce opportunities or coins to avoid. Each card includes live price, market cap, 24-hour and 7-day change, trading volume, and a momentum score.
For 15 major coins including Bitcoin, Ethereum, Solana, XRP, Chainlink, Sui, TON, Injective, and more, CryptoVault Pro shows a hand-researched "Why it's interesting" note covering the real investment thesis — upgrade catalysts, institutional adoption, ecosystem growth, tokenomics, and risk level. For every other coin, it auto-generates a contextual market signal based on current price action. Data is cached for 48 hours so it loads instantly and respects CoinGecko rate limits. Hit Refresh any time to force a live update.
The IRS treats cryptocurrency as property (Rev. Rul. 2023-14) — every sale, swap, or disposal is a taxable event. CryptoVault Pro tracks exactly what you bought, at what price, and what you sold, then calculates your net capital gains split between short-term (ordinary income rates) and long-term (0/15/20% preferential rates). The output maps directly to Schedule D and Form 8949. Print it, email it to your accountant, or use it to self-file with confidence.
No account to create. No email required. No data ever leaves your device. Your entire portfolio — every holding, transaction, price, and watchlist entry — lives in your browser's local storage. Close the tab and it's invisible. Open it again and everything is exactly where you left it. Copy the file to a USB drive and it runs on any computer in the world with zero installation.
Tracks any coin you can name — just type the name and ticker symbol. Live price auto-fetch covers Bitcoin, Ethereum, Solana, Cardano, BNB, XRP, Polkadot, Dogecoin, Shiba Inu, Avalanche, Chainlink, Litecoin, Polygon, Stellar, Uniswap, Cosmos, Monero, PEPE, WIF, BONK, TON, Sui, Near, Arbitrum, Optimism, Injective, Hedera, VeChain, Filecoin, and 20+ more. For any coin not in the auto-fetch list, enter and update prices manually in the Price Manager.
Like all Nexior Gray products, CryptoVault Pro is a single HTML file — open it in Chrome, Firefox, Safari, or Edge and it works immediately. No installation, no account, no subscription. Buy once and use forever.
