About this app
WHAT IT DOES
Crypto Journal/Logbook helps you manually track and organize your cryptocurrency transactions. You can log each transaction with date, asset, type (buy, sell, deposit, withdraw), amount, price, total value, and optional notes. The tool stores entries locally and displays them in a clean, sortable list with the most recent entries first. This is essential for traders and investors who want to maintain a personal record of their crypto activities, track cost basis, or prepare for tax reporting. It reads the current network chain ID from your wallet provider for context, but all data is stored locally in memory.
HOW TO USE
Connect your wallet using the "Connect" button (required for network context). Select the target network (Ethereum Mainnet, Sepolia, Polygon, BSC, Arbitrum, Optimism, and testnets are supported). Fill in the transaction details: date, asset, type, amount, price, and optional notes. The total value is automatically calculated. Click "Add entry" to save it to the journal. Entries are displayed in reverse chronological order. Use the "Clear all entries" button to reset the journal. The entire operation is read-only — no transactions are signed or sent.
TECHNICAL MECHANISM
The tool stores all journal entries in a local JavaScript array. Each entry is an object with fields: date, asset, type, amount, price, notes, and auto-calculated total. Entries are sorted by date (newest first) for display. The total value is calculated as amount * price. The tool uses ethers.js v5.7.2 for network context but does not make any on-chain calls. All data is stored in memory and is lost on page reload — no data is persisted to disk or cloud.
WHAT IT CANNOT SEE
The tool cannot automatically import transactions from the blockchain. It cannot verify the accuracy of manually entered data. It cannot sync across devices or sessions. It is limited by browser memory and persistence (data is lost on page reload). It cannot generate tax reports automatically. It cannot track wallet balances or portfolio performance.
PLEASE NOTE
This tool is for educational and personal record-keeping purposes. Always verify your transaction data for accuracy. The tool does not persist any data; all state is lost on page reload. EVM chains only.
