Test your decentralized applications (dApps), crypto dashboards, and portfolio trackers without touching an actual blockchain or testnet. This tool instantly generates realistic ledgers containing transaction IDs, mock wallet addresses, amounts, currency symbols, and Unix timestamps.
The generator runs entirely offline in your browser, keeping your local development rapid.
Simulating blockchain ledgers
Frontend developers and off-chain data engineers need massive amounts of valid-looking data to test table pagination, number formatting, and charting libraries. Spin up hundreds of fake transactions instantly. By setting a Seed value, you can guarantee the same transaction history generates every time for your automated tests.
Using the data
Download the output as JSON to mock blockchain RPC responses, or grab the CSV to load into test databases or spreadsheet models.
