A web-based tool for inspecting and decoding Stellar blockchain transactions. Paste a transaction hash or XDR string and get a human-readable breakdown — no digging through raw JSON required.
Built by Horizoneer.
- Decodes transaction hashes into plain English — status, fee, memo, source account
- Shows operation-level details (payments, contract calls, trust lines, and more)
- Syntax-highlighted raw JSON for when you need to go deeper
- Copy to clipboard on every field — hashes, accounts, XDR strings
- Supports both Mainnet and Testnet (switchable via toggle)
- Account detail page with balances, trustlines, and recent transactions
- Full XDR decoder mode
- Shareable transaction URLs via deep linking
- Dark/light mode toggle with system preference detection
You'll need Node.js 18+ installed.
