I’ve spent the last year building the tool I wanted when learning raw transactions:
a visual, node-based editor where you can drag-and-drop predefined nodes on canvas to build Bitcoin transactions from scratch.
What you can do today in raw₿it- Build raw Bitcoin transactions visually by connecting nodes on a canvas
- See the exact Python code running behind every single calculation node
- Step through script execution and watch the stack mutate at each opcode
- Change amounts, locktimes, scripts and instantly see preimages, signatures, witnesses, TXID/WTXID update
- Multi-tab workspace, full undo/redo, dark mode, local save/load and shareable flows, testnet/mainnet/regtest switch
- Comes with 10 hands-on lessons (P2PKH, multisig, timelocks, SegWit, payment channels, etc.) — all transactions broadcast to testnet for verification. More lessons coming soon.
Privacy and Scope- Completely open-source and freely available online.
- Hosted version: calculations run on a minimal backend (rate-limited, no data stored).
- Local install: 100 % offline, no network needed
Designed primarily as an educational tool — not intended for managing real funds.
