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.
