Hashmal is an IDE for Bitcoin transaction scripts and a general cryptocurrency development toolbox. Its primary purpose is to make it easier to write, evaluate, and learn about transaction scripts.
Hashmal is intended for cryptocurrency developers and power users.
- Write scripts in human-readable form.
- Observe the stack as scripts are executed.
- See explanations of script operations as they are evaluated.
- Generate transaction scripts using templates.
- Deserialize and build transactions.
- Deserialize blocks.
- Communicate with full nodes or block explorers to retrieve blockchain data.
- Encode and decode addresses.
- See Tools > Plugin Manager in the menubar for details on what each tool does.
- You can manage tool layouts via Tools > Settings in the menubar.
- When typing opcodes, you can omit the
OP_prefix for opcodes other thanOP_1, OP_2, ...OP_16. For example,DUPandOP_DUPdo the same thing. - When editing scripts, put something in double quotation marks to ensure it's interpreted as text rather than hex data.
- You can quickly evaluate the script you're working on via Script > Evaluate in the menubar.
