Welcome to Spedn’s documentation!

Spedn is a high level smart contracts language for Bitcoin Cash. It is designed for explicitness and safety:

• It is statically typed - detects many errors at compile time
• It is explicitly typed - no guessing what the expression is supposed to return
• It is purely-functional - free of side effects, the common source of bugs
• It has a familiar syntax resembling C# or Rust

Warning

Spedn is an experimental tool. It is not recommended to be used on mainnet yet. Or at least do a lot of tests on testnet first.
