Miden Playground

An interactive browser environment for learning Miden and testing smart contracts. No installation required — create a testnet sandbox, write and compile Rust account components and scripts, inspect the generated Miden Assembly (MASM), and execute transactions.

What you can do

Rust editor

Build smart contracts

Write and compile account components, authentication components, note scripts, and transaction scripts in Rust.

Compiler output

Inspect generated MASM

Review the read-only MASM output together with package exports, dependencies, and compilation errors.

Testnet sandbox

Run transactions

Create or import accounts and notes, invoke account procedures, consume notes, and inspect transactions.

When to move to a local project

The Playground is useful for guided tutorials and end-to-end experiments without local setup. Move to a miden new Rust project when you need source control, automated tests, or a custom build and deployment workflow. See your first smart contract for the handoff.
