Introduction

Doodledapp turns visual nodes into real Solidity smart contracts. You drag, connect, and build, no code required.

Drag the divider to see both sides. The left is what you build. The right is what you get.

}
Press enter or space to select a node. You can then use the arrow keys to move the node around. Press delete to remove it and escape to cancel.

Flow Solidity

Every node maps 1:1 to Solidity. These docs walk you through the building blocks, with interactive demos you can try as you go.
