How it works

From idea to deployed contract
in three steps.

01
Compose
Drag audited blocks onto the canvas or describe your contract in plain English.
02
Verify
Compile in-browser with solc. Slither scans the output before you proceed.
03
Deploy
Sign with your wallet. Contract deploys to Mainnet and is verified automatically.

AI Generation

Just describe what you want.

The AI handles architecture, inheritance, and security patterns. You focus on what the contract should do.

Features

Everything you need to ship on-chain.

AI Generation
Describe it. It builds it.
Claude Sonnet reads your prompt and generates a complete block graph. No Solidity knowledge required.
Security
Slither before every deploy.
Every contract is automatically scanned. Critical findings hard-block deployment until resolved.
Deployment
One click to Mainnet.
Deploy from the browser. Etherscan and Sourcify verification runs automatically post-deploy.
Compiler
Production-grade output.
OpenZeppelin v5 components. solc 0.8.24 with optimizer. The same stack the best teams use.
Canvas
50+ audited blocks.
Drag, connect, configure. Typed ports enforce correct wiring between components.
Auth
Non-custodial by design.
Sign In With Ethereum. No email, no password. Your keys, your contracts, your funds.
