What is Cheetah AI?
Cheetah AI is a Web3 IDE with AI built in. It’s a code editor where you can write Solidity contracts or Solana programs, compile them, deploy them to any chain, and interact with them — all through a chat interface. No terminal commands, no deployment scripts, no browser extensions. It comes with:- A built-in crypto wallet (EVM + Solana)
- Foundry compiler and Anvil local node (bundled, no install needed)
- Anchor/Solana toolchain support
- Support for 16+ chains (Ethereum, Polygon, Arbitrum, Optimism, Base, Avalanche, BNB, Solana)
- Security auditing (Aderyn)
- AI that understands your entire codebase
Get Started — Deploy Your First Contract in 5 Minutes
Step-by-step tutorial: install, set up wallet, deploy a smart contract.
How It Works
You talk to the AI in the chat panel. The AI does the work.forge build. No anvil. No deployment scripts. No MetaMask popups.
Key Features
Built-in Wallet
Create or import a wallet. Switch between 16+ chains. Send tokens, sign messages, check balances. Works for both EVM and Solana. No browser extensions.
Smart Contract Development
Write Solidity, compile with Foundry, test with forge-std, deploy to local/testnet/mainnet. OpenZeppelin imports resolve automatically.
Solana Programs
Build with Anchor framework. Compile Rust programs, deploy to local validator or devnet. SPL token support included.
Local Blockchain
Spin up Anvil (EVM) or solana-test-validator with one command. Free gas, instant blocks, unlimited test tokens. Reset anytime.
AI Agent
The AI reads files, writes code, runs commands, and iterates on solutions. It handles multi-step tasks end-to-end while keeping you in the loop.
Security Auditing
Run Aderyn static analysis on your contracts. Detects reentrancy, access control issues, gas optimizations, and 90+ vulnerability patterns.
