Ethereum smart contract frameworks and SDKs
3 smart contract frameworks and SDKs whose own docs name Ethereum, compared on price, network and the catch. Checked against each maker's own pages; last updated Oct 18, 2026.
| Tool | Best for | Price | Ethereum | Catch |
|---|---|---|---|---|
| Foundry | Fast Solidity build, test and deploy toolkit | Free (open source) | Mainnet | Built for EVM chains only; no chain-specific badges beyond Ethereum |
| Hardhat | Plugin-based TypeScript environment for EVM contracts | Free (open source) | Mainnet | Built for EVM chains only; no chain-specific badges beyond Ethereum |
| OpenZeppelin Contracts | Standard Solidity token and access-control contracts | Free (open source) | Mainnet | Solidity only; Stellar needs OpenZeppelin's separate Soroban library |
