 To enhance the HyperEVM developer experience, we provide free public access to our professionally hosted Testnet RPC endpoint. Developers can use this endpoint to build Hyperliquid applications and configure it as a testnet RPC in browser wallets. For mainnet deployments, see available mainnet RPC URLs on the [Hyperliquid docs](https://hyperliquid.gitbook.io/hyperliquid-docs/builder-tools/hyperevm-tools).
