Chainstack is a managed blockchain node and RPC platform serving developers across many networks.

For Hyperliquid it runs HyperEVM JSON-RPC (mainnet and testnet, including a /nanoreth endpoint with system transactions), HyperCore /info API access, archive and debug/trace data, and dedicated full or archive nodes. It also operates a testnet faucet giving up to 1 testnet HYPE per day. Hyperliquid's docs list Chainstack for archival RPC and the testnet faucet, and the official apps page lists it under Builder tools.
