What problem does it solve? Setting up a machine to interact with the Hyperliquid exchange involves installing SDKs, choosing between testnet and mainnet, verifying connectivity, and securely provisioning a trade-only API wallet. This Skill walks through each step so the desk environment is correctly configured and signing keys are handled safely. ## Core Features & Use Cases - SDK Installation: Installs the Python hyperliquid-python-sdk (3.9+) or the optional TypeScript @nktkas/hyperliquid client, plus curl and jq for read-only calls. - Network & Connectivity Verification: Checks both mainnet and testnet REST endpoints with a no-key allMids call and records the result. - Secure API Wallet Provisioning: Guides the user through creating a trade-only API wallet in the Hyperliquid app and loading its key via environment variable, secrets-manager command, or a mode-600 file, never in chat or workspace files. - Readiness Check: Runs a read-only verification that the API wallet is approved for the account before the first trade is sent. - Use Case: When moving a trading desk from research to testnet, use this Skill to install dependencies, confirm connectivity, provision the API wallet through the secret store, and run the readiness check. ## Quick Start Set up this computer for Hyperliquid testnet trading, install the SDK, verify connectivity, and walk me through provisioning an API wallet.
