API Traders

API traders can trade via Hyperliquid exchange endpoints using the Purrps builder code. This ensures all trades generate builder fees distributed to $DEDCAT stakers as $HYPE yield.

Purrps builder wallet:

0x038a9e6803BA93d57d562E667eFc35e6C0d2ADEF

Builder fee: 0.03% (3bps)

All trades executed with this builder code route builder fees to the DEDCAT Vault.

Getting started

We've put together a complete API example repo with working code across four SDKs: Python, Rust, TypeScript, and REST API (no SDK).

Each example approves the Purrps builder code and places a BTC limit order with the builder fee pre-configured.

GitHub: https://github.com/dedcat-inc/purrps-api-examples

Setup

Copy .env.example to .env and set your main wallet private key.

Builder fee approval requires the main wallet signature, not an agent or API wallet.
