Privy Session Signers + Server-Side Auto-Trading Enhancements (HyperEVM)

✅ What's New

🔐 Privy Session Signers Integration

We’ve integrated Privy Session Signers, enabling delegated transaction signing via ephemeral session keys. Users can now authorize automated actions (e.g., DCA, limit orders) without remaining actively signed in.

Behind the scenes: Session keys are securely derived and scoped per user, allowing the server to sign on their behalf with controlled permissions and expiration. This introduces a non-custodial automation layer, with no persistent private key storage on our backend.

⚙️ Server-Side Limit Orders & DCA Execution

Users can now configure limit buys/sells and DCA strategies, which are monitored and executed by our backend automatically using their authorized session signer.

• 💸 Supports price-based execution (e.g., buy at $1.20, sell at $1.80)
• 🕒 Supports time-based DCA intervals (e.g., buy every 6 hours)
• 🧠 Runs asynchronously, leveraging HyperEVM’s low-latency architecture and our batched multicall infrastructure

📡 Live Orders UI Refresh

Your orders now live-update in the Orders section without needing to refresh manually.

We’ve implemented real-time websocket sync using indexed events from on-chain execution + server mempool watchers, enabling instant status reflection.

• ✅ Pending / Filled / Cancelled status auto-refresh
• 🧾 Real-time gas usage & timestamp feedback
• 🔄 Cancel / modify orders mid-cycle (if session signer is active)
