💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill enables fully private limit orders on Uniswap V4, preventing MEV exploitation and strategy leakage by using Fully Homomorphic Encryption (FHE).

Core Features & Use Cases

  • Encrypted Order Parameters: Trigger prices and order types remain hidden on-chain.
  • MEV Resistance: Protects against front-running and sandwich attacks on limit orders.
  • Uniswap V4 Integration: Works as a native hook within the Uniswap V4 ecosystem.
  • Use Case: Place take-profit or stop-loss orders without revealing your strategy to the network, ensuring fair execution and preserving trade alpha.

Quick Start

Use the Susanoo skill to create a private limit order for your desired trade.

Frequently Asked Questions about Susanoo (Janus): Encrypted Limit Order Hook for Uniswap V4

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I place private limit orders on Uniswap V4?

You can place private limit orders on Uniswap V4 by encrypting trigger prices and order types using Fully Homomorphic Encryption. This keeps your trading strategy hidden on-chain while executing orders atomically through native Uniswap V4 hooks.

How does FHE prevent MEV on decentralized exchange limit orders?

FHE prevents MEV by encrypting limit order trigger prices and types before they reach the blockchain. This cryptographic hiding stops front-running bots from seeing your strategy, protecting against sandwich attacks and strategy leakage.

Can I hide take-profit and stop-loss trigger prices on-chain?

Yes, you can hide take-profit and stop-loss trigger prices on-chain by using Fully Homomorphic Encryption. The Fhenix Network processes this encrypted data, allowing the protocol to execute trades atomically without revealing your strategy alpha.

Does Uniswap V4 support encrypted order parameters for MEV protection?

Uniswap V4 supports encrypted order parameters for MEV protection through its native hooks architecture. By integrating Fhenix Network FHE, the hook validates encrypted trigger prices and order types to ensure fair execution without strategy leakage.

What is the best way to execute atomic limit orders without front-running?

The best way to execute atomic limit orders without front-running is using a Uniswap V4 hook with FHE. This approach encrypts trigger conditions on the Fhenix Network, ensuring the protocol executes orders atomically while fully resisting MEV exploitation.
