Raw

Mystic DEX

Allow verified humans to perform encrypted trades and retain privacy from any source chain.

This was made possible with the integration of Fhenix, Hyperlane and WorldCoin into a single all-encompassing, privacy-preserving solution.

Features

  • Verified Proof of personhood using WorldID on the Mytic DEX UI
  • Cross-Chain transfers using custom Hyperlane Warp Routes
  • End-to-End encrypted swaps using Fully Homomorphic Encryption (FHE) from Fhenix

In the end-to-end flow in Mystic DEX, the amounts swapped by the user is fully encrypted. This has a number of benefits such as MEV mitigation, on-chain privacy and user sovereignty.

Repository Structure

This repo is comprised of three packages, foundry, hyperlane,nextjs foundry - contains all smart contracts and deployment scripts for application logic residing on Base Sepolia and Fhenix. This includes AMM and Yield Bearing Vaults. hyperlane - contains all the hyperlane configurations for the warp route and core contracts to interoporate between chains. This was generated from Hyperlane CLI nextjs - Contains the front end code to run the application including world ID integration

Improvements

  • Add Account Abstraction to source chain interactions
  • Slippage improvements / customisability on Fhenix AMM
  • Deploy entrypoint contracts to more supported chains
  • Increase number of relayers / verifiers on Hyperlane warp routes
  • Add zk entrypoint to obfuscate user interactions (e.g. Railgun)
  • Add user address sanction screening to prevent bad actors (e.g. Chainalysis / Elliptic)

Verified Contracts

HOW TO NEXTJS

To build and run:

npm install && npm run dev

HOW TO FOUNDRY

install npm packages

npm install

re-map dependencies

forge remappings

re-build project

forge build

run all tests

forge test -v

deployment scripts can be found in ./script, shell scripts are used for changing state and deploying the custom vault contracts

HOW TO HYPERLANE

  1. use hyperlane cli to generate and deploy hyperlane onto new chains.
  2. create a warpe route after successful deployment

Test a hyperlane transfer of USDC from orign to src, result of this test are

  • funds deposit into vault
  • usdc synthetic token minted
  • sends encrypted token to end user
  • end user reccieved yield bearing vault token

make sure to use the private key used to deploy the core contracts ie relayer, mailbox, router

command:

hyperlane send transfer
