Project Description

PonyHof is a decentralized infrastructure overlay that extends the 1inch Limit Order Protocol by enabling:

  1. Permissioned, encrypted dark pools where traders share and match sensitive limit orders off-chain with cryptographic privacy.
  2. Decentralized, trust-enhanced relay using libp2p IPFS-based P2P network with encrypted routing and membership control.
  3. Reputational scoring system for relayers and traders, incentivizing reliable, censorship-resistant order propagation.
  4. Onchain settlement of orders on deployed 1inch contracts (LimitOrderProtocol & GasStationOnFill on Sepolia).
  5. Gasless fills for seamless UX to lower user friction.

This system gives 1inch and users institutional-grade privacy, programmable order logic and censorship resistance missing from current public limit order infrastructure.

How it's Made

PonyHof leverages:

  1. Backend, extended with modules for dark pool management, symmetric encryption, and reputational scoring.
  2. Libp2p-based decentralized encrypted order relay mesh, routing orders in permissioned pools off-chain.
  3. Ethers.js Sepolia JSON-RPC provider for blockchain interactions with deployed LimitOrderProtocol and GasStationOnFill contracts.
  4. A React frontend with Metamask integration to sign EIP712 limit orders off-chain, encrypt for pools and submit securely to PonyHof backend.
