PonyHof

A privacy-first, permissioned, decentralized off-chain dark pool relay network

Problem Statement

PonyHof is a decentralized infrastructure overlay that extends the 1inch Limit Order Protocol by enabling:Permissioned, encrypted dark pools where traders share and match sensitive limit orders off-chain with cryptographic privacy.Decentralized, trust-enhanced relay using libp2p IPFS-based P2P network with encrypted routing and membership control.Reputational scoring system for relayers and traders, incentivizing reliable, censorship-resistant order propagation.Onchain settlement of orders on deployed 1inch contracts (LimitOrderProtocol & GasStationOnFill on Sepolia).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.

Solution

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