Perpetual Exchange Protocol (PERC)

The Perpetual Exchange Protocol (PERC) is designed to operate as a decentralized exchange (DEX) with a unique structure known as “slabs.” Each liquidity provider is afforded the ability to manage a dedicated 10MB slab that encompasses its own matching system, risk management, and liquidity provider (LP) operations. This innovative framework enhances the efficiency and effectiveness of trading by allowing each slab to function independently while still connecting to the broader market. Notably, the protocol has been developed as an advanced fork of Anatoly Yakovenko’s Percolator, boasting production-ready infrastructure and a significant number of enhancements beyond the original design.

Core concepts integral to the Perpetual Exchange Protocol include mechanisms like Reserve-Commit trading, which balances liquidity locking with trade execution to mitigate price manipulation risks. The system’s terminology introduces unique components such as slices—specific portions of reserved liquidity—and Designated Liquidity Providers (DLP), who enjoy preferential trading conditions. Additional safeguards like the Kill Band monitor significant price shifts and prevent trades from executing under stale price conditions, while the Aggressor Roundtrip Guard (ARG Tax) deters manipulative trading strategies by imposing extra costs on specific transactions that exhibit irregular patterns.

The technical architecture of PERC comprises several specialized programs that collectively enhance its functionality. These include the Router, Slab, Automated Market Maker (AMM), and Oracle programs, each handling distinct responsibilities such as routing, order matching, and market data aggregation. The protocol utilizes a unified memory architecture to facilitate ultra-low latency trading, as well as advanced security features like capability-based access control and anti-replay protection. With cross-margin trading capabilities and a dynamic fee optimization system, the Perpetual Exchange Protocol aims to deliver a seamless and secure trading experience across various markets and liquidity slabs.
