Abstract

The Zet Swap module aggregates liquidity across decentralised exchanges to optimise spot trade execution. It primarily serves as infrastructure support for the Zetarium ecosystem.

1. Executive Summary

Liquidity fragmentation in the DeFi ecosystem makes it difficult for users to obtain the best prices and increases transaction costs. Zet Protocol is a high-performance liquidity aggregator solution developed to solve this problem.

At the heart of the protocol lies the Zet Executor, an advanced smart contract architecture that securely and efficiently executes complex swap operations in a single atomic transaction.

2. Introduction

Decentralized Exchanges (DEXs) are the cornerstone of the blockchain ecosystem. However, each DEX operates its own liquidity pools, leading to price discrepancies across exchanges.

2.1 The Problem

2.2 The Zet Protocol Solution

Zet Protocol offers an integrated structure that:

• Finds the deepest liquidity across all supported DEXs
• Minimizes slippage through intelligent routing
• Optimizes transaction fees on behalf of the user
• Executes complex swaps in a single atomic transaction

The system primarily supports major protocols:

3. System Architecture

Zet Protocol employs a hybrid architecture. The server side handles the computational load, while the blockchain side guarantees asset security and transaction finality.

3.1 Two-Component System

ZET PROTOCOL ARCHITECTURE

USER REQUEST
"Swap 1 BNB → USDT"
        ↓
ZET API (OFF-CHAIN)
+- 1. Data Aggregation
|     • Fetch pool reserves from all DEXs
|     • Monitor gas prices in real-time
|     • Track token prices and liquidity depth
+- 2. Route Optimization
|     • Graph theory algorithms
|     • Multi-hop path discovery
|     • Slippage calculation
+- 3. Calldata Generation
      • Generate transaction data
      • Prepare Zet Executor instructions
        ↓
ZET EXECUTOR (ON-CHAIN)
+- PULL: Get tokens from user
+- APPROVE: Grant DEX permission
+- CALL: Execute swap on optimal Router
+- FLUSH: Return all tokens to user
        ↓
USER RECEIVES
USDT in wallet

3.2 Zet API (Intelligent Routing)

The server side continuously monitors blockchain data (token lists, pool reserves, gas prices). When a user initiates a swap:

3.3 Zet Executor (Smart Contract)

The Zet Executor is the muscle of the system. It is a specialized Solidity contract that manages assets with user authorization.

6. Multi-Hop Routing

6.1 Why Multi-Hop?

Sometimes the direct swap path isn't the most efficient. Multi-hop routes can provide:

• Better prices through deeper liquidity pools
• Lower slippage on large trades
• Access to tokens without direct pairs

6.2 Example

Direct Route (Higher Slippage):
ZET → CAKE (2.5% slippage, low liquidity)

Multi-Hop Route (Optimized):
ZET → USDT → CAKE (0.2% total slippage)

Result: 12.5x better execution

7. Future Vision

7.1 New Chains

7.2 Additional DEX Protocols

7.3 Cross-Chain Swaps

Future versions plan to include Cross-Chain swap features, allowing users to swap tokens between different blockchains in a single transaction.
