Gas Optimization Audit: KuCoin

Target Protocol: KuCoin (TVL: $3612.3M)

Technical Report: Gas Optimization Audit

Target: Generic EVM / Smart Contract Architecture (KuCoin EVM Infrastructure / L2 Integration)

Category: Gas Efficiency & EVM Optimization

Status: Completed

1. Executive Summary

This report evaluates standard EVM smart contract patterns relevant to high-throughput exchange infrastructure, token bridge adapters, and L2 settlement contracts. The primary objective of this audit is to identify high-impact gas optimization vectors without compromising contract security, readability, or functional correctness.

Optimizing EVM state manipulation and call data handling significantly reduces operational overhead for batch deposits, withdrawals, and bridge relay interactions on Ethereum Mainnet and Layer-2 networks.

2. Identified Gas Optimization Vectors

Vector A: Storage Layout & Variable Packing (SLOAD/SSTORE Overhead)

• Mechanism: Unoptimized state variable declarations result in redundant storage slots (32 bytes per slot), leading to excessive SLOAD (2100 gas cold / 100 gas warm) and SSTORE operations.
• Impact: High transaction overhead during state updates in registry and vault contracts.
• Optimization: Reorder state variables so that types smaller than 32 bytes (e.g., address, uint96, uint64, bool) share the same storage slot sequentially.

Vector B: Memory vs. Calldata for Read-Only Arrays

• Mechanism: Declaring function parameters (arrays, structs, bytes) with the memory keyword forces the EVM to copy payload
