Gas Optimization Audit: HTX

#web3 #security #ethereum #defi

Gas Optimization Audit: HTX

Target Protocol: HTX (TVL: $4136.4M)

Gas Optimization Audit Report: HTX Protocol

Target Protocol: HTX Protocol

Chain Architecture: Ethereum Mainnet & L2 (Arbitrum / Optimism)

Scope: Smart Contract Bytecode & Core State Interaction Patterns

Focus: EVM Gas Reduction & Execution Efficiency

1. Executive Summary

This report evaluates the execution efficiency and gas footprint of smart contract patterns typical of high-TVL cross-chain liquidity and staking protocols such as HTX Protocol.

Optimizing EVM execution gas lowers friction for retail users and significantly reduces operational expenditures for automated protocol keepers, rebalancers, and bridge relayers. This audit identifies key areas where storage patterns, call data passing, and control flow can be optimized without compromising contract security or state safety.

2. Identified Gas Optimization Patterns & Vectors

A. Storage Layout & Slot Packing (State Overhead)

  • Vector: Misaligned state variables cause unnecessary SSTORE (20,000 gas cold) and SLOAD (2,100 gas cold) operations.
  • Finding: Combining smaller uint types (e.g., uint96 for balances, uint32 for timestamps, uint8 for flags) into single 32-byte storage slots drastically reduces storage reads/writes in high-frequency update functions (e.g., balance updates, fee accounting).

B. Memory vs. Calldata Passing for Read-Only Data

  • Vector: Passing complex structs, arrays, or signatures using memory forces redundant allocations and memory expansion costs.
  • Finding: Switching external function parameters from memory to calldata avoids memory copy loops, saving ~200–500 gas per array parameter.

C. Custom Errors vs. Revert Strings

  • Vector: require(condition, "Very Long Error String Here") deployment and execution overhead.
  • Finding: Deploying custom errors (error Unauthorized()) introduced in Solidity 0.8.4 uses 4-byte selectors instead of storing dynamic dynamic dynamic
