Deep Dive into Smart Contract Proxies: Gas Usage Comparison

This repository contains the code sample for measuring gas usages of different types of proxies used in the article, "Deep Dive into Smart Contract Proxies: CREATE vs. CREATE2, Variants, and Security Considerations".

Structure

• contracts: Comparison of four different deployment mechanisms for ERC20 tokens.
• test: Tests for contracts.
• hardhart.config.js: Hardhat configuration, including compiler optimization options.

Scripts

• yarn compile: Compile the contracts.
• yarn test: Run the tests and produce a gas usage report.

Examples

• Description:

  In this example, we deploy ERC20 using different mechanisms. This allows us to compare the deployment and usage costs associated with the different deployment patterns.

• Gas Usage for each function call

  Contract	Method	Gas
  Implementation ERC20	transfer	51375
  Clone ERC20	transfer	54053
  TUP ERC20	transfer	58676
  UUPS ERC20	transfer	56276
  FactoryImplementation	createToken	955713
  FactoryClone	createToken	184530
  FactoryTUP	createToken	642123
  FactoryUUPS	createToken	259799

• Gas Usage for contract deployments

  Contract	Gas
  FactoryImplementation	1039468
  FactoryClone	1107602
  FactoryTUP	1861538
  FactoryUUPS (Uses UUPSCompatibleERC20)	1956580
