Gas Optimization

Goal

The goal of this exercise is to optimize contracts for minimal gas usage. This assignment contains 3 tasks in form of gas optimization examples. For each task your goal is to reduce the gas usage as much as possible

Steps

• Optimize each contract in contracts/ directory by making changes in the same file

What each contract does?

• Example1
  • Stores certain variables such as day, amount and ownerAddr
• Example2
  • Stores a state variable counter. Function incrementBy takes in an array and adds each element of this array to counter variable
• Example3
  • Stores a state variable marginPercentage. Function getOwnerMargin takes in an amount and returns respective amounts for owner and sender

Evaluation

• Install all dependencies

  npm install
  

• Make changes to contracts in this directory - contract/. The tests in test/ directory should run successfully.

• Run Tests

  npm test
  

• Create a pull request from your forked repo to main branch of original repo to run the github workflow.
