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 src/ directory by making changes in the same file

What each contract does?

• Storage
  • Stores certain variables such as day, amount and ownerAddr
• ArrayIncrement
  • Stores a state variable counter. Function incrementBy takes in an array and adds each element of this array to counter variable
• MarginCalculator
  • Stores a state variable marginPercentage. Function getOwnerMargin takes in an amount and returns respective amounts for owner and sender
• Lock
  • Determines if the contract is locked or not on the basis of value stored in locked variable
• Dispenser
  • Stores the ether received during initialisation
  • It has a waiting period of 3 days before the funds are dispensed to all three receivers
