  • The goal of this competition was to optimize the deployment gas cost as much as possible, no effort was made to optimizing the cost of calling contract methods
  • Note: there is a bug in the fuzz tests causing testTransfer and testWhiteTranferAmountUpdate to fail intermittently. These failures happen with the original contracts as well.

Original Instructions

GAS OPTIMSATION

  • Your task is to edit and optimise the Gas.sol contract.
  • You cannot edit the tests &
  • All the tests must pass.
  • You can change the functionality of the contract as long as the tests pass.
  • Try to get the gas usage as low as possible.

To run tests & gas report with verbatim trace

Run: forge test --gas-report -vvvv

To run tests & gas report

Run: forge test --gas-report

To run a specific test

RUN:forge test --match-test {TESTNAME} -vvvv EG: forge test --match-test test_onlyOwner -vvvv
