"Contract code size exceeds 24576 bytes" during coverage

[Bernardo]

In #288 we've seen a warning during the coverage phase in CI. This is not urgent but deserves a look at.

This contract may not be deployable on mainnet. Consider enabling the optimizer (with a low "runs" value!), turning off revert strings, or using libraries.

Background for this. I can't believe they thought that choosing a hard coded limit was a good idea.

ethereum/EIPs#170

On the bright side, this is a good opportunity to explore some techniques to make contracts lighter.

[Alberto Cuesta Cañada]

Reading this thread makes me sad. Mostly because the amount of people impacted by this and how little concern is there for them.

Not to mention that the workarounds being proposed sound complex as hell.

hi LuckyStar0831 ,i modified the hardhat.config or the truffle instead. and i added this.hopw its works for u!

module.exports = {
  solidity: {
    version: "0.8.3",
    settings: {
      optimizer: {
        enabled: true,
        runs: 1000,
      },
    },
  },
};
