治理契约太大，无法进行测试网部署

Question

我正在尝试部署这个使用OpenZeppelin模板创建的治理契约，它给了我错误：Warning: Contract code size is 29977 bytes and exceeds 24576 bytes (a limit introduced in Spurious Dragon). This contract may not be deployable on Mainnet. Consider enabling the optimizer (with a low "runs" value!), turning off revert strings, or using libraries.

OpenZeppelin所订立的合同如何才能变得更大？我做错什么了吗？关于如何使本合同可部署/缩小，有什么建议吗？

Answer 1

您可以在混合时编译它，而不会出现任何错误。在左边的“Solidity”选项卡中，选择“”并启用200值的优化。

那应该管用！

希望这能有所帮助！
