他们如何在不更改地址的情况下升级 WMATIC/WPOL 合约？

Question

大家好，我一直在努力了解 WMATIC 到 WPOL 的迁移是如何处理的. 具体而言，我很困惑他们在无法升级时如何更改合约 0x0d500b1d8e8e8ef31e21c99d1db9a6444d3adf1270 和 0x0000000000000000000000000000001010 的代号和名称. 他们是如何设法保持相同的合约地址但又更新了不可变的合约状态的？我读了一些关于 PIP-45 的文章，注意到了一些关于网络硬分叉的内容. 就像它提到的那样，这个变化是通过硬分叉实现的吗？

The upgrades for the WMATIC to WPOL migration were indeed achieved through a hardfork, specifically the Ahmedabad hardfork. This process allowed for the changes to be made while keeping the contract addresses the same. You can check out more details about the changes in this GitHub link.

Yes, these kinds of changes typically involve a network hardfork which allows for modifications in the system contracts without altering the actual contract addresses. This method aligns with how network upgrades or changes in immutable contracts are usually handled via governance proposals and subsequent implementations during a hardfork.
