如何使用uupSupgradeflable使用链链接聚合V3结界？

ChainLink的gentRegatorV3Interface.sol可以通过openzeppelin升级合同工作吗？我放置

“ PriceFeed = gentregatorv3interface（0x9326BFA02ADD2366B30BACB125260AF641031331）;“

在“初始化器{}”内部？

我希望地址“ 0x9326bfa02add2222Add2222222366b30b30b30b366b30b30b30b30b30b30b bacb1b1252260af641410af641410af64141031331” 可以在智能合约的下一个版本中升级。

已经有一种方法了吗？

谢谢你！

动机＆amp;理由
我希望想要在新令牌的智能合同中“ getLatestPrice（）”是有意义的。在部署之前，无法了解新的令牌地址。我想使用UPS代理模式下的OpenZeppelin可升级合同来更改地址。

在线上有任何示例要更新

PriceFeed = gentregatorv3interface（0x9326BFA02ADD2366B30BACB125260AF641031331）; // kovan testnet

智能合约版本2上的

？谢谢你！

我不知道如何在版本2上工作2版。 UUP升级合同。

在这里，我使用chainlink的gentregatorv3interface.sol卡住了，在OpenZeppelin Contracts Wizard上选择的每个功能：

Will Chainlink's AggregatorV3Interface.sol work with an OpenZeppelin upgradable contract?
Do I place the

"priceFeed =
AggregatorV3Interface(0x9326BFA02ADD2366b30bacB125260Af641031331);"

inside the "initializer{}"?

I would like the address "0x9326BFA02ADD2366b30bacB125260Af641031331"
to be upgradable in the next version of the smart contract.

Is there already a way to do so?

Thank you!

Motivation & Justification
I hope that it makes sense to want to "getLatestPrice()" within the smart contract of a new token.
Before deployment, there is no way of knowing the new token's address.
I would like to change the address using the OpenZeppelin upgradable contract under the UUPS proxy pattern.

Is there any example online to update

priceFeed =
AggregatorV3Interface(0x9326BFA02ADD2366b30bacB125260Af641031331); //
Kovan Testnet

on version 2 of the smart contract?

Thank you!

I have no idea how to work on version 2 of an UUPS Upgradable Contract.

建议您在升级插件中使用HARDHAT（ https://docs.openzeppelin.com/conconpellin.com/concontracts/concontracts /4.x/upgradable ）实现这一目标。当您第一次使用HardHat部署它时，它将部署代理，实施合同（即您的令牌合同）和管理合同。

请参阅此视频中的20:23：。实际上，也许可以观看整个视频，以了解如何使用OZ升级合同使用Hardhat。

然后，当您获取令牌合同地址时，将令牌合同更新为V2，将合同地址添加为状态变量，并添加一个设置器函数，使您能够在将来更新该状态变量并部署V2。您可以在[24:30]左右链接的同一视频中看到如何部署V2。
