一次质押多个 ERC721 NFT

[英]Staking multiple ERC721 NFTs at once

原文 2022-04-13 15:01:20 7 1 ethereum/ nft/ erc721

I have an ERC721NFT contract/collection that is already deployed.我有一个已经部署的 ERC721NFT 合约/集合。 I am asked to stake them which i did by creating a new contract and implementing the onErc721Receive function. So far so good.我被要求通过创建新合同并实施 onErc721Receive function 来抵押它们。到目前为止一切顺利。 If you send a NFT from the right collection it automatically stakes it and then let you claim your rewards or unstake your NFTs at any time.如果您从正确的收藏中发送 NFT，它会自动对其进行质押，然后让您随时领取奖励或取消质押您的 NFT。

However I am asked to implement staking of multiple NFTs at once.但是，我被要求同时实施多个 NFT 的质押。 From my understanding since the base contract was a base erc721 contract with no multiple send nor staking it shouldn't be possible.根据我的理解，因为基本合同是基本的 erc721 合同，没有多次发送，也没有下注，所以它不应该是可能的。

Is there a way to go around that and stake several NFTs at the same time?有没有办法绕过 go 并同时质押多个 NFT？
