LayerZero 和 Zksync 都还没发币，本文主要介绍在Zksync mint NFT 然后通过LayerZero 跨链到Matic

看下图 只需要1.3U 就可以完成 Zksync 2个txn + 交互 LayerZero，低价一鱼多吃！

1.22U

* * *

1）打开以下合约
--------

[https://explorer.zksync.io/address/0x31DCD96f29BD32F3a1856247846E9d2f95C2b639#contract](https://explorer.zksync.io/address/0x31DCD96f29BD32F3a1856247846E9d2f95C2b639#contract)

2）连接钱包后，点击mint
--------------

mint

3）根据txn hash 查询log 得到 NFT ID
----------------------------

![get nft id](https://storage.googleapis.com/papyrus_images/a84cc8388a96cf5e445223e13c6c593fe00eb966a637e815d1e9634aa772bc17.png)

get nft id

4）跨链NFT
-------

![cross chain](https://storage.googleapis.com/papyrus_images/3f7689bbc2e40962b36a5255511dd01d752ba6b6807c64f4467810f183e8e188.png)

cross chain

这里gas可以设置5xxx开头，亲测可以降低gas成功

gas2

4）去matic 查询是否NFT是否到位
--------------------

点击以下地址，输入你的钱包地址查看ERC721，发现之前的

129287 NFT 已经跨链成功
