# LayerZero交互：用Holograph进行NFT跨链教程

### 思路

1、如果Avalanche和Polygon链上没有AVAX和MATIC的话，用sushi 的Cross Chain从OP或者ARB链跨点过去，大概需要0.1AVAX和0.55MATIC，sushi 的Cross Chain swap底层也是LayerZero的技术，相当于交互了

2、在Holograph上进行NFT跨链，建议从Avalanche链跨到Polygon

### 1、准备gas

下面这两个图是我做完之后 Avalanche链和Polygon链上花的gas（Avalanche 上花了差不多1.8刀，polygon 上花了0.51刀，仅作参考）

### 2、创建NFT

建议选择 Avalanche 链创建

### 3、部署NFT

### 4、mint NFT（建议在Avalanche链操作）

### 5、NFT跨链

OK，做完了
