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Polygon1、准备gashttps://www.sushi.com/swap?toChainId=137&toCurrency=NATIVE&fromChainId=42161&fromCurrency=NATIVE&amount=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 https://app.holograph.xyz/create-collection3、部署NFT4、mint NFT（建议在Avalanche链操作）5、NFT跨链OK，做完了
