In order to purchase NFT on Lens Protocol's SNS, I purchased Ethereum Mainnet's Polygon from Japanese yen at a virtual currency sales office and transferred it to my MetaMask.
However, the Polygon that can be used on Lens Protocol's SNS is from Polygon Mainnet, and Polygon from Ethereum Mainnet could not be used.
In order to bridge from Ethereum Mainnet to Polygon Mainnet with MetaMask, a separate Ethereum was required, so
Furthermore, I purchased Ethereum from Japanese yen at a virtual currency sales office and transferred it to my MetaMask.
However, after 0.04Eth was taken as the "authentication fee" required for Bridge, I was charged an additional "gas fee", and I did not have enough Ethereum to pay it. Of course, 0.04Eth will not be returned.
I had no choice but to give up on purchasing NFTs on Lens Protocol's SNS, and used the remaining Ethereum as "gas money" to transfer Polygon from Ethereum Mainnet to a virtual currency sales office, and also transferred Ethereum to a virtual currency sales office.
The ``gas fees'' required for remittances are quite a burden in a situation where the yen is weak, so I'm thinking of giving up on Lens Protocol.
