AlchemySDKを使用してアドレスのNFT情報を取得してたんですが、メインネット上はキャッシュされてる挙動をするんです…
結局ミント後すぐに情報を再取得したい場合は自作する羽目に…😭

ERC721自作、ショップ自作、今回の件も…外部ライブラリにとことんやられてるぽこぷぅですおはようございます😭

昨日スマコンのテストが終わったのでテストネットにデプロイしてみました。まだERC721で行くか1155で行くか迷ってます…
Project #monoNoFuT はNFT保有でビジュアルノベルが遊べるってシステムなので、721かどうかはあまり関係無い…
721だと逆に独自仕様になるので複雑になってしまうんですよね…

is this 0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef event log an erc721 or erc20 transfer ?

only knowable by examining the ABI of the contract that produced it, very inconvenient for indexing

I’ve just re-synced my entire Metamask API back to 2015 to clear up a mis-matched coin and an incomplete ERC721 from 2018 that was reporting wrong. Straightforward stuff.

So on #Ethereum, you have a rapidly expanding universe. #Extensions, or #Applications to the main application or the #Blockchain which lives on computers. That's how simple this shit is. So ethereum has #Tokens which are secondary markets. And some of those tokens have become #NFTS. #ERC721 etc.

The entire purpose of nfts was also fundamentally not about "tracking jpgs back to artists" either lol - Erc721 was meant to represent digital assets. Cryptokitties was the first I believe. Not about art! Lordy!

What is ERC-721?

ERC-721 is the standard that dictates how one should create an NFT. Each ERC721 NFT must have a tokenURI field, that is an external link to a JSON file stored on an external server (and commonly are not the Ethereum blockchain!)

コンテンツの価値の付け方に価値がある、という倒錯した状況が長かった気がしますね〜
しかも各々で独自のプラットフォームを持っていて、コンテンツに対する価値の一貫性もなかったように思います(ERC721には準拠していたと思いますが)
当時はERC20など下火になってきてましたし、新しいバズワードに乗り換えた、と思われても不思議じゃないと思います〜
