我个人最近对路由合约非常感兴趣，而几个月前 @jtriley2p 开源了 Lotus Router 合约源代码，该合约有一个精巧的 calldata 编码设计，虽然内部包含大量内联汇编，但是其实都并不难读。可能稍有一些 EVM 底层知识就可以看懂。 目前文章主要介绍了 Router 合约的基础执行原理，特别是如何处理回调。
Be careful with information from @OpenAI ! Today I was trying to write a bump bot for pump.fun and asked @ChatGPTapp to help me with the code. I got what I asked but I didn't expect that chatGPT would recommend me a scam @solana API website. I lost around $2.5k 🧵
🧵+12M in "stuck" crypto might be recoverable. As long as the deployer nonce on another chain is not burnt and the private key is still around. The recovery mechanism is based on CREATE opcode in the EVM. Special thanks to @pcaversaccio for help validating this finding. 1/9
今天看到一个 meme 的 mint 机制挺有意思。 它的 mint 价格不像之前的 ponzi game，随着进程一直上涨，而是记录一个 25 分钟的平均 mint 数量（averageMints）。 如果 averageMints 大，那么 mint 价格升高；反之下降。
EIP-7251 is coming up in the Pectra hardfork - will allow validator sizes between 32 and 2048. This will make everything around LST's way easier. Will also reduce bookeeping everywhere. I think in hindsight, 32 only was a suboptimal choice. Fixing forward.
The dark forest just got a lot darker. A few weeks ago, 0x991 frontran a seemingly private shezmu hack tx for 250 Eth. Today the same bot frontran a private mev blocker tx, also for 250 Eth. Someone's abusing private order flow.
A periphery contract of @AAVE is hacked due to an arbitrary call/logic error. Most user funds are SAFU 😇
