LAUNCH. 🚀 Building a great 'Connect Wallet' flow is the hardest part of Web3. We've made it simple. Introducing Wallet SDK. A development kit which gives devs access the largest catalog of wallets, from custodial to MPC to smart contracts. Details. 🧵

ZK knowledge is not necessary, we explain the ZK at a level sufficient for understanding Tornado Cash (with helpful diagrams of course). However, you should be familiar with Merkle Trees already, and pretty decent at Solidity to benefit from this. rareskills.io/post/how-does-…

Write stylistically clean solidity code. Eleven common mistakes. 1) Instead of just importing a library, import the version you are using. This makes it robust if the underlying library upgrades (which isn't rare). 2) Fix the solidity pragma if you are writing an application.

With gas prices picking up again, gas optimization skills matter. RareSkills has the ultimate resources for gas optimization: ✅ The longest and most comprehensive write-up on where to find opportunities to improve gas, the Gas Optimization Book. ✅ a bestseller on Udemy for
