A colleague who previously worked on Web2 development wanted to learn how to get into Web3, so I explained the underlying logic to him. To truly get started, a full-stack Web2 programmer has a lot to do: First, understand what a client looks like and how nodes synchronize data. Then, understand the general implementation of mainstream clients, such as Geth and Solana nodes. Learn the on-chain languages and frameworks of different chains, such as Solidity + Foundry and Solana's Rust + Anchor, not to mention the Move framework. Become familiar with some financial and algorithmic knowledge, such as AMMs, flash loans, and cross-chain bridges. Write smart contracts, deploy testnets, debug, and integrate Next.js with front-end libraries. Learn some contract security, contract auditing, and vulnerability testing. Honestly, in 2025, from a job search perspective, I often hear that skilled Web2 programmers can't find good jobs. However, in Web3, I've rarely seen skilled full-stack programmers struggling to find jobs... If you still have a product manager mindset and have your own ideas, there are plenty of opportunities to work independently.
