About This Video

As you all know, I’m a full-stack blockchain developer—I build dApps for Solana, Ethereum, Avalanche depending on the client, and I also audit projects. In the past couple of months, while auditing different Solana applications, I kept finding the same set of issues again and again. In this video, I break down the top 5 mistakes developers make when building Solana projects—especially SPL-token based apps like token creators—because if you ignore these now, later you’ll face serious problems when you integrate staking, airdrops, authorities, or external contracts. The first big mistake is handling token decimals in the wrong way. People don’t match on-chain decimals with the front-end logic (Web3.js conversions), and that creates critical bugs. Second is metadata: most builders either don’t understand it or structure it badly, so tokens fail to meet ecosystem standards for exchanges and integrations. Third is token supply: many projects claim “fixed supply” but keep mint/freeze/update authorities enabled, which kills trust and opens the door to manipulation. Then I talk about security mistakes—skipping validations or writing repetitive checks that bloat the program instead of using a cleaner, reusable approach. Finally, I show a real token-creator dApp we built with advanced fee collection and options to revoke authorities, so you can learn the right structure or even launch it and monetize it.
