It really depends on your project’s goals. If you need full control over UX, security layers, and blockchain integrations (like multi-chain or NFT support), building a custom wallet is often worth the effort. It lets you tailor features like gas fee optimization, token swaps, or even dApp browsers in a way off-the-shelf wallets can’t. That said, security is everything—so using open-source frameworks as a foundation with proper audits can save time. I came across Dappfort’s breakdown on crypto wallet development and found it pretty useful for understanding how to structure the stack without missing key elements like seed phrase recovery or cold wallet integration.
