Building a Web3 messaging app typically takes around 2 to 6 months, depending on the complexity and feature set. If you’re building a simple MVP with wallet-based login, basic end-to-end encrypted messaging, and decentralized storage, the process can often be completed in 8–12 weeks. However, as Web3 messaging app development expands to include features like group chats, media sharing, token or NFT-gated access, scalability improvements, and thorough security testing, the timeline usually extends to 4–6 months or more, largely influenced by the level of decentralization, encryption complexity, and overall user experience goals.
