Build a Web3 Mobile Wallet (7‑Part Live Series) — Part 1: Architecture & Setup

Build a Web3 Mobile Wallet in 7 Days — Part 1 (Live)

Can we build a functional Web3 mobile wallet in a week? In this 7‑part live series, we’ll architect and implement a wallet inspired by Phantom, MetaMask, and Rabby—fully live and free.

What you’ll learn in Part 1:
Wallet foundation: core concepts, UX flow, account model
Key Web3 primitives: keys, addresses, networks, transactions
Project setup: mobile scaffolding, state management, SDK framework strategy
Security considerations: seed handling, signing basics, threat model

Who this is for:
Developers curious about real Web3 wallet architecture
Mobile engineers exploring crypto integrations
Builders who learn best by shipping live

Series roadmap:
1) Architecture + Setup (this video)
2) Key management + seed/derivation
3) Connect networks + RPCs/providers
4) Transaction building + signing
5) Token lists + balances + portfolio
6) Swaps/NFTs + UX polish
7) Testing, hardening, and release
