We’re building an iOS non‑custodial crypto wallet for power users. The app should generate and store private keys securely on‑device using Secure Enclave, let users switch between Ethereum, Polygon, and Solana, and show accurate token balances fetched from each network. The core experience is an Earn tab where people can browse staking pools and liquidity farming opportunities, see live APYs, and start staking from simple, trustworthy flows. Transactions must be constructed, signed on the device, and broadcast to the correct smart contracts. A clear transaction history should decode data into human‑readable details. Use MVP for presentation and manage blockchain dependencies with Swift Package Manager.
