Mechanism / How it works

Mainstream embedded wallets (Privy / Coinbase CDP) solve the in-dapp wallet UX, but all web/PWA wallets are still bound by the iOS Safari sandbox + Google Play / App Store 30% fee + browser push limitations. Solana judged that the wallet must be brought down to the OS layer (forming a path divergence with Embedded Wallet-Driven Fintech Disintermediation · Four-Player Structure of OS layer vs App layer). Seed Vault provides a TEE-based keystore at the Android system-service level · the private key never leaves the SoC · any dapp can request signing via a system intent · the UI is controlled by the OS to prevent phishing — the same as embedding a hardware wallet into a smartphone. MWA is an open protocol · the dapp communicates with the wallet via deep link / QR / Bluetooth · there is no need to inject JS inside the browser. The dApp Store is preinstalled on Saga/Seeker · developers can receive SOL/USDC directly with no platform fee (for USDC settlement see USD Stablecoin Interchange Market). Seeker further reinforces the native experience with the mass-market price of $450 + Helius RPC integration + the SKR token economy.

Origin & evolution

2022 Solana announced the Saga plan · in the same year Anatoly Yakovenko unveiled the SMS concept. 2023-Q1 Saga launched · early reception was polarized (crypto-native praised it + mainstream complained it was too expensive). 2024 Saga sales remained around 2 万 units, but the SMS protocol was fully adopted by Phantom / Backpack / Solflare. 2024-Q4 Seeker announced · $450 + 15 万 units pre-ordered (the conversion from Saga’s ~1/10 in sales to 5 x in pre-orders is an important proof point). 2025-Q2 Seeker mass production. 2025-2026 Solana Labs lobbied Samsung / Xiaomi for Seed Vault integration · pushing SMS standardization. Stripe + Bridge + Solana Pay integrated deeply on the merchant side · Saga/Seeker formed a closed loop on the consumer side.
