Wiki route

[!info] TL;DR Embedded wallets are the key carrier of reverse disintermediation in 2025-2026 fintech — the four dominant players Privy (acquired by Stripe in 2025.06 for ~$1.1B) / Coinbase CDP / Magic / Web3Auth convert fintech incumbents’ existing customer bases into crypto entry points, enabling users to hold, transfer, and sign without awareness. The protocol foundation is the ERC-4337/7702/7715 stack.

Key facts

• Stripe acquired Privy in 2025.06 for ~$1.1B · simultaneously acquired Bridge for $1.1B ^•
• Coinbase CDP launched 2024 · onchainkit + smart-wallet integrated · reaches Coinbase’s 1 億M+ users ^•
• Magic founded 2018 · started with email magic links · later pivoted to MPC · $99/mo + usage-based pricing ^•
• Web3Auth (formerly Torus Labs): open-source + enterprise dual track · BNB Labs investment ^•
• Privy clients: OpenSea · Friend.tech · Hyperliquid + Stripe’s 5M+ merchants as potential distribution ^•

Mechanism / How it works

Four-player differentiation comparison:

Five elements of “invisible to user” UX:

• Onboarding: Google/Apple/Email single tap · TSS keys handled in backend · no seed phrase
• Signing: session key (7702/7715) with 1 -time authorisation · no popups within session
• Gas: Paymaster-sponsored (4337) · USDC payment or full sponsorship
• Recovery: distributed across multiple shares (device + cloud + server)
• Cross-chain: Hyperlane / CCIP coordinate in backend · user sees a single balance

Protocol foundation: ERC-4337 (AA SCW) + ERC-7702 (EOA → SCW temporary upgrade) + ERC-7715 (granular permissions) — combining the three yields = invisible UX + seamless upgrade + granular authorisation.

Origin & evolution

2018-2022 = MetaMask-dominant era · users actively installed wallets · self-custody of seed phrases · crypto-native boundary clearly defined. 2023-2024 = Privy / CDP / Magic pivoted to B2B SaaS · customer base expanded from dApps to fintech. 2025.06 = Stripe simultaneously acquired Privy + Bridge · a symbolic moment of fintech formally embedding crypto as an entry point. 2025.07 = AWS Bedrock AgentCore Payments selected Privy as its default (see Privy × AgentCore) · embedded wallets elevated from a crypto tool to general-purpose payment infrastructure.
