Why Programmable Wallets Will Eat Embedded Wallets

Apps lock users into their own custodial or semi-custodial silos. This kills composability and creates vendor lock-in.

• User Lock-in: Assets and identity are trapped within a single app's interface.
• Fragmented UX: No portable social graph or transaction history.
• Security Theater: Relies on the app's centralized key management, a single point of failure.

Programmable wallets are self-custodial smart contracts users own. They enable a universal UX layer across all dApps.

• Sovereignty: Users control their account logic and recovery mechanisms.
• Composability: A single account interacts with Uniswap, Aave, and any new protocol seamlessly.
• Batch Power: Execute multiple actions across chains in one gas-paid transaction via bundlers.

Programmable wallets enable declarative transactions. Users approve intents ("get me the best price"), not explicit txs. This unlocks:

• Gasless UX: Apps sponsor transactions via paymasters.
• Secure Automation: Grant limited session keys for specific actions (e.g., trading on CowSwap for 24 hours).
• MEV Protection: Solvers like UniswapX and Across compete to fulfill the intent optimally.

Infrastructure players like Starknet, zkSync, and Polygon are building native AA. Aggregators like Biconomy and Stackup provide bundler/paymaster services.

• Chain-Level Integration: Native AA offers better economics and security than overlay solutions.
• Vendor-Agnostic: Users are not tied to a single wallet provider; they can switch clients.
• Enterprise Scale: Enables complex gas policies and compliance modules for institutions.

Embedded wallets measure success by user sign-ups. Programmable wallets win on user activity and retention.

• Sticky Graph: A user's on-chain identity, reputation, and assets persist across the ecosystem.
• Monetization: Fee-sharing models for bundlers, paymasters, and intent solvers create sustainable business logic.
• Network Effects: More users attract more dApps, which improves the wallet's utility in a flywheel.

The programmable wallet is the user's entry point to all of crypto. It's not a keyring; it's an OS managing identity, assets, and permissions.

• Cross-Chain Native: Built with LayerZero or CCIP for seamless omnichain presence.
• AI Agent Ready: The smart account becomes an autonomous agent that executes based on user-defined rules.
• Regulatory Clarity: Self-custodial smart accounts provide clearer compliance boundaries than opaque custodial models.

Embedded wallets (Privy, Dynamic) abstract away keys but create vendor lock-in and fragmented user states. Your app's UX is trapped in their SDK.

• Key Benefit 1: Programmable wallets (like Safe{Wallet}, Kernel, Biconomy) separate wallet logic from the interface, enabling portable user sessions.
• Key Benefit 2: They turn the wallet into a programmable session layer, allowing for batched intents, fee sponsorship, and custom security models.

Paying for every user tx is a growth killer. Embedded wallets offer limited, opaque sponsorship models.

• Key Benefit 1: Programmable accounts enable native gas abstraction via Paymasters (like Biconomy, Pimlico), cutting user onboarding cost to $0.
• Key Benefit 2: They unlock session keys for intent-based flows, allowing users to approve complex, multi-step DeFi actions (e.g., UniswapX trades, Across bridges) in one signature.

Embedded wallets are siloed endpoints. The future is cross-application user flows and aggregated liquidity.

• Key Benefit 1: A programmable wallet is a universal identity node that can interact with any app, aggregator (like CowSwap), or cross-chain messaging protocol (like LayerZero, Axelar) without re-authentication.
• Key Benefit 2: It enables delegatable authority, letting users grant specific permissions to specialized agents or solvers, creating a market for automated onchain agency.

EOA-based embedded wallets force a binary choice: convenience (custodial) or self-custody (clunky).

• Key Benefit 1: Programmable wallets are inherently non-custodial with multi-factor recovery (social, hardware), eliminating the seed phrase failure point.
• Key Benefit 2: They allow for modular security policies: daily limits, transaction guards, and multi-sig for high-value actions, all programmable per application or user cohort.
