The Future of dApp Onboarding: No Seed Phrases

Users must manage cryptographic keys for every chain. The solution is account abstraction (ERC-4337), which separates the signer from the smart contract wallet.

• Unified Account: One social login (e.g., WebAuthn) controls a smart wallet across all EVM chains.
• Sponsored Gas: Apps pay for initial transactions, removing the need for native token onboarding.
• Batch Operations: Execute multiple actions in one user-approved session, reducing pop-up fatigue.

Users face a false dilemma: total self-custody (risky) or centralized exchange custody (censored). The solution is programmable custody via Multi-Party Computation (MPC) and intent-based systems.

• MPC Wallets (Fireblocks, Web3Auth): Private key is split, eliminating a single point of failure.
• Social Recovery: Designate trusted entities (friends, hardware) to restore access without a seed.
• Policy Engines: Set rules (e.g., 'max $1000/day') that even the user cannot override, enhancing security.

Onboarding onto one chain is pointless if assets are elsewhere. The solution is intent-centric interoperability, where the user specifies a goal and infrastructure handles the rest.

• Intent-Based Bridges (Across, LayerZero): User signs an intent ('swap ETH for SOL'), solvers compete for best execution.
• Unified Liquidity (UniswapX, CowSwap): Aggregators source liquidity across chains and L2s automatically.
• Abstracted Gas: Pay in any token; the system handles conversions and bridging fees in the background.

Provides a full-stack SDK for embedding MPC-based wallets directly into your dApp's UX. It's the go-to for apps that want to own the entire user journey.

• MPC-based key management eliminates seed phrases and enables social logins.
• Gas sponsorship and batched transactions hide blockchain complexity.
• Seamless integration with ERC-4337 for future account abstraction upgrades.

Focuses on creating portable, smart accounts that work across any EVM chain from day one, powered by MPC and ERC-4337.

• Chain-agnostic identity: A single account works on Ethereum, Base, Arbitrum, etc.
• Embedded RPC & Gas Policies: Developers control the network and fee experience.
• Recovery & Security Modules: Enables social recovery and customizable transaction guards.

Offers enterprise-grade, institutional MPC (Multi-Party Computation) as a service, enabling non-custodial wallets without seed phrases.

• Audited TSS libraries for developers to build their own wallet front-ends.
• Hardware-backed security options via integration with providers like Fireblocks.
• Focus on compliance-ready key management for regulated applications.

ZeroDev provides the SDK to create ERC-4337 smart accounts, while Pimlico supplies the bundler and paymaster infrastructure. Together, they enable gasless, batchable transactions.

• Kernel Smart Accounts: Highly modular and extensible account standard.
• Sponsorship & Paymasters: Let users pay fees in any token or enable fully sponsored sessions.
• Bundler Network: Ensures reliable and fast transaction inclusion.

Pioneered using MPC to split keys between user devices and its network, enabling familiar Web2 logins (Google, Discord) for non-custodial wallets.

• Social Login SDK: The most battle-tested path for mainstream user onboarding.
• Multi-Party Computation (MPC): No single party, including Web3Auth, holds a complete key.
• White-label solutions for enterprises and large consumer apps.

Seed phrases are the single largest attack vector, responsible for over $1B in annual losses. Users are tricked into signing malicious transactions they don't understand.

• Solution: Intent-Based Signing & Policy Engines. Protocols like Safe{Wallet} and Biconomy allow developers to set transaction policies.
• Security as a Feature: Transactions can be limited to specific dApps, amounts, or require multi-sig approvals from a trusted guardian.
• This moves security from user vigilance to programmable, on-chain rules.

MPC wallets and social recovery rely on a network of key shard holders or guardians. This creates a new attack surface: the coordinated compromise of guardians. The system's security is now the weakest link in the social graph, not cryptographic entropy.

• Single Point of Failure: Compromise of the key management service (e.g., backend of a wallet-as-a-service) can lead to mass account drainage.
• Social Engineering: Attackers target recovery guardians via phishing, moving the attack vector from code to human manipulation.
• Regulatory Seizure Risk: Centralized recovery entities become legal choke points for asset freezing.

Systems like UniswapX and CowSwap that abstract gas and routing create opaque transaction flows. Users sign high-level intents, delegating execution to a network of solvers or fillers. This introduces MEV extraction and front-running risks at the solver layer.

• Malicious Solver Networks: A dominant solver can censor, reorder, or extract maximal value from every user intent.
• Intent Mismatch: A solver could fulfill an intent in a technically valid but user-hostile way (e.g., extreme slippage on an obscure DEX).
• Lack of Slippage Controls: Abstracted UX often hides granular parameters, leaving users exposed.

Account abstraction enables seamless asset movement across chains via bridges like LayerZero and Across. The smart account itself becomes a cross-chain entity, multiplying the attack surface. A vulnerability in the account's signature logic or validation on one chain can compromise assets on all chains.

• Unified Attack Surface: A single bug in the account's entryPoint or signature aggregator can be exploited across every chain it's deployed on.
• Bridge Trust Assumptions: Users must now trust the security of multiple bridging protocols and their oracles/relayers, not just their key.
• Complex State Synchronization: Managing nonce and session keys across heterogeneous chains introduces novel race conditions.

Social recovery and MPC wallets often use on-chain registries for guardians or key shards. This creates a public, immutable map of social connections and account relationships. Chain analysis firms can deanonymize users by mapping guardian networks with higher accuracy than EOAs.

• Social Graph Exposure: Your wallet's recovery guardians are permanently linked to your address on-chain.
• Behavioral Fingerprinting: Abstracted transactions from solvers create unique, traceable patterns despite using stealth addresses.
• Data Availability: All account logic and upgrade paths are public, allowing attackers to profile and target specific account implementations.
