Why the 'Wallet' Metaphor is Holding Us Back

Every interaction requires a wallet pop-up, creating ~15-30 seconds of cognitive overhead per transaction. This UX friction kills session-based applications and limits DeFi to power users.

• Abandons ~70% of potential users at the first transaction
• Makes complex multi-step DeFi strategies (e.g., looping, arbitrage) a UX nightmare
• Forces developers to design around wallet limitations, not user intent

Users declare what they want (e.g., "swap ETH for USDC at best rate"), not how to do it. Protocols like UniswapX, CowSwap, and Across handle routing, batching, and execution.

• Gasless sign-ups: Users pay with the output token, no need for native gas
• Optimal execution: Solvers compete, users get MEV-protected, better-priced outcomes
• Chain-agnostic: The intent is fulfilled across the most efficient liquidity pools and chains

Your on-chain history—creditworthiness, social graph, transaction volume—is siloed inside your wallet address. This forces reputation re-building on every new dApp and chain.

• No portable identity: A whale on Arbitrum is a ghost on Solana
• Zero underwriting data: Lending protocols cannot assess risk without over-collateralization
• Sybil vulnerability: Every app must reinvent anti-sybil checks (e.g., proof-of-humanity)

Smart accounts (ERC-4337) decouple identity from key pairs. Combined with social graphs and attestation protocols (Ethereum Attestation Service, CyberConnect), reputation becomes a composable asset.

• Session keys: Grant temporary permissions for seamless app interaction
• Portable credit scores: Lenders like Cred Protocol underwrite based on holistic on-chain history
• Sybil-resistant primitives: Dapps plug into a shared, verifiable identity layer

Holding private keys makes users targets. $1B+ is stolen annually from individuals via phishing and malware. The "be your own bank" mandate is a mass-adoption killer.

• Irreversible errors: A mistyped address or wrong network selection means total loss
• Key loss is total loss: No recourse for forgotten seed phrases
• Enterprise impossibility: Corporations cannot operate with single-point-of-failure key management

Multi-Party Computation (MPC) and institutional custodians (Fireblocks, Coinbase WaaS) split key material, enabling social recovery, policy-based approvals, and fraud monitoring.

• No single point of failure: Requires multiple parties to sign, defeating phishing
• Recoverable accounts: Use social or institutional guardians to restore access
• Enterprise-grade policies: Enforce multi-sig rules and transaction limits programmatically

The Problem: Seed phrases are a UX dead-end and a security liability. The Solution: Smart contract wallets (like Safe) enable social recovery, batched transactions, and gas sponsorship. The $50M+ in sponsored gas on networks like Polygon PoS proves demand.

• Session Keys: Enable seamless, pre-approved interactions with dApps.
• Paymasters: Let protocols or employers pay gas, removing a major friction point.

The Problem: Users are forced to become on-chain traders, manually routing swaps and managing liquidity. The Solution: Protocols like UniswapX, CowSwap, and Across solve for user intent. You declare "swap X for Y," and a solver network competes to fulfill it optimally.

• MEV Capture Redirected: Searchers' profit becomes user savings via better prices.
• Cross-Chain Native: Intents abstract away the underlying settlement layer, a core thesis behind layerzero and Chainlink CCIP.

The Problem: Monolithic wallets are feature-bloated or limited, forcing users to juggle multiple apps. The Solution: Frameworks like ZeroDev and Rhinestone enable modular, plug-in smart accounts. Developers can install 'modules' for specific functionalities like 2FA, subscriptions, or automated strategies.

• Composability as Feature: Security, DeFi, and social modules can be mixed and matched.
• Developer Primitive: Turns wallet infrastructure into a Lego block for new on-chain applications.

The Problem: Granting unlimited token approvals is a constant security nightmare. The Solution: Environments like Solana's Actions and Ethereum's Token-Bound Accounts create scoped, temporary authority. A gaming dApp gets permission to move only your in-game assets, not your entire wallet.

• Least Privilege On-Chain: Limits blast radius of any compromised component.
• Enables New Models: Facilitates subscription services, delegated trading, and compliant institutional flows.

The current model forces users to be their own sysadmins, managing keys, gas, and failed transactions. It's a UX bottleneck that caps adoption at ~10M daily active users.\n- Security Burden: Private keys are a single point of catastrophic failure.\n- Cognitive Overload: Users must understand gas, networks, and slippage.\n- Fragmented Identity: Your on-chain history is siloed across dozens of keypairs.

Shift from signing transactions to declaring desired outcomes. Let a network of solvers (like in UniswapX and CowSwap) compete to fulfill your intent optimally.\n- User Declares: 'Swap X for Y at best price'.\n- System Solves: Finds optimal route across Uniswap, Curve, 1inch via MEV-aware solvers.\n- Result: ~50% lower costs, better execution, and zero failed transactions.

Replace static keypair wallets with programmable smart accounts (ERC-4337). These are autonomous agents that can batch operations, pay gas in any token, and enforce complex security rules.\n- Session Keys: Enable seamless app interaction without constant signing.\n- Social Recovery: Move beyond seed phrases with multi-sig or biometric guardians.\n- Composability: An account becomes a programmable identity layer for DeFi and Social.

Abstract the chain itself. Users shouldn't need to know they're on Arbitrum or Base. Projects like Polygon AggLayer and zkSync Hyperchains aim for this, but the RPC layer is key.\n- Single Signer: Sign once for actions across any chain or L2.\n- Unified Gas: Pay with a single balance, abstracting away native tokens.\n- Developer Win: Build a single UX flow, not 50 chain-specific integrations.

Value accrual shifts from L1s to the layers that abstract them away. The winners will be solver networks, account abstraction SDKs, and intent discovery protocols.\n- Solver Markets: The Across and LayerZero of intent execution.\n- SDK Providers: The Privy, Dynamic, ZeroDev of embedded wallets.\n- New Primitives: Reputation systems for agents and verifiable fulfillment proofs.

Abstraction introduces trusted intermediaries: sequencers, solvers, and RPC providers. Without careful design, we rebuild the centralized web with extra steps.\n- Solver Cartels: Could collude to extract maximal MEV, negating user benefits.\n- RPC Monopolies: A single provider (Infura, Alchemy) controlling access becomes a censor.\n- Mitigation: Requires decentralized solver networks and permissionless RPC protocols.
