The Future of Account Abstraction Requires New Optimization Paradigms

Bundlers default to the highest-paying paymaster, creating a centralized choke point vulnerable to censorship and MEV extraction. This reintroduces the trusted intermediaries AA sought to eliminate.

• Risk: Single paymaster can censor or front-run user operations.
• Cost: Paymaster margins add a hidden tax, often 5-15% on top of base gas.
• Solution Path: Decentralized paymaster pools and intents-based routing (e.g., UniswapX, CowSwap).

Users must hold native gas tokens on every chain for AA operations, negating the 'chain-agnostic' wallet promise. This creates capital inefficiency and UX friction.

• Inefficiency: $10B+ in capital locked across chains just for gas.
• Friction: Manual bridging for gas kills session keys and batched intents.
• Solution Path: Universal gas tokens via canonical bridges or meta-transaction relays (e.g., LayerZero, Axelar).

Shift from transaction execution to outcome fulfillment. Let specialized solvers compete on gas optimization, bundling, and routing, paying them from saved surplus.

• Efficiency: Solvers achieve ~30-50% gas savings via optimized routing & batching.
• UX: User signs a 'what' (intent), not a 'how' (transaction).
• Entities: Anoma, SUAVE, UniswapX are pioneering this paradigm.

Merge bundling and paymaster logic into a single, verifiable entity. This eliminates coordination overhead and enables true gas abstraction via batch-level sponsorship.

• Speed: Removes ~200ms of RTT between separate services.
• Cost: Enables subsidized gas models for apps without middleman fees.
• Architecture: Requires a new standard (beyond ERC-4337) for fused operators.

Extend session keys beyond dApp permissions to include dynamic gas policies. Wallet sets rules (e.g., 'spend up to 0.01 ETH on gas across these chains for 24h').

• Control: User-defined budgets prevent infinite spend exploits.
• Abstraction: Enables true 'gasless' feel for defined sessions.
• Security: Policies are enforced at the smart account level, not by a third party.

Allow paymasters and solvers to hedge volatile gas costs via on-chain futures. This stabilizes sponsorship costs and enables predictable subscription models.

• Stability: Enables fixed-fee 'gas plans' for users, like mobile data.
• Liquidity: Creates a new DeFi primitive for gas risk markets.
• Pioneers: Early concepts visible in Gasless, Biconomy, and EIP-4337 ecosystem proposals.

Paying for gas in the native token is a fundamental adoption blocker. Sponsored transactions and paymasters are a band-aid, not a solution, as they shift the cost burden to dApps and create unsustainable subsidy models.

• Key Insight: True abstraction requires decoupling payment from execution, moving to a model where users pay in any asset.
• Key Benefit: Enables "gasless" onboarding for billions of non-crypto users.
• Key Benefit: Unlocks viable business models for dApps via fee abstraction.

Instead of specifying complex transaction paths, users declare a desired outcome (e.g., "swap X for Y at best rate"). A network of solvers competes to fulfill it optimally.

• Key Insight: Separates declaration from execution, enabling MEV capture and redistribution to users.
• Key Benefit: Optimal execution across liquidity sources via solver competition.
• Key Benefit: Improved privacy and resistance to frontrunning via batch auctions.

Bridging assets and managing multiple wallets across chains is a UX catastrophe. Current AA wallets don't solve the fundamental issue of chain abstraction.

• Key Insight: Users think in terms of assets and actions, not chains. The chain should be an implementation detail.
• Key Benefit: Unified liquidity perception across Ethereum L2s, Solana, and beyond.
• Key Benefit: Single transaction flows that orchestrate actions across multiple chains.

A new stack is emerging where a single entry point (a smart account) can initiate actions that are settled via secure cross-chain messaging, with execution handled by specialized verifiers.

• Key Insight: The smart account becomes the universal portofolio, with messaging layers like LayerZero as the nervous system.
• Key Benefit: Atomic composability across chains, moving beyond simple asset bridges.
• Key Benefit: Security aggregation via decentralized verification networks.

Social recovery and multi-sig are improvements, but they add latency and complexity. The private key, whether split or not, remains a cryptographic secret that can be lost or stolen.

• Key Insight: The future is programmatic security—replacing static keys with dynamic, context-aware authorization policies.
• Key Benefit: Real-time risk scoring can block suspicious transactions before signing.
• Key Benefit: Automated recovery flows that don't require a 7-day waiting period.

Next-gen account SDKs are embedding policy engines that evaluate transaction requests against user-defined rules (spending limits, DApp allowlists, time locks) before execution.

• Key Insight: Security shifts from key protection to intent verification.
• Key Benefit: Fine-grained permissions enable new use cases like corporate treasuries and child accounts.
• Key Benefit: Proactive threat prevention via integration with threat intelligence feeds.

Sponsored transactions via paymasters (ERC-4337) add ~40k gas overhead per user operation, making micro-transactions and high-frequency social apps economically unviable.

• Key Benefit: Native gas abstraction via EIP-7702 or chain-level sponsorship cuts verification overhead.
• Key Benefit: Batched paymaster approvals across sessions (like Biconomy) can amortize costs across 1000s of ops.

Current UserOperations are low-level calldata blobs. Future AA must shift to declarative intents, letting specialized solvers (like UniswapX or CowSwap) compete on execution.

• Key Benefit: Solvers optimize for MEV capture, potentially subsidizing 100% of user gas.
• Key Benefit: Cross-chain intents natively enabled via solvers like Across and layerzero, abstracting bridge complexity.

Every new smart account creates persistent on-chain state. At scale (millions of accounts), this cripples node sync times and increases RPC latency for everyone.

• Key Benefit: Ephemeral accounts or Particle Network's MPC-based L2s keep state off-chain, pushing only final proofs.
• Key Benefit: Stateless clients via Verkle trees can validate without storing full account state, a Ethereum roadmap priority.

Generic L1s are suboptimal for AA. Purpose-built L2s and app-chains (like Starknet or zkSync) can bake AA primitives into the protocol, removing the need for a separate EntryPoint contract.

• Key Benefit: Native account abstraction enables single-transaction social recovery and session keys at the VM level.
• Key Benefit: Custom gas markets allow L2 sequencers to internalize and subsidize AA operations, achieving <$0.001 fees.

Users have wallets on dozens of chains. AA's promise of a unified identity fails if each chain requires separate smart account deployment and recovery setup.

• Key Benefit: Cross-chain smart account factories (using CCIP Read or LayerZero) enable single deployment on Ethereum, with lightweight counterfactual addresses on all chains.
• Key Benefit: Universal recovery modules that work across any EVM chain, secured by a single Ethereum L1 social graph.

Today's AA bundles are sequential. The next leap is parallel execution of UserOperations within a bundle, treating the bundle as a mini-block for an application.

• Key Benefit: Enables real-time, Subsecond-finality gaming and DeFi interactions within a session.
• Key Benefit: Parallel conflict detection can be handled by specialized bundlers, increasing throughput to 10,000+ TPS per app session.
