The True Cost of a 'Create Wallet' Button

Forcing users to manage cryptographic entropy is a UX failure that costs the industry millions of users daily. The 12-24 word mnemonic is a single point of catastrophic failure for non-custodial wallets.

• ~90% user drop-off at seed phrase backup screen.
• $10B+ in assets permanently lost due to seed mismanagement.
• Solutions: Social Recovery (Safe), MPC (Privy, Web3Auth), and embedded custodians (Coinbase Wallet, Magic) shift the burden from user to protocol.

Requiring a native token for a first transaction is a paywall before the product. It's the equivalent of demanding a toll to enter a free museum.

• Zero-balance wallets are bricked, requiring off-ramps like centralized exchanges.
• ~$5-50 minimum economic commitment just to interact, pricing out experimentation.
• Solutions: Gas Sponsorship (Biconomy, Gelato), Account Abstraction (ERC-4337) with paymasters, and L2s with stablecoin fee payment abstract this cost away.

A new user's assets are stranded on the chain they were minted on. Bridging is a multi-step, high-trust ordeal that feels like a scam.

• 7+ minute wait times and security risks with canonical bridges.
• 15-30% of value can be lost to slippage and fees on small bridges.
• Solutions: Native L1<>L2 bridges (Optimism, Arbitrum), intents-based aggregation (Across, Socket), and layerzero's omnichain futures create the illusion of a single liquidity pool.

Free gas for users is a marketing cost, not a protocol primitive. Projects rely on centralized relayers or opaque meta-transaction services, creating vendor lock-in and hidden liabilities.

• Centralized Relayer Risk: A single point of failure for user onboarding.
• Opaque Subsidies: Costs are buried in token treasuries, not sustainable unit economics.
• Wallet Lock-in: Users are trapped in the sponsor's ecosystem.

EIP-4337's Paymaster turns gas sponsorship into a verifiable, competitive marketplace. Apps can sponsor transactions, users can pay in any token, and the logic is enforced on-chain.

• Decentralized Execution: No single relayer; any bundler can process the sponsored tx.
• Transparent Accounting: Sponsorship logic and costs are auditable on-chain.
• Market Rates: Competition between paymaster services drives down costs.

Bridging assets to a new chain for gas is a $10B+ UX failure. Users must pre-fund wallets with native tokens, facing slow bridges, high fees, and security risks just to get started.

• Friction Multiplier: Adds 2-3 steps before any app interaction.
• Liquidity Fragmentation: Capital is stranded across chains.
• Bridge Risk: Users are exposed to intermediary protocols like LayerZero, Across, or Wormhole.

Let the user express a goal ('swap ETH for USDC on Arbitrum'), not a series of steps. Solvers (like those in UniswapX or CowSwap) compete to fulfill the intent, sourcing liquidity and gas cross-chain in one atomic bundle.

• User Doesn't Hold Gas: Solver pays all cross-chain and execution fees.
• Optimal Routing: Solvers find the best path across DEXs and bridges.
• Cost Internalization: Fee is baked into the swap, invisible to the user.

Self-custody is a tax on user attention and protocol support. Lost keys mean lost users and permanent state bloat. Recovery solutions are either centralized (social login) or impose massive on-chain costs.

• Support Nightmare: ~20% of users lose access, generating endless support tickets.
• Centralized Trade-off: Social logins (e.g., Web3Auth) reintroduce custodial risk.
• On-Chain Cost: Smart account recovery can cost $50+ in gas per user.

Smart accounts (like Safe{Wallet} or Argent) with multi-sig logic allow for recoverable, non-custodial wallets. Guardians can be other devices, friends, or institutions, with recovery executed via a Paymaster to hide gas costs.

• Non-Custodial Security: No single entity controls keys.
• Gasless Recovery: Sponsored transactions make the process seamless.
• Flexible Policies: Set thresholds and delays for different actions.
