Ethereum dApp UX patterns and implementation guidance. Routes to domain-specific skills for token approvals, transaction signing, gas/fees, multi-chain, onboarding, wallet connection, safety, and shared cross-cutting patterns. Use this skill whenever building, reviewing, or designing ANY Ethereum dApp UI — it will point you to the right detailed skill for your task.
Token approval UX patterns for Ethereum dApps: exact-amount approvals, Permit2 gasless signatures, EIP-5792 batched approve+action, human-readable approval display, and in-app approval management/revocation. Use this skill whenever building or reviewing ANY ERC-20 token approval flow, permit signing, spending permission UI, allowance checking, or approval revocation feature — even if the user just mentions 'approve', 'allowance', 'permit', or 'spending permission'.
Gas and fee UX patterns for Ethereum dApps: paymaster sponsorship (ERC-7677), fiat fee display, ERC-20 gas payment, L1/L2 fee breakdowns, and high-gas warnings. Use this skill whenever building or reviewing ANY fee display, gas estimation, transaction cost UI, paymaster integration, or fee-related warning — even if the user just mentions 'gas', 'fees', 'transaction cost', 'paymaster', or 'sponsored transactions'.
Multi-chain UX patterns for Ethereum dApps: unified cross-chain balances, automatic network switching, chain-aware address validation (ERC-7930), intent-based cross-chain transfers (ERC-7683), and consistent smart account addresses via CREATE2. Use this skill whenever building or reviewing ANY multi-chain feature, cross-chain transfer, bridge UI, network switching flow, or aggregated balance view — even if the user just mentions 'multi-chain', 'cross-chain', 'bridge', 'network switch', or 'L2'.
Onboarding UX patterns for Ethereum dApps: delayed recovery phrase backup, jargon-free UI text, simple/advanced mode toggle, internationalization (i18n), and progressive disclosure. Use this skill whenever building or reviewing ANY first-run experience, new user flow, wallet creation UI, seed phrase backup, jargon replacement, i18n setup, or progressive disclosure pattern — even if the user just mentions 'onboarding', 'new users', 'first time', 'beginner friendly', or 'localization'.
Safety and security UX patterns for Ethereum dApps: risk-differentiated warnings (info/caution/danger tiers), ENS name resolution, ERC-55 address checksum validation, spam token filtering, and safe max-send calculations. Use this skill whenever building or reviewing ANY address input, warning system, risk indicator, token filtering, ENS display, send-max feature, or phishing protection — even if the user just mentions 'safety', 'security', 'warnings', 'address validation', 'ENS', 'spam tokens', or 'send max'.
Transaction signing UX patterns for Ethereum dApps: EIP-712 typed structured data, human-readable transaction summaries, transaction simulation/preview, multi-step signing progress, EIP-7702 batch signing, and Sign-In with Ethereum (SIWE/EIP-4361). Use this skill whenever building or reviewing ANY signature request, transaction confirmation UI, signing flow, SIWE implementation, transaction preview, or multi-step transaction progress — even if the user just mentions 'signing', 'signature', 'confirm transaction', 'SIWE', 'sign in with ethereum', or 'transaction preview'.
Wallet connection UX patterns for Ethereum dApps: EIP-6963 multi-wallet discovery, mobile deep linking, session persistence and auto-reconnect, embedded/smart wallets for new users, and WalletConnect v2 fallback. Use this skill whenever building or reviewing ANY wallet connection flow, connect button, wallet modal, session management, embedded wallet, WalletConnect integration, or mobile wallet linking — even if the user just mentions 'wallet', 'connect', 'disconnect', 'WalletConnect', 'embedded wallet', or 'wallet discovery'.
