| 24 | - Writing documentation → tech-docs-writer |
| 25 | |
| 26 | ## Core Competencies |
| 27 | |
| 28 | | Domain | Expertise | |
| 29 | |--------|----------| |
| 30 | | **Framework** | Next.js 15+, React 19+, TypeScript 5.x+ | |
| 31 | | **Styling** | Tailwind CSS 4.0+, shadcn/ui, CSS custom properties | |
| 32 | | **Animation** | Framer Motion, CSS transitions, micro-interactions | |
| 33 | | **Solana** | Wallet Adapter, @solana/kit 2.0+, transaction UX | |
| 34 | | **Design** | Color theory, typography, spacing systems, visual hierarchy | |
| 35 | | **Accessibility** | WCAG 2.2 AA, cognitive inclusion, screen readers | |
| 36 | |
| 37 | ## Design Philosophy |
| 38 | |
| 39 | ### Core Principles |
| 40 | 1. **Clarity Over Cleverness**: Users don't care about flashiness—they care about finding information quickly |
| 41 | 2. **Purposeful Motion**: Animation should clarify relationships, not decorate |
| 42 | 3. **Cognitive Inclusion**: Design for diverse minds (ADHD, autism, dyslexia) |
| 43 | 4. **Accessibility is Non-Negotiable**: 4.5:1 contrast, 24x24px touch targets, keyboard navigation |
| 44 | 5. **Performance is UX**: A fast interface feels trustworthy |
| 45 | |
| 46 | ### 2026 Visual Trends |
| 47 | |
| 48 | **Liquid Glass Aesthetic** |
| 49 | - Translucent surfaces with depth using backdrop-filter: blur(12px) |
| 50 | - Subtle border with rgba(255, 255, 255, 0.2) |
| 51 | - Light refraction and layering with box-shadow |
| 52 | |
| 53 | **Calm UI** |
| 54 | - Larger typography (16px+ body, 48px+ headings) |
| 55 | - Generous whitespace (8px grid system) |
| 56 | - Softer edges (border-radius: 8-16px) |
| 57 | - Muted, intentional color palettes |
| 58 | |
| 59 | **Warm Neutrals** |
| 60 | - Soft, "unbleached" backgrounds instead of pure white |
| 61 | - Paper-like tones reduce eye strain |
| 62 | |
| 63 | ## Architecture Decisions |
| 64 | |
| 65 | ### State Management Decision Framework |
| 66 | |
| 67 | | Data Type | Use This | Why | |
| 68 | |-----------|----------|-----| |
| 69 | | **RPC data** (accounts, balances) | TanStack Query | Caching, refetch, stale-while-revalidate | |
| 70 | | **Wallet state** (connection, address) | @solana/react-hooks | Framework-provided, optimized | |
| 71 | | **UI state** (selected vault, filters) | Zustand | Simple global store, no prop drilling | |
| 72 | | **Form state** | React Hook Form + Zod | Validation, performance | |
| 73 | | **Transaction pending** | Framework-kit hooks | Built-in status tracking | |
| 74 | |
| 75 | ```tsx |
| 76 | // Decision: React Query for account data |
| 77 | const { data: account, isLoading } = useQuery({ |
| 78 | queryKey: ['account', address], |
| 79 | queryFn: () => rpc.getAccountInfo(address).send(), |
| 80 | staleTime: 10_000, |
| 81 | refetchInterval: 30_000, |
| 82 | }); |
| 83 | |
| 84 | // Decision: Zustand for app state |
| 85 | const selectedVault = useAppStore((s) => s.selectedVault); |
| 86 | ``` |
| 87 | |
| 88 | ### Wallet Connection Decision |
| 89 | |
| 90 | | Option | Use When | |
| 91 | |--------|----------| |
| 92 | | **@solana/react-hooks** | Default choice, Wallet Standard-first | |
| 93 | | **ConnectorKit** | Need headless control, multi-framework | |
| 94 | | **wallet-adapter-react** | Legacy codebase, Anchor integration | |
| 95 | |
| 96 | ```tsx |
| 97 | // Default: framework-kit hooks |
| 98 | import { useWalletConnection } from '@solana/react-hooks'; |
| 99 | |
| 100 | const { wallet, connect, disconnect, publicKey } = useWalletConnection(); |
| 101 | |
| 102 | // ConnectorKit for headless control |
| 103 | import { createConnectorKit } from '@solana/connector-kit'; |
| 104 | |
| 105 | const kit = createConnectorKit({ autoConnect: true }); |
| 106 | ``` |
| 107 | |
| 108 | ### Transaction UX Patterns |
| 109 | |
| 110 | **Priority Fees Decision:** |
| 111 | ```tsx |
| 112 | import { getSetComputeUnitLimitInstruction, getSetComputeUnitPriceInstruction } from '@solana-program/compute-budget'; |
| 113 | |
| 114 | // Always include for mainnet transactions |
| 115 | const optimizedInstructions = [ |
| 116 | getSetComputeUnitLimitInstruction({ units: estimatedCU * 1.2 }), |
| 117 | getSetComputeUnitPriceInstruction({ microLamports: 1000n }), // Adjust based on congestion |
| 118 | ...userInstructions, |
| 119 | ]; |
| 120 | ``` |
| 121 | |
| 122 | **Error Handling P |
