# Agent instructions

You are advising on UX and product design for **EIP-6963: Multi Injected Provider Discovery**.
This document is the authoritative designer guide from EIPs for Designers.

- Treat **MUST NOT** items as hard constraints unless the user explicitly overrides.
- Use the **Vocabulary** section for UI copy; do not use avoided terms.
- Cite the canonical source URL when giving recommendations.
- Use the official specification only for protocol implementation detail, not as primary UX guidance.

## UX Impact

Users with multiple wallet extensions see all installed wallets in a selection modal — no more random 'last wallet wins' behavior. Design implications: replace single 'Connect Wallet' button with wallet picker showing icons, names, and rdns identifiers; render wallet icons as 96x96px minimum using <img> tags (SVGs must not execute scripts); design empty states for when no wallets are detected. Design decisions: choose between showing all wallets immediately vs progressive disclosure, decide wallet list ordering (alphabetical, most-used, last-connected), consider whether to remember user's preferred wallet across sessions, handle edge cases where wallets may impersonate others via rdns. 🟢 Live on 37+ wallets (Critical priority for wallet connection UX). Important limitation: solves desktop wallet conflicts but does NOT apply to mobile — mobile connection remains a known pain point (Connection Failures, Medium severity).

## Summary

EIP-6963 solves the "wallet conflict" problem. When users have multiple wallets (MetaMask, Coinbase, Rainbow), they used to fight over window.ethereum. Now, each wallet announces itself, and users see a clean list to choose from. No more random wallet hijacking the connection.

## For Designers

- You can show every detected wallet in a picker instead of auto-connecting the last one loaded.
- You can display wallet icons and names so users know which extension they are approving.
- You can remember the last chosen wallet while still letting users switch on reconnect.

## Applicability

### When to Use

- Users may have more than one browser wallet installed.
- Connect flows need wallet icons, names, and explicit user choice.
- The product targets desktop browsers where extensions compete for injection.

### When to Avoid

- Mobile wallet connection uses deep links or WalletConnect only.
- The product binds to one wallet provider with no user choice.
- Wallet discovery is handled entirely outside your UI (embedded wallet only).

## Problems It Solves

### Multiple wallets fighting for window.ethereum

Impact: critical

Old way: Last wallet to load wins, user can't choose

New way: Each wallet announces itself, user picks

### Users forced to disable wallets to use another

Impact: high

Old way: Disable MetaMask extension to use Rabby

New way: All wallets coexist, choose at connection time

### No wallet branding in connection flow

Impact: medium

Old way: Generic "Connect Wallet" with no context

New way: See wallet icons, names, choose your preference

## MUST NOT (Anti-Patterns)

- **Ignoring EIP-6963 and only using window.ethereum** (high)
  - Why: User has no choice, random wallet selected
  - Instead: Listen for eip6963:announceProvider events

- **Auto-selecting first wallet found** (high)
  - Why: Removes user choice, may pick wrong wallet
  - Instead: Always let user explicitly choose

- **Not showing wallet icons/branding** (medium)
  - Why: Users can't identify their wallet in the list
  - Instead: Display wallet icon and name from rdns

## UX Patterns

### Wallet Selector Modal

List of all available wallets to connect

User flow:

- User clicks Connect
- App listens for EIP-6963 announcements
- Shows list of detected wallets
- User clicks preferred wallet
- Connection proceeds with that wallet

Mockup registry key: `concept/wallet` (React UI on the live standard page).

### Wallet Discovery Badges

Show which wallets are available before connect

User flow:

- Page loads, discovers wallets
- Shows wallet icons as preview
- User sees their wallet is supported
- Clicks connect with confidence

Mockup registry key: `concept/wallet-discovery` (React UI on the live standard page).

## Mental Model

### Page load

The dApp dispatches eip6963:requestProvider and listens for wallet announcements instead of assuming window.ethereum.

### Wallet announcement

Each extension responds with its name, icon, rdns, and EIP-1193 provider. Multiple wallets can coexist without overwriting each other.

### User choice

Your connect modal lists every detected wallet with branding. Never auto-connect the first provider found.

### Selected provider

Connection proceeds with the chosen provider only. Remember the last choice for reconnect but keep switch visible.

### Mobile fallback

When no injected wallets exist, route to WalletConnect or deep links without breaking the desktop picker pattern.

## UI Components

### WalletList

Scrollable list of available wallets
States: loading, discovered, empty
Props: wallets[], onSelect

### WalletOption

Single wallet row with icon, name, and status
States: idle, selected, connecting
Props: wallet, onClick

### WalletIcon

Wallet brand icon with fallback
States: loaded, fallback
Props: icon, name

## On Monad

### Wallet Discovery

Ethereum: Standard EIP-6963 discovery

Monad: Same mechanism, works identically

Design implication: No changes needed for Monad support

## Key Takeaways

- EIP-6963 = multiple wallet discovery
- Always show wallet selector, never auto-pick
- Display wallet icons and names clearly
- Fall back to WalletConnect for mobile
- Handle no-wallets-detected gracefully

## Technical Notes

EIP-6963 uses DOM events for discovery. dApps dispatch eip6963:requestProvider, wallets respond with eip6963:announceProvider containing provider info (icon, name, rdns) and the EIP-1193 provider. This allows multiple wallets to coexist without overwriting window.ethereum.
