## UX Impact

NFTs carry multiple transferable privileges (discounts, access, votes) that can be shared or assigned separately from ownership. Design implications: show privilege list with individual expiry dates, add 'Share Privilege' action, display privilege holder vs token owner. Design decisions: how to visualize privilege spreading/cloning — referral tree view, privilege inheritance tracking, balance utility discovery with UI complexity.

## Summary

EIP-5496 lets a single NFT carry multiple distinct privileges. Instead of one NFT = one permission, you can track "VIP access," "backstage pass," "merch discount," and "meet & greet" all on the same token. Each privilege can be granted, revoked, or transferred independently. Perfect for event tickets, membership cards, and subscription bundles where users expect multiple perks from one token.

## For Designers

- You can design UI that delivers one NFT holds all privileges as separate attributes.
- You can design UI that delivers grant specific privilege to someone without transferring NFT.
- You can standard hasPrivilege(tokenId, privilegeId) check.

## Applicability

### When to Use

- Your product addresses: nFTs represent only single permissions.
- Your product must handle: can't grant temporary access without full transfer.
- The flow should deliver: one NFT holds all privileges as separate attributes.
- You are designing a multi-privilege nft card experience with visible states and recovery paths.

### When to Avoid

- Clear "delegated to X" indicator on each privilege.
- Pre-check expiry and warn before user tries to use.
- Prominent revoke button next to each delegation.
- Wrong-address or approval mistakes are not recoverable in your product context.

## Problems It Solves

### NFTs represent only single permissions

Impact: critical

Old way: Need separate NFTs for VIP access, parking, and merch discount

New way: One NFT holds all privileges as separate attributes

### Can't grant temporary access without full transfer

Impact: high

Old way: Lend entire NFT (and all privileges) or nothing

New way: Grant specific privilege to someone without transferring NFT

### No standard way to check multiple perks

Impact: high

Old way: Custom logic per project to track entitlements

New way: Standard hasPrivilege(tokenId, privilegeId) check

### Privileges can't expire independently

Impact: medium

Old way: Whole NFT valid or invalid, no per-perk expiry

New way: Each privilege has its own expiration timestamp

### Hard to revoke specific access without burning NFT

Impact: medium

Old way: Must issue new NFT with reduced privileges

New way: Revoke individual privilege, keep others intact

## Anti-Patterns

### Not showing which privileges are delegated vs owned

Severity: critical

Users confused about what they can actually use vs lend

Instead: Clear "delegated to X" indicator on each privilege

### Allowing privilege use after expiry without clear error

Severity: high

Frustrating when access fails at the gate

Instead: Pre-check expiry and warn before user tries to use

### No revocation UI for delegated privileges

Severity: high

Users can't retract access they granted

Instead: Prominent revoke button next to each delegation

### Bundling all privileges into one indistinguishable token

Severity: medium

Users can't see or manage individual perks

Instead: Itemized privilege list with individual management

### Not showing remaining uses for consumable privileges

Severity: medium

User doesn't know if they have uses left

Instead: Show "2/5 uses remaining" for limited privileges

## UI Components

### PrivilegeBadge

Visual indicator for a single privilege status
States: active, expiring-soon, expired, used, delegated
Props: privilegeId, name, expiresAt, isDelegated

### PrivilegeTimeline

Visual timeline of privilege validity
States: before, active, ended
Props: startDate, endDate, privilegeName

### DelegationCard

Shows delegation details with revoke option
States: active, expiring, revoked
Props: privilege, delegatee, expiresAt, onRevoke

### PrivilegeVerifier

Real-time privilege checking component
States: checking, verified, denied, expired
Props: tokenId, privilegeId, address

## On Monad

### Delegation Speed

Ethereum: Delegating a privilege may take 15+ seconds

Monad: Sub-second finality for instant delegation

Design implication: Sharing privilege can feel instant, like sharing a link

### Verification at Scale

Ethereum: Multiple privilege checks may be slow/expensive

Monad: Fast parallel verification for complex entitlements

Design implication: Can check many privileges at once for gates

### Revocation

Ethereum: Revoking delegation requires gas and wait

Monad: Instant revocation with fast finality

Design implication: Revoke button can show immediate effect

### Gas for Multi-Privilege

Ethereum: Managing many privileges can cost significant gas

Monad: Cheap operations make fine-grained privileges practical

Design implication: Can offer more granular privilege management

## Key Takeaways

- EIP-5496 = multiple independent privileges per NFT
- Always show delegation status (owned vs delegated vs received)
- Display expiry prominently, warn before expiry
- Provide clear revocation UI for delegated privileges
- On Monad: leverage fast finality for instant sharing/revoking

## UX Patterns

### Multi-Privilege NFT Card

Display all privileges on a single NFT

User flow:

- User views their NFT
- UI queries all privilege IDs for token
- Fetches status/expiry for each privilege
- Displays clear list with visual indicators
- Used/expired privileges shown differently

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

### Privilege Delegation

Grant specific privilege to another user

User flow:

- User selects NFT to share from
- Picks specific privilege to delegate
- Enters recipient address
- Sets duration/expiry for delegation
- Confirms transaction
- Recipient gains privilege access

Mockup registry key: `generic/vault-deposit` (React UI on the live standard page).

### Privilege Verification Gate

Check privilege at entry point

User flow:

- Gate displays required privilege
- User scans QR or connects wallet
- System checks hasPrivilege()
- Verifies not expired
- Shows if direct ownership or delegated
- Grants or denies access

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

### Privilege Management Dashboard

View and manage all delegations

User flow:

- User opens privilege manager
- Sees all outgoing delegations
- Can revoke any active delegation
- Sees received delegations from others
- Can create new delegations

Mockup registry key: `generic/token-transfer` (React UI on the live standard page).

## Technical Notes

EIP-5496 adds privilegeIds to ERC-721, where each NFT can have multiple privileges. Key functions: hasPrivilege(tokenId, privilegeId) checks access, setPrivilege(tokenId, privilegeId, address, expiresAt) grants access. Privileges can be delegated to addresses other than the NFT owner with optional expiration. The owner retains the right to revoke delegations.
