## UX Impact

Users can redeem the same NFT for multiple different perks across different campaigns — a concert ticket NFT might be redeemable for entry, merchandise, and a meet-and-greet separately. Design implications: show list of available redemptions per NFT with status (available/redeemed/shipping), display operator-specific redemption flows, design redemption history view, show which campaigns/operators have active redemptions. Design decisions: how to organize multiple redemptions visually, whether to show redemption status progression (redeemed → paid → shipping), handling operator-specific metadata display, UX for discovering new redemption opportunities.

## Summary

Users can redeem the same NFT for multiple different perks across different campaigns — a concert ticket NFT might be redeemable for entry, merchandise, and a meet-and-greet separately.

## For Designers

- You can list Available redemptions as cards with operator name and status per perk.
- Your history view can group by campaign with Redeemed → Shipped progression.
- You can notify when new redemption opportunities attach to owned tokens.

## Applicability

### When to Use

- Event or membership NFTs unlock multiple perks over time.
- Different operators run separate redemption campaigns.
- ERC-6672 tracks per-redemption state.

### When to Avoid

- Single redeem-then-burn only.
- One operator one perk.
- Off-chain redemption only with no on-chain status.

## Problems It Solves

### One redeem burns all perks

Impact: high

Old way: Single consume destroys other rights

New way: Independent redemption slots per perk

### Confusion which vendor fulfills what

Impact: medium

Old way: Single support email

New way: Operator label on each redemption card

### Lost track of claimed perks

Impact: medium

Old way: No history

New way: Redemption timeline per NFT

## MUST NOT (Anti-Patterns)

- **Single Redeem button for all perks** (critical)
  - Why: Claims wrong perk or all at once
  - Instead: Separate CTA per perk card

- **No operator label** (high)
  - Why: Support chaos
  - Instead: Operator name on every perk row

- **Hiding fulfilled perks** (medium)
  - Why: User cannot prove attendance
  - Instead: History tab with fulfilled state

## Design Decisions

### Organize by operator or perk type?

Recommendation: Group by operator with perk subtitles.

Rationale: Support routes to operator.

### Show shipping progression?

Recommendation: Yes for physical; instant for digital.

Rationale: Different expectations per perk type.

### Discovery of new redemptions?

Recommendation: Push plus in-app New on token card.

Rationale: Post-mint campaigns add value.

## States to Design

### Perk available

Trigger: Not yet redeemed.

User need: Claim clearly.

Design response: Green Available with Redeem CTA.

### Redeemed — processing

Trigger: On-chain redeem done; fulfillment pending.

User need: Track fulfillment.

Design response: Redeemed — preparing shipment.

### Shipped / fulfilled

Trigger: Operator completed.

User need: See done.

Design response: Fulfilled checkmark; no CTA.

### New perk added

Trigger: Campaign update.

User need: Discover new value.

Design response: New badge and notification.

### All perks exhausted

Trigger: Every slot used.

User need: See memento value.

Design response: All rewards claimed summary.

## Vocabulary

- Use "Available reward" instead of "Redemption slot 2": Perk language.

- Use "Claimed" instead of "Redemption executed": User past tense.

- Use "Fulfilled by [operator]" instead of "Operator callback complete": Plain fulfillment copy.

## UX Patterns

### Multi-Redemption List

Per-perk cards with status and operator.

Components: PerkCard, StatusPill, OperatorLabel

User flow:

- Open NFT
- See perks
- Redeem one
- Status updates independently

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

### Redemption History

Timeline of claims across campaigns.

Components: HistoryTimeline, StatusProgress

User flow:

- Open history
- See past redeems
- Track shipping

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

## What to Prototype First

### Multi-redemption dashboard

Holder sees all perks at once.

Covers: 3 available, Mixed status, All redeemed

- Perk cards
- Status pills
- Operator label
- Redeem CTA each

### Single perk redeem flow

Each operator flow may differ.

Covers: Digital perk, Physical ship

- Operator branding
- Form fields
- Confirm redeem

### Redemption history timeline

Audit past claims across campaigns.

Covers: History list

- Date
- Perk name
- Status progression

### New perk discovery

Campaigns add redemptions post-mint.

Covers: New badge on perk

- New redemption available toast
- Highlight in list

## Mental Model

### One NFT

Single token holds multiple redemption rights.

### Redemption slot

Independent perk with own status.

### Operator

Party fulfilling specific redemption.

### Status progression

Available → Redeemed → Shipped per perk.

### Exhaustion

Each perk redeem once unless multi-use defined.

- Courtyard: Physical redemption status tracking. (https://courtyard.io/)

- Ticketmaster NFT: Event perk redemption patterns. (https://www.ticketmaster.com/)

## On Monad

### Multiple redeem txs

Ethereum: Gas discourages claiming all perks

Monad: Low fees enable claiming every perk

Design implication: Batch redeem optional on Monad.

### Status updates

Ethereum: Shipping status lag

Monad: Fast on-chain redeem confirmation

Design implication: Instant Redeemed state after claim on Monad.

## Technical Notes

ERC-6672 tracks independent redemption states; never use one button for all perks.
