## UX Impact

Users hold traditional financial bonds on-chain with familiar terms — ISIN, coupon rate, maturity date, denomination, principal. Design implications: use familiar bond terminology (coupon, maturity, ISIN), display denomination-based minimum amounts, show coupon payment schedules, enable principal/interest tracking, support callable/puttable/convertible bond variants. Design decisions: whether to show yields in basis points or percentages, how to display accrued interest, representing cross-chain bond operations for multi-chain deployments.

## Summary

Users hold traditional financial bonds on-chain with familiar terms — ISIN, coupon rate, maturity date, denomination, principal.

## For Designers

- You can label fields ISIN, Coupon, Maturity, Denomination on bond detail using traditional finance layout.
- Your portfolio can show accrued interest and next coupon date per holding.
- You can badge Callable or Puttable variants with explainer tooltips.

## Applicability

### When to Use

- Product lists tokenized bonds or structured debt.
- Investors expect capital-markets terminology.
- ERC-7092 contracts power holdings.

### When to Avoid

- Generic yield tokens without bond structure.
- Retail users with no bond literacy and no education layer.
- Contract lacks ISIN and schedule fields.

## Problems It Solves

### Crypto UI on traditional securities

Impact: high

Old way: APY and token amount only

New way: ISIN, coupon, maturity bond card

### Wrong lot size submissions

Impact: high

Old way: Revert at settlement

New way: Denomination gate before sign

### Missed callable events

Impact: medium

Old way: Surprise early redemption

New way: Callable badge and notice period UI

## MUST NOT (Anti-Patterns)

- **Showing bond as generic yield farm** (critical)
  - Why: Mispriced risk and tax treatment
  - Instead: Bond term sheet with ISIN and maturity

- **Fractional buy below denomination** (high)
  - Why: Revert after user signs
  - Instead: Lot stepper locked to denomination multiples

- **Hiding callable/puttable flags** (high)
  - Why: Investors miss early redemption risk
  - Instead: Variant badges on card and confirm

## Design Decisions

### Yield as APY or coupon?

Recommendation: Coupon rate % plus payment frequency for bonds.

Rationale: DeFi APY mental model misprices fixed income.

### Basis points or percent?

Recommendation: Percent for retail; bps toggle for institutional.

Rationale: Dual audience common in tokenized RWAs.

### Accrued interest on screen?

Recommendation: Yes on detail; optional on portfolio row.

Rationale: Accrual affects purchase price in secondary.

## States to Design

### Active holding

Trigger: User owns bond before maturity.

User need: Track income and maturity.

Design response: Coupon schedule and accrued interest on card.

### Below minimum purchase

Trigger: User enters invalid lot.

User need: Fix before submit.

Design response: Minimum denomination is X inline error.

### Coupon payment due

Trigger: Payment date approaching.

User need: Expect cash flow.

Design response: Next coupon in N days notification.

### Matured

Trigger: Past maturity date.

User need: See principal returned.

Design response: Matured badge with redemption summary.

### Called by issuer

Trigger: Callable bond redeemed early.

User need: Understand early exit.

Design response: Called notice with proceeds breakdown.

## Vocabulary

- Use "Coupon rate" instead of "Yield APY": Fixed income correct term.

- Use "Maturity date" instead of "Expiry timestamp": Finance language.

- Use "Minimum investment" instead of "Denomination unit": Retail investor term.

## UX Patterns

### Bond Term Sheet Card

Traditional finance layout for on-chain bond.

Components: ISINRow, CouponRate, MaturityDate, VariantBadge

User flow:

- Open bond
- Read terms
- Check schedule
- Purchase valid lot

Mockup registry key: `erc-4337/bundled-defi` (React UI on the live standard page).

### Coupon Schedule View

Payment dates and accrued interest.

Components: ScheduleTable, AccruedInterest, NextCouponHighlight

User flow:

- View holding
- Open schedule
- See next payment
- Track history

Mockup registry key: `erc-4337/bundled-defi` (React UI on the live standard page).

## What to Prototype First

### Bond detail card

Investors diligence terms before buy.

Covers: Plain bond, Callable, Convertible

- ISIN row
- Coupon rate
- Maturity date
- Denomination minimum

### Coupon schedule

Income investors track payment dates.

Covers: Upcoming coupon, Paid history

- Schedule table
- Next payment highlight
- Accrued interest

### Purchase denomination gate

Bonds trade in minimum chunks.

Covers: Below minimum, Valid lot

- Minimum denomination callout
- Lot size stepper
- Total cost preview

### Callable notice

Issuer may redeem early — surprise if hidden.

Covers: Callable date approaching, Called

- Callable badge
- Notice period
- Redemption amount

## Mental Model

### ISIN

Standard security identifier — trust and reconciliation anchor.

### Coupon

Periodic interest payment — show rate and schedule.

### Maturity

Principal return date — countdown matters.

### Denomination

Minimum trade size — not fractional like typical tokens.

### Variant flags

Callable, puttable, convertible change risk — badge each.

## Seen in the Wild

- Backed Finance: Bond and equity token terminology patterns. (https://backed.fi/)

- Bloomberg: Reference layout for ISIN and coupon presentation. (https://www.bloomberg.com/)

## On Monad

### Bond settlement

Ethereum: Coupon claim txs costly

Monad: Lower fees for frequent coupon claims

Design implication: One-tap claim coupon on Monad.

### Institutional dashboards

Ethereum: Multi-bond refresh slow

Monad: Fast reads for portfolio bond grids

Design implication: Live accrued interest updates on Monad.

## Technical Notes

ERC-7092 bonds use capital-markets fields; never present as DeFi yield without term disclosure.
