# Agent instructions

You are advising on UX and product design for **EIP-658: Transaction Status Code in Receipts**.
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

Transaction receipts include explicit success (1) or failure (0) status — no more guessing from gas usage. Design implications: show clear green checkmark/red X for transaction outcomes, display revert reason when available, distinguish between 'transaction included but failed' vs. 'transaction not included'. Design decisions: how to present failed transactions (some users expect failed = not charged, need education); whether to auto-expand failure details or keep UI clean.

## Summary

EIP-658 added a simple status field to transaction receipts: 1 for success, 0 for failure. Before this, wallets had to use hacky methods to determine if a transaction actually worked. Now every wallet can show a clear checkmark or X after any transaction, making blockchain feel more like normal software.

## For Designers

- You can design UI that delivers receipt contains explicit status: 1 = success.
- You can clear "Transaction Failed" message with status in the interface.
- You can design UI that delivers simple boolean check: receipt.status === 1.

## Applicability

### When to Use

- Your product addresses: no reliable way to know if transaction succeeded.
- Your users saw "confirmed" but funds didn't move.
- The flow should deliver: receipt contains explicit status: 1 = success, 0 = failure.
- You are designing a transaction status indicator experience with visible states and recovery paths.

### When to Avoid

- Always check status field and show Success or Failed explicitly.
- Parse revert reason and show actionable suggestion.
- Clearly show "Gas charged: 0.01 ETH (transaction failed but gas was used)".
- Protocol plumbing is invisible and never surfaces in user-facing UI.

## Problems It Solves

### No reliable way to know if transaction succeeded

Impact: critical

Old way: Compare gas used to gas limit, hope remaining gas indicated success

New way: Receipt contains explicit status: 1 = success, 0 = failure

### Users saw "confirmed" but funds didn't move

Impact: critical

Old way: Transaction confirmed but reverted, user confused why nothing happened

New way: Clear "Transaction Failed" message with status

### Apps couldn't reliably track transaction outcomes

Impact: high

Old way: Complex heuristics to guess success, sometimes wrong

New way: Simple boolean check: receipt.status === 1

### Block explorers showed ambiguous results

Impact: high

Old way: "Transaction included in block" with unclear outcome

New way: Green checkmark for success, red X for failure

## MUST NOT (Anti-Patterns)

- **Showing "Confirmed" for failed transactions** (critical)
  - Why: Confirmation means included in block, not success. Users think it worked.
  - Instead: Always check status field and show Success or Failed explicitly

- **Not explaining why transaction failed** (high)
  - Why: User knows it failed but not what to do about it
  - Instead: Parse revert reason and show actionable suggestion

- **Hiding gas charges on failed transactions** (high)
  - Why: Users don't understand why they lost money on a failed tx
  - Instead: Clearly show "Gas charged: 0.01 ETH (transaction failed but gas was used)"

- **Using same color for pending and success** (medium)
  - Why: Users can't distinguish waiting from done
  - Instead: Distinct colors: yellow=pending, green=success, red=failed

## UX Patterns

### Transaction Status Indicator

Clear visual feedback for transaction outcome

User flow:

- User submits transaction
- Pending state shown while waiting
- Receipt received with status field
- Clear success/failure indicator displayed
- User knows exactly what happened

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

### Failed Transaction Explanation

Help users understand why transaction failed

User flow:

- Transaction reverts on-chain
- Receipt shows status = 0
- UI displays clear failure message
- Reason explained in plain language
- Retry option offered

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

### Transaction History with Status

Show success/failure status for all past transactions

User flow:

- User views transaction history
- Each transaction shows status icon
- Success = checkmark, Failed = X
- At-a-glance understanding of outcomes

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

## UI Components

### TransactionStatusBadge

Visual indicator of transaction success/failure
States: pending, success, failed
Props: status, showLabel, size

### ReceiptDisplay

Show full transaction receipt details
States: loading, success, failed
Props: receipt, showTechnical, onRetry

### FailureExplanation

Human-readable failure reason
States: generic, specific, actionable
Props: errorCode, errorMessage, suggestion

## On Monad

### Fast Status Updates

Ethereum: Wait 12+ seconds for receipt with status

Monad: Sub-second finality means instant status feedback

Design implication: Can skip elaborate "waiting" animations, show status almost immediately

### Error Recovery

Ethereum: Failed tx means wait and retry manually

Monad: Fast enough to auto-retry failed transactions

Design implication: Consider "Auto-retry on failure" option for common error types

### Status Display Duration

Ethereum: Show pending state for 15+ seconds

Monad: Pending state lasts <1 second

Design implication: Pending indicator may flash by too fast, ensure success state is prominent
