Nexus Elements - View History

Install

• Install widget:
  • npx shadcn@latest add @nexus-elements/view-history
• Ensure NexusProvider is installed and initialized before rendering.

Required setup before rendering

• Ensure useNexus().nexusSDK is initialized.
• Ensure wallet is connected before expecting history data.

Initialize SDK (required once per app)

• On wallet connect, resolve an EIP-1193 provider and call useNexus().handleInit(provider).
• Wait for useNexus().nexusSDK before expecting history fetches.
• Re-run init after reconnect if wallet session resets.

Render widget

"use client";

import ViewHistory from "@/components/view-history/view-history";

export function HistoryPanel() {
  return <ViewHistory viewAsModal={false} className="w-full" />;
}

Live prop contract

• viewAsModal? (default true): modal trigger vs inline list.
• className?: styling for trigger in modal mode.

SDK flow details (under the hood)

• Fetching:
  • calls sdk.getMyIntents()
  • stores full history and paginates client-side (ITEMS_PER_PAGE = 10)
• Status derivation:
  • fulfilled -> Fulfilled
  • deposited -> Deposited
  • refunded -> Refunded
  • fallback -> Failed
• Refresh integration:
  • listens for nexus:intent-history:refresh
  • bridge/transfer hooks dispatch this event after successful completion

Error and loading behavior

• history === null renders loading state.
• fetch failure sets loadError and renders retry UI.
• retry button re-runs getMyIntents fetch.

E2E verification

• Open modal and confirm history fetch on open.
• Scroll to bottom and confirm incremental pagination loads.
• Complete a bridge/transfer flow and confirm history refreshes.
• Disconnect wallet and verify empty/error handling remains stable.

Common failure cases

• No history displayed despite transactions:
  • verify wallet connected to same account used for intents.
• Infinite spinner risk:
  • ensure fetch errors are surfaced and retry path is shown.
