Decision snapshot

Is this worth validating?

Build this if

You can secure reliable on-chain data APIs and want to serve collectors who repeatedly evaluate wallets.

Avoid this if

You cannot guarantee sub-10-second data retrieval or lack access to floor-price and rarity data sources.

Validate first

Ship the no-login wallet lookup with 50 addresses, measure return usage rate and watchlist sign-ups.

Problem and target customer

Why this exists

Customer problem

NFT collectors juggle multiple block explorers, marketplace dashboards, and spreadsheets to assess a wallet's portfolio. There is no single focused tool that combines holdings, floor value, rarity, realized PnL, and whale activity into one view.

Who pays

Active NFT collectors and traders who need to evaluate any public wallet's portfolio quickly before making buy, sell, or watchlist decisions.

Business model

Freemium with a free no-login lookup tier and a paid workspace subscription for watchlists, alerts, and export.

Editorial note

Collectors evaluating a wallet today bounce between block explorers, marketplace pages, and spreadsheets. This tool collapses that workflow into a single paste-and-view experience: floor value, rarity, realized PnL, and whale activity in one dashboard.

The MVP stays narrow by focusing on one primary chain, one lookup flow, and a 15-minute cache to control external API costs. A paid watchlist tier adds recurring alerts and export for collectors who track multiple wallets.

Product goal

Who it serves and what it must change

Target user
Active NFT collector who evaluates public wallets before buying, selling, or tracking
Problem
Portfolio assessment requires multiple tools and manual spreadsheet work with no unified view of holdings, floor value, rarity, PnL, and whale activity
Measurable outcome
User pastes a wallet address and sees a complete portfolio breakdown within 10 seconds

Relations
Belongs to WalletSnapshot
TransactionEvent

Wallet transaction used to compute realized PnL

Fields
tx_hash, type, timestamp, value_usd, counterparty_address
Relations
Belongs to WalletSnapshot

Business rules

  • Snapshots expire after 15 minutes; expired snapshots trigger a fresh fetch
  • Realized PnL is computed from buy and sell transaction events per collection
  • Whale activity alert triggers when a watched wallet transacts above a user-defined threshold
  • Anonymous users can perform unlimited lookups but cannot save watchlists

Architecture and data flow

Components, integrations, and controls

Lookup API

Accept wallet address, check cache, fetch on-chain data if expired, return snapshot

PnL Engine

Compute realized gains and losses from transaction events

LLM Summary Service

Generate natural-language portfolio summary from computed metrics

Watchlist Service

Manage saved wallets and whale alert subscriptions

Snapshot Cache

Store and expire wallet snapshots with 15-minute TTL

Integrations

  • On-chain data API for NFT holdings, token balances, and transaction events
  • Marketplace API for floor prices and rarity data
  • OpenAI API for portfolio summary generation
  • Email or push notification for whale alerts

Data flow

  1. User submits wallet address to Lookup API
  2. Lookup API checks Snapshot Cache for valid entry
  3. If expired, fetch fresh data from on-chain and marketplace APIs
  4. PnL Engine processes transaction events
  5. LLM Summary Service generates portfolio summary
  6. Dashboard receives combined payload and renders

Failure handling

  • On-chain API timeout returns last cached snapshot with stale indicator
  • Marketplace API failure hides floor price with unavailable badge
  • LLM API failure degrades gracefully to raw metrics without summary

Security

  • No private keys or wallet connections required—public address only
  • Rate limiting on anonymous lookups to prevent API abuse
  • Subscriber data encrypted at rest in Postgres

Rate limits

  • Anonymous lookups: 30 per hour per IP
  • Watchlist alerts: 1 per wallet per event
  • LLM summary: 1 per snapshot fetch

Deliverables and acceptance

Definition of done for the MVP

Deliverables

  • No-login wallet lookup page
  • Portfolio dashboard with collections, tokens, PnL, and whale feed
  • Watchlist with whale alert subscriptions
  • PnL CSV export
  • 15-minute snapshot caching

Acceptance criteria

  • Pasting a valid wallet address renders a complete dashboard within 10 seconds
  • Collection cards display floor price and rarity rank per NFT
  • Realized PnL matches manual calculation from transaction events for 5 test wallets
  • Watchlist alert fires when a watched wallet transacts above the user threshold
  • Expired snapshots refresh automatically on next lookup

Recommended stack

Enough technology for the first version

Frontend

Lovable

Rapid build of a data-dense dashboard with wallet input, collection cards, and PnL charts using indigo-on-white styling.

Backend API

Railway

Host the API that fetches on-chain data, computes PnL, stores snapshots, and serves watchlist endpoints.

Database

Railway Postgres

Durable storage for wallet snapshots, watchlist entries, collections, NFTs, tokens, and transaction events.

Automation glue

Make

Optional webhook orchestration to queue wallet address submissions and trigger snapshot refresh when TTL expires.

LLM

OpenAI API

Generates a concise natural-language portfolio summary from computed holdings and PnL data.

Why this is sufficient

Lovable handles the visual dashboard and input flow. Railway provides the API and Postgres for snapshot caching and watchlist persistence. Make is bounded glue for webhook-triggered refreshes. OpenAI produces the portfolio summary that augments the raw metrics.
