--- description: Track crypto wallets across multiple chains with real-time balance and transaction monitoring shortcut: tw --- # Track Wallet Portfolio Monitor cryptocurrency wallets across multiple blockchain networks with comprehensive portfolio analytics, DeFi position tracking, NFT holdings, transaction history, profit/loss analysis, and tax reporting integration. This command provides institutional-grade portfolio tracking capabilities for individual investors, traders, and portfolio managers. ## Overview The Wallet Portfolio Tracker provides real-time visibility into cryptocurrency holdings across Ethereum, Bitcoin, Binance Smart Chain, Solana, Polygon, and other major blockchain networks. It aggregates token balances, NFT collections, DeFi positions (staking, lending, liquidity pools), and transaction history into a unified portfolio view with automated valuation using real-time price feeds from CoinGecko and other market data providers. ## Key Features ### Multi-Chain Wallet Tracking - **Ethereum (ETH)**: Native ETH, ERC-20 tokens, ERC-721/1155 NFTs - **Bitcoin (BTC)**: Native BTC, ordinals, inscriptions - **Binance Smart Chain (BSC)**: BNB, BEP-20 tokens - **Solana (SOL)**: SOL, SPL tokens, Metaplex NFTs - **Polygon (MATIC)**: Native MATIC, ERC-20 compatible tokens - **Arbitrum, Optimism, Avalanche**: Layer 2 and alt-chain support - **Cross-chain aggregation**: Unified view across all networks ### Portfolio Value Calculation - **Real-time pricing**: CoinGecko API integration for 10,000+ tokens - **Historical price data**: Track portfolio value over time - **Multiple fiat currencies**: USD, EUR, GBP, JPY support - **Custom price feeds**: Override with DEX prices or manual values - **Gas cost tracking**: Track total fees paid across chains - **Unrealized gains/losses**: Current position P&L calculation ### NFT Holdings Tracking - **Collection valuation**: Floor price, rarity scores, estimated value - **Marketplace integration**: OpenSea, Rarible, Magic Eden data - **NFT metadata**: Images, attributes, ownership history - **Portfolio percentage**: NFT allocation vs fungible tokens - **Collections categorization**: Art, gaming, metaverse, PFPs ### DeFi Position Tracking - **Lending protocols**: Aave, Compound, Maker - supplied and borrowed assets - **Staking positions**: ETH 2.0, validator rewards, liquid staking - **Liquidity pools**: Uniswap, Curve, Balancer LP token valuation - **Yield farming**: Convex, Yearn, Beefy vault positions - **Derivatives**: Options, perpetuals, structured products - **Impermanent loss**: Real-time IL calculation for LP positions ### Transaction History Analysis - **Full transaction history**: All chains, all transaction types - **Categorization**: Transfers, swaps, DeFi interactions, NFT trades - **Counterparty analysis**: Identify exchanges, contracts, known entities - **Profit/loss per transaction**: Realized gains tracking - **Gas cost analysis**: Total fees, optimization opportunities - **CSV/Excel export**: Full transaction history for analysis ### Address Labeling System - **Exchange addresses**: Binance, Coinbase, Kraken auto-detection - **Personal wallet labels**: Custom names for your addresses - **Smart contract identification**: Protocol names, contract types - **Address book**: Save frequently interacted addresses - **Privacy mode**: Hide sensitive address labels in exports ### Historical Performance Charts - **Portfolio value over time**: Daily, weekly, monthly aggregation - **Asset allocation changes**: Track diversification over time - **Chain distribution trends**: See where your assets are moving - **Benchmark comparison**: Compare vs BTC, ETH, S&P 500 - **Drawdown analysis**: Maximum portfolio decline tracking - **ROI calculation**: Time-weighted returns, IRR ### Tax Reporting Integration - **FIFO/LIFO/HIFO**: Multiple cost basis calculation methods - **Capital gains reports**: Short-term and long-term gains - **Income tracking**: Staking rewards, airdrops, interest earned - **8949 form preparation**: IRS tax form compatible output - **CoinTracker integration**: Export to popular tax software - **Multi-jurisdiction**: Support for US, UK, EU tax rules ## Command Syntax ```bash /track-wallet [address] [options] ``` ### Arguments - `address` (required): Wallet address or ENS name to track - `--chains`: Comma-separated list of chains (default: all) - `--include-nfts`: Include NFT valuations (default: true) - `--include-defi`: Include DeFi positions (default: true) - `--fiat`: Fiat currency for valuation (default: USD) - `--historical-days`: Days of historical data (default: 30) - `--export`: Export format (csv, excel, json) - `--tax-year`: Generate tax report for specific year - `--label`: Save address with custom label ## Usage Examples ### Basic Portfolio Tracking ```bash /track-wallet 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb1 Portfolio Summary for 0x742d...bEb1 =============================================== Total Value: $125,432.18 USD Last Updated: 2025-10-11 14:32:18 UTC Chain Distribution: - Ethereum: $89,234.50 (71.1%) - Polygon: $21,432.18 (17.1%) - BSC: $10,234.90 (8.2%) - Arbitrum: $4,530.60 (3.6%) Top Holdings: 1.

**API rate limits**: Implements caching to minimize API calls (5-minute cache) - **Concurrent scanning**: Uses asyncio for parallel chain scanning - **Database persistence**: SQLite for historical tracking without external dependencies - **Batch processing**: Fetches multiple token balances in parallel - **Error handling**: Graceful degradation if individual chains fail ## Tax Reporting Features The tracker automatically categorizes transactions for tax purposes: - **Capital gains**: Buy/sell events with cost basis tracking - **Income**: Staking rewards, LP fees, airdrops - **Expenses**: Gas fees deductible as transaction costs - **IRS Form 8949**: Pre-formatted output for tax filing - **Multiple jurisdictions**: US (FIFO/LIFO), UK, EU compliance ## Security Best Practices - **Read-only access**: Never requires private keys - **API key protection**: Store in environment variables, never commit - **Rate limiting**: Respects API provider limits - **Data privacy**: Local database storage, no cloud sync - **Address validation**: Checksums prevent typos - **Export encryption**: Optional password protection for CSV exports ## Future Enhancements - Bitcoin UTXO tracking with Blockchain.info API - Solana SPL token support with Solana Web3.js - NFT floor price tracking via OpenSea/Rarible APIs - DeFi protocol integrations (Aave, Compound, Uniswap full support) - Real-time WebSocket updates for live tracking - Mobile app export (JSON format for companion apps) - Tax software integrations (CoinTracker, Koinly, CryptoTaxCalculator) This comprehensive wallet portfolio tracker provides institutional-grade analysis capabilities for crypto investors and traders across multiple blockchain networks.
