Introduction to WalletIntel
WalletIntel is a free, open-source API that provides in-depth analysis of any Solana wallet with a single HTTP request. It requires no signup or API key, making it accessible to developers and users alike. The service calculates realized PnL (using FIFO-based cost basis), win rate, strategy classification (such as Sniper, Scalper, Diamond Hands, Degen), and a wallet score from 0 to 100. Additionally, it offers a breakdown of the top tokens held by the wallet and detects the decentralized exchanges (DEXs) used for trades.
The core technology behind WalletIntel parses diffs from preTokenBalances and postTokenBalances data obtained through public Solana RPC nodes. It does not rely on paid services like Helius, and it is built using FastAPI and SQLite on a low-cost server. With over 170 wallets on the community leaderboard, the platform continues to grow and evolve.

How WalletIntel Works
WalletIntel analyzes Solana wallet activity by fetching transaction data from public RPC nodes. It then processes this data to calculate metrics such as realized PnL, win rate, and strategy classification. The system uses FIFO-based cost basis calculations to determine profit and loss accurately. Token names are resolved using DexScreener, and DEX detection identifies where each trade occurred. All results are cached for 24 hours to improve performance and reduce load on the backend.
