Platform Architecture

PNL Games is engineered for real-time performance, competitive integrity, and smooth scalability — all built natively on Solana.

Real-Time Wallet Tracking

PNL Games uses Helius RPC Geyser WebSocket subscriptions to listen for on-chain activity from individual player wallets. This allows the platform to monitor trades, wallet balances, and token interactions with minimal latency, ensuring a real-time competitive experience.

• Every registered game wallet is subscribed individually

• Updates to leaderboard data are streamed live as trades happen

• All trades are verified against our token filter and rules engine

Token Filtering: Pump AMMs Only

To maintain fair and consistent gameplay, PNL Games only tracks tokens launched via pump.fun. This ensures that all participants are trading from the same ecosystem under the same conditions — no random tokens, no off-meta pairs, no exploits.

We only track pump fun program ids, so only coins minted on the pump platform are tracked. These are the exact ones we track:

const PROGRAM_IDS = { // Essential PumpFun programs for token creation and minting PUMP_FUN_TOKEN_MINT_AUTH: 'TSLvdd1pWpHVjahSpsvCXUbgwsL3JAcvokwaKt1eokM',

// Current PumpFun AMM system PUMP_FUN_ROUTER: 'BSfD6SHZigAfDWSjzD5Q41jw8LmKwtmjskPH9XW1mrRW', PUMP_FUN_AMM_IMPL: 'pAMMBay6oceH9fJKBRHGP5D4bD4sWpmSwMn52FMfXEA',

// Helper service used by PumpFun for API integration BLOXROUTE_API: 'HQ2UUt18uJqKaQFJhgV9zaTdQxUZjNrsKFgoEDquBkcx',

// Pump.fun bonding curve program ID PUMP_FUN_BONDING_CURVE: '6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P',

// Raydium AMM program ID RAYDIUM_AMM: '675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8' };
