How to track Lighter positions and PnL

Tracking a Lighter account follows the same happy rule as every on-chain perp venue: the account is an address, and the address is public. Positions, orders, fills and funding are readable without API keys or permissions. What deserves your attention is the same trio as everywhere in perps: exposure, liquidation distance, and the funding meter running under every open position.

What Lighter is, in one paragraph

Lighter is a perpetuals exchange built as a rollup with a real order book, aiming at the same promise as its peers: exchange-grade trading where the venue cannot quietly cheat, because state is verifiable on-chain. For a tracker, the architecture detail that matters is simpler: accounts and their positions are public data tied to your wallet address.

The numbers worth watching

• Open positions with entry, mark and liquidation price; distance to liquidation is the number that pages you at night.
• Margin mode and free collateral, which decide whether one bad trade stays one bad trade.
• Funding paid and received per position; over a held week it quietly rewrites the PnL.
• Realized PnL from closed fills, the only number that survives into your tax file.

The cross-venue problem, again

Almost nobody trades Lighter alone. There is a Hyperliquid main, maybe dYdX or GMX legacy positions, and every venue draws its own dashboard with its own PnL definition. The question that matters at week’s end, total exposure and honest PnL across all of them, needs aggregation with one normalized definition.

Reading it in TrueHold

Paste your address and TrueHold reads Lighter alongside Hyperliquid, with your exchange futures joining through read-only keys: positions, funding and history normalized and totalled next to your spot, DeFi and NFTs. Read-only by construction, nothing connected, nothing signable, and one exposure number instead of four dashboards.
