# Technology & Security #### Plasma Chain Performance The choice of the Plasma Chain is central to the platform's offering: * Sub-Second Finality: This is crucial for high-leverage trading, ensuring that the price you see is the price you get, with no delayed fills or slippage surprises. * Zero Gas Fees: The zero-gas infrastructure of Plasma Chain eliminates the cost and complexity of managing gas tokens, simplifying the entire trading process. PlasmaPerps achieves sub-second latency by **removing the blockchain from the hot path** and treating trades as **signed off-chain intents**. Users sign orders with their wallet and send them via WebSocket to a stateless gateway, which forwards them to a **co-located sequencer + in-memory matching engine cluster**. The sequencer is the single logical ordering service: it timestamps and sequences intents, runs risk checks, and updates an in-memory orderbook and account state (positions, margin, PnL). Because this entire loop runs in RAM with no EVM calls and no disk I/O on the critical path, it can respond with execution reports (fills, partials, updated account state) in a few hundred milliseconds, similar to a traditional CEX matching engine. On-chain contracts sit on the **settlement path**, not the execution path. The sequencer periodically batches executed trades and state transitions into **compact state commitments** (or rollup-style proofs) and submits them to Plasma Chain settlement contracts. These contracts hold custody of margin collateral, maintain canonical balances and positions, enforce margin and liquidation rules, and update vault/fee/insurance accounting. Because the chain only processes **aggregated batches** instead of per-click transactions, it can provide strong safety and non-custodial guarantees without constraining latency. The combination of (1) **off-chain, in-memory matching and risk**, plus (2) **on-chain batched settlement with contract-controlled custody**, is what allows PlasmaPerps to deliver CEX-like speed while remaining non-custodial. #### Security and Transparency PlasmaPerps operates with a commitment to Trust through verification, not promises. * Non-Custodial: Funds are secured by audited smart contracts, not by any third party. * Onchain Settlement: All transactions and settlements are verifiable on the blockchain. * Audits: Our smart contracts have been thoroughly audited by leading security firms in the DeFi space. * Data Pipeline: We utilize a Hybrid Oracle + RWA (Real World Asset) Data Pipeline. This multi-source mechanism aggregates data from various sources to ensure our prices are resilient against manipulation and highly accurate, especially for RWA markets like stocks and commodities. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
