Lighter is an orderbook-based perpetual DEX (zkLighter) — meaning you trade against a live orderbook with verifiable matching and liquidations, more like a CEX experience than a typical AMM-style perp DEX. It runs on Base (and Monad).

Here's how to trade on it, step by step:

1. Open the app — Lighter is web-based, no download needed.

2. Connect your wallet — connect an EVM wallet (MetaMask, Rabby, etc.) and switch to Base if it isn't auto-detected. You'll need ETH on Base for gas.

3. Deposit collateral — deposit USDC (or another supported collateral) into the protocol's smart contract. This becomes your margin. You can also use isolated or cross margin depending on what the interface offers per market.

4. Pick a market — choose the perp pair you want (e.g. BTC, ETH, or whatever's listed). Since it's orderbook-based, you get real bid/ask prices rather than a single AMM price.

5. Place an order — two main order types:

• Market order — fill immediately at the best available price.
• Limit order — set your own price and wait for a match.

6. Set leverage & margin — choose your leverage and how much collateral to allocate to the position. Higher leverage = higher liquidation risk, so size accordingly.

7. Manage the position — close by selling (if long) or buying (if short), set take-profit/stop-loss if available, and watch your liquidation price. Because Lighter verifies matching and liquidations on-chain, price data and liquidation mechanics are intended to be transparent rather than oracle-driven.

A couple of things to know:

• This is a decentralized perp DEX — you self-custody your collateral (minus what's posted as margin) rather than trusting an exchange's custody.
• As an orderbook DEX it may have different liquidity depth than the largest centralized venues, so wide markets may have thinner books — check the orderbook before placing large market orders.
• This is not financial advice — leveraged perpetuals carry high risk of losing your entire margin.
