What is Lighter DEX?
Lighter is a decentralized crypto perps trading platform built on a high-performance Ethereum layer-2 network. Lighter is permissionless while allowing traders to maintain custody of their assets while trading on the platform.
It leverages blockchain and smart contract technology to create a perps trading platform that offers CEX-level efficiency with blockchain-level security, decentralization, and privacy. Lighter DEX currently supports over 95 crypto assets and forex pairs with up to 50X leverage.
How Lighter DEX Works?
Lighter Protocol’s main goal is to create a user-friendly Perps trading platform where users maintain custody of their assets at any point of the trade. To achieve this, it employs several technologies and sub-protocols to handle regular trading, risk management, and remittances. The core of Lighter Protocol consists of;
Off-chain Orderbook
Lighter operates an off-chain orderbook that handles trade requests. The orderbook holds records of trade requests and executes them in a ‘time and price priority.
Lighter Core
Lighter Core is the trading engine of the Lighter Protocol. It handles onchain validation for orders matched off-chain. Lighter core user zero-knowledge roll-up and validation technology to sequestrate orders for confirmation on the Ethereum network.
Lighter Core ensures that the protocol maintains smooth operation while offering blockchain-level security and transactional privacy through ZK validations.
Orders executed off-chain are batched by the Lighter Sequencer and validated using Zk-SNARKs to generate a succinct proof of data validity.
Smart Contracts
Smart Contracts are used to maintain defined states for the rollup and enforce protocol operations. It keeps Lighter Core in check by ensuring correct ordering for transactions and a record of users’ assets at each new state of the rollup root. Lighter protocol provides an exit route for the protocol if the sequencer fails temporarily.
The exit route is known as the Exit Hatch mode. Here, the smart contract is halted, and users are allowed to withdraw their assets directly on the Ethereum network.
LIT Token
LIT is the native token of the Lighter DEX. It is an ERC-20 standard token on the Ethereum network, serving specific utilities on the Lighter Protocol.
- LIT holders are part of the Lighter DAO and contribute to the project’s governance through community votes on improvement proposals.
- It is also used to promote the protocol’s adoption through incentivized promotional programs like liquidity farming.
- LIT holders will also benefit from future staking programs that support the token.
Who is Lighter DEX Best Suited for?
Lighter is suited for crypto perpetual traders. Anyone conversant with perps trading can use the platform due to the similarity with CEX trading interfaces. However, Lighter is best suited for perp traders who understand basic DeFi operations and self-custody enthusiasts in search of secure and private trading platforms.
Due to the advanced design and blockchain complexity, non-perp traders and newbies with insufficient knowledge of DeFi transactions may struggle with first-time usage.
Is Lighter DEX Safe and Legitimate?
Yes, Lighter is a legitimate crypto perp DEX. The platform has received industry-wide support, is integrated with other reputable DeFi protocols, and formed partnerships with other trusted projects. The protocol is built on the blockchain and, as such, inherits blockchain-level security.
However, due to the complexity, Lighter DEX may be exposed to smart contract vulnerabilities. Therefore, we recommend that you apply risk management precautions while using the platform. Fund your trading accounts with only the amount you wish to trade with in the short term. Ensure the disconnect and revoke approvals after each trading session.
Factors to Consider Before Using Lighter DEX
Here are a few factors to consider before using Lighter DEX
1. Liquidity
Liquidity on Lighter DEX is good, especially for top assets. You will be able to complete small to mid-level volume trades with little or no slippage. However, if you are trading large volumes and using high leverage, we recommend that you assess the available liquidity. Liquidity on Lighter is considerably lower than that of top CEX perps trading platforms.
2. Leverage Levels
Lighter’s 50x maximum leverage works for most traders but may be insufficient for risk-savvy traders. If you are a risk-savvy trader, consider perps trading platform that offers sufficient leverage.
3. Supported Assets
Lighter is consistently expanding its asset support through regular listings. The platform currently supports only about 100 contracts, including exotic forex pairs. This is comparatively a low coverage of the crypto market. As such, the asset you wish to trade may not be supported on Lighter at this time. Check supported assets before funding your account.
