Documentation for Injective’s on-chain orderbook exchange, covering spot markets, perpetual futures, expiry futures, and order types.

This section provides comprehensive documentation for traders and developers building on Injective’s exchange infrastructure. Whether you’re executing trades via API, integrating orderbook functionality into your dApp, or learning about margin requirements and derivatives, you’ll find detailed specifications for order types, fee structures, and trading instruments.

Injective redefines decentralized trading by combining the efficiency of centralized exchanges with the transparency and security of blockchain. Through Frequent Batch Auctions (FBA), Injective eliminates miner extractable value (MEV) and front-running by aggregating orders into discrete batches that execute at a single clearing price. Unlike traditional DEXs that rely on liquidity pools with constant product formulas, Injective’s on-chain CLOB enables precise limit orders, advanced order types, and institutional-grade execution. The innovative negative maker fee model—where liquidity providers earn rebates instead of paying fees—creates powerful incentives for market makers, resulting in tighter spreads and deeper liquidity than typical decentralized exchanges.

Key Concepts

Term	Definition
Central Limit Orderbook (CLOB)	A fully on-chain order matching system that enables transparent price discovery and shared liquidity across all Injective dApps, unlike AMM-based DEXs.
Frequent Batch Auctions (FBA)	Injective’s order execution mechanism that aggregates orders over discrete time intervals and clears them at a uniform price, eliminating MEV and front-running.
Negative Maker Fees	A fee structure where liquidity providers (makers) receive rebates instead of paying fees—currently -0.01% on eligible pairs—incentivizing deep orderbook liquidity.
Perpetual Futures	Derivative contracts without expiry dates that track the price of an underlying asset, typically using funding rates to align the contract price with spot markets.
Initial/Maintenance Margin	The collateral required to open (initial) and keep open (maintenance) a leveraged position; falling below maintenance triggers liquidation to protect the protocol.
