Automated Market Making Platform

Bullish's proprietary Automated Market Making (AMM) platform enables institutional market makers to provide continuous two-sided liquidity on the order book through fully customizable AMM Instructions with programmatic API access. The platform efficiently converts liquidity into thousands of individual bids and offers, creating more reliable and predictable depth than traditional centralized or decentralized exchanges.

AMM Architecture & Order Book Integration

The Bullish AMM evolves and improves upon the constant product market maker model (xy=k), generating unique liquidity from customer assets allocated as AMM Instructions. The system instantaneously creates thousands of discrete bids and offers distributed across the order book, with full integration into the central limit order book allowing AMM-generated liquidity to interact seamlessly with traditional limit orders.

Hybrid Model Benefits: This approach combines the capital efficiency of automated market making with the transparency and price discovery of order book-based trading, providing more predictable liquidity depth across varying market conditions compared to traditional AMM pools where liquidity is expressed as bonding curve abstractions.

AMM Instructions for Market Makers

AMM Instructions enable market makers to seamlessly make markets on the Bullish Order Book by allocating assets within specified trading parameters without requiring continuous manual order management.

Spot AMM Instructions

Fully customizable parameters include:

Market Selection: Choose which trading pairs to provide liquidity for across all available spot markets.

Minimum Bid/Offer Spread: Set minimum spread between buy and sell orders to ensure profitability thresholds.

Dynamic Spread: Configure spread adjustments that respond to market volatility and trading activity.

Price Boundaries: Define upper and lower price boundaries for liquidity provision, concentrating liquidity in expected price ranges.

Asset Quantity: Specify quantity of assets to allocate to the AMM Instruction.

Derivatives AMM Instructions

For perpetual and dated futures markets, AMM Instructions operate on a margin basis:

Margin-Based Collateral: Supply sufficient margin rather than actual assets, with collateral not required to be in the same denomination as the underlying market, enabling more flexible capital allocation.

Position Limits: Define the longest long or short position willing to take, providing risk boundaries for automated market making.

Spread Configuration: Similar to spot AMM Instructions, supporting customizable minimum and dynamic spreads.

Flexible Risk Profiles: Supply more or less collateral to match preferred risk profile, similar to standard derivatives trading on Bullish.

Revenue Generation

As market participants trade against AMM-generated bids and offers, the customer who initiated the AMM Instruction receives AMM payments through trading fees, spreads, and dynamic price adjustments, creating passive income opportunities while contributing to overall platform liquidity.

Programmatic API Access

Institutional market makers can place and manage AMM Instructions programmatically via comprehensive API suite:

REST API: Full-featured RESTful API for account management, AMM Instruction placement and modification, position monitoring, and historical data retrieval. Returns JSON responses compatible with virtually any programming language.

FIX Protocol: Financial Information eXchange (FIX) protocol support for institutional trading desks requiring standard industry connectivity, enabling integration with institutional order management systems (OMS) and execution management systems (EMS).

WebSocket API: Real-time market data and private account data streaming for monitoring order book updates, trade executions, price changes, and account positions without polling. Provides low-latency, bidirectional communication.

Market Data Access: Public market data includes order book depth, recent trades, ticker information, candle/OHLCV data, and 24-hour statistics. Private authenticated streams provide real-time updates on order fills, position changes, and margin requirements.

API Performance & Security

The API infrastructure is designed for high availability and low latency with rate limits calibrated for institutional trading volumes. Comprehensive error handling, request idempotency, and retry logic ensure reliable execution. API access requires secure authentication using API keys with configurable permissions, IP whitelisting support, and comprehensive documentation at api.exchange.bullish.com.

Compliance & Eligibility

AMM Instructions and derivatives AMM Instructions are classified as high-risk and only available to eligible institutional and corporate professional investors in select locations, subject to regulatory compliance requirements.

Target Clients: Institutional market makers, proprietary trading firms, algorithmic traders, and liquidity providers requiring automated market making capabilities with customizable parameters, risk controls, programmatic API access (REST, FIX, WebSocket), and passive income generation through providing liquidity to digital asset markets.
