BULK Exchange Market Making: The Alpha Program, Maker Rebates, and HFT Integration

BULK Exchange is designed to attract professional market makers. Zero maker fees during the Genesis Phase, maker rebates up to −2.0 bps at high volume tiers, the Alpha Program distributing 7.5% of taker fee revenue to qualifying market makers, and an open client SDK for algorithmic integration.

Why BULK Needs Market Makers

Market making is the mechanism that creates tight spreads and deep order books. Without professional market makers, BULK Exchange would have wide spreads and poor fill prices — making it uncompetitive with Hyperliquid and CEXes.

BULK’s approach is to remove barriers to market making rather than relying purely on organic liquidity:

• Zero maker fees during Genesis (30 days, any volume tier)
• Maker rebates at high tiers (−0.5 to −2.0 bps)
• A dedicated Alpha Program with additional revenue share
• 5–20ms execution that makes market making strategies viable at low latency
• Fair ordering that eliminates the adverse selection risk from being front-run

The Genesis Phase Window

Duration: First 30 days of mainnet (~June 1 – July 1, 2026)

Maker fees: 0 bps across all eight volume tiers

This is the highest-value window for market makers. During Genesis:

• Enter every maker trade at zero fee
• Build volume history for tier advancement
• Establish order book presence before post-Genesis competition intensifies
• Earn taker fees from any market orders that cross your quotes

A market maker who quotes aggressively during Genesis builds both volume history (better post-Genesis tier) and order book reputation (attracts more flow).

Post-Genesis Maker Rebates

After Genesis Phase ends, the standard fee schedule applies based on 14-day rolling volume.

Tier 6+ market makers earn a rebate on every maker fill — the exchange pays them to provide liquidity. This is standard for high-volume market makers on competitive venues.

The Alpha Program

The Alpha Program distributes an additional 7.5% of taker fee revenue per 30-day epoch to qualifying market makers.

Qualification: Any account can enroll. No KYC required.

Quality Score components:

Revenue calculation at $100M daily volume:

• Daily taker fees at 3% average: $300,000
• 30-day epoch total taker fees: $9,000,000
• Alpha Program pool (7.5%): $675,000
• Distribution: proportional to Quality Score

A market maker capturing 20% of the Alpha Program pool at $100M daily volume earns $135,000/epoch in additional income, on top of maker rebates.

Commission Fees (PFOF Alternative)

BULK Exchange will allow third-party integrators to set commission rates on top of base fees for their users.

Per the architecture documentation, the key design difference from traditional payment for order flow (PFOF):

BULK’s National Best Bid and Offer (NBBO) is maintained. No internalization occurs.

In traditional PFOF, orders are sometimes executed away from the best market price in exchange for payment to the broker. BULK’s commission fee structure allows integrators to earn revenue without compromising execution quality — orders still execute at BULK’s NBBO.

This means trading interfaces, bots, and integration platforms can earn revenue from BULK without disadvantaging their users.

Client SDK for Algorithmic Trading

BULK Exchange provides an open-source client SDK for programmatic integration.

The SDK provides:

• HTTP API for order submission, cancellation, and account management
• WebSocket streams for real-time order book, trades, and position updates
• Noise Protocol authenticated connections between the client and BULK validators

For HFT and market making at the level where 5–20ms latency matters, the SDK enables direct integration without routing through a browser interface.

Fair Ordering Advantage for Market Makers

Market makers on BULK Exchange have a specific structural advantage from the fair ordering system:

Cancels are always first. In BULK’s structural priority queues, cancellation orders are processed before any fills in every batch. This means if a market maker submits a cancel and a taker simultaneously crosses their quote, the cancel processes first — the market maker avoids the fill if they’ve already decided to revoke the quote.

This eliminates one of the most common adverse selection vectors in market making: the race between cancellation and fill when prices are moving.
