Fees & Incentives

Trading Fees

Strike uses a maker/taker fee model:

Role	Fee	Rationale
Maker	0 bps (+ rebate)	Incentivize liquidity provision
Taker	30 bps (configurable)	Revenue for protocol + maker rebates

• Maker = order that rests on the book (adds liquidity)

• Taker = order that crosses the book (removes liquidity)

• Fees are deducted at claim time, not during batch clearing (keeps clearing gas-efficient)

• Maker rebates are funded from a portion of taker fees

Protocol Revenue

A portion of taker fees goes to the protocol fee collector address. This funds development and operations.

Resolver Bounty

Every market has a resolver bounty funded by the market creation bond (e.g., 0.005 BNB):

• Paid to whoever successfully calls resolveMarket() with valid Pyth data

• Incentivizes permissionless resolution — anyone can earn by resolving expired markets

• If the market auto-cancels (no resolution within 24h), the bond is returned to the market creator

Pruner Bounty

Expired or stale orders consume storage. A small bounty incentivizes cleanup:

• Each order deposits a small order bond on placement

• Anyone can call pruneExpiredOrders() to remove expired orders

• The pruner receives the order bond as compensation

• This keeps the orderbook clean without relying on centralized maintenance

Anti-Spam

Mechanism	Purpose
Minimum lot size	Prevents dust orders
Order bond	Economic cost to spamming orders (refunded on cancel/fill, paid to pruner on expiry)
Per-tick order caps	Bounds worst-case clearing gas cost

Market Creation Bond

Creating a market requires a bond that covers:

• Resolver bounty

• Gas cost buffer for keeper operations

• Returned (minus resolver bounty) when the market resolves or cancels
