Priority Fee Market

Rollr operates a transparent priority fee marketplace that determines bundle execution order. Higher priority fees increase the likelihood of front-of-block placement and faster execution.

How Priority Fees Work

Priority fees are additional payments searchers make to validators for preferential transaction ordering. In Rollr, these fees are used to rank bundles in the execution queue.

Base Fee

Minimum fee required for bundle submission, covers relay operational costs and basic validator compensation.

5,000 lamports

Priority Fee

Additional fee paid to improve execution priority and compete for front-of-block placement.

Variable

Fee Calculation

Total Bundle Cost = Base Fee + (Priority Fee × Transaction Count)

Example:
- Base Fee: 5,000 lamports
- Priority Fee: 10,000 lamports
- Transactions: 3

Total Cost = 5,000 + (10,000 × 3) = 35,000 lamports

Priority Tiers

Premium

50k+ lamports

Guaranteed front-of-block execution with <100ms latency. Ideal for time-sensitive MEV opportunities like liquidations and arbitrage.

Standard

10-50k lamports

High-priority execution with typical placement in the first 20% of the block. Suitable for most trading strategies.

Economy

5-10k lamports

Standard execution priority with no placement guarantees. Good for non-time-sensitive operations.

Dynamic Fee Estimation

Rollr provides real-time fee estimation API to help optimize your priority fee bids based on current network conditions.

Best Practices

Monitor Network Congestion

Use fee estimation API to adjust bids dynamically based on current network conditions and competition.

Calculate Break-Even Points

Ensure priority fees don't exceed expected MEV profit. Implement automated bid optimization based on bundle profitability.

Start Conservative

Begin with economy tier fees and increase only when necessary. Track execution success rates to optimize spending.

Implement Fail-safes

Set maximum fee limits to prevent overpaying during network spikes or bidding wars.
