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.
Priority Fee
Additional fee paid to improve execution priority and compete for front-of-block placement.
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 lamportsPriority Tiers
Premium
50k+ lamportsGuaranteed front-of-block execution with <100ms latency. Ideal for time-sensitive MEV opportunities like liquidations and arbitrage.
Standard
10-50k lamportsHigh-priority execution with typical placement in the first 20% of the block. Suitable for most trading strategies.
Economy
5-10k lamportsStandard execution priority with no placement guarantees. Good for non-time-sensitive operations.

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.
