#087: Optimize Gas Fees for Bulk Execution

Category: [CONTRACT]
Difficulty: ● MEDIUM
Tags: soroban, optimization, gas, bulk-payment, performance

Description

Refactor the execute_batch and execute_batch_partial functions in the bulk payment contract to minimize CPU and RAM instruction consumption. The goal is to reduce the overall transaction fee for employers when processing large payroll batches.

Acceptance Criteria

• Identify bottlenecks in the current execute_batch implementation using Soroban simulation.
• Reduce the number of storage reads/writes per payment operation.
• Verify that the optimized code maintains 100% data integrity and atomicity.
• Benchmark before/after gas usage for a 50trace payment batch.
