Contract: Develop Gas Estimation and Invocations Simulation Wrapper

[EDOHWARES]

Description

Build a helper contract that simulates events and calculates gas consumption for arbitrary invocations.

Current Problem

Complex multi-contract invocations frequently fail on-chain due to gas budget exhaustion, and developers lack tools to pre-calculate accurate resource fees.

Proposed Solution

Build a simulation runner contract that runs target methods in dry-run mode and calculates CPU, RAM, and storage fee footprints.

Technical Tasks

• Implement read-only execution wrappers inside a simulation helper contract
• Parse result buffers to extract gas and resource footprint metrics
• Build estimation formulas accounting for Stellar ledger transaction fees
• Write test cases asserting estimates against actual runtime executions

Acceptance Criteria

• Invocations report resource footprints without performing actual state writes
• Estimator reports match actual on-chain executions within a 5% margin
• Simulation handles out-of-gas exceptions gracefully, returning details on where it failed

Testing Requirements

• Benchmark gas estimates against real execution runs of several contracts
