Implement Custom Error Code Mappings for Compact Reverts

• Category: Smart Contract: Security & Gas Optimization
• Task ID: SC-SEC-063

Description

This issue is dedicated to the technical design, implementation, and rigorous auditing of 'Implement Custom Error Code Mappings for Compact Reverts' inside the Lance marketplace ecosystem, specifically focusing on the Smart Contract: Security & Gas Optimization component. As a Soroban smart contract task, the contributor must design robust instance or persistent storage allocations, ensure safe checked math operations, and write high-coverage unit tests within the Rust cargo test harness. The compiled WASM footprint must fit comfortably within standard block boundaries. Ensure that your implementation strictly adheres to the project's architectural guidelines, features self-documenting code with comprehensive inline annotations, and provides solid verification proofs. Any modifications to state variables must undergo strict validation before commits.

Requirements

• Analyze compiler options, gas boundaries, and security layouts for Implement Custom Error Code Mappings for Compact Reverts.
• Implement reentrancy locks, transient variables, or compiler flag profiles appropriately.
• Compress state representation using packed structs to reduce persistent ledger bytes.
• Exhaustively verify gas consumption of core actions via automated benchmark tests.

Acceptance Criteria

• WASM contract sizes are verified to be under 40KB.
• Execution costs for releases and refunds drop by at least 15% in gas benchmarks.
• Strict re-entrancy unit tests correctly trigger panic aborts on simulated re-entrant calls.
