mvx_flash_loan_patterns

What problem does it solve?

This Skill provides a robust pattern for implementing atomic operations involving lending and borrowing assets within a single transaction, ensuring that all steps, from lending to repayment, are completed successfully or rolled back entirely.

Core Features & Use Cases

• Atomic Transactions: Guarantees that lending, execution of a callback, and repayment occur as a single, indivisible operation.
• Reentrancy Protection: Includes a guard to prevent recursive calls within the same operation.
• Shard Validation: Ensures operations are confined to the same blockchain shard to maintain atomicity.
• Endpoint Validation: Verifies that the callback endpoint is not a built-in function, preventing bypass of repayment logic.
• Repayment Verification: Confirms that the contract balance is sufficient for repayment after the callback.
• Use Case: Ideal for implementing flash loans, atomic swaps, or temporary asset grants where immediate repayment is critical.

Quick Start

Implement the atomic lend-execute-verify pattern using the provided Rust code snippet.
