multiversx-flash-loan-patterns

To implement a secure flash loan on MultiversX, use an atomic transaction pattern that temporarily lends assets, executes external logic via a callback, and verifies repayment within a single block.

Secure atomic transactions on MultiversX require reentrancy guards, same-shard validation, endpoint validation, and strict repayment verification to prevent exploits during the callback execution.

A flash loan transaction reverts if repayment fails because the lending, execution, and verification steps are designed as a single indivisible atomic transaction, ensuring the state returns to its original position.

Yes, atomic operations can be used for temporary grants or atomic swaps with verification, allowing assets to be borrowed and conditionally returned within the same transaction without needing a standalone flash loan.

Yes, same-shard validation is an essential security guard for MultiversX flash loans, ensuring that the lending, callback execution, and repayment processes occur on the same shard for atomic consistency.

The multiversx-flash-loan-patterns skill provides a secure and atomic pattern for implementing flash loan functionalities, ensuring safe temporary lending, callback execution, and repayment verification on MultiversX.
