VendorvyperlangProductvyperDiscoveredSep 18, 2023UpdatedNov 21, 2024

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine (EVM). Starting in version 0.2.9 and prior to version 0.3.10, locks of the type @nonreentrant("") or @nonreentrant('') do not produce reentrancy checks at runtime. This issue is fixed in version 0.3.10. As a workaround, ensure the lock name is a non-empty string.
