A custom stateful precompile can use the `is_static` parameter to determine if the call is executed in a static context (via `STATICCALL`), and thus decide if stateful operations should be done. Prior to version 0.36.0, the passed `is_static` parameter was incorrect -- it was only set to `true` if the call came from a direct `STATICCALL` opcode. However, once a static call context is entered, it should stay static. The issue only impacts custom precompiles that actually uses `is_static`. For those affected, the issue can lead to possible incorrect state transitions. Version 0.36.0 contains a patch. There are no known workarounds."}, {"lang": "es", "value": "SputnikVM, tambi\u00e9n llamado evm, es una implementaci\u00f3n en Rust de la m\u00e1quina virtual de Ethereum.
