However, due to the decentralised nature of the blockchain on which they are based, a series of challenges have emerged related to vulnerabilities in their programming that, given their particularities, could have (and have already had) a very high economic impact. This article provides a holistic view of security challenges associated with smart contracts, as well as the state of the art of available public domain tools.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttps://doi.org/10.3390/e22020203https://www.mdpi.com/1099-4300/22/2/203open accessblockchainEthereumsecure developmentsecuritysmart contractsInternet (Informática)Seguridad informática3325 Tecnología de las Telecomunicaciones
