The point of this photo is people to realize that Smart contracts are not the Blockchain. Smart contracts are off chain and do not rely on the Blockchain decentralised security but need additional cyber security. If you can recognize in Avalanche network the subnets require support from other subnet in order to run so enjoy more decentralised security. Interacting with any smart contract it is ok but people must know the risks of it. Smart contracts are not designed for high value finance but the main design for smart contracts is non financial functionality and one time use. For example: signing a contract between two or more parties and condition to do something like unlock or execute any condition of the traditional contracts.
