Too Long; Didn't Read
All the projects that we are going to analyze are decentralized platforms and as such they interface through an entry point, which in all cases is always represented by the wallet. For simple operations the cost is lower, therefore less than 1 dollar, while for complex ones even several tens of dollars. In order not to have any kind of gas side problem, is to reserve at least 1 ETH as a cost to pay all the fees, so in this way we can operate without problems. The cost of fees is variable and is not determined a priori, so if we have to interact with a protocol we first consider and estimate how much to invest.
