This paper examines the legal qualification of Smart Contracts under Swiss law and gives an over-view over how Smart Contracts may interact with the fundamental rules of contract law. Furthermore, on the basis of this examination the need for legislative action with respect to Smart Contracts will be assessed.
It is concluded that the potential applications of Smart Contracts on the blockchain are vast and sound very promising. If applied in a sensible way this technology indubitably will lead to gains in efficiency of contract execution and lower transaction costs.
However, Smart Contracts will not prevent contractual disputes from arising. Consequently, parties will still resort to court actions. In these cases, Smart Contracts may tend to make things more complicated because while they may not eliminate the need for courts they limit the accessibility of courts for their parties via their self-enforcing nature.
Furthermore, while Smart Contracts may attempt to substitute law by code that does not mean that they will be able to render the law useless. There will still be need for mandatory law for various purposes, including, but not limited, to protect the parties from adverse consequences which the Smart Contract technology itself may produce.
