To work around this, parties can build an emergency shutdown mechanism into the smart contract so that the code reflects the parties` intent to be bound and prevent potential hacks. Even if the parties do not incorporate an emergency exit function, they may refer to other circumstances other than the code to prove their intent to be bound by the code, but not to the hacking event.209 For example, without malicious evidence, the parties could show how much they have invested in creating accurate, rigorously tested computer code for reliable smart contracts.210 In addition, Parties could refer to previous transactions. that have been successfully executed and are similar to the smart contract in question, as well as show how they were severely damaged by the hack itself. However, the Convention on Contracts for the International Sale of Goods (CISG) is the standard rule when it comes to most contracts for the international sale of goods between parties to the CISG, so it is worth investigating what the UN Convention on Contracts for the International Sale of Goods has to say about the legality of smart contracts. Blockchain-based smart contracts involve more than the „if“. then“ in vending machines. This subsection focuses mainly on the provisions of the United Nations Convention on Contracts for the International Sale of Goods in section II (art. 14-24), but also contains some discussion of the articles in section I and section III to show the rules for concluding the contract by offer and acceptance. The provisions of the United Nations Convention on Contracts for the International Sale of Goods on offers and acceptance are particularly critical for the subsequent analysis that smart contracts may be valid under the United Nations Convention on Contracts for the International Sale of Goods. In an export-oriented country like Australia, it is important to have robust systems for transporting goods such as wine, iron ore and grain across borders.

Of course, much of the conversation about the benefits of blockchain and cross-border smart contracts can simply be created by a growing number of startups in the blockchain industry. As one industry insider noted, all the promising benefits of smart contracts for international trade will take time „because the existing financial infrastructure has been in place for decades and because it is difficult to get competing institutions to cooperate.“ 11 But the legal and commercial industry responded to the hype, hoping to capitalize on its promise. Courts tend to follow the internationalist approach of the majority of academics, with regard to the validity clause of Article 4, it is also appropriate to follow the internationalist approach of the hypothetical smart contract above, which is also defined in the context of the US judicial system. Finally, there is also a subjective element of the conclusion of the contract under article 14 CISG, since it presupposes some manifestation of the supplier`s intention to be bound by the offer in case of acceptance. Article 8 explains how this intent can be demonstrated: Finally, given the wide range of smart contracts and the different types of agreements that can be embedded in them, the question arises as to when exactly in the spectrum a smart contract is considered valid and binding.58 This question often revolves around the applicable law that determines the issue and factual circumstances of the case. Therefore, in section III, we turn to the standard law that applies to contracts for the international sale of commercial goods between signatory states: the United Nations Convention on Contracts for the International Sale of Goods (CISG). Under the United Nations Convention on Contracts for the International Sale of Goods, the intentions of the parties are of paramount importance for the conclusion of the contract, so that the Convention allows the parties to „modify“ the effects of the other provisions on the conclusion of the contract, provided that their intention to be bound by the contract is clear.167 Conversely, even if a bid is sufficiently specific and addressed to at least one specific person: A proposal to create a contract is not considered a bid if it cannot be demonstrated that the bidder intended to be bound by the bid.168 Indeed, „a proposal is not always intended to conclude a contract, but may perhaps aim to enter into negotiations on a sale.“ 169 Thus, if a tenderer can prove its intention to be bound by a contractual tender even though it is a purely coded tender, it is easier to argue that it is a tender within the meaning of Article 14. Due to the ambiguity of the use of smart contracts and the possibility of a violation, it is therefore important to discuss what exactly the CISG has to say about smart contracts. In addition, smart contracts can help reduce and thus promote the transaction costs of international trade. According to article 18 CISG, acceptance of a target addressee is „a statement or other conduct of the target recipient expressing its consent to an offer“.

103 Consequently, absolute silence or non-compliance by the addressee with a previous expression of interest does not constitute acceptance.104 Furthermore, acceptance takes effect „as soon as the tenderer receives the declaration of consent.
