Smart Contracts: What are they and what are their legal implications?

Smart Contracts: What are they? 

The Smart Contracts (smart contracts) are, in fact, self-executing computer programmes that operate using blockchain technology.

For clarification purposes only, we would like to point out that blockchain is a distributed ledger technology that stores data in blocks linked together in a secure and transparent manner. Each block contains a set of transactions and is linked to the previous block using cryptography, creating an immutable chain of records that is shared and verified by multiple nodes in a decentralised network.

Smart contracts, which utilise this technology, contain rules and agreements established between the parties involved, and are executed automatically when predefined conditions are met. They are executed by a programme designed to ensure the transparency, immutability and security of transactions.

Key features of smart contracts

1. Automatic enforcement: They run automatically when the specified conditions are met.

2. Transparency: All parties have access to the terms of the contract and the transactions carried out.

3. Immutability: Once a contract or transaction has been recorded, it cannot be amended.

4. Security: They use cryptography to secure transactions and information.

Smart contracts represent a significant innovation in the way agreements are drawn up and executed. However, their widespread adoption is hampered by legal and regulatory challenges that need to be addressed to ensure their validity and enforceability across different jurisdictions. The validity of smart contracts may vary depending on the jurisdiction in question. In many countries, they are not yet fully regulated or recognised as legal equivalents of traditional contracts. Collaboration between technologists and legislators will be crucial to developing a legal framework that allows us to make the most of the benefits of this emerging technology.

Regulation of Smart Contracts in Spain

In Spain, smart contracts are not yet subject to specific, detailed regulation. However, their use and application fall within the scope of the general laws governing the general theory of contracts, as well as the limited regulation we have regarding blockchain technology.

These are the most important aspects of the legal framework in Spain:

General legal framework:

1. Civil Code and Commercial Code: Smart contracts must comply with the general principles of contracts set out in the Civil Code and the Commercial Code. This includes elements such as consent, the subject-matter and the consideration of the contract.
2. Law on Information Society Services and Electronic Commerce (LSSI-CE): It regulates the provision of services via electronic means and, although it does not explicitly refer to smart contracts, it applies to digital transactions.
3. General Data Protection Regulation (GDPR): The implementation of smart contracts must comply with data protection regulations, particularly with regard to the collection, processing and storage of personal data.

Specific issues and challenges:

1. Validity and legal recognition: Smart contracts must meet the legal requirements of traditional contracts in order to be recognised as valid. This includes the consent of the parties, the parties’ capacity to enter into a contract, and a lawful and specific subject-matter.
2. Testing and implementation: In Spain, smart contracts can be submitted as evidence in court and will be fully valid. However, the technical understanding required of professionals currently practising in the field can be a challenge and a drawback.
3. Liability and risks: Liability in the event of coding errors, hacking or failures in the automated execution of the contract must be clearly defined in the contract. It is important to bear in mind that parties who are not traditionally party to contracts (such as developers, etc.) are involved.
4. Jurisdiction and applicable law: Determining the jurisdiction and the law applicable to smart contracts can be complex, particularly in international transactions. It is crucial to set out these matters in the contract itself.

That said, and although the framework is still in its very early stages, Spain is a country that is making rapid progress towards creating a framework that will enable a faster and more secure roll-out of this new form of contracting. We already have a number of initiatives under way that are committed to this:

1. Regulatory sandbox: Spain has launched a regulatory sandbox for fintech, which includes blockchain technology and smart contracts. This controlled environment enables companies to test new technologies under the supervision of the regulatory authorities, thereby facilitating the development of an appropriate regulatory framework.
2. European bills and directives: Spain is closely monitoring the European Union’s initiatives relating to the regulation of blockchain technology and smart contracts. The proposed Regulation on Markets in Crypto-Assets (MiCA) is an example of how European regulation will influence Spanish legislation.

Practical examples of smart contracts

To gain a better understanding of how they work, we can look at some examples of smart contracts that are already in use today:

(a) Automation of insurance payments

In the insurance sector, smart contracts can automate the payment of claims. For example, in the case of flight insurance, a smart contract can be programmed to automatically check whether a flight has been delayed or cancelled. 

b) Supply chain management

 Within the supply chain, smart contracts can help track products from production through to delivery, ensuring that every stage of the process is carried out in accordance with the agreed terms.

 (c) Enforcement of tenancy agreements

Smart contracts can simplify and automate property rental processes, from the payment of rent to the return of the security deposit.

In summary, smart contracts offer innovative and efficient solutions for a range of industries, from insurance and supply chain management to property. Their ability to automate and ensure the execution of contractual agreements reduces the need for intermediaries and minimises the risk of errors and disputes, bringing transparency and efficiency to business processes.

We will see how its adoption develops over the coming years and decades, but with the rise of AI and blockchain technology, we can safely say that certain sectors will quickly embrace this new form of contracting.
