EU Data Act: Impact on Smart Contracts
Learn about the impact of the EU Data Act on smart contracts in the European blockchain ecosystem. Find out key rules, challenges, and solutions for compliance.
Save 90% on your legal bills
The EU Data Act, effective January 11, 2024, will significantly impact smart contracts in the European blockchain ecosystem. Here's what you need to know:
- The Act requires a "kill switch" for automated data-sharing agreements, challenging the immutability of smart contracts
- New rules on data access and use affect smart contract operations
- Compliance may require redesigning smart contracts and blockchain systems
Key impacts and solutions:
| Impact | Solution |
|---|---|
| Need for safe termination | Implement "stop button" functionality |
| Enhanced security requirements | Improve contract security and access controls |
| Data protection concerns | Design contracts to safeguard sensitive information |
| Compliance with data sharing rules | Align contract logic with legal requirements |
Companies must prepare by September 12, 2025, when the rules take effect. While challenging, the Act may lead to standardization and increased trust in smart contracts across the EU.

2. Problems with the EU Data Act for smart contracts
2.1 How the Data Act defines smart contracts
The EU Data Act's definition of smart contracts is too broad. It might include computer programs that aren't usually seen as smart contracts. This lack of clarity could slow down blockchain growth in the EU.
2.2 Main rules for smart contracts
The Data Act sets these rules for smart contracts in data-sharing:
| Rule | Description |
|---|---|
| Safety | Prevent errors and outside tampering |
| Stopping ability | Must be able to stop safely |
| Data keeping | Save data and keep things running |
| Access limits | Control who can use the contract |
| Agreement match | Follow the data-sharing deal |
These rules aim to make things safer, but they're hard for people who make and use smart contracts.
2.3 Clashes with blockchain basics
The Data Act doesn't fit well with how blockchain works:
| Blockchain Idea | Data Act Rule | Problem |
|---|---|---|
| Can't be changed | Must have stop button | Goes against blockchain's core idea |
| Open to all | Must limit access | Doesn't work for public blockchains |
| No central control | One group can stop it | Against blockchain's spread-out nature |
These clashes could cause:
- Less new ideas: Tough rules might stop companies from using smart contracts.
- Higher costs: Following the rules could be expensive.
- Limited reach: Companies might have to block users from some places.
- New risks: Adding ways to stop contracts could make them less safe.
The blockchain world needs to find a way to follow the rules while keeping what makes blockchain special. This is key for smart contracts to work in the EU.
3. Ways to follow the rules
3.1 Changing smart contract design
To meet EU Data Act rules, smart contract makers need to change their designs:
| Change | Purpose |
|---|---|
| Add access controls | Limit who can use the contract |
| Improve error prevention | Stop outside tampering |
| Add safe stop functions | Allow contracts to be stopped safely |
| Include data saving features | Keep records and keep things running |
| Match contract logic with data deals | Follow the terms of data-sharing agreements |
These changes aim to make contracts safer and follow the law.
3.2 Keeping blockchain features while following rules
It's hard to keep blockchain ideas while following rules. Developers can:
| Method | How it helps |
|---|---|
| Use permission controls | Control access at the top level |
| Make contracts check for rule-following | Only run when rules are met |
| Store some data off-chain | Keep sensitive info separate |
| Mix on-chain and off-chain parts | Balance blockchain and rule-following |
These methods help keep blockchain benefits while meeting Data Act needs.
3.3 Better data protection
To protect data better in smart contracts:
| Protection method | What it does |
|---|---|
| Use encryption | Keep sensitive data secret |
| Use zero-knowledge proofs | Do math without showing the data |
| Add access control lists | Manage who sees what data |
| Use data minimization | Only use necessary data |
These steps help keep private info safe in smart contract systems.
3.4 Working together on standards
Working together helps make smart contracts that follow rules:
- Join European standard-making groups
- Take part in industry groups to make best practices
- Help with open-source projects that follow rules
- Share what you know at meetings and online talks
This teamwork helps everyone use smart contracts that follow the rules.

4. Effects of the EU Data Act
4.1 Good things about following the rules
The EU Data Act's impact on smart contracts has some good points:
| Good Point | What it Means |
|---|---|
| Common standards | Makes it easier for everyone to use smart contracts |
| More open reporting | Builds trust in crypto companies |
| Better user safety | Protects people from risks in smart contracts |
4.2 Problems and risks
The EU Data Act also brings some challenges:
| Challenge | Impact |
|---|---|
| Slower uptake | Harder for companies to use smart contracts in Europe |
| More work to follow rules | Takes more time and money to make smart contracts |
| Clashes with blockchain ideas | Goes against some key blockchain features |
| Trouble working together | Different rules might make it hard for systems to work together |
4.3 Pros and cons table
| Pros | Cons |
|---|---|
| Same rules across EU | Slower use in Europe |
| More open reporting | More work to follow rules |
| Better user safety | Goes against some blockchain ideas |
| Clearer standards | Hard for different systems to work together |
| More blockchain use in EU | Costs more to make |
| Might be used more widely | Takes longer to put in place |
| Easier to use smart contracts | Might slow down new ideas |
| Fits with data protection goals | Hard to keep up with rules |
5. Getting ready to follow the rules
5.1 Important dates
The EU Data Act has key dates for businesses:
| Date | What happens |
|---|---|
| January 11, 2024 | Data Act starts |

Companies have 20 months to get ready before the rules start.
5.2 What companies need to do
To get ready for the EU Data Act, companies should:
1. Check current practices: Look at how they share and use data now.
2. Make a plan: Write down what needs to change by September 2025.
3. Update contracts: Change agreements to fit new data sharing rules.
4. Change tech: Fix products and services to follow new data rules.
5. Look at other rules: Make sure to follow this law and others like GDPR.
Companies that don't follow the rules might have to pay up to €20 million or 4% of their yearly money. It's smart to start following the rules early.
Main things to focus on:
| Area | What to do |
|---|---|
| Data sharing | Make it easy for users to get their data |
