EU Data Act Article 36 Smart Contract Controls

What should teams archive when an Article 36 smart contract is terminated or deactivated under the Data Act?

The Data Act context is the starting point for this answer. Article 36 requires the possibility to archive transactional data, smart contract logic, and code where the smart contract must be terminated or deactivated, so that past operations on the data remain auditable. The archiving plan should be designed before deployment, because a terminated contract may no longer expose the same operational state.

The archive does not need to become a public dump of sensitive data. It should preserve enough evidence to reconstruct what the smart contract did, under which agreement version, with which permissions, and with which data-sharing transaction history, while respecting separate confidentiality, security, and data protection controls.

  • Archive code version, deployed address or identifier, agreement version, configuration, and privileged-action logs.
  • Preserve transaction records needed to audit past data-sharing operations.
  • Document continuity steps for access, dispute handling, and evidence retention after deactivation.

EU Data Act Article 36 Smart Contract Controls

Does Article 36 make the smart contract legally control the data-sharing agreement under the Data Act?

The Data Act context is the starting point for this answer. No. Article 36 requires consistency between the smart contract and the data-sharing agreement it executes, but Recital 104 says applicable civil, contractual, and consumer protection law remains unaffected by using smart contracts for automated execution. Teams should avoid saying that the code itself resolves legal rights, consent, liability, or contract interpretation.

The practical requirement is alignment. The code, interface, access permissions, termination mechanism, and archive record should match the agreed terms. If the written agreement changes, the smart contract control record should show whether code or configuration changes are needed before continued use.

  • Do not describe Article 36 as creating self-enforcing legal validity for all agreement terms.
  • Check that code paths and agreement clauses say the same thing about access, use conditions, interruption, and termination.
  • Keep a traceable link between agreement versions, smart contract versions, and deployment approvals.

What conformity evidence does Article 36 require before deployment or use under the Data Act?

The Data Act context is the starting point for this answer. The vendor of a smart contract, or the deployer for others where there is no vendor, must perform a conformity assessment with a view to fulfilling the Article 36 essential requirements and issue an EU declaration of conformity when those requirements are fulfilled. Drawing up that declaration makes the actor responsible for compliance with the Article 36 essential requirements.

The evidence file should therefore be more than a security review. It should include the Article 36 requirement mapping, test results, access-control design, termination and interruption test evidence, archive plan, agreement-consistency review, version identifiers, approver sign-off, and the EU declaration of conformity.

  • Create a requirement-by-requirement conformity checklist for Article 36(1)(a) through Article 36(1)(e).
  • Attach evidence from engineering, security, product, and legal review rather than relying on a generic audit statement.
  • Keep the EU declaration of conformity tied to the smart contract version and agreement context it covers.

How do harmonised standards and common specifications affect Article 36 conformity under the Data Act?

The Data Act context is the starting point for this answer. Article 36 provides a presumption of conformity where a smart contract meets harmonised standards, or relevant parts of them, whose references are published in the Official Journal of the European Union, to the extent those standards cover the essential requirements. It also allows the Commission to adopt common specifications as a fallback where the listed conditions are met.

The wider Data Act standardisation work is active, but teams should not claim that a future or adjacent standard automatically proves Article 36 compliance. Use the Data Act text as the binding source, then track whether an Article 36 harmonised standard or common specification has been published and which requirement it covers.

  • Treat harmonised standards as conformity support only for the Article 36 requirements they actually cover.
  • Do not cite general data-space standards as proof of Article 36 smart-contract conformity unless the source covers Article 36.
  • Maintain a standards watch entry for Official Journal references, common specifications, and affected smart contract versions.

EU Data Act Article 36 Smart Contract Controls

What should an Article 36 smart contract control record contain under the Data Act?

The Data Act context is the starting point for this answer. A practical record should let a reviewer understand scope, ownership, controls, and evidence without reconstructing the project from code comments. The record should identify the data-sharing agreement, the smart contract version, the responsible actor, each Article 36 requirement, the evidence used to assess it, and the declaration or standards basis relied on.

The record should also show what changed over time. Article 36 controls can become stale when agreement terms change, access roles are modified, a new deployer takes over, code is upgraded, termination functions are adjusted, or relevant standards or common specifications are published.

  • Scope fields: agreement, data made available, parties, vendor or deployer role, contract version, and smart contract identifier.
  • Control fields: robustness tests, access-control model, interruption and termination process, archive plan, and agreement-consistency review.
  • Evidence fields: code version, test results, approvals, privileged-action logs, EU declaration of conformity, and standards or common-specification references.

What is the most common Article 36 mistake to avoid under the Data Act?

The Data Act context is the starting point for this answer. The common mistake is treating Article 36 as a blockchain policy page instead of a concrete conformity and control obligation for smart contracts executing data-sharing agreements. Generic statements about security, immutability, decentralisation, or automation do not answer the Article 36 questions.

A defensible answer identifies the covered agreement, responsible actor, exact smart contract functions, access-control layers, termination and interruption path, archive plan, agreement-consistency check, conformity assessment, and EU declaration status. It also avoids uncited claims about fines, effective dates, or legal effects that are not needed to answer the Article 36 control question.

  • Avoid penalty numbers or deadline claims on this FAQ unless a cited source directly supports them.
  • Avoid claiming that a smart contract can override the parties' agreement or applicable contract law.
  • Avoid relying on future standards as current conformity proof unless their Official Journal or common-specification status is verified.

What Data Act source evidence should teams keep for the Article 36 Smart Contract Controls FAQ decision?

Keep the source evidence that shows why Article 36 applies and how the control decision was made. At a minimum, store the cited Data Act clause, the smart contract role identified by Article 36, the agreement version, the specific control tested, and the conformity evidence used to support the answer.

Also keep the decision date, the reviewer or approver, and the linked implementation artifact so future reviewers can see how the Article 36 control position was reached and whether the same conclusion still fits the current agreement and code version.

  • Keep the cited Data Act source URL and the exact Article 36 requirement that was used.
  • Keep the smart contract version, agreement version, and the evidence used for conformity assessment.
  • Keep the reviewer or approver and the date of the decision so the record can be traced later.

How should teams assign ownership for Data Act Article 36 Smart Contract Controls implementation work?

Assign one accountable owner for the Data Act Article 36 control record itself: the vendor of the smart contract or, where there is no vendor, the person deploying smart contracts for others in the context of executing the agreement. That owner should be responsible for the conformity assessment, the EU declaration of conformity, and the control record that links the smart contract to the agreement.

Other teams can contribute evidence, but the owner should be the person or function that can approve code, access control, interruption, archiving, and agreement changes. When responsibilities are split, keep the legal, product, security, and engineering contributors named separately so the accountable owner remains clear.

  • Make the vendor or deployer the single accountable owner for the Article 36 control file.
  • List legal, engineering, security, and product contributors as consulted teams, not as owners.
  • Change ownership whenever the vendor or deployer role changes, or when the agreement and code move to a new operational owner.

EU Data Act B2B Data Sharing Compensation

Can a data holder charge compensation for mandatory B2B data sharing under the EU Data Act?

Yes, but the Data Act does not give data holders an open-ended right to set deterrent access fees. Article 9 says compensation agreed between a data holder and a data recipient for making data available in B2B relations must be reasonable and non-discriminatory, and it may include a margin.

The first scoping question is whether Chapter III applies: the data holder must be obliged in a B2B relationship to make data available under Article 5 or under applicable EU law or national legislation adopted in accordance with EU law. If the sharing is voluntary, consumer-facing, business-to-government, or cloud switching, use the rules for that workflow instead.

  • Identify the data holder, the data recipient, the legal sharing obligation, and the dataset before discussing price.
  • State whether the request is under Article 5 or another mandatory B2B sharing obligation covered by Chapter III.
  • Do not publish a standard fee schedule unless the underlying cost basis and recipient treatment can satisfy Article 9.

Commission explainer confirms that mandatory B2B data-sharing terms must be fair, reasonable, and non-discriminatory and that data holders may request reasonable compensation.

EU Data Act B2B Data Sharing Compensation

What cost basis can be used to calculate reasonable compensation under Article 9 under the Data Act?

The Data Act context is the starting point for this answer. Article 9 points to concrete inputs, not a generic market-price uplift. The parties must take into account costs incurred in making the data available, especially formatting, electronic dissemination, and storage. They must also consider investments in collecting and producing the data where applicable, including whether other parties contributed to obtaining, generating, or collecting the data.

The compensation may also depend on the volume, format, and nature of the data. That allows different calculations for materially different data requests, but it does not support unexplained charges, punitive access fees, or prices that cannot be tied back to the Article 9 inputs.

  • Keep a calculation worksheet showing formatting, dissemination, storage, and any applicable data collection or production investment inputs.
  • Record how volume, format, and data nature affected the amount charged.
  • Separate recurring platform costs from the incremental work needed to make the requested data available.

Can the data holder add a margin to B2B data sharing compensation under the Data Act?

Article 9 says compensation may include a margin, but the margin still sits inside the rule that the overall compensation must be reasonable and non-discriminatory. The Data Act therefore supports a documented margin analysis, not an arbitrary profit line or a charge designed to make access unattractive.

The margin position should be checked against the recipient category. Where the data recipient is an eligible SME or not-for-profit research organisation, Article 9(4) limits compensation to the costs incurred in making the data available, which excludes a margin above those cost elements for that protected recipient category.

  • Show the margin separately from direct making-available costs so it can be reviewed.
  • Apply the same margin logic to similarly situated recipients unless a documented difference justifies different treatment.
  • Remove the margin for recipients covered by the SME or not-for-profit research organisation cap.

How does the SME and startup protection affect Data Act compensation?

The Data Act gives protected treatment to data recipients that are SMEs or not-for-profit research organisations, provided the recipient does not have partner enterprises or linked enterprises that do not qualify as SMEs. For those recipients, compensation cannot exceed the costs incurred in making the data available under Article 9(2)(a).

The grounding materials support SME treatment, but not a separate startup-only threshold or discount. A startup should therefore be assessed through the Data Act SME test and any partner or linked enterprise facts, rather than by assuming that all startups receive a special fee rule.

  • Ask the recipient to confirm SME or not-for-profit research organisation status when relying on the cap.
  • Check partner and linked enterprise facts before applying the protected-recipient limit.
  • Do not add a startup discount, revenue threshold, or headcount threshold unless the company has a separately sourced SME classification process.

What information must the data holder give the data recipient about the compensation calculation under the Data Act?

The Data Act context is the starting point for this answer. The data holder must provide the data recipient with information setting out the basis for calculating compensation in enough detail for the recipient to assess whether Article 9(1) to 9(4) are met. A single line item such as "data access fee" is unlikely to be useful for that assessment.

A practical disclosure should show the relevant data scope, cost categories, investment assumptions where used, volume or format factors, margin treatment where applicable, and whether the SME or not-for-profit research organisation cap was assessed.

  • Give the recipient enough detail to test reasonableness, non-discrimination, cost categories, margin, and any protected-recipient cap.
  • Keep the same calculation basis in the quote, contract schedule, invoice support, and dispute file.
  • Avoid exposing trade secrets in the calculation notice; disclose the compensation basis at the level needed to assess Article 9 compliance.

How do unfair contractual terms interact with Data Act compensation clauses?

The Data Act context is the starting point for this answer. Compensation clauses should be reviewed together with Chapter IV on unfair contractual terms. Article 13 applies to contractual terms concerning access to and use of data, or liability and remedies for breach or termination of data-related obligations, when an enterprise unilaterally imposes the term on another enterprise.

A compensation term is higher risk when it is take-it-or-leave-it, cannot be meaningfully negotiated, lets the imposing party interpret conformity alone, limits remedies inappropriately, or allows substantial price changes without a valid reason and termination right. Article 13 does not assess adequacy of price against data supplied, but surrounding terms can still be unfair.

  • Review data-sharing price clauses, change rights, remedies, termination rights, and conformity decisions as one package.
  • Keep evidence that the recipient had a real opportunity to negotiate if the term was not intended to be unilateral.
  • Do not use compensation language to override the mandatory Chapter III safeguards; Article 8 makes such exclusions non-binding.

Can a data holder use trade secrets or security concerns to increase or refuse compensation-based access under the Data Act?

Trade secrets are a safeguard issue, not a blank cheque for compensation. The Commission FAQ explains that a data holder may require confidentiality and secrecy safeguards before disclosure, and the Data Act allows withholding, suspension, or exceptional refusal only under specific conditions. A trade secret label alone is not enough to block the access right.

Where trade secret protection affects cost, separate the protection measure from the compensation calculation. For example, confidentiality arrangements, strict access protocols, or technical controls may affect the effort needed to make data available, but the data holder should still be able to show how those measures relate to the requested data and Article 9 cost basis.

  • Identify trade secret data and agree proportionate confidentiality or technical safeguards before disclosure.
  • Use withholding, suspension, or refusal only where the Data Act conditions are met and the decision is documented.
  • Do not convert trade secret concerns into an unexplained surcharge or an unsupported refusal.

What evidence should a data holder keep for a reasonable compensation decision under the Data Act?

Keep a file that lets someone else reconstruct the Data Act Article 9 decision. The record should show the mandatory sharing trigger, the recipient category, the cost items used, any margin analysis, and the disclosure given to the recipient. It should also show why similar recipients were treated the same or differently.

Because Article 10 allows certified dispute settlement bodies to resolve FRAND and compensation disputes, teams should also keep the material they would need if the amount is challenged: the worksheet, recipient correspondence, and the rationale for any SME or research-organisation cap.

  • Retain the calculation worksheet, the recipient notice, and the legal basis for the sharing obligation.
  • Keep records that show how non-discrimination was checked between comparable recipients.
  • Preserve the documents that support any SME, not-for-profit research organisation, or no-margin position.

EU Data Act B2B Data Sharing Compensation

What should teams avoid when setting B2B data sharing compensation under the Data Act?

Avoid treating the Data Act as if it supplies a fixed tariff table. The grounding sources support cost categories, margin possibility, protected-recipient caps, calculation transparency, and dispute routes; they do not support invented per-API-call fees, percentage-of-revenue formulas, statutory penalty amounts for overcharging, or universal startup discounts.

Also avoid using compensation to do work that belongs to another rule. Trade secret risk should be handled through safeguards and, where justified, the Data Act handbrake. Bargaining-power problems should be handled through unfair-term review. Personal data issues still need GDPR compliance, because the Data Act does not create a new legal basis for personal data processing.

  • Do not publish a fee schedule unless each amount can be tied to Article 9 inputs and recipient category.
  • Do not charge protected SMEs or not-for-profit research organisations more than the making-available cost cap.
  • Do not use compensation clauses to hide refusal, delay, discrimination, trade secret overreach, or unfair take-it-or-leave-it terms.

What Data Act source evidence should teams keep for the Compensation For B2B Data Sharing FAQ decision?

Keep the source material that shows why this Data Act FAQ answer is grounded in Article 9 and related Commission guidance. For a compensation question, the most useful evidence is the exact legal trigger, the cost basis used, the recipient type, and any transparency note that was shared with the recipient.

Also keep the version of the source you relied on, because the current answer depends on the Data Act text, the Commission explanation page, and the FAQ guidance on compensation, margin limits, and disclosure. If the calculation later changes, reviewers should be able to see what changed and why.

  • Save the Article 9 citation, the recipient classification, and the calculation basis used in the answer.
  • Store the Commission source URLs and the specific guidance point each one supports.
  • Keep the disclosure text sent to the recipient, not just the internal worksheet.

How should teams assign ownership for Data Act Compensation For B2B Data Sharing implementation work?

Assign the Data Act question to the team that can actually change the compensation workflow. In practice, that is usually legal for the Article 9 analysis, finance or pricing for the worksheet, and the product or operations owner for the request process and recipient notice.

One person should own the final decision, but legal, commercial, privacy, and security reviewers should each have a clear role. That helps avoid a single compensation amount being reused in situations that have different recipient categories, different cost bases, or different trade secret constraints.

  • Name one owner for the Article 9 decision, one owner for the worksheet, and one owner for the recipient notice.
  • Record which team checks SME or research-organisation status before any cap is applied.
  • Keep legal, finance, and operations responsibilities separate so the same template is not used for every request.

Which Data Act implementation evidence makes the Compensation For B2B Data Sharing answer usable later?

The Data Act answer is only useful later if someone can trace it back to the actual request, the data scope, and the cost model. Keep the request or contract clause that triggered Chapter III, the internal calculation, the recipient-facing explanation, and any note showing whether the cap for SMEs or not-for-profit research organisations was applied.

It also helps to keep evidence of any trade secret safeguards, because those often affect the amount and the wording of the disclosure. If the issue is ever challenged, the reviewer should be able to reconstruct both the amount and the reason the amount was disclosed in that form.

  • Keep the request, the Article 9 worksheet, and the recipient-facing calculation basis together.
  • Store the status check for SME or not-for-profit research organisation treatment.
  • Retain the trade secret safeguard note and the final notice language so later reviewers can see the full context.
