Controlled testing space (sandbox)

Law 7/2020, of 13 November, for the digital transformation of the financial systemOpens in new window, establishes a set of measures to foster financial innovation in Spain, including the creation of a controlled testing environment, known internationally as a sandbox.

This environment is a controlled and delimited space in which to test projects involving a technology-based financial innovation applicable to the financial system that must be safe for participants and where risks to the financial system and the participants have been dully mitigated or minimised.



The sandbox allows testing, with all the necessary guarantees and under the supervision of the supervisory authority, technology-based financial innovations, provided that they comply, in the opinion of the supervisory authority, with the access requirements set out in Law 7/2020.

The sandbox thus aims to ensure that financial authorities have adequate instruments to continue performing their functions optimally in the new digital context and to facilitate the innovation process in Spain.

In addition, care will be taken to ensure that participation in the sandbox does not impede the full guarantee of public policy objectives in three particularly sensitive areas: the protection of personal data, the protection of users of financial services and the prevention of money laundering and the financing of terrorism.

The requirements for access to the sandbox are laid down in Article 5 of Law 7/2020:

  • Projects must provide a technology-based innovation applicable in the financial system and must be sufficiently advanced to be tested.
  • Innovative projects must provide potential added value in at least one of the following aspects: a) Facilitating regulatory compliance; b) Entailing a benefit for users of financial services; c) Increasing the efficiency of entities or markets; or, d) Providing mechanisms to improve regulation or financial supervision work.
  • For the purposes of access to the regulatory sandbox, the supervisory authorities will take into consideration the impact that the project in question could have on the Spanish financial system.

The sandbox is coordinated by the General Secretariat of the Treasury and International Financing (SGTFI, from its initials in Spanish), who chairs the Coordination CommissionOpens in new window.

The Commission is composed of representatives of the supervisory authorities (Banco de España-BdE-, the National Securities Market Commission-CNMV- and the Directorate General for Insurance and Pension Funds-DGSFP) and of other authorities such as the Executive Service of the Commission for the Prevention of Money Laundering and Monetary Offences (Sepblac) or the Spanish Data Protection Agency (AEPD).

The sandbox consists of three main stages: access, testing and exit.

  • Access is requested by submitting an application to the SGTFI (see next section). The supervisory authorities carry out the evaluation of the project by means of a reasoned favourable or unfavourable report on the basis of the access requirements set out in Law 7/2020. The report is forwarded to the SGTFI, which publishes the list of provisionally admitted projects to the sandbox.
  • In order to start the testing phase, it is required that the sponsor or group of sponsors, along with the supervisory authorities, subscribe to a protocol specifying the rules and conditions of the tests. In the case of involving real participants in these tests, the sponsor must also gather the informed consents of such participants by obtaining "unique informational documents" and activate the guarantee and compensation schemes.
  • Regarding the exit regime, the law provides for the possibility of reducing the procedure times in the event that a license or authorisation is required for the subsequent exercise of the professional activity. This occurs when the competent authorities for granting such authorization deem that the information and knowledge acquired during the testing phase allow for a simplified analysis of compliance with the requirements established by current legislation. In the document with conclusions, possible regulatory barriers that hinder financial innovation may be identified.

Access to the sandbox or the performance of tests within a pilot project shall not under any circumstances entail the granting of authorisation to start the exercise of a reserved activity or for the regular provision of financial services on a professional basis.

The law foresees two annual cohorts to apply for access to the sandbox and that any sponsor, or group of sponsors, whether natural or legal persons, can apply to enter the sandbox. The deadlines for each cohort are published on the SGTFI website.

Interested parties must submit their application, within the term established, through the electronic office of the SGTFI, attaching a supporting report in accordance with the provisions of Article 6 of Law 7/2020.

The SGTFI has published a guide on how to access the sandbox, which can be found at this link:

The first call for applications ran from 12 January to 23 February 2021 and a total of 66 applications were received, of which around two thirds were initially assigned to Banco de España, alone or together with other supervisory authorities. Of the projects reviewed by Banco de España, 10 projects received a preliminary favourable evaluation, and 6 proceeded to testing, following the signature of the corresponding protocol.

The second call was open from 1 September to 13 October 2021 and a total of 13 applications were received. Of these requests, 8 were initially assigned to Banco de España and 1 was subject to a preliminary favourable evaluation by this institution.

The third call was opened from 1 March to 12 April 2022. Of the projects reviewed by Banco de España, 2 projects received a preliminary favourable evaluation.

The fourth call was opened from 1 September to 13 October 2022. Of the projects reviewed by Banco de España, 2 projects received a preliminary favourable evaluation. In one of them, this institution will act as an observer authority.

The fifth call for proposals took place from March 1st to April 12th, 2023. Out of the projects reviewed by this institution, 4 have received a favourable preliminary evaluation.

The deadline for submitting projects was open between September 1 and October 13, 2023

The seventh call for proposals took place from March 1 to April 15, 2024

The Banco de España drafts, in accordance with article 17.3 of Law 7/2020, a conclusions’ document assessing the development and the results of the tests of those projects that have completed them. Below, you can consult the documents with conclusions of the following projects:

Documents with conclusions 1st cohort

Documents with conclusions 2nd cohort

Documents with conclusions 3rd cohort

This list will be updated as soon as other projects complete the tests and their corresponding documents with conclusions are approved.
