A token recorded on a blockchain is not, by itself, a legally valid security in Spain. The record only produces legal effects when a licensed registrar keeps it. That registrar is the ERIR, and for any foreign issuer structuring a tokenized issue under Spanish law, it is the one counterparty the project cannot go live without (Law 6/2023, art. 8).
What an ERIR is
ERIR stands for entidad responsable de la inscripción y del registro: the entity responsible for the inscription and the register. Think of it as the digital notary of the securities register. When shares, bonds or fund units are represented on distributed ledger technology, the ERIR is the supervised entity that inscribes the issue and maintains the record of ownership with legal effect (Law 6/2023, art. 8; Royal Decree 814/2023).
The statute never uses the acronym; the market adopted it. The regime itself sits in article 8 of Law 6/2023 and is developed in Royal Decree 814/2023, which sets out how DLT-based securities registers must operate. If a document attributes the figure to a different decree, treat that document with caution.
Why Spanish law requires one
Blockchains make tokens technically transferable. Spanish law asks a different question: is the transfer legally effective against everyone, including courts and third parties? Only an inscribed register answers yes. Without an ERIR, a token that claims to represent a share or a bond is technically mobile and legally inert; it does not qualify as a validly represented negotiable security (Law 6/2023, art. 8).
The consequence for planning is direct. The ERIR contract is one of the deliverables every issue needs, alongside the issuance document, the offer-regime documentation and the marketing policy. The full sequence is described in how to issue a security token in Spain.
What the ERIR actually does
Four functions define the role:
- Inscribes each issue, together with the documentation that fixes its terms and conditions.
- Maintains the ownership register, the record of who holds what, with legal effect.
- Answers for the integrity and immutability of the annotations kept on the ledger.
- Keeps the information available to holders and to the supervisor on a continuous basis.
Practical criterion for an issuer: everything the ERIR must certify has to exist in your issuance documentation first. Weak documents make slow registrars.
What an ERIR is not
| Figure | Regime | Role, in one line |
|---|---|---|
| ERIR | Law 6/2023 and RD 814/2023, CNMV | Registrar that gives DLT-represented securities legal validity |
| CASP | MiCA (Regulation (EU) 2023/1114) | Crypto-asset services; security tokens are excluded by art. 2.4 |
| Investment firm (ESI/EAF) | MiFID II | Distribution, placing, advice and order handling |
| Software provider | Unregulated technology layer | Issuance and lifecycle tooling; no registry or investment services |
HokenFi sits in the last row: a technology platform, not a CNMV-authorised entity. The regulated steps of a project run through authorised partners, the ERIR among them (Regulation (EU) 2023/1114, art. 2.4).
The first authorised ERIR, and what it means for your calendar
The CNMV authorised the first ERIR in November 2024: URSUS-3 Capital, A.V. The figure is young and capacity is scarce, which makes ERIR onboarding the usual critical path of a Spanish tokenized issue. Check the CNMV registers for the current list before you plan, and open the conversation early.
For context beyond Spain: Germany answered the same question in 2021 with its Electronic Securities Act (eWpG), whose crypto securities registrar performs a role comparable to the ERIR under BaFin supervision.
When to engage the ERIR in your project
Before technical development, not after. The order that avoids rework is: token qualification, issuer vehicle, issuance document plus ERIR contract, then smart contract. A registrar engaged late will re-open decisions the code has already frozen, and every reopened decision costs weeks.
If you are still deciding whether Spain is your venue, start from the HokenFi English hub; fund managers should read tokenized funds in Spain first.
No ERIR, no legally valid Spanish security token; engaging the registrar early is the cheapest schedule insurance a project can buy. Run the 2-minute issuance assessment or request a proposal.
