Horizen Labs Partners with Oraclizer to Advance Regulatory Compliance Standards for Tokenized…

Joint work includes the release of the draft EIP-RCP, an informational framework for cross-chain, cross-jurisdiction compliance interoperability.

Horizen Labs is collaborating with Oraclizer to help accelerate the next phase of tokenized capital markets: interoperable, regulatory-compliant assets that can move across chains and jurisdictions without breaking the user experience.

As part of this collaboration, Oraclizer and Horizen Labs have officially released the draft EIP-RCP (Regulatory Compliance Protocol for Tokenized Assets), an Informational Ethereum Improvement Proposal designed to define a shared compliance framework for tokenized assets in the Ethereum ecosystem.

The proposal is co-authored by Rob Viglione, CEO of Horizen Labs, and Daniel Spuller, Executive Vice President of Industry Affairs at the Blockchain Association, alongside the Oraclizer team.

The Issue We’re Working to Solve

Tokenized assets don’t just face technical fragmentation; they face compliance fragmentation.

Today, an asset issued under one standard or jurisdiction often can’t “meaningfully” interoperate with another without bespoke legal + technical mapping each time.

EIP-RCP is meant to be a common reference point: a structured way to describe what compliance requirements exist, how they differ, and what a token standard must support to be considered “complete enough” for regulated markets.

What EIP-RCP provides

The draft proposal consolidates 31 core requirements derived from a review of guidance from 15 global financial regulatory authorities, and organizes them under five principles:

1. Traceability
2. Privacy
3. Enforceability
4. Finality
5. Tokenizability.

It also introduces a shared vocabulary and a framework for understanding compliance actions that are often oversimplified in existing token standards. For example, current approaches frequently treat “controller transfer” as a catch-all, but seize vs. confiscate are legally distinct actions with different implications, and they should be represented distinctly onchain.

“The tokenized capital market won’t scale through fragmented compliance — it needs composable compliance. EIP-RCP gives the industry a shared vocabulary for compliance status and a standardized taxonomy for regulatory actions. Once compliance speaks the same language everywhere, the pool of truly interoperable assets explodes. At Oraclizer, we’re building an oracle state machine that synchronizes asset states between traditional finance and DeFi. For that bridge to function, compliance isn’t optional — it’s the prerequisite for it to exist at all.”

— Jonghun Hong, Team Lead of Oraclizer

Measuring Gaps in Today’s Standards

To make this practical, the proposal includes a Requirements Coverage Matrix showing how existing standards (including ERC-20, ERC-777, ERC-1400, and ERC-3643) cover (or fail to cover) the requirements, highlighting where the ecosystem is still thin, especially across monitoring, audit support, privacy requirements, and enforcement differentiation.

Horizen Lab’s Role and Contribution

Horizen Labs is supporting Oraclizer as both a strategic partner and contributing research and technical review. Together with Oraclizer’s team, and with policy co-authorship from Daniel Spuller (EVP of Industry Affairs, Blockchain Association), this draft is an initial step toward moving regulatory compliance from bespoke implementations to a shared, interoperable standard.

This work aligns with Horizen Labs’ long-term focus: bringing privacy, security, and real-world usability together, especially in environments where regulated actors need confidentiality and auditability.

“Horizen Labs has always cared about building systems that are both usable and accountable. This work with Oraclizer supports a future where regulated actors can use onchain rails with the right mix of confidentiality, auditability, and enforceability. Right now, ‘compliant tokenization’ is mostly bespoke plumbing. EIP-RCP helps turn it into a common framework with clear requirements and clearer distinctions, so regulated assets can actually interoperate instead of living in isolated silos.”
