Digital Token Identifier Foundation (DTIF)

The Digital Token Identifier Foundation (DTIF) is the non-profit Registration Authority for ISO 24165, the international standard that assigns a unique, machine-readable identifier to every fungible digital token built on a distributed ledger. Established in August 2021 as a non-profit division of Etrading Software, DTIF administers the Digital Token Identifier (DTI) system the same way legacy financial markets rely on ISINs for equities or LEIs for legal entities: as a shared, neutral identifier that every participant in a market can use without re-interpreting proprietary codes.

The Problem DTI Solves

Before ISO 24165, the crypto industry used informal shorthand — ticker symbols like BTC, XBT, or wBTC — that were never designed for precision. As DTIF's Rowan Varrall noted, three-letter currency codes are "not fit for uniquely identifying hundreds or thousands of tokens." The structural complexity of the digital asset space compounds the problem. A wrapped token, a bridged asset, and a forked chain each create a new instrument with distinct technical and counterparty characteristics; over a dozen tokens currently carry the wBTC designation across different blockchains. Without a common identifier, the same asset name refers to instruments with different risks, and cross-venue aggregation, regulatory reporting, and risk management all degrade.

How the Digital Token Identifier Works

Each DTI is a random nine-character alphanumeric code assigned to a single fungible digital token on a specific distributed ledger. Randomness is deliberate: it prevents any issuer from inferring information about registry size or internal sequencing. Behind every code sits a standardized reference data record describing the token's technical attributes, the ledger it runs on, and its classification — cryptocurrency, stablecoin, e-money token, security token, utility token, or digital/virtual asset. The code and its associated record together form the DTI record.

Participants interact with the system through three channels: a public online registration form for one-at-a-time requests, a bulk allocation workflow for large portfolios, and a DTI API for programmatic integration. The full registry is publicly downloadable at no cost. The standard's second part, ISO 24165-2:2025, published in 2025, codified the complete set of data elements required for each registered token.

Regulatory Mandates and Adoption

The DTI's most significant growth driver has been regulatory mandate. The European Union's Markets in Crypto-Assets Regulation (MiCA) designates the DTI as the required crypto-asset identifier for key compliance workflows, including Article 15 record-keeping, transparency reporting, and white paper classification disclosures. ESMA has additionally proposed using DTIs alongside ISINs for DLT-based financial instruments under its MiFIR review. Canada's trade reporting requirements for crypto trading platforms require DTIs. In April 2026, DTIF formally responded to proposed U.S. stablecoin legislation under the GENIUS Act, arguing that adopting the DTI would align the U.S. framework with MiCA, Canada, and other major jurisdictions already using the identifier.

DTIF expanded the DTI's scope in 2024 and 2025 to cover crypto-derivative regulatory reporting across G20 jurisdictions, with rollouts in the UK, Australia, Singapore, and Japan. Separately, DTIF and ANNA (the Association of National Numbering Agencies) coordinated DTI and ISIN allocation so that DLT-based financial instruments can receive both codes through a streamlined process, with a new XT-prefixed ISIN class linking functionally fungible tokens that trade across multiple ledgers.

Real-world implementations include 21X — Europe's first licensed DLT trading and settlement system — which adopted the DTI for all tokens listed on its Frankfurt-based platform, covering both tokenized financial instruments and stablecoins. 21X CEO Max Heinzle cited regulatory clarity and transparency as primary motivations. 21 Analytics, the first Travel Rule protocol to implement the DTIF standard, integrated DTIs across more than 5,000 crypto assets by 2026. SDX (SIX Digital Exchange) is among other institutions that have adopted the standard.

Scale and Registry

As of September 2024, DTIF had issued DTIs for 2,554 commonly traded assets, with the registry growing continuously as new tokens are registered. By early 2026, independent integrators reported supporting more than 5,000 DTI-registered assets. The registry is available through a searchable web interface and as a bulk download, both free of charge and consistent with the standard's open-data principles.

Governance and Business Model

DTIF operates on a non-profit, cost-recovery basis, with all registration and registry access provided free of charge. The organization adheres to FRAND (fair, reasonable, and non-discriminatory) principles required by ISO governance. A Product Advisory Committee — including representatives from BNY Mellon, SWIFT, SIX, GLEIF, and ANNA among others — guides standard development and ensures the DTI remains aligned with market and regulatory needs. DTIF CEO Sassan Danesh has described growing DTI adoption as evidence of "recognition of DTI as a vital tool for enhancing transparency and regulatory oversight."

Solana Ecosystem Fit

The DTI standard is chain-agnostic by design. Each identifier links a token to its specific ledger, meaning Solana-based tokens — including native assets, SPL tokens, stablecoins, and tokenized instruments issued on Solana — are eligible for DTI registration under the same ISO 24165 framework as tokens on Ethereum, Bitcoin, or any other DLT. As regulators in the EU, Canada, and potentially the U.S. require DTIs for reporting and compliance, Solana projects issuing regulated instruments or operating in jurisdictions with MiCA-equivalent rules will encounter DTI requirements directly. DTIF's free registry and public API make integration practical at any scale.
