Progmat moves Japan’s largest security-token platform onto public-chain rails

Japan’s tokenized-securities market has taken a meaningful step beyond pilot-stage experimentation. Progmat, the country’s largest digital asset issuance and management platform for security tokens, has completed the migration of all live digital securities on its platform to an Avalanche Layer 1 environment, covering more than ¥452 billion in outstanding value. The move is important not because another blockchain won an infrastructure mandate, but because a regulated platform that already sits at the center of Japan’s security-token market has shifted live assets from a private ledger architecture to a public-chain-compatible base without interrupting institutional operations.

The migration was confirmed through multiple first-party channels. Progmat’s July 13 update said the full transfer of digital securities exceeding ¥452 billion had been completed, while Avalanche’s July 10 post described the project as a finished migration rather than a future roadmap item. The Block separately reported that the transition was completed on schedule and without disruption for participating financial institutions. For an RWA market still full of proofs of concept, that operational detail is the headline: the underlying infrastructure changed while the market kept running.

Scale is what makes the move matter. Avalanche’s account of the project says Progmat handles 45 of Japan’s 89 publicly disclosed security-token projects, representing 53.4% of the market by number of deals and 64.6% by total issuance value. Its footprint spans the two main domestic asset classes in Japan’s security-token market, tokenized real estate and tokenized corporate bonds. Progmat itself is not a greenfield startup; the platform was originally developed within Mitsubishi UFJ Trust and Banking before being spun out, and it now operates with backing from a broader consortium of Japanese financial institutions and market infrastructure groups.

Technically, the migration was more than a chain swap. According to Avalanche, Progmat redesigned its architecture so the platform is no longer tied to a single blockchain implementation, making future multi-chain expansion easier if market requirements change. Existing smart contracts were ported into an EVM environment without altering the behavior of live projects, and the firm says rights-transfer processing is now roughly three to five times faster than before. That combination matters for institutional tokenization: performance improvements are useful, but preserving the integrity of live legal and operational workflows is what makes migration credible in regulated markets.

The strategic significance is that Japan’s largest security-token stack is no longer confined to a domestic, permissioned environment that only local institutions can see. A public-chain-compatible foundation creates a clearer path toward interoperability with broader RWA infrastructure, cross-platform settlement design and shared standards around digital asset servicing. That does not mean the market instantly becomes open retail crypto. The assets remain governed by Japanese financial rules, issuer requirements and institutional controls. But the settlement and tokenization layer is moving closer to the global architecture that increasingly defines cross-border digital capital markets.

Progmat’s own roadmap shows why the migration is bigger than a completed infrastructure project. In a May 8 press release, the company launched a Tokenized JGB and On-Chain Repo Working Group to study how rights to Japanese government bonds could be tokenized and how repo transactions could be conducted onchain using tokenized collateral and stablecoin cash legs. The group plans to publish a report in October and pursue commercialization work this year. Avalanche said that effort is focused on features conventional bond-market plumbing cannot easily offer today, including around-the-clock trading windows and same-day settlement. In other words, the newly migrated platform is already being positioned as the base layer for sovereign-bond and repo use cases, not only for today’s real-estate and corporate-bond tokenization flows.

For RWA markets, that makes Progmat’s migration one of the stronger recent signals from Asia. A lot of tokenization headlines still describe partnerships, memoranda or sandbox intentions. This one describes a live market structure change affecting hundreds of billions of yen in issued securities, executed without downtime, and immediately connected to the next policy and product question: whether government bond financing activity can move onchain in commercial form. If that next step progresses, Japan will not just be experimenting with tokenization. It will be showing how an incumbent capital-markets platform can move real issuance, settlement design and collateral workflows onto public-chain rails in production.
