"The completion of this Avalanche integration represents a landmark moment where the Japanese security token market connects directly with the global real-world asset ecosystem." — Tatsuya Saito, CEO, Progmat Inc.
Progmat, Japan's dominant security-token platform, completed the migration of ¥452 billion ($2.8 billion) in tokenized real estate and corporate bonds from R3's Corda 5 distributed ledger to a dedicated Avalanche Layer 1 on July 10, 2026. The move, announced February 26 under the internal codename "Project Keystone," finished roughly ten days past its end-of-June target but caused zero operational disruption to issuers, according to the company.
The migration is the largest single relocation of regulated digital securities onto a public-chain-adjacent environment to date. It converts Progmat's entire smart-contract stack from Java-based Corda code to Solidity-based EVM contracts, unlocking native composability with the broader Ethereum ecosystem. Internal benchmarks show rights-transfer processing is now 3 to 5 times faster than the pre-migration environment, with transaction finality under two seconds.
The platform, founded by MUFG and backed by SMBC, Mizuho, Sumitomo Mitsui Trust, SBI, Japan Exchange Group (JPX), and NTT Data, controls roughly 63% of cumulative issuance volume and 53.8% of total projects in Japan's security-token market. Its next objective — tokenizing Japanese Government Bonds (JGBs) for same-day repo settlement — would bring on-chain infrastructure to a ¥240 trillion ($1.6 trillion) market.
Corda served Japan's early security-token market adequately. R3 reported more than 20 regulated finance networks running live on the platform as of 2025, with over $17 billion in tokenized assets. But Corda's permissioned architecture imposed three constraints that Progmat determined were incompatible with its growth trajectory:
Composability ceiling. Corda contracts are not EVM-compatible. Security tokens issued on Corda cannot natively interact with decentralized exchanges, stablecoin rails, or cross-chain liquidity protocols. This siloes Japanese digital securities from the $180 billion-plus global RWA tokenization market.
Developer ecosystem narrowing. Corda contracts are written in Java/Kotlin on a proprietary runtime. The Solidity/EVM developer pool dwarfs Corda's. Progmat's transition to EVM contracts gives it access to a broader tooling base and audit ecosystem.
Performance bottleneck. Progmat's internal testing measured a 3-5x speed improvement in rights-transfer processing after moving to the Avalanche L1 architecture. Transaction finality dropped from Corda's multi-second consensus rounds to sub-two-second finality on Avalanche.
CEO Tatsuya Saito framed the move as a shift toward "progressively permissionless" infrastructure: "We're moving Progmat ST from Corda5 to Avalanche, making all ST deals EVM-compatible and progressively permissionless."
The decision carries risk. A full-stack rewrite — Java to Solidity, Corda consensus to Avalanche's Snowman protocol, proprietary node architecture to AvaCloud-managed validators — is a non-trivial engineering operation. That every active project on the platform migrated without operational disruption, according to the company, is a notable execution claim. Independent verification of zero-downtime was not available at time of publication.
The migration introduced a "mediator" architecture that decouples Progmat's core business logic from the underlying blockchain layer. This abstraction is significant: it means Progmat is not permanently locked into Avalanche. If it needs to issue tokens on Ethereum, Solana, or a future chain, the mediator layer allows this without rewriting the platform.
Key technical specifications:
| Parameter | Pre-Migration (Corda 5) | Post-Migration (Avalanche L1) | |---|---|---| | Smart contract language | Java/Kotlin | Solidity (EVM) | | Consensus | Corda notary cluster | Snowman (Avalanche) | | Finality | Multi-second | Sub-2 seconds | | Rights transfer speed | Baseline | 3-5x faster (internal benchmark) | | Infrastructure provider | Self-hosted Corda nodes | AvaCloud managed infrastructure | | Compliance certifications | N/A published | SOC 1, SOC 2 Type II | | Cross-chain capability | None | Native via Avalanche Interchain Messaging + LCP |
The AvaCloud-managed infrastructure includes a response system for outages during nights and holidays, a detail that underscores the institutional-grade SLA expectations of Progmat's bank-affiliated user base. The SOC 1 and SOC 2 Type II certifications are standard for financial services infrastructure but rare in blockchain deployments.
BOOSTRY, the market data provider operated by Nomura-affiliated entities, published its FY2025 market report in April 2026. The data shows a market that has doubled year-over-year but remains concentrated in a single asset class.
FY2025 issuance breakdown:
| Asset Type | Issuance (¥B) | Share | |---|---|---| | Real estate trust beneficiary securities | 140.8 | 85.3% | | Corporate bond security tokens | 20.4 | 12.4% | | Private equity trust beneficiary securities | 2.4 | 1.5% | | Real estate silent partnership equity | 1.4 | 0.8% | | Total | 165.0 | 100% |
Cumulative issuance through March 31, 2026, reached ¥333.3 billion across 82 tokens. Seven individual deals exceeded ¥10 billion. The secondary market, ODX's START platform, listed 8 tokens with ¥33.6 billion in capitalization.
FY2026 projections: BOOSTRY forecasts ¥200 billion in new issuance, bringing the cumulative total to ¥530 billion. Some earlier projections from the Datachain partnership announcement cited ¥1.053 trillion by end of 2026. The discrepancy is material and likely reflects differing methodologies — BOOSTRY counts publicly disclosed deals, while the broader figure may include private placements and cross-border issuance.
Progmat's share of this market: 45 of 89 public security-token projects (53.4% of deals) and 64.6% of total issuance value. The platform's dominance is structurally reinforced by its ownership — MUFG (42%), SMBC (~6.5%), Mizuho (~6.5%), Sumitomo Mitsui Trust (~6.5%), with additional stakes held by SBI, JPX, and NTT Data. Japan's three megabanks effectively own the tokenization infrastructure they distribute through.
On May 8, 2026, Progmat launched a 40-institution working group to study tokenizing Japanese Government Bonds for on-chain repo settlement. The participant list reads like a directory of Japanese institutional finance:
The target: compress Japan's ¥240 trillion ($1.6 trillion) JGB repo market from T+1 to T+0 settlement via atomic delivery-versus-payment (DvP) on-chain. The working group will publish its findings in October 2026 and aims for commercial launch before year-end.
Three options remain under consideration for the cash leg:
If the working group selects a stablecoin cash leg, this would represent the first sovereign repo market to commit to stablecoin-based settlement. The implication for stablecoin demand — in yen or dollars — is substantial. Japan's JGB repo market averages roughly ¥100 trillion in daily turnover.
Datachain, a Tokyo-based interoperability firm, is the third pillar of the partnership announced February 26. Its role is to enable Progmat-issued security tokens to settle across blockchains beyond Avalanche.
The technical mechanism uses Datachain's LCP (Light Client Proxy) protocol, which provides verifiable cross-chain message authentication without relying on a centralized bridge operator. The protocol supports two settlement modes:
This is where the Progmat migration moves from a Japan-specific infrastructure upgrade to a potential node in the global tokenized-securities network. If Progmat-issued JGBs can settle atomically against USDC on Ethereum or BUIDL on Solana, the composability implications extend well beyond Japanese capital markets.
Timeline for cross-chain services is unspecified beyond "individual commercial deployment releases." No live cross-chain settlement has been demonstrated on the production system as of publication date.
The Progmat deal cements Avalanche's strategy of competing for institutional infrastructure rather than retail DeFi volume. Key institutional deployments on Avalanche as of Q2 2026:
Nick Mussallem, AvaCloud CEO, stated that executing a full migration of regulated securities without operational disruption "sets a new benchmark for institutional blockchain infrastructure."
Avalanche's Q1 2026 data, per Nansen, showed continued institutional adoption as the primary growth vector. The L1-per-institution model — where each deployer gets a sovereign chain with native interoperability to the broader Avalanche network — sidesteps the gas-fee volatility and shared-blockspace congestion that make Ethereum L1 unsuitable for regulated financial products with predictable cost requirements.
The Progmat migration restructures how economic value flows through Japan's security-token stack.
Under Corda: Value accrued to R3 (license fees), self-hosted node operators (internal bank IT), and Progmat (platform fees). The value chain was closed and opaque. No on-chain fee revenue was generated because Corda is not a public blockchain.
Under Avalanche L1: Value now distributes across AvaCloud (infrastructure fees), Avalanche validators (transaction fees, though minimal on a dedicated L1), Datachain (cross-chain settlement fees, when operational), and Progmat (platform fees). The shift creates a partially observable on-chain fee layer where it previously did not exist.
The SOC 1/SOC 2 compliance layer adds a cost that does not exist in permissionless DeFi deployments. This cost is the price of institutional access — regulated entities will not deploy on infrastructure that cannot produce audit reports.
Whether this value redistribution benefits end investors — the holders of tokenized real estate and corporate bonds — depends on whether the 3-5x speed improvement and cross-chain composability translate into tighter spreads and broader distribution. That remains unproven.
Progmat's migration is not an experiment. It is the relocation of a production financial system — one that processes the majority of Japan's security-token volume — from a private ledger to public-chain-adjacent infrastructure. The ¥452 billion already migrated dwarfs most RWA tokenization deployments globally.
The more consequential development is the JGB repo working group. If 40 institutions, including BlackRock and Japan's three megabanks, determine that sovereign bond repos can settle on-chain with stablecoin cash legs, the addressable market moves from ¥333 billion in cumulative security-token issuance to ¥240 trillion in daily repo turnover. That is a three-order-of-magnitude expansion in scope.
The technical infrastructure is in place. The regulatory framework — Japan's revised Financial Instruments and Exchange Act and Payment Services Act — is permissive relative to other G7 jurisdictions. The question is execution: whether atomic DvP across chains works at institutional scale, whether the stablecoin cash leg achieves regulatory approval, and whether the October 2026 working group report produces actionable specifications or another study.
Japan's capital markets are moving on-chain. The pace is measured in billions of yen, not billions of dollars. But the direction is unambiguous.
