Japan’s $6.5B Stablecoin Push: How Cosmos Powers 200 Banks in Tokenized Deposit Revolution

TLDR:

  • Progmat Coin consortium unites 200+ Japanese banks for ¥1 trillion three-year stablecoin issuance plan.
  • Project Pax integrates Swift API with IBC protocol to preserve banking workflows while modernizing settlement.
  • Cosmos architecture enables ledger-level compliance controls and permissioned issuance for regulated assets.
  • IBC interoperability protocol maintains zero security exploits since 2021 launch across 200+ blockchains.

 

Tokenized deposits and stablecoins continue to reshape institutional settlement systems as major financial players adopt blockchain infrastructure.

Japan’s banking consortium, backed by over 200 institutions, plans to issue approximately ¥1 trillion in stablecoins over three years using Cosmos technology.

The initiative demonstrates how traditional finance integrates programmable money while maintaining regulatory compliance and operational control.

Banking Consortium Leverages Cosmos for Cross-Border Settlement

Progmat Coin represents a significant development in institutional blockchain adoption. The platform, co-developed by Datachain, brings together Japan’s largest banks and financial institutions. The consortium selected Cosmos infrastructure to address persistent inefficiencies in cross-border payments.

Project Pax, launched by Progmat and Datachain, uses the Inter-Blockchain Communication Protocol as its core interoperability layer.

The architecture preserves existing banking workflows while modernizing settlement infrastructure. Banks initiate payments through Swift’s API, maintaining familiar compliance controls throughout the process.

The settlement layer operates across both public and private blockchains. Progmat issues regulated stablecoins that move via IBC connections. Datachain’s multi-prover security model meets Japanese regulatory requirements while enabling cross-chain transfers.

This design targets the G20’s identified weaknesses in cross-border payments. The system eliminates correspondent banking chains and enables real-time settlement.

It decouples payment reach from correspondent relationships and provides immutable records for regulatory reporting.

Compliance Controls and Network Connectivity Drive Institutional Adoption

Cosmos-based chains allow institutions to embed compliance logic at the ledger level. Issuers configure permissioned issuance, whitelisted participants, and transaction limits directly into chain architecture. This approach shifts enforcement closer to the point of issuance rather than relying on external controls.

The technology stack powers over 200 independent blockchains. The interoperability protocol has remained free of security exploits since launching in 2021.

This track record addresses threshold concerns about whether underlying technology can operate at scale.

Institutions retain control over validator selection and governance processes. Compliance logic, redemption workflows, and access controls embed at the ledger level.

Issuers can restrict IBC connections to approved counterparty chains that implement compatible compliance standards.

Cosmos supports EVM compatibility through its framework, enabling interaction with existing treasury and payment applications.

Institutions can restrict connectivity to approved networks while maintaining access to broader liquidity ecosystems.

This connectivity allows tokenized deposits to operate within purpose-built chains without sacrificing interoperability.

The Progmat initiative illustrates how regulated stablecoin infrastructure can scale while preserving predictability. Financial institutions require control, compliance, and integration with existing banking systems.

Tokenized deposits extend bank money into programmable environments without replacing central bank-issued currencies or disrupting core banking operations.

Ethereum Dust Attacks Have Increased Post-Fusaka

Ethereum Dust Attacks Have Increased Post-Fusaka

Stablecoin-fueled dusting attacks are now estimated to make up 11% of all Ethereum transactions and 26% of active addresses on an average day, after the Fusaka upgrade made transactions cheaper, according to Coin Metrics. 

Ethereum is now seeing more than 2 million average daily transactions, spiking to almost 2.9 million in mid-January, along with 1.4 million daily active addresses — a 60% increase over prior averages.

The Fusaka upgrade in December made using the network cheaper and easier by improving onchain data handling, reducing the cost of posting information from layer-2 networks back to Ethereum.

Digging through the dust on Ethereum

Coin Metrics said it analyzed over 227 million balance updates for USDC (USDC) and USDt (USDT) on Ethereum from November 2025 through January 2026.

It found that 43% were involved in transfers of less than $1 and 38% were under a single penny — “amounts with insignificant economic purpose other than wallet seeding.”

“The number of addresses holding small ‘dust’ balances, greater than zero but less than 1 native unit, has grown sharply, consistent with millions of wallets receiving tiny poisoning deposits.”

Pre-Fusaka, stablecoin dust accounted for roughly 3 to 5% of Ethereum transactions and 15 to 20% of active addresses, it said. 

“Post-Fusaka, these figures jumped to 10-15% of transactions and 25-35% of active addresses on a typical day, a 2-3x increase.”

However, the remaining 57% of balance updates involved transfers above $1, “suggesting the majority of stablecoin activity remains organic,” Coin Metrics stated.

Users need to be wary of address poisoning

In January, security researcher Andrey Sergeenkov pointed to a 170% increase in new wallet addresses in the week starting Jan. 12, and also suggested it was linked to a wave of address poisoning attacks taking advantage of low gas fees

These “dusting” attacks typically involve malicious actors sending fractions of a cent worth of a stablecoin from wallet addresses that resemble legitimate ones, duping users into copying the wrong address when making a transaction.

Sergeenkov said $740,000 had already been lost to address poisoning attacks. The top attacker sent nearly 3 million dust transfers for just $5,175 in stablecoin costs, according to Coin Metrics.

Dust does not represent genuine economic usage

Coin Metrics reported that approximately 250,000 to 350,000 daily Ethereum addresses are involved in stablecoin dust activity, but the majority of network growth has been genuine.  

“The majority of post-Fusaka growth reflects genuine usage, though dust activity is a factor worth noting when interpreting headline metrics.”
