Cardano Makes Its Case as the Preferred Rail for Non-USD Stablecoins
IOG publishes a technical argument for building locally denominated stablecoins on Cardano, citing architectural advantages and on-chain governance as the blockchain targets issuers in Africa, South Asia, and beyond.
Blockchain research and development firm Input Output Global (IOG) published the second part of its non-USD stablecoin series on April 16, 2026, arguing that Cardano's technical design and governance structure make it a more suitable home for sovereign stablecoins than competing platforms. The piece, written by IOG's Maurício Magaldi, arrives as the global stablecoin market approaches $312 billion in total supply, with USD-denominated tokens accounting for roughly 97 to 99 percent of that figure.
The scale of that imbalance is not abstract. In Nigeria, users conducted $22 billion in stablecoin transactions between July 2023 and June 2024. Across Africa broadly, 79 percent of crypto-active users hold stablecoins, the highest rate globally, yet the instruments they rely on are overwhelmingly USD-denominated, consistent with a global market in which dollar-pegged tokens represent 97 to 99 percent of total stablecoin supply. In the first part of the series, Magaldi argued that merchants in Berlin, Tokyo, or São Paulo who transact on-chain are effectively importing American monetary policy, inflation, and regulatory risk, which he characterized as a form of dollarization that forecloses genuine financial sovereignty.
The case for non-USD alternatives is equally compelling in South Asia. India ranked first globally in cryptocurrency adoption in 2025, according to TRM Labs, and received approximately $135 billion in remittances that year, making it the world's largest remittance recipient. Those flows represent a natural market for rupee-denominated instruments that settle on-chain without routing value through a dollar-pegged intermediary. Pakistan's large freelance workforce, which earns primarily in foreign currency and spends in Pakistani rupees, faces similar structural friction that a local-currency stablecoin could address.
What Cardano's Architecture Actually Offers
The technical centerpiece of IOG's argument is Cardano's extended UTXO model (eUTXO), which differs from the account-based architecture used by Ethereum and most EVM-compatible chains. On Cardano, tokens issued as Cardano Native Tokens are settled directly on the ledger rather than through smart contract code. That distinction matters because it removes entire categories of vulnerability. Reentrancy attacks and infinite approval exploits, both of which have cost hundreds of millions of dollars on other chains, simply do not apply to assets settled at the ledger level.
eUTXO also gives users cost predictability. A transaction's fee and outcome can be calculated before submission, not after. For a manufacturer in Brazil settling a trade invoice in a BRL stablecoin, that determinism has real operational value. Cardano also supports compliant freeze-and-seize functionality, a regulatory requirement for any licensed stablecoin issuer, without altering the underlying protocol.
Early infrastructure data supports the performance claims. When Circle's USDCx token launched on Cardano mainnet on February 27, 2026, more than 15 million tokens were minted and over 6,100 bridge transactions were processed in the first week. Organic bridging volume reached approximately $1.17 million. IOG's summary of that period was pointed: "Zero smart contract errors. No escalations to Circle. The infrastructure did exactly what it was designed to do."
Governance as an Infrastructure Argument
IOG's case is not purely technical. Magaldi frames Cardano's on-chain governance model as a competitive differentiator for sovereign or regulated stablecoin issuers who cannot rely on infrastructure controlled by entities with competing monetary interests.
"With most blockchain ecosystems either funded, owned, or powered by value-extracting capital, only a few chains can position themselves as credibly neutral infrastructure for sovereign monetary instruments," Magaldi writes. "Cardano is one of them."
The neutrality claim has institutional backing in the form of a ₳70 million treasury allocation ratified through Cardano's on-chain governance process in late 2025. The funding, channeled through the Critical Integrations Initiative (CCI) and managed by a consortium of Cardano entities called the Pentad, covers oracle integrations, stablecoin rails, custody infrastructure, and cross-chain bridges. Pyth Network oracle support was code-complete as of March 2026 and is targeting a Q2 launch.
That governance structure deserves scrutiny, though. The Pentad itself, which includes IOG, EMURGO, the Cardano Foundation, Intersect, and Midnight Foundation, retains substantial influence over the ecosystem's direction. Credible neutrality is a matter of degree, and Cardano's version should be evaluated relative to other chains rather than treated as absolute.
The Capital Flight Problem
The most consequential gap in IOG's argument concerns a tension that Tiger Research flagged in its 2026 Asia Stablecoin Market Overview. Once a local-currency stablecoin exists on a public blockchain alongside USD stablecoins, conversion between the two becomes trivially easy. That accessibility cuts both ways. The same infrastructure that lets a Pakistani resident hold and spend in PKR could also accelerate capital outflows during currency stress, as holders convert local-currency savings into dollar-pegged instruments. That is precisely the scenario central banks in India and Pakistan have publicly worried about. IOG's article does not address this dynamic directly.
The Numbers on the Ground
Cardano's DeFi total value locked reached 552 million ADA, approximately $140.83 million, in March 2026, up 23 percent over a 12-day stretch following the stablecoin supply surge. Total stablecoin supply on Cardano stood at about $47.7 million as of March 2026. USDCx accounts for roughly 37 percent of that, followed by USDM at $14.53 million, USDA at $8.65 million, and DJED at $3.67 million. Via LayerZero, Cardano now connects to more than 50 other blockchains, extending reach to potential issuers and users on Ethereum, Solana, and elsewhere.
The question IOG is raising is not whether non-USD stablecoins should exist; that argument is increasingly supported by the data. The question is whether Cardano's architecture, governance, and current DeFi stack can attract the issuers who would build them. The infrastructure is live and performing. No non-USD stablecoin issuers have yet publicly committed to building on Cardano.
