The gathering was the latest step in Cosmos Labs' broader pivot toward enterprise and institutional clients, a direction the organisation announced formally at its Cosmoverse conference in Split, Croatia, just weeks earlier. Cosmos Labs was formed in 2025 after the Interchain Foundation acquired the Skip protocol team.

Cosmos Labs co-CEO Maghnus Mareneck, who leads the company alongside co-CEO Barry Plunkett, framed the Buenos Aires event around a single directional claim: that sovereign, country-level blockchains will eventually become standard infrastructure, and that they will all connect to each other through IBC (the Inter-Blockchain Communication protocol, a system that lets separate blockchains transfer data and assets directly without relying on third-party intermediaries).

"We think that at some point in the future, every country will have its own blockchain. And all of those blockchains are going to be interconnected," Mareneck told attendees. He also pushed back against technology-first framing, noting that institutions "are focused on impact and revenue or savings a solution creates; only then concerned with technology."

Stablecoins as the Entry Point

A recurring theme at the event was that stablecoins (digital tokens pegged to a fiat currency, typically the US dollar) represent the most practical first step for banks and governments exploring blockchain. Michael Kirchner of McKinsey presented data showing that 7% of Fortune 500 companies currently use stablecoins, with 29% planning to adopt them by 2026. Separate industry data illustrated the broader scale of the shift: global stablecoin payment volume reached $390 billion in 2025, more than doubling from the prior year, with business-to-business transaction volumes up 733% year-over-year. Asia-Pacific alone accounted for $245 billion, or roughly 60% of that total. The scale of that regional figure signals why institutions across emerging markets are tracking stablecoin infrastructure with increasing urgency.

The event's choice of Buenos Aires was not incidental. Argentina's history of currency instability has produced one of the region's most stablecoin-active populations, and the presence of the Argentinian Chamber of Fintech signalled that local institutions are actively engaging with blockchain payment infrastructure rather than monitoring it from a distance.

Japan was held up as a regulatory model worth replicating. Andy Hung of Pacific Meta pointed to Tokyo's formalised stablecoin issuance rules and noted two concrete deployments on Cosmos infrastructure: Toki Finance's Project Trinity, backed by Sumitomo Mitsui Banking Corporation (SMBC), and Progmat's Project Pax, an MUFG-backed (Mitsubishi UFJ Financial Group) project integrated with SWIFT.

Separately, Cosmos Labs and infrastructure firm Peersyst confirmed that two central bank digital currencies (CBDCs) will launch on the Cosmos stack, following an announcement at Cosmoverse 2025. The issuing countries were not publicly named at the time of the event.

The attendance of Ondo Finance, which has facilitated more than $16 billion in tokenized real-world assets through Cosmos-compatible infrastructure, reflected the deepening interest of traditional finance players in on-chain asset issuance and added further institutional weight to the gathering.

The Technical Infrastructure Behind the Pitch

The enterprise case Cosmos is making rests on real protocol changes, not just positioning. In April 2025, Interchain Labs launched IBC Eureka (also called IBC v2), which established a direct connection between Cosmos chains and Ethereum using zero-knowledge cryptographic proofs powered by Succinct Labs' SP1 Prover network.

That matters for institutional adoption because it removes the need for third-party bridges, which have historically been a major security vulnerability in crypto infrastructure. Early adopting chains include Babylon Genesis, Injective, dYdX, and MANTRA.

The Cosmos SDK now supports Proof of Authority networks, a configuration that allows governments or regulated financial institutions to control who participates in validating transactions, a feature conventional public blockchains do not offer. An Enterprise Blockchain Fleet Manager is expected in 2026 to further reduce the technical overhead of launching a sovereign chain.

On-chain metrics support the growth narrative. IBC now connects more than 150 chains, up from roughly 100 at the end of 2024, processing over $3 billion in monthly transaction volume across 115 of those chains. Total ATOM staked hit an all-time high of 274 million tokens in H1 2025, a 15.7% increase, with a staking yield of 16.34%. Readers evaluating these figures should note that enterprise adoption of the Cosmos SDK does not automatically translate to ATOM value accrual. This structural gap is a known issue within the ecosystem, and a redesign of ATOM tokenomics remains ongoing with no confirmed timeline.

The Gap No One Addressed

For all the talk of sovereign national blockchains, the Sovereign Series has yet to hold an event in the two regions where the infrastructure need is arguably most acute.

No African or South Asian institution appeared on the participant list in Buenos Aires. Sub-Saharan Africa sees roughly $25 billion in monthly crypto transaction volume as of early 2025, driven largely by remittances and dollar hedging. Eleven African countries are actively exploring CBDCs, though Nigeria's eNaira remains the only fully live example on the continent. South Africa's central bank is expanding its Project Khokha CBDC pilot toward cross-border use cases that map directly onto what IBC is built to enable. Kenya, meanwhile, advanced its Virtual Asset Service Provider (VASP) Bill in 2025, a significant step toward formal regulatory engagement with digital assets and a marker of the growing builder and institutional community taking shape across East Africa.

India presents a similarly complicated picture. The RBI's retail digital rupee has crossed 120 million transactions, and the central bank has consistently advocated for CBDCs over stablecoins, including calling on other nations to follow suit. The Indian government is reportedly considering a stablecoin regulatory framework, creating a policy split that leaves institutional actors waiting for clarity before committing to any infrastructure. Compounding that uncertainty, India's Finance Act 2022 imposes a 30% flat tax on crypto gains, a concrete structural headwind for enterprise and retail adoption alike that no regulatory adjustment has yet addressed.

Cosmos Labs had not publicly announced dates or locations for future Sovereign Series events as of the time of publication, including any planned for Africa or South Asia.

Given that the protocol's core value proposition is cross-border interoperability at low cost, and that the most acute demand for exactly that infrastructure sits in Lagos, Nairobi, and Mumbai, the absence of a planned event in those markets is the most consequential question the series has yet to answer.
