Stablecoins: Beyond the Hype

On Thursday, 18th September, I had the distinct pleasure of moderating a timely and crucial panel discussion on a topic that sits at the very heart of Synaptic Finance: "Stablecoins and their Role in Traditional Finance." Hosted by Blockchain Ireland's Startups & Web3 working group at Hyde in Dublin, the event brought together a remarkable group of experts from across the spectrum of government, venture capital, decentralized finance, and core blockchain infrastructure.

As I've recently been appointed the lead of the Blockchain Ireland Web3 and Startups working group, this event was particularly significant. It represents exactly what I hope to foster: a vibrant, open forum for honest debate and knowledge sharing, connecting the builders, regulators, and investors who are shaping the future of Ireland's digital economy. I am incredibly excited to help drive this platform forward, creating more opportunities to bridge the gap between emerging technology and mainstream adoption.

The conversation on Thursday was a testament to the maturity of the digital asset space. We've moved beyond the abstract promises of "disruption" and are now grappling with the complex realities of regulation, integration, and real-world utility. With a panel featuring Mai Santamaria from the Department of Finance, Peter Oakes of Fintech Ireland, Michael O'Loughlin from Argonautic Ventures, Evan Slattery of Base (at Coinbase), and Founder and Chair of Blockchain Ireland, Lory Kehoe, also representing Aave Labs, the discussion was bound to be insightful. It did not disappoint.

Here are my key takeaways from a night of robust debate.

Part 1: Defining the Terms and Building Trust

The discussion began by tackling the foundational questions: what are we even talking about, and why should anyone trust it?

From the government's perspective, Mai Santamaria outlined the careful and considered approach the Irish Department of Finance is taking. The primary goal is to foster innovation while ensuring consumer protection and financial stability. The emergence of stablecoins is not seen as a threat, but as a new financial instrument that requires a clear and robust regulatory framework. The focus is on responsible integration, ensuring that as these digital dollars enter the mainstream, they adhere to the same high standards of transparency and security that underpin our traditional financial system. This reflects the broader European push with regulations like the Markets in Crypto-Assets (MiCA), which aims to create a harmonized and safe environment for digital assets across the EU.

Peter Oakes then demystified the concept for the audience, stripping away the jargon to define a stablecoin in simple terms: a digital token that aims to hold its value against a traditional currency, like the euro or the dollar. He stressed that public trust is not a given; it must be earned through rigorous oversight and transparent operations. He drew a critical distinction between the legal definitions of stablecoins in different jurisdictions, highlighting the nuance that often gets lost in mainstream discourse.

In the US, Peter noted, proposed legislation like the Clarity for Payment Stablecoins Act often defines a stablecoin as something that creates a "reasonable expectation" of maintaining a stable value. In contrast, the EU's MiCA regulation for an e-money token is much tighter, requiring that it "purports to maintain a stable value by referencing the value of one official currency." This subtle difference in legal language has massive implications for issuers and consumers. Peter also pointed out the EU's deep-seated concern about being outmaneuvered by US-dollar-denominated stablecoins, a fear born from the dominance of American card networks like Visa and Mastercard. This geopolitical tension, he argued, is a major driver behind the push for a Digital Euro, which risks becoming an instrument "forged from fear of irrelevance, isolation and loss of monetary & payments sovereignty," as stated in his presentation. For those interested in a deeper dive, Peter generously offered attendees access to his up-to-date slides on the topic at fintechireland.com.

Part 2: Real-World Impact Beyond the Hype

With the foundations laid, the conversation shifted to the most important question: what real-world problems are stablecoins actually solving today?

Evan Slattery, representing Base, the Layer 2 blockchain incubated by Coinbase, elaborated on this, stating that mass adoption will only happen if the on-chain experience is a more optimal infrastructure. He pointed to JP Morgan’s recent launch of a USD Deposit token on Base as a prime example, driven by the platform's sub-cent fees, sub-second transaction speeds, and 24/7 settlement capabilities. 'We have hit the point with on-chain technologies where it’s like inventing teleportation for the aviation industry,' he remarked. Evan also explained how Base is making this accessible globally by supporting local currency stablecoins, enabling apps like Transferos to offer direct transfers to local payment systems in Brazil, and Vifi to do the same in Kenya. This is being further scaled through tools like Base Pay, which has already brought simple USDC checkouts to over 200,000 Shopify stores, often with gas fees sponsored by developers to create a seamless user experience

Venture capitalist Michael O'Loughlin from Argonautic Ventures provided a sharp, pragmatic perspective, urging the audience to look beyond the hype and focus on utility. He shared compelling examples of bot-to-bot micropayments, practical cases where programmable money removes intermediaries and solves real problems in supply chain and IoT. Michael argued that while DeFi will undoubtedly create new use cases, we must first learn to use our existing technologies, like real-time payment systems, more efficiently, rather than blindly relying on privately-backed tokens.

He cautioned against the tribalism that often plagues the crypto space, urging the audience to "try before you buy" and make informed, research-driven decisions. In a powerful closing thought, he warned that blind loyalty to any single coin, created by humans and run by bots, risks drifting into cultish behavior. Progress, he stressed, is not a zero-sum game.

Lory Kehoe of Aave Labs broadened the aperture beyond simple payments. As a leader in the decentralized finance (DeFi) space, Aave leverages stablecoins as the fundamental building block for a new, parallel financial system. He explained that in the world of DeFi, stablecoins are not just for paying for things; they are the primary collateral for decentralized lending, the unit of account for complex derivatives, and the lifeblood of on-chain capital markets. This is where the true innovation lies: using stable, programmable dollars to create financial services that are more open, transparent, and accessible than their traditional counterparts.

Part 3: The Future Landscape - Coexistence or Competition?

The final part of our discussion looked to the future, exploring how this new world of digital money will evolve.

Mai Santamaria emphasized that for innovation to flourish safely, effective collaboration between the public and private sectors is essential. The government's role is not to pick winners, but to set clear rules of the road that allow innovative companies to build with confidence, knowing they are operating within a compliant framework.

From the DeFi perspective, Lory Kehoe discussed Aave's own decentralized stablecoin, GHO. He explained that the unique benefit of a decentralized, over-collateralized model is its resistance to censorship and its inherent transparency. He doesn't see it as a winner-take-all scenario, but rather a future where centrally-issued, fiat-backed stablecoins and decentralized stablecoins coexist, serving different use cases and risk appetites.

Evan Slattery brought the conversation back to the user experience. For stablecoins to achieve mass adoption, they need to be as fast, cheap, and easy to use as traditional digital payments. He explained that this is the core mission of Layer 2 solutions like Base: to provide the scalable, low-cost infrastructure that will allow developers to build applications that can serve millions of users without the high fees and slow transaction times of older blockchains.

Finally, Peter Oakes tackled the looming question of the Digital Euro and its relationship with private stablecoins. He reiterated that the ECB's primary motivation is monetary sovereignty. The fear is a future where the European economy runs on digital dollars issued by private, foreign companies. In this context, the Digital Euro is seen as a necessary defensive measure. However, this doesn't mean it's a case of one or the other. A well-designed Digital Euro could coexist with a thriving market of private, regulated stablecoins, each serving different functions within the broader financial ecosystem.

Final Thoughts

As we wrapped up, I asked each panelist for one final, one-sentence takeaway. The answers were a microcosm of the entire discussion: a blend of cautious optimism, pragmatic realism, and a clear-eyed focus on the need for both innovation and integrity.

The evening reinforced my own conviction that stablecoins are not a niche crypto-asset; they are a fundamental evolution in the plumbing of our financial system. The conversation in Dublin is a reflection of a global shift, as traditional finance and Web3 move from a posture of mutual suspicion to one of cautious, and increasingly enthusiastic, collaboration.

I left the event energized and more excited than ever about my new role with Blockchain Ireland. The depth and quality of the conversation are a testament to the incredible talent and potential within the Irish ecosystem. My goal is to continue fostering these essential dialogues, helping to build the bridges that will allow the next generation of financial innovation to flourish, both in Ireland and beyond.
