Written Interview Summary

Question: To start, could you introduce Stable and explain the problem you’re solving within the stablecoin ecosystem?
‍
Answer: Stable is a Layer 1 blockchain protocol focused on rebuilding the payment rails that move money on the internet. The problem we saw is that the systems used for payments today, both local and cross-border, were built in the 1970s and haven’t kept pace with the speed of the internet. Stable is creating infrastructure that enables sub-second finality and real-time stablecoin payments between individuals and institutions.
‍

Question: What are some of the biggest trends you’re seeing right now in the stablecoin sector?
‍
Answer: We’re seeing governments and major institutions start to embrace stablecoins as essential tools for economic growth. Faster settlement means faster commerce, which drives GDP. The U.S. regulatory movement, such as the Genius Act, has encouraged companies to innovate. We’ve also seen examples like Tether’s USAT launch, signaling how traditional financial players are becoming comfortable with stablecoins thanks to clearer regulation.
‍

Question: There’s been a lot of conversation lately about “stablecoin-specific blockchains.” How do those differ from general-purpose chains like Ethereum or Solana?
‍
Answer: Traditional Layer 1s were built to host anything, from games to NFTs, but that created congestion and unpredictable transaction fees. Payment use cases can’t afford that variability. Stablecoin-specific chains are purpose-built for payments, offering consistent performance and cost. At Stable, we’re focused on maintaining real-time settlement and predictable pricing, ensuring commerce happens smoothly even at scale.
‍

Question: And how does Stable’s approach differ from other projects working on similar ideas?
‍
Answer: We focus on three pillars. First, users. We’ve eliminated gas fees for peer-to-peer transfers, so users can send stablecoins instantly and for free. Second, enterprises. We introduced Guaranteed Block Space, letting institutions reserve transaction space and lock in predictable fees over time. Third, developers. Stable is EVM-compatible and integrated with LayerZero, so builders can deploy from day one using familiar tools.
‍

Question: You mentioned existing payment rails earlier. What lessons from traditional systems have influenced Stable’s design?
‍
Answer: The biggest issue is misaligned incentives. Merchants pay high fees, up to 3.5 percent, to accept cards, and banks profit from settlement delays. Systems like SWIFT and ACH are slow, closed, and fragmented, especially across borders. Stable fixes this by creating a unified, open network where funds move instantly, with minimal fees and no intermediaries taking cuts.
‍

Question: What recent developments in the financial space have you found most exciting?
‍
Answer: The fact that century-old institutions are integrating blockchain into their core settlement systems. That’s a huge validation. They’ve tested it, vetted it, and realized it works. It shows blockchain isn’t a passing trend, it’s becoming the infrastructure layer for global finance.
‍

Question: What are some common misconceptions about stablecoin-specific chains, and how is Stable addressing them?
‍
Answer: One misconception is that every new chain needs its own stablecoin. We’re taking the opposite approach. Our native gas token is USDT, so users don’t need to buy volatile tokens to transact. This removes a big friction point. We’re also collaborating with PayPal to support PYUSD from day one, enabling seamless, fee-free transfers. It’s all about reducing complexity and volatility in how people move money.
‍

Question: What’s your boldest prediction for stablecoins over the next two to three years?
‍
Answer: Adoption will outpace everyone’s expectations. The market is already near 300 billion AUM, and I think growth will accelerate as usability improves. The key is removing complexity. With Stable Pay, our upcoming non-custodial wallet built with Dynamic, users can send and receive stablecoins as easily as sending a message, with no private key confusion or gas tokens. That’s what will unlock true mass adoption.
‍

Question: Assuming the market reaches the projected multi-trillion-dollar level by 2030, what role do you see Stable playing in that growth?
‍
Answer: Our goal is to drive utility, not just total value locked. We want to see more transactions, more wallets, and more everyday use, not just assets sitting idle. Stablecoin adoption will rise as people start using them for payments, yield, and savings. For example, through our collaboration with Morpho, users can earn yield directly in their Stable wallets without complex staking steps. That kind of accessibility will transform the user experience and help stablecoins scale to trillions in circulation. We’re building toward a world where moving money is instant, transparent, and open to everyone. Stable is proud to play a part in making that possible.
