As stablecoin adoption accelerates globally, more institutions are exploring the launch of their own tokens. However, they quickly run into several dilemmas. One of the key questions is always which blockchain to choose. According to Maghnus Mareneck, co-CEO of Interchain Labs, an increasing number of companies will opt to create their own chain.
In this environment, interoperability is everything, Mareneck explains, pointing to the recent example in Japan. With $1.3 billion in stablecoins issued in the first half of 2025, there is growing awareness of their use cases. Notably, on August 22, SMBC Group, one of Japan’s largest banks, partnered with several blockchain firms to use stablecoins in payments for security tokens.
“Stablecoins are one of the most impactful use cases for crypto, and companies are aware of it” said Mareneck. “We are getting panicked calls from company executives that ask us what is this going to do to their business, and how can they get ahead of it,” he added.
The new system will cut fees and increase the speed of settlement. At the same time, the programmable nature of blockchain eliminates counterparty risk. Critically, the partnership will leverage the IBC protocol and the Cosmos (ATOM) stack to enable interoperability between multiple blockchains.
