Whisper, the Web3 super app developed by EQBR Holdings Co., Ltd., has announced it will unveil a new ecosystem built around the app at Korea Blockchain Week (KBW) in Seoul.

Paulus J. Lee, Founder of Whisper and Chairman of EQBR Holdings, will present the keynote on 4:40pm on September 30^th at Grand WalkerHill in Seoul, where the team will show what it has been building beyond the app itself.

Whisper brings everyday digital activity into one place. Its features include:

• Secure messaging: end-to-end encrypted, with private-key-based messages.
• Digital wallet: support for more than 10 blockchains and more than 100 assets.
• Swap exchange: instant token swaps, compatible with the Ethereum Virtual Machine (EVM).
• dApp Store: a curated way to browse DeFi, NFT, GameFi and SocialFi applications.
• Feed: curated Web3 news and project alerts.

The app has recorded 1.38 million cumulative downloads. The team has also tested the technology in real-world use, providing real-time, fully on-chain peer-to-peer payments at the Jeju Food & Wine Festival in 2023, 2024, and 2025, in partnership with Jeju Bank, a local commercial bank. In 2023-2025, the payment system operated across more than 200 restaurants at the festival, alongside the purchase and redemption of digital gift vouchers. A separate demonstration showed the underlying technology running on a Raspberry Pi, illustrating its ability to run on low-power devices.

Whisper is built on blockchain technology protected by U.S. Patent No. 12,586,064 B2, granted in March 2026. The patented system uses a non-competitive consensus method and a micro-chain architecture that lets different services run independently, so that heavy activity in one application does not slow the others. In testing, the approach achieved confirmation times of three seconds and throughput of up to about 4,500 transactions per second on a single micro-chain.

“Most people don’t want to learn about blockchain. They want to message a friend, pay a merchant, and swap a token in one place, quickly and securely,” said Lee. “We built Whisper so those everyday actions work smoothly on-chain, without the user having to think about the chain.”

“At Korea Blockchain Week, we’ll show the next step for Whisper: a new ecosystem built around the app,” Lee added. “We look forward to sharing it with the community in Seoul.”

Lee has more than three decades of experience as a founding father of games and digital content in Korea, including producing Electronic Arts’ Tiger Woods Golf 2000, and holds a master’s degree in materials science from KAIST (Korea Advanced Institute of Science and Technology).
