TheRadius.xyz – Gabia customer – (South Korea)
Projects advancing blockchain technology use .xyz domains to establish a clear and consistent digital identity. Blockchain startup Mamori.xyz applies machine learning to address vulnerabilities in the web3 ecosystem. Onchain trading firm Warlock.xyz develops systems for responsible order flow management in decentralized markets. Blockchain project Miden.xyz explores edge execution and private smart contracts using zero-knowledge technology. In this week’s #BlockchainThursday, we’ll introduce you to a company building infrastructure to help Ethereum rollups grow through MEV revenue and user-protective block building: TheRadius.xyz.
TheRadius.xyz is the online home of Radius, a South Korea-based blockchain infrastructure company focused on helping Ethereum Layer 2 (L2) networks capture sustainable revenue through Maximal Extractable Value (MEV). According to the website, Radius does this through two main offerings: Lighthouse, a decentralized network that connects searchers and rollups to unlock MEV revenue, and Secure Block Building (SBB), which enables MEV capture while aiming to protect users from harmful transaction manipulation. In January 2025, Radius announced a $7M seed round led by Pantera Capital.1
Rollups are a key component of Ethereum’s scalability roadmap, but according to Radius, many face challenges due to unstable transaction fee revenues. The Radius documentation describes how the platform addresses this issue by creating new infrastructure for MEV-based revenue that supports more sustainable L2 operations. The Lighthouse network connects rollups with MEV searchers, while Secure Block Building integrates safeguards against risks like frontrunning and sandwich attacks. The website highlights several participants in the Radius ecosystem, including rollup and infrastructure projects such as Hyveda.xyz, Caldera.xyz, and Karnot.xyz, which contribute to or build on the Radius protocol. These connections reflect Radius’s role in fostering collaboration across Ethereum’s expanding L2 landscape.
The team behind Radius includes individuals with backgrounds in cryptography, distributed systems, and blockchain security. According to Pantera Capital’s investment announcement, CEO AJ Park previously spent over a decade at Samsung Research and received Ethereum Foundation grants for work related to MEV-resistant AMMs. CTO Jongbeen Han holds a PhD in Distributed Systems and has led government blockchain initiatives in South Korea. CSO Tariz Jeong brings experience in financial mathematics and product development, while COO Jayden Kim has a background in software engineering and decentralized identity systems.
Radius uses TheRadius.xyz as its primary web address. .XYZ is widely adopted by blockchain and web3 projects for its short, flexible format and neutral branding. Radius extends this consistency across its digital presence, using @radius_xyz on X/Twitter and @radiusxyz on LinkedIn and GitHub. This coordinated use of .xyz helps create a unified identity across channels and reinforces the brand’s alignment with the broader ecosystem of blockchain platforms using .xyz domains.
