Sui Co-Founder Kostas Kryptos Unveils Regulated Exchange Havenex as Series A Nears Close Sui co-founder Kostas Kryptos said Havenex is currently raising a Series A round that is close to completion and has already applied for the licenses required for its planned operations. The platform is being built as regulated infrastructure for financial institutions to offer both digital and traditional financial assets, with a focus on verifiable custody, continuous proof of solvency, multisig security, quantum-resistant keys, hardware-based two-factor authentication, and self-custody and key-loss protection mechanisms. Havenex plans to use Sui technology where appropriate while also integrating assets, infrastructure and bridges from other ecosystems. Kostas said he will advise Havenex but will remain focused on Mysten Labs and Sui.
