Sui Co-Founder Kostas Kryptos Unveils Havenex as Series A…

Sui co-founder Konstantinos “Kostas Kryptos” Chalkias has unveiled Havenex, an institutional digital-asset platform that is nearing completion of a Series A funding round while seeking regulatory authorization in Austria. Havenex is being developed as infrastructure through which banks, fintech companies, asset managers and other financial institutions can offer cryptocurrency and tokenized-asset services without constructing their own custody, trading and compliance systems.The company has not disclosed the size or valuation of its Series A financing. Current reporting says the round is close to completion, but neither a fundraising target nor participating investors have been publicly identified. Havenex is also not yet a regulated operating exchange. Its website says Havenex AG is currently undergoing authorization with Austria’s Financial Market Authority and will not provide regulated services until approval is received. The Vienna-registered company lists Grigorios Siourounis as its management-board member, while Chalkias, Mysten Labs co-founder Adeniyi Abiodun and Petros Pyloridis sit on its supervisory board.

Havenex Targets Banks Rather Than Retail Crypto Traders

Havenex is positioning itself differently from conventional centralized exchanges such as Coinbase or Binance. Its primary customers are expected to be financial institutions that want to provide digital-asset services under their own brands. Havenex plans to offer a white-label infrastructure layer incorporating institutional custody, trading, brokerage and yield-generating products through a single integration. The company says the platform will include cold and warm storage built to regulated standards, automated transaction-level compliance, audit-ready reporting and real-time counterparty exposure monitoring.Havenex also plans to incorporate multisignature security, hardware-based authentication and mechanisms intended to provide stronger verification of custody and solvency. Sui technology will form part of the platform, reflecting Chalkias and Abiodun’s backgrounds at Mysten Labs, but Havenex is not intended to operate exclusively within the Sui ecosystem. The company plans to integrate multiple blockchain networks, assets and bridging infrastructure depending on institutional requirements. That multi-chain approach is important for Havenex’s ambitions because regulated financial institutions increasingly require infrastructure capable of handling cryptocurrencies alongside tokenized traditional assets rather than exposure to a single blockchain.

HAV Token Adds Sui-Based Economic Layer

Havenex is simultaneously developing HAV, a Sui-based ecosystem token with a fixed maximum supply of 10 billion tokens. Haven Holding AG describes HAV as a MiCAR Title II crypto-asset and says its white paper has been notified to Austria’s FMA without the regulator raising objections. That notification should not be confused with Havenex receiving authorization to provide regulated financial services. HAV is currently scheduled for a fourth-quarter 2026 launch window.According to published tokenomics, 27% of supply is allocated to rewards and incentives, 25% to treasury, 16.5% to founders, 12% to investors, 8% to the team and advisers, 5% to liquidity, 3.5% to airdrops and 3% to compliance and regulatory expansion. Planned utilities include paying platform fees, staking-related benefits, trading-fee discounts, onboarding incentives and access to selected products. Havenex also intends to introduce a buyback program beginning in 2027, using a portion of trading-fee revenue generated by Havenex operating entities to purchase HAV from the market.The company explicitly says HAV provides no equity, voting, profit-participation or repayment rights. Havenex’s emergence comes as institutional cryptocurrency infrastructure increasingly shifts toward regulated, white-label models that allow banks to offer digital assets without surrendering custody and compliance oversight to conventional offshore exchanges. The immediate milestones remain financing and regulation.Closing the Series A would provide capital for Havenex’s development, but the more consequential step will be obtaining the FMA authorization required before its proposed regulated services can begin. Until then, Havenex remains an institutional platform in development rather than a live regulated exchange. Its combination of Sui-linked founders, European regulatory ambitions and a white-label model nevertheless makes it another significant attempt to connect blockchain markets directly with conventional financial institutions.
