HashKey’s Horizon hackathon picks

HashKey Chain has moved 28 teams into the next stage of its Horizon Hackathon, with DeFi projects including AssetFlow and OutcomeX among the named picks. (dorahacks.io) The Horizon event is scheduled on DoraHacks from March 10 to April 23, 2026, with registration closing April 15 and a listed prize pool of 40,000 USDT. The public hackathon page also shows 54 submitted builds and 375 participants. (dorahacks.io) HashKey framed the program as more than a prize contest. The event materials say winning and high-potential teams can get follow-on incubation and access to HashKey Group’s marketing, investment, and security-compliance units, plus outside partners including exchanges, audit firms, and venture capital funds. (eventbrite.com) A hackathon is a timed product contest, and this one is aimed at getting developers to build financial apps on HashKey’s blockchain. The official brief centers on four tracks — decentralized finance, payments finance, artificial intelligence, and zero-knowledge identity — with projects pitched around trading, on-chain financial infrastructure, and automated operations for DeFi protocols. (dorahacks.io) HashKey is using the contest to seed activity on a newer chain that is pitched as a compliant home for Web3 developers. The company’s developer materials describe HashKey Chain as infrastructure for smart contracts and decentralized finance, while its testnet explorer is already live for developers shipping code. (hsk.xyz) (testnet-explorer.hsk.xyz) Several of the public submissions show the kind of products HashKey is trying to attract. AutoPay AI says it is building an on-chain payment assistant, while HashPay describes itself as payroll software for crypto teams using recurring payments and auditable receipts on HashKey Chain.

DoraHacks still lists the Horizon Hackathon as running through April 23, 2026, leaving the selected projects to turn early momentum into products HashKey can keep inside its accelerator pipeline.
