2key Network

2key Network was an Israeli technology company that developed a decentralized protocol on the Ethereum blockchain. Its core innovation was the "Smart Link," an HTTP link embedded with a smart contract. This technology was designed to create a transparent and multi-step tracking system for digital referrals, allowing any shared link to become part of a trackable and rewarded marketing campaign. The mission was to disintermediate the digital advertising industry by fairly rewarding every user in a referral chain who contributed to a conversion, rather than just the last click. The project held a token sale but appears to have ceased active development and community engagement since 2021.
