What is KEY (KEY)?
SelfKey is a decentralized identity management project built on the Ethereum blockchain. Its primary objective is to provide individuals and organizations with full ownership and control over their digital identities and personal data, a concept known as self-sovereign identity. By moving away from centralized databases, the project aims to reduce the risk of massive data breaches and identity theft. The project functions through a few core components. The first is the SelfKey Wallet, a secure application where users can store their identity documents and digital assets. A defining characteristic of this wallet is that personal information is stored locally on the user's device rather than on a central server or the blockchain itself. Users only share specific data with third parties through a secure permission system when required for verification. The second major component is the SelfKey Marketplace. This is a dedicated platform where users can access a wide range of financial, corporate, and immigration services. Through the marketplace, individuals can apply for bank accounts, register companies, or even explore residency and citizenship programs. Because the user's identity is already verified within the ecosystem, these processes are significantly more efficient than traditional methods. The native token of the project is KEY, which functions as a utility token within the network. It is used to facilitate transactions in the marketplace, pay for identity verification services, and enable access to certain features. It also serves as a reputation and staking mechanism to ensure the integrity of the participants within the ecosystem. The project has evolved to include the SelfKey DAO, a decentralized autonomous organization that allows token holders to participate in the governance and future development of the platform. More recent updates have focused on integrating artificial intelligence and zero-knowledge proofs to enhance privacy and security. These technologies allow for identity verification without the need to expose sensitive underlying data, further strengthening the project's commitment to digital sovereignty and user privacy in the Web3 space.

KEY (KEY) FAQ
SelfKey has merged with SingularityDAO and Cogito Finance to form Singularity Finance (SFI). This strategic move transitions the project from a dedicated identity management platform into a comprehensive Layer-2 ecosystem focused on the AI-driven economy. By combining these technologies, the new ecosystem aims to integrate decentralized identity (DID) with AI-DeFi services and the tokenization of Real-World Assets (RWA).
As part of the merger, KEY tokens are being migrated to the new SFI token. Holders must follow specific migration portals to claim their new tokens, with reports indicating a conversion ratio of 1 KEY to 0.1 SFI. As the SelfKey brand is absorbed into the Singularity Finance ecosystem, users are encouraged to move their assets from exchanges or non-custodial wallets to the official migration platform to ensure they receive their SFI tokens.
While certain platforms delisted KEY in late 2024, the token remains available for trading on global exchanges such as LBank. Users looking to manage their holdings or prepare for the migration can deposit their KEY tokens to LBank for continued access to liquidity. It is recommended that holders move their funds from platforms no longer supporting the token to active exchanges like LBank or to private hardware wallets.
The KEY token is used for "Proof of Reputational Stake" within the SelfKey marketplace. Notaries and service providers are required to stake KEY to offer their services, ensuring a layer of trust and accountability. If a provider misuses data, their staked tokens can be penalized. Additionally, users use KEY to pay for various services, including identity notarizations, residency applications, and the opening of financial accounts.
The SelfKey Identity Wallet is a non-custodial solution that stores identity documents locally on the user's own device rather than on a centralized server or the blockchain. This prevents data breaches associated with central databases. To prove attributes like age or nationality, the system uses "verifiable claims" or hashes. This allows users to confirm their identity to third parties without actually disclosing the underlying sensitive documents, maintaining true self-sovereign identity.
SelfKey is not discontinued; it has evolved through its merger into the Singularity Finance partnership. While the original SelfKey website may not show frequent independent updates, the project's development and community activity have shifted toward the new AI-focused Layer-2 ecosystem. The "SelfKey" brand is being integrated into Singularity Finance, which now manages the roadmap for the identity technology and the transition into the AI-DeFi space.
