Launch of the wallet on the SEI testnet, allowing users to test and integrate wallet functionalities
Launch of the wallet on the Sei testnet, allowing users to test and integrate wallet functionalities and the wallet on the Sei mainnet, providing full access for users and enabling final testing and integration of core features.
Introduction of advanced features, such as DApp integration, to enhance the wallet’s functionality and expand its capabilities.
At the time of development, the Sei ecosystem lacked a dedicated non-custodial wallet aligned with its infrastructure and performance standards. Users depended on third-party tools that offered limited support and a fragmented experience.
Onsei Wallet was built to fill that gap — combining security, usability, and native Sei integration in one unified application. In addition to delivering a user-friendly and feature-rich product, Onsei sets a technical baseline for wallet development within the ecosystem. As an open-source project, it invites the developer community to contribute, audit, and expand upon its foundation — fostering innovation and long-term resilience across Sei’s fast-growing environment.
Users have complete control over their private keys, ensuring safe storage and full ownership and autonomy over their assets.
Manage multiple wallets effortlessly from a single device, allowing users to organize and switch between wallets without the need for multiple apps.
Onsei offers a secure environment for managing interactions on the SEI network. It uses biometric authentication and PIN protection to prevent unauthorized access, ensuring users can explore the SEI ecosystem with confidence.
The wallet’s design simplifies navigation, making it accessible even to those new to the crypto space. A seamless experience encourages broader adoption and satisfaction.
