Oko Welcome

Web3 onboarding does not need to be complicated. Oko makes onboarding to your application easy, fast, and secure. No wallet installs, no recovery phrases, no friction.

Using the latest advances in cryptography, Oko delivers a seamless experience by integrating the security of blockchain wallets directly into web or mobile apps. Users can sign up with familiar login methods (email, social, or SSO) while enjoying the benefits of true crypto ownership — secure transactions, asset custody, and compatibility with decentralized applications — all without the friction of managing private keys or seed phrases.

Why Oko​

One of the biggest challenges in crypto is managing wallets across multiple chains. Keplr (the team behind Oko) has solved this with a browser extension that empowers users to securely self-custody their assets and connect effortlessly to dApps across ecosystems.

However, onboarding remains one of the biggest barriers for users who are less familiar with crypto. In Web3, the core advantage is that users bring their own wallet to every application—unlike Web2, where accounts are tied to individual platforms. But this Web3 model introduces two major challenges:

  • Managing recovery phrases or private keys
  • Installing browser extensions or mobile apps

Embedded wallets aim to remove these hurdles by providing a smoother entry point. Yet, existing solutions sacrifice one of Web3’s defining strengths: interoperability across applications and blockchains. They tend to create isolated accounts for each application, essentially reverting to a Web2-style model.

Oko solves this problem. It delivers seamless onboarding while preserving true Web3 interoperability, allowing users to access multiple applications with the same wallet address.

With secure architecture, intuitive UX, and native multichain support, Oko empowers both developers and users to build, transact, and scale with confidence.
