Oko

Oko is an open-source embedded wallet stack that gives developers full control over authentication, signing, and key management architecture.

Key Features and Architecture

Everything is fully open source and Apache-2.0 licensed:

• Non-custodial, based on Multi-Party Computation (MPC)

• Key Management: Hybrid signing model utilizing TSS (Threshold Signature Scheming) plus SSS (Shamir’s Secret Sharing)

• Key Security: Signatures are generated via distributed key shares; private key never reconstructed.

• User Onboarding: Supports email/social logins; eliminates seed phrases and browser extensions.

• Unified Account: Unified global wallet address with native multichain support.

• Modular Architecture: Orchestrator, adaptors, MPC services, and signing logic are self-hostable and auditable.

Integration and Support

• Official Integration: Access enterprise-grade key share infrastructure, dedicated monitoring and operational support, and comprehensive Dapp Dashboard and User Dashboard interfaces.

• Self-Host (Open Source): Utilize the Apache 2.0 components for complete architectural control and customization.

Development

Prerequisites

• Postgres 17+

pg_dump

During development, key share node assumes the system has "pg_dump" executable. pg_dump should be installed while installing Postgres. One way to install on MacOS is as follows.

brew install postgresql@18
echo 'export PATH="/opt/homebrew/opt/postgresql@18/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
