Welcome to the OPUS API developer documentation. OPUS is a multi-chain API suite that supports single click staking experience and provides statistics on rewards, APY, and node performance.


OPUS is a multi-chain staking solution that enables users to stake digital assets across multiple chains on a single platform while retaining complete control over their funds.
It is aimed at expediting institutions' staking activities, streamlining the staking process, and enabling them to enjoy the benefits of higher rewards, increased efficiency, reduced costs, and unparalleled flexibility. The API offers a range of customizable features that cater to institutions' diverse needs, including an intuitive, user-friendly portal that enables users to track real-time rewards data on a single dashboard. Institutions can choose to stake their own assets using OPUS or provide staking services to their customers, creating a new opportunity for revenue generation.
Some benefits of using OPUS:
Institutions' needs can vary widely, and setting up staking operations often requires specific technical capabilities. After months of research, we developed OPUS to offer a range of customizable features that cater to all.
  1. 1.
    Highest Rewards and Tracking
Staking is one of the easiest and least risky ways to earn rewards on your crypto assets. However, tracking rewards across multiple networks can be a cumbersome process.
To combat this, OPUS features an intuitive, user-friendly interface that enables users to track real-time rewards data for multiple assets on a single dashboard. Additionally, OPUS offers the highest staking rewards, which include network emissions, transaction fees, and MEV (maximal extractable value).
With just a few clicks, users can earn rewards and download detailed reports on their staking rewards at any time, while retaining unparalleled transparency and control over their assets.
