Our services:
LinkRiver is a Chainlink node service provider that offers infrastructure and software solutions to connect smart contracts to real-world data and off-chain computation.
Our Chainlink nodes participate in various Decentralized Oracle Networks powering the Chainlink Data Feeds, Proof of Reserve and Keepers on a variety of networks.
We further offer the development of External Adapters to easily integrate custom computation and any public or private web API into your smart contracts.
Our team is constantly researching the latest technological advances and provides consulting on the deployment and maintenance of reliable Chainlink node environments.
In order to hold up the sophisticated security and latency requirements of the leading oracle solution, our technical infrastructure is permanently monitored and highly available.
