The Data Layer
for Web3

Decentralized, multi-purpose on-chain streaming oracle for applications and blockchains

Launch Syntropy Showcase

Syntropy is building an on-chain streaming oracle, providing decentralized and scalable way to access, retrieve and interact with real-time and historical on-chain data.

Full node

Syntropy creates an incentive layer for blockchain nodes to publish transactions in real time and historical data streams.

Syntropy Data Layer

Blockchain data becomes easily accessible for any application and is used to build derivative protocols and products dependent on real-time data.


Syntropy replaces reliance on RPC nodes and APIs and introduces a decentralised way to interact with the blockchain and build a new generation of scalable dApps.

Real-time data streams

We're creating a foundation for responsive dApps & blockchain services with real-time data streams for finalized transactions & mempool. Our open-source ecosystem allows instant data sharing between blockchains, fostering scalable communication and high-throughput in dApps.


Streaming historical on-chain data

Our goal is to unify real-time & historical data through decentralized streaming, contrasting with traditional APIs by providing instant data access. Our system incorporates historical data in real-time streams, allows detailed filtering, and is built for maximum redundancy & real-time data.

On-Chain Streaming Oracle

Real-time data issues hinder scalable, secure, decentralized blockchain solutions. On-chain streaming oracle is key for light clients, chain scaling, and rollups.

In the Data On-Chain Streaming Network, full nodes handle fraud proof construction and block data recovery, while light clients perform data sampling, approving or rejecting block data based on completeness and accessibility, without verifying all data.

The fastest on-chain and mempool data

Syntropy revolutionizes the way we access real-time blockchain data, providing on-demand, low-latency streams of transactional data directly from the mempool, all in a decentralized way

Aptos's blockchain data will be available for use at the forthcoming Hack Holland hackathon in Amsterdam.

Syntropy Chain

Syntropy Chain provides the authentication, authorization and accounting - all functions operated by nodes on Syntropy’s native blockchain and powered by our native NOIA token.

The token is the integral part of the solution - it serves as the gas for data in our ecosystem and it aligns incentives of the Syntropy’s On-Chain Streaming Oracle.

Get early access

On-chain data from any blockchain in one place

Leveraging Syntropy's real-time data streams users will be able to conveniently access data from multiple blockchains and applications in one place.
