SubQuery, Transform and Query the world’s data for a Web3 future. Every blockchain team has a need to process and query data quickly.

The thriving Polkadot/Substrate community is going to need a service that allows them to reliably find and consume data faster. For the web3.0 dream to be realised, it’s got to be as fast (if not faster) than centralised networks for the end user.

SubQuery enables better dApps by making decentralised data more accessible. Our service will allow users to extract, transform, persist, and query data initially, as well as connect and present data in the future.

SubQuery will be a core piece of infrastructure for the Substrate/Polkadot ecosystem.

Prime protocol makes your crypto work for you as collateral regardless of what chain it’s on or what kind of token it is. Rather than borrowing against each asset individually, you can take out a loan on any chain and it will be backed by the collateral value of your cross-assets.
