Polkadex is a fully decentralised peer-to-peer orderbook-based cryptocurrency exchange for the DeFi ecosystem built on Substrate. It combines the benefits of Centralised Exchanges (CEXes) and Decentralised Exchanges (DEXes) into one, solving the issues that plague CEXes while also tackling current issues in DEXes.

How does Polkadex use OnFinality?

“(For community inclusiveness and) for those subset of users who want to just, you know, one-click deploy the validator and don’t want to go through the 9 yards of spinning their own nodes.”
