Crypto exchange dYdX has launched a public testnet of its “v4” iteration, according to a July 5 announcement from the exchange’s development team. This marks the completion of “milestone 4” out of five, paving the way for a future v4 mainnet launch.

Once implemented on mainnet, v4 is expected to allow for “full decentralization” of the exchange.
