Both StarkWare and Matter Labs feature networks with cutting-edge technology in the form of zkRollups, that are pushing the boundaries on blockchain scaling, privacy, and efficient cryptography.

For networks that you can play with right now, StarkEx is live with four applications, DyDx and DiversiFi for trading, and ImmutableX and Sorare for NFTs. zkSync is live for payments with primitive NFT functionality featured with ZKNFT.

Although, of the two it is clear that StarkEx has demonstrated usage and performance that is far above that of zkSync. With metrics such as $185B in cumulative trading volume and a verifiable capacity of 9,000 TPS for trades, it stands not only as the most used zkRollup but the most used rollup overall when measured by total transaction volume – beating the likes of zkSync, Optimism, and Arbitrum by over 10x. With the launch of StarkNet this month, StarkWare will have produced a zkRollup that features full composability with general smart contracts – thought of by many to be years away from happening.
