Case Studies

Arbitrum is designed to empower builders.


“We couldn’t be happier to be building on and together with Arbitrum. As one of its earliest projects, we’ve grown together with the Arbitrum network since practically day one.” – Karel Vuong, Co-Founder of Treasure.

The Graph

The Graph is scaling on Arbitrum — increasing the speed of transactions and significantly decreasing gas costs for everyone participating in the protocol — from the 40K+ subgraph developers to the combined 14K+ Indexers, Curators, and Delegators powering The Graph Network.


"Arbitrum isn’t just a technology or a subset of Ethereum; it's become an incubator for innovation both in creating better blockchains and sparks creativity in Defi and gaming that simply wasn’t possible before within Ethereum itself." – the GMX team.
