Welcome to
Arbitrum Builders Cohort
A collaborative initiative designed for building dapps and tools on the Arbitrum ecosystem.
A place for builders to contribute and learn, where a handpicked group of high-impact builders receives targeted support, mentorship, and funding for their contributions through monthly on-chain streams.
Progress is tracked transparently through public updates, contribution logs, and on-chain activity, encouraging a culture of accountability and shared learning.
Focus areas: DeFi projects, MEV solvers, AI agents and TEEs (Trusted Execution Environments), DAO transparency tools.
