Dymension is a modular blockchain ecosystem created with the purpose of securing and connecting application chains, referred to as rollups, using the standardized Inter-Blockchain Communication (IBC) protocol. A modular blockchain specializes in specific functions instead of attempting to handle everything. Combining multiple specialized blockchains creates a more scalable and customizable system. For instance, rollups focus on execution and can offload tasks to other specialized modular blockchains.

Centered on play-to-earn gaming and decentralized finance (DeFi), the blockchain is overseen by the Dymension Hub. It improves data management with Data Availability Networks and provides a RollApp Development Kit for developers. Anchored by the DYM token, the network's operations and user rewards system were kickstarted through the Genesis Rolldrop, playing a pivotal role in Dymension's strategic growth in the blockchain sector.
