Dymension Hub delivers critical services—security, liquidity, and interoperability—to RollApps, enabling them to function optimally without standalone infrastructure. This modular approach lets developers concentrate on creating innovative decentralized applications (dApps) while benefiting from scalable, low-cost connectivity via the Inter-Blockchain Communication (IBC) protocol.
Understanding RollApps
RollApps are modular Layer-2 blockchains within Dymension’s ecosystem. Unlike conventional blockchains, they rely on the Dymension Hub for core services, eliminating the need for independent infrastructure. This design accelerates the launch of scalable dApps.
The RollApp Development Kit (RDK)
The RDK streamlines RollApp deployment by integrating Cosmos SDK modules like:
- Bank: Token transfers
- Gov: On-chain governance
- Upgrade: Software updates
- IBC: Cross-chain bridging
Key innovations include:
- EVM smart contracts for RollApps
- Sequencers for transaction processing rewards
- Mint/Dist modules for token creation and reward distribution

Dymint (replacing Tendermint) allows RollApps to inherit Dymension’s security via sequencers, reducing costs and complexity.
Rollups vs. RollApps
| Feature | Rollups | RollApps |
|------------------|-------------------------|-------------------------|
| Scope | Scale single chain (e.g., Ethereum) | App-specific chains |
| Architecture | Off-chain transaction processing | Modular chains with Hub reliance |
| Interoperability | Limited | IBC-enabled |
RollApps offer superior customization, scalability, and cost-efficiency by leveraging Dymension’s modular framework.
Dymension’s Unique Value Proposition
- Modular Architecture: RollApps share Hub services, reducing deployment overhead.
- Built-in Liquidity: Facilitates seamless token swaps and asset pricing.
- IBC Protocol: Enables secure cross-chain communication ("Internet of RollApps").
- Flexible Data Solutions: RollApps can publish data to blockchains like Celestia or NEAR for optimal cost/performance.
👉 Why Dymension’s liquidity layer stands out
The DYM Token
DYM powers the network through:
- Staking: Secure the chain and earn rewards (~67% staking target; dynamic inflation).
- Gas Fees: Pay for transactions.
- Governance: Vote on protocol upgrades.
Tokenomics:
- Initial supply: 1B DYM (distributed over 5 years).
- 7% airdropped to Celestia stakers, Cosmos communities, and NFT holders.
