Dymension RPC Integration: Connect with RollApps Using OnFinality RPC

Access Dymension RollApps with OnFinality RPCs and explore modular blockchain infrastructure powering Web3 scalability.

Billions of blockchain transactions rely on one invisible connector, the RPC. It enables dApps to communicate with blockchains, process transactions, and retrieve on-chain data. For teams adopting Dymension RPC on a Modular Blockchain Infrastructure, building on a reliable RPC is essential.

In this guide, you’ll learn how to access Dymension’s RollApps using OnFinality RPC, why Modular Blockchain Infrastructure matters, and what this partnership unlocks for projects building the next generation of Web3 applications.

Partnership Overview

The collaboration between OnFinality and Dymension enhances access to Modular Blockchain Infrastructure with enterprise-grade RPC endpoints and 99.99% uptime.By integrating OnFinality RPC into the Dymension network, developers can make their RollApps high-performance, low-latency, and reliably scalable.

Modular by Design

Traditional blockchains attempt to handle execution, settlement, and data availability in one monolithic system. Dymension separates these functions into specialised layers, increasing flexibility and throughput.

Each RollApp within Dymension operates as an application-specific rollup chain while remaining connected through shared security and verification.

Different RollApps can optimise for distinct priorities:

Gaming RollApps focused on ultra-low latency and high throughput.
DeFi RollApps prioritising security and deterministic execution.
Social RollApps built for scalability and responsive user experience.

This design, built with the Cosmos SDK and IBC (Inter-Blockchain Communication), enables horizontal scaling and seamless interoperability, reflecting how modular blockchains are redefining scalability across the industry.

About Dymension

Dymension is a modular chain launchpad that powers the creation of sovereign blockchains, called RollApps. It provides the liquidity, bridging, and interoperability layer connecting these RollApps across ecosystems.

Built using the Cosmos SDK and secured through IBC, Dymension allows developers to launch interoperable, scalable RollApps supported by its settlement layer.

Each RollApp posts its state roots and proofs to the Dymension Hub, ensuring verifiable communication and network integrity without depending on a single monolithic chain.

The Dymension Ecosystem Includes:

Dymension Hub: The Layer 1 settlement layer connecting and securing all RollApps.
Chain Launchpad:The platform where anyone can permissionlessly launch a RollApp chain, bootstrap liquidity using multiple base assets (like DYM, USDC, or KAS), and connect to external ecosystems via Dymension’s validator-powered bridge.
RDK (RollApp Development Kit): Developer toolkit for building and deploying custom RollApps.
IBC Connectivity: Interoperability with IBC-enabled Cosmos networks.

Dymension token lifecycle from launchpad to full blockchain ecosystem.

This structure empowers developers to build freely while Dymension ensures core layers of security, data availability, and inter-chain communication.

OnFinality Joins the Modular Stack

How Developers Can Leverage OnFinality RPC to Access Dymension

Developers can connect to Dymension using OnFinality’s Dashboard and public RPC endpoints:

STEP 1: Login into Onfinality Dashboard

STEP 2: Create an app on the dashboard

STEP 3: Select the Dymension Network from the network list.

STEP 4: You can use the RPC and WebSocket link given on the dashboard

STEP 5: Use it in your webApp or any of your application to communicate with Dymension

Example: You can check whether the RPC is active or not by using the following command on your cli:

Shell

curl --location 'https://dymension.api.onfinality.io/public' \
--header 'content-type: application/json' \
--data '{"id": 1, "jsonrpc": "2.0", "method": "eth_blockNumber", "params": []}'

Why Dymension + OnFinality Matters in 2025

Modular Blockchain Infrastructure improves scalability by decoupling core layers.
Dymension RollApps reduce congestion by offloading execution while preserving shared security.
OnFinality RPC delivers globally distributed, autoscaled endpoints for reliable performance.
The combination accelerates deployment and enhances visibility for on-chain builders.

Key Benefits and Use Cases

Benefits

Speed to Market: Launch a Dymension RollApp with managed endpoints and monitoring from day one.
Performance at Scale: Handle production traffic via OnFinality RPC without additional configuration.
Interoperability: Use IBC to communicate across Cosmos networks.
Flexibility: Choose between EVM, CosmWasm, or Move execution models.
Observability: Access real-time logs, metrics, and alerts.

Common Questions about Dymension RPC

Is Dymension EVM-compatible?

Yes. RollApps support multiple virtual machines, including EVM, CosmWasm, and Move, enabling Solidity-based dApps to migrate seamlessly.

How is a RollApp different from a traditional rollup?

A RollApp is Dymension’s app-specific rollup that posts proofs to the Dymension Hub while maintaining connectivity through IBC.

How can I create and deploy my own RollApp?

Use the RDK (RollApp Development Kit) to scaffold and configure your RollApp, then register it to interact with the Hub.
