Dymension RPC Endpoint

Fast, flat-rate Dymension RPC node provider — free tier, no KYC, HTTP & WebSocket.

Dymension is a Cosmos SDK Layer 1 that acts as a settlement and interoperability hub for app-specific rollups called RollApps. Its native token DYM secures the network, and the hub exposes an EVM-compatible environment.

About Dymension

Dymension launched its mainnet on February 6, 2024, alongside the DYM token and an airdrop to users across the EVM, Cosmos, and Solana ecosystems. The Dymension Hub is built with the Cosmos SDK and serves as the settlement layer for RollApps, modular app-specific chains built with the Dymension RollApp Development Kit (RDK).

RollApps rely on the Dymension Hub for security and IBC-based interoperability, and the RDK supports EVM smart contracts via Ethermint in addition to Cosmos SDK and CosmWasm modules. DYM is used for staking, governance, and securing the hub. The EVM-compatible endpoint corresponds to chain ID 1100, where standard Ethereum tooling works.

Common Use Cases on Dymension
