Dymension RPC Endpoint
Flat-rate Dymension RPC provider and Dymension RPC node access: free tier, no KYC, HTTP. Dymension mainnet chain ID 1100.
https://rpc.swiftnodes.io/rpc/dymension?key=YOUR_API_KEYDymension is a Cosmos SDK Layer 1 that serves as the settlement and interoperability hub for application-specific rollups called RollApps. SwiftNodes serves the Dymension Hub's EVM JSON-RPC side; DYM is the gas and staking token.

About Dymension
Dymension mainnet launched on February 6, 2024, alongside DYM. RollApps settle to the Hub, which is aware of each RollApp, maintains its state, and connects RollApps to each other and to other Cosmos chains over IBC.
The Hub exposes an Ethereum-compatible JSON-RPC endpoint with EVM chain ID 1100 (Cosmos chain ID dymension_1100-1), so MetaMask and EVM libraries can read balances and send DYM. Many Hub features, such as staking, governance and IBC transfers, are Cosmos modules, so some state is only reachable through Cosmos APIs, not eth_ methods.
Common Use Cases on Dymension
- Holding and transferring DYM from EVM wallets
- Tracking RollApp settlement on the Hub
- IBC transfers between RollApps and Cosmos chains
- Staking and governance tooling
