Dymension Mainnet RPC Endpoints & API

EVM, CometBFT and Cosmos REST access to the Dymension Hub

Connect to Dymension Mainnet. Use EVM JSON-RPC for blocks and contracts, CometBFT to check the Hub’s block height and sync status, and Cosmos REST to query its modules.

Dymension Mainnet RPC Quickstart

Item	Value
Network	Dymension Hub mainnet
Native token	DYM
EVM Chain ID	1100 (0x44c)
Cosmos network ID	dymension_1100-1

Check the EVM RPC over HTTPS

Run the HTTPS curl example above. It sends an eth_blockNumber POST to the public EVM JSON-RPC endpoint. The response’s result is a hexadecimal block height. To confirm the chain, use eth_chainId and check that it returns 0x44c.

Check the Hub’s consensus status

curl -fsS 'https://dymension.api.onfinality.io/tendermint/public/status'

Confirm result.node_info.network is dymension_1100-1, then check result.sync_info.latest_block_height and catching_up. Use /block on the same CometBFT base URL for block details. For Cosmos SDK module queries, use the REST endpoint.

When to use the Hub RPC or a RollApp RPC

The endpoints on this page connect to the Dymension Hub. Use them to query Hub blocks, transactions and chain state. To call a contract deployed on a particular RollApp, use that RollApp’s RPC URL and chain ID. The Dymension documentation explains how the Hub and RollApps fit together.

Use the public endpoints for connection checks and small reads. For a production service, check the RPC plans and confirm method support and response-unit costs in the Dymension method reference.
