Connect to Arbitrum
livepeer requires access to the Arbitrum network
for typical usage.
Connecting to a network
There are two ways you can connect to an EVM-compatible network: via a hosted API service or via your own self-hosted node. Connecting to a hosted API service is recommended for users that are getting started and you always have the option to switch to your own node later on.
Hosted API services
Hosted API services run Arbitrum nodes on behalf of their users. Popular
services include Infura and
Alchemy. Be aware that these services have their own
pricing plans. That being said, the latest versions of
livepeer should be able
to stay within the request limit for Infura's free tier at least for a single
The following examples describe the required flags to connect to an EVM-compatible network via Infura (all other flags omitted):
To connect to Arbitrum mainnet:
-ethUrl https://arbitrum-mainnet.infura.io/v3/<PROJECT_ID> # Visit https://infura.io to obtain a PROJECT_ID
To connect to Rinkeby:
-ethUrl https://arbitrum.rinkeby.rpc # Visit https://developer.offchainlabs.com/docs/public_testnet to obtain a URL
Self-hosted Arbitrum nodes
If you want to run your own Arbitrum node, set one up using the instructions from Offchain Labs.
Once your node is synced, connect
livepeer to the node with the following flags (all other flags omitted):
-network mainnet \
-ethUrl http://localhost:8545 # Assumes that your node is running on the same machine as livepeer
livepeer supports the networks listed below. The required flags for connecting
to a network are described (all other flags are omitted).
Arbitrum One is the production public network.
-ethUrl <ETH_URL> # URL for Arbitrum mainnet provider
Arbitrum Rinkeby is the public test network.
-ethUrl <ETH_URL> # URL for Arbitrum Rinkeby provider
Custom private networks where the Livepeer smart contracts are deployed can be used for development purposes.
-network <NETWORK_NAME> # Name of network
-ethUrl <ETH_URL> # URL for private network provider
-ethController <CONTROLLER_ADDR> # Address of the Controller smart contract deployed on the private network
Offchain networks that do not require interaction with the Livepeer smart contracts can be used for development purposes.
