Arabica devnet ​

Arabica devnet is a testnet from Celestia Labs that is focused exclusively on providing developers with enhanced performance and the latest upgrades for testing their rollups and applications.

Arabica does not focus on validator or consensus-level testing, rather, that is what Mocha testnet is used for. If you are a validator, we recommend testing your validator operations on the Mocha testnet.

Network stability and upgrades ​

Arabica has the latest updates from all Celestia's products deployed on it, it can be subject to many changes. Therefore, as a fair warning, Arabica can break unexpectedly, but given it will be continuously updated, it is a useful way to keep testing the latest changes in the software.

Developers can still deploy on Mocha testnet their sovereign rollups if they chose to do so, it just will always lag behind Arabica devnet until Mocha undergoes Hardfork Upgrades in coordination with Validators.

Network details ​

Software version numbers ​

Integrations ​

This guide contains the relevant sections for how to connect to Arabica devnet, depending on the type of node you are running. Your best approach to participating is to first determine which node you would like to run. Each node’s guide will link to the relevant network in order to show you how to connect to them. Learn about the different endpoint types in the Cosmos SDK documentation.

Production RPC endpoints ​

These RPC providers are meant to be used in production environments.

Community RPC endpoints ​

RPC endpoints and types of nodes you can run in order to participate in Arabica devnet:

You can find the status of these endpoints.

Using consensus endpoints with DA nodes ​

Data availability (DA) RPC endpoints for bridge node sync ​

These RPC endpoints allow bridge nodes to sync blocks from the Celestia network. For users, they will need to provide a –core.ip string from a consensus node’s URL or IP that populates a default RPC port at 26657 to their respective DA node.

Data availability (DA) gRPC endpoints for state access ​

These gRPC endpoints for DA nodes provide state access for querying the chain’s state and broadcasting transactions (balances, blobs, etc.) to the Celestia network. For users, they will need to provide a –core.ip string from a consensus node’s URL or IP that populates a default gRPC port at 9090 to their respective DA node.

celestia <da_type> start –core.ip <url> -–core.grpc.port <port>

celestia <da_type> start –core.ip <url> -–core.grpc.port <port>

RPCs for DA nodes to initialise or start your celestia-node to Arabica devnet with can be found in the table in the "Direct endpoints with open ports" section above.

As an example, this command will work to start a light node with state access, using default ports:

celestia light start --p2p.network arabica \
  --core.ip validator-1.celestia-arabica-11.com

celestia light start --p2p.network arabica \
  --core.ip validator-1.celestia-arabica-11.com
