Choosing a Testnet
Solana maintains several testnets, each featuring a Solana-owned validator that serves as an entrypoint to the cluster.
Current testnet entrypoints:
- Stable: devnet.solana.com
Application developers should target the Stable testnet. Key differences between the Stable testnet and what will be mainnet:
- Stable testnet tokens are not real
- Stable testnet includes a token faucet for application testing
- Stable testnet may be subject to ledger resets
- Stable testnet typically runs a newer software version than mainnet
- Stable testnet may be maintained by different validators than mainnet
The Beta testnet is used to showcase and stabilize new features before they are tagged for release. Application developers are free to target the Beta testnet, but should expect instability and periodic ledger resets. Regarding stability, all that can be said is that CI automation was successful.
Get Testnet Version
You can submit a JSON-RPC request to see the specific software version of the cluster. Use this to specify the software version to install.
curl -X POST -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1, "method":"getVersion"}' devnet.solana.com:8899
Example result:
{"jsonrpc":"2.0","result":{"solana-core":"0.21.0"},"id":1}
Using a Different Testnet
This guide is written in the context of devnet.solana.com, our most stable
cluster. To participate in another testnet, modify the commands in the following
pages, replacing devnet.solana.com with your desired testnet.
