# PUT Clusters

PUT Clusters

PUT maintains several different clusters with different purposes.

Before you begin make sure you have first installed the PUT command line tools

Explorers:

* <https://www.putscan.com/>

## Testnet\#

* Testnet is where the PUT core contributors stress test recent release features on a live cluster, particularly focused on network performance, stability and validator behavior.
* Testnet tokens are not real
* Testnet may be subject to ledger resets.
* Testnet includes a token faucet for airdrops for application testing
* Testnet typically runs a newer software release branch than both Devnet and Mainnet Beta
* Gossip entrypoint for Testnet: entrypoint.testnet.put.com:8001
* Metrics environment variable for Testnet:

```
export PUT_METRICS_CONFIG="host=https://metrics.put.com:8086,db=tds,u=testnet_write,p=c4fa841aa918bf8274e3e2a44d77568d9861b3ea"
```

* RPC URL for Testnet:<https://rpc-test.put.com>

Example put command-line configuration#&#x20;

```
put config set --url https://rpc.put.com
```

&#x20;

Example put-validator command-line#&#x20;

```
$ put-validator
--identity validator-keypair.json
--vote-account vote-account-keypair.json

The identities of the --known-validators are:

* `5D1fNXzvv5NjV1ysLjirC4WY92RNsVH18vjmcszZd8on` - Solana Labs
* `dDzy5SR3AXdYWVqbDEkVFdvSPCtS9ihF5kJkHCtXoFs` - MonkeDAO

* `9QxCLckBiJc783jnMvXZubK4wH86Eqqvashtrwvcsgkv` - Algo|Stake

## Mainnet Beta

A permissionless, persistent cluster for PUT users, builders, validators and token holders.

* Tokens that are issued on Mainnet Beta are **real** PUT
* Gossip entrypoint for Mainnet Beta: `entrypoint.mainnet-beta.put.com:8001`
* Metrics environment variable for Mainnet Beta:

```
export PUT_METRICS_CONFIG="host=https://metrics.put.com:8086,db=mainnet-beta,u=mainnet-beta_write,p=password"
```

* RPC URL for Mainnet Beta: [`https://rpc-test.put.com`](https://rpc-test.put.com)

Example put command-line configuration#&#x20;

```
put config set --url https://rpc-test.put.com
```

Example put-validator command-line#&#x20;

```
