Guide to sandboxnet access

Accessing Flow sandboxnet

The Flow sandboxnet is available for access at this URL:

1
access.sandboxnet.nodes.onflow.org:9000

For example, to access the network using the Flow Go SDK:

1
import "github.com/onflow/flow-go-sdk/client"
2

3
func main() {
4
  flowAccessAddress := "access.sandboxnet.nodes.onflow.org:9000"
5
  flowClient, _ := client.New(flowAccessAddress, grpc.WithInsecure())
6
  // ...
7
}

Generating sandboxnet key pair

You can generate a new key pair with the Flow CLI as follows:

1
> flow keys generate
2

3
🙏 If you want to create an account on sandboxnet with the generated keys use this link:

https://sandboxnet-faucet.flow.com/?key= cc1c3d72...

🔴️ Store private key safely and don't share with anyone!
8
Private Key      246256f3...
9
Public Key       cc1c3d72...

Note: By default, this command generates an ECDSA key pair on the P-256 curve. Keep in mind, the CLI is intended for development purposes only and is not recommended for production use. Handling keys using a Key Management Service is the best practice.

Account creation and token funding requests

Accounts and tokens for testing can be obtained through the sandboxnet faucet. If you generated the keypair through the CLI, you can click on the URL provided to create an account and request sandboxnet FLOW tokens.

Important smart contract addresses

You can review all available core contracts deployed to the sandboxnet to identify which ones you want to import.
