Flow Testnet

Accessing Flow testnet​

The Flow testnet is available for access at this URL:


_10
access.devnet.nodes.onflow.org:9000

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


_10
import "github.com/onflow/flow-go-sdk/client"
_10
_10
func main() {
_10
flowAccessAddress := "access.devnet.nodes.onflow.org:9000"
_10
flowClient, _ := client.New(flowAccessAddress, grpc.WithInsecure())
_10
// ...
_10
}

Generating testnet key pair​

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


_10
> flow keys generate
_10
_10
🙏 If you want to create an account on testnet with the generated keys use this link:
_10
https://testnet-faucet.onflow.org/?key= cc1c3d72...
_10
_10
_10
🔴️ Store private key safely and don't share with anyone!
_10
Private Key 246256f3...
_10
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 testnet faucet. If you generated the keypair through the CLI, you can click on the URL provided to create an account and request testnet FLOW tokens.

Important smart contract addresses​

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