Flow Testnet

Accessing Flow Testnet

Currently, there is an internal Testnet, available for access:

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

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

func main() {
  flowAccessAddress := "access.testnet.nodes.onflow.org:9000"
  flowClient, _ := client.New(flowAccessAddress, grpc.WithInsecure())
  // ...
}

Account Creation and Token Funding Requests

Accounts and Tokens for testing are available by request through the Flow Faucet

Generate a Key Pair for the Faucet

For Testnet, it's easy to generate a new key pair with the Flow CLI:

flow keys generate

By default, this command generates an ECDSA key pair on the P-256 curve.

Note: this tool is intended for development purposes only and is not recommended for production use.

Testnet Account Usage

Once you receive your account, you'll be able make use of that account using our SDK. Some examples are available here in the SDK repo:

Some of these examples

  • create_account
  • deploy_contract

Transactions will now require fees in order to complete.

Important Testnet Smart Contract Addresses

In order to access some of the contracts deployed to Flow Testnet, you can import them by using the following import addresses:

import FungibleToken from 0x9a0766d93b6608b7
import FlowToken from 0x7e60df042a9c0868
import NonFungibleToken from 0x631e88ae7f1d7c20
