Deploy on Pop Testnet

Once you have battle-tested your smart contract using unit and e2e tests, you are ready to test your smart contract on a live test network: the Pop Testnet.

Let's deploy.

Onboarding

The community Relay test network for Polkadot is Paseo.

Pop Testnet is connected to Paseo.

In order to deploy a smart contract on the Pop Testnet, we will need to fund the account with the native tokens. Remember, Pop Network uses DOT as its native token, which is the Relay network's native token: Polkadot Relay network. In this case, we are on Paseo, so the native token for the Paseo Relay network is PAS.

We will need to:

1. Fund our dev account on Paseo with some PAS tokens

2. Transfer those PAS tokens from the Paseo dev account to the Pop Testnet dev account

Fund the Paseo dev account

Use the Paseo faucet to fund Alice's Paseo account with some PAS tokens.

PAS tokens are the equivalent of DOT on Polkadot.

Alice's account address is: 5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY

Go to the Paseo faucet and request some PAS tokens for Alice.

Transfer from Paseo Relay Network to Pop Testnet

As Pop Network uses the Relay chain's native token as its native token, we will need to transfer some of the PAS tokens from Alice's account on Paseo to Pop Network so that we can then deploy the contract.

We will need to import Alice's account to a wallet and we can do so by using Alice's secret seed: 0xe5be9a5092b81bca64be81d212e7f2f9eba183bb7a90954f7b76361f6edb5c0a

The below examples use the PolkadotJs Wallet extension.

Remember this is for development purposes. In production you would already have an existing wallet to use.

Now that we have Alice's account in our wallet, we can use https://onboard.popnetwork.xyz for transferring PAS tokens to Pop Network. Make sure to authorize your wallet to connect to the site.

Cool! Now that you have some PAS tokens on the Pop Testnet, we can deploy our smart contract.

Deploy

Deploy the contract to Pop Network Testnet:

pop up contract --constructor new --args "false" --suri 0xe5be9a5092b81bca64be81d212e7f2f9eba183bb7a90954f7b76361f6edb5c0a --url wss://rpc1.paseo.popnetwork.xyz

└  Deployment complete

You can now take the contract address and check the chain state to confirm that the contract exists. Remember to use the resulting contract address for your deployment.

Let's add the contract to the Contracts UI in PolkadotJS Apps. Click on "+ Add an existing contract".

Add the contract address along with the flipper.contract file found inside flipper/target/ink/flipper.contract

You can now see your newly uploaded contract:

Done!
