Interacting with the Hatch Action

Introduction

We’ve implemented our new contract functionality for hatching a BabyChick NFT from a ChickEgg NFT. Now we’ll deploy our contract to the testnet and interact with it to hatch our own NFT on the testnet.

Deploying Our Contract

We can deploy our now updated contract to the testnet. As before, even through we are deploying an updated contract to our account, any tables and data that existed before will not be destroyed in this process.

Let’s unlock our wallet:

cd /wax
cleos wallet open -n testwallet
cleos wallet unlock -n testwallet --password="$(cat ./secrets)"

No we will deploy our contract:

cleos -v -u https://testnet.wax.pink.gg set contract waxcourse123 ./babychicks/build/babychicks -p waxcourse123@active

This command may give you an error if you do not have enough RAM purchased for your account to use:

Reading WASM from /wax/babychicks/build/babychicks/guestbook.wasm...
Publishing contract...
Error 3080001: Account using more than allotted RAM usage
Error Details:
account waxcourse123 has insufficient ram; needs 81572 bytes has 9592 bytes
Stack Trace:
resource_limits.cpp:235 verify_account_ram_usage

In this case, we need to buy RAM for our account. This is a useful command to have bookmarked:

# Remember to change waxcourse123 to your account name
cleos -v -u https://testnet.wax.pink.gg \
  system buyram waxcourse123 waxcourse123 "500" --kbytes \
  -p waxcourse123@active

If everything succeeded, you will see similar output to the following:

In the next section, we’ll send the contract a ChickEgg NFT to test it.

Hatching an Egg

We’ll use AtomicHub for the Wax Testnet to test out our new contract functionality.

Here, we’ve minted and transferred a BabyChick to the account darkemblemts. You’ll want to create a separate account using https://waxsweden.org/create-testnet-account/ to test non-admin functionality and ensure your Smart Contract code works correctly in the context of non-admin users.

Scroll down a bit and you will see a section that says “Transfer”:

Fill in the details for the transfer: To waxcourse123 and Memo hatch:

Once you confirm through Anchor, you will see this message:

Once the wax-orng send a random value back to the contract, it will mint a BabyChick:

Conclusion

We’ve successfully implemented, deployed, and tested our NFT Smart Contract that lets users hatch their NFTs! The Smart Contract we’ve implemented in these last set of tutorials provides quite a bit of interactive functionality that you can build on to give your NFT collection its own unique properties to make it stand out.
