How to mint your Happy Hopper
- Create a Shelley-Era Cardano wallet and fund it with enough ADA to cover the Hopper cost and transaction fees. We recommend Daedalus for high-traffic drops. Check our FAQ for more info on Cardano wallets.
- Never attempt to purchase an NFT from an exchange. They do not support them (and you can’t control your ADA staking)!
- Locate the “Send” tab in your chosen wallet, and identify the receiver/receiving address field.
- Return to the Happy Hoppers website, and click the Mint a Hopper! button.
- You should see a mint window similar to the one shown on the right, but if your browser or device does not support Javascript you will be taken to a separate page with the same information.
- Click the copy button to copy the sale address to your clipboard, then paste the address into the receiver field. Enter 42 into the ADA amount field.
- After pasting any crypto address, you should always check to ensure the last few characters of the address match what you copied.
- Click send, double-check that the details are correct, then enter your spending password and click send again.
- Depending on Cardano network load, you should expect to see your NFT within a few minutes to a few hours. If your transaction was received after Hoppers are sold out or for the wrong amount, you will receive a refund instead.
- To view your NFTs, go to Pool.pm and paste your receiving address into the search field.




What is a Happy Hopper?
Hoppers are frogs once found hopping happily from lily pad to pad in their peaceful home around the blissful Lake Cardano. But danger now looms through the mist. Hulking vehicles with sheening yellow paint advance towards the hoppers’ home, leaving doom in their path.
The peace loving frogs band together in a desperate attempt to protect their hearth and home. They now call themselves the Happy Hoppers Club, and they need your help to save Lake Cardano.
11,111 newly appointed members of the Happy Hoppers Club are nearly ready to assemble as NFTs in their leaders’ Cardano wallets! They are made up of over 100 hand-drawn assets created by the amazing and community-adored artist, oodon.

Frequently Asked Questions
Wen?

How many Hoppers are there?
There will be 11,111 Happy Hoppers.
111 have been reserved for promotions, promoters, giveaways, and the 5 1/1 team Hoppers.
The other 11,000 will be available for minting soon.
How do I get a Happy Hopper?
In order to buy a Happy Hopper, you must whitelist through this website. Even if you whitelisted through Discord for the pre-sale, you must whitelist again if you wish to buy another Hopper. We will share the link here and elsewhere when whitelisting period begins.
After a dedicated whitelisting period, Hoppers will be made available through a sale address provided by the team. The address will only be provided on the website, the staff-only announcements channel on Discord, and our official Twitter account.
Once the sale is live, you will send 42 ADA to the provided sale address from a Shelley-Era Cardano Wallet (see “What wallets can I use?”). If your address is on the whitelist, you will receive the NFT.
You will only be able to purchase one NFT per 12 hour period to a whitelisted address.
Do not send ADA to any address sent to you in DMs, or posted in a public channel. We will never DM you a sale address.
How many Hoppers can I buy?
During the pre-sale, each person who is whitelisted will be allowed one Happy Hopper mint.
Once the public sale is live, there is no limit to how many Happy Hoppers Club NFTs you can buy.
However, you can only mint one Hopper per transaction.
How long does it take to mint?
Under normal conditions, you should receive your NFT within 2-5 minutes of your payment being confirmed on the blockchain.
However, when the blockchain is at or near capacity (which is likely to be the case during the minting of very popular projects) things move more slowly.
It can unfortunately take wallets anywhere from 5 to 60 minutes or so to send out transactions during these times.
In order to minimize the likelihood of clogging the blockchain, and leave space for others to continue using Cardano, we will limit our minting capacity to 50% of a block.
Because of this, we ask that you be prepared for a possible wait time of a few hours to receive your mint.
What wallets can I use?
You can use any wallet that supports native tokens on Cardano, also known as “Shelley-Era” wallets.
We recommend you run Daedalus if possible. It is the only wallet that works reliably during periods of high blockchain traffic. Unfortunately, it has demanding system requirements.
Whenever you make a wallet, be sure to take extreme care to secure your seed. No one can help you recover a lost seed phrase, and if it falls into the wrong hands, your wallet is theirs to command.
Here are all the wallets that the team has used and confirmed working with Cardano tokens.
Daedalus
Full node wallet, most reliable transaction times.
Nami
Lightweight browser extension with NFT previews.
CCWallet
Power web wallet with NFT previews.
ADALite
Lightweight website wallet.
Yoroi
Browser extension & mobile app. Slowest transactions.
Notice
Seeds can be restored cross-wallet. You can even run two wallets at the same time with the same seed.
Nami wallets work a bit differently however, and are not smoothly interchangeable like this.
Will there be a whitelist or pre-sale?
Yes. Details for the pre-sale are posted exclusively in a pre-sale-info channel in our Discord.
The public whitelist will be available through this site, and we will include more details here and elsewhere on the site when the time draws near.
What does my Hopper do?
We have a number of plans and ideas to make holding your Happy Hopper even more exciting, including multiple kinds of transformative utility!
Why hold a Hopper? (Roadmap?)
For the community! We are building a collection of owners that are true lovers of CNFTs! We hope fans of Happy Hoppers, from new holders to whales, will come together as friends to learn together and share our favorite projects.
Additionally, there will be community events available only to holders. Check the roadmap on the about page for more info.
How did Hoppers come to be?
In late August, OutOfTheWorld and Jub discussed their dream NFT. Naturally, oodon’s name came up, as both are huge fans of his work. A few days later, oodon was on board!
A firm plan of action was formed, and pastaplease was contacted due to his experience and the team’s affinity for DexoWorlds.
Next a website was needed, and for that TelFiRE was chosen, having created the websites for Wizard Crypt and Horror Punks.
All of us have been in the CNFT space since early 2021. For more information about the team, check the team section on the about page and/or this tweet thread.
Who holds my Hopper’s copyright?
You do! Maybe you want to create a T-shirt, Mug, etc, creating a new piece of work, featuring your Hopper, no problem. You can do all these things and more, as long as you are holding the Happy Hoppers Club NFT.
You can not sublicense your license to third parties. You can transfer your license by selling your Hopper. The new holder will then be the license holder.
Happy Hoppers Club fully supports Commission-based Derivative Works i.e. an artist to create a new piece of work, featuring your Hopper that you personally request/pay to be created.
Are royalties charged on resale?
If you are using a marketplace that supports the proposed Cardano 777 royalties standard, we will collect 3% of the resale price. 50% of the royalties go into a fund to provide future utility to holders. The other 50% is used to support future development.
The royalties are only applied to the main collection policy ID. The promotional NFTs on our secondary policy are not subject to royalties.
Why are Hoppers on Cardano?
The Cardano Blockchain offers incredibly low cost minting and transaction fees, and most importantly, a fantastic community.
What are Swanky Swimmers (tadpoles)?
Swanky Swimmers are the cute baby Hoppers born at Lake Cardano.
There are 1,111 tadpole NFTs of 11 different skins. They are exclusively available through our Discord, so join for further details and a preview!

What is a CNFT?
A CNFT is an NFT on the Cardano blockchain.
NFT stands for non-fungible token, which is a type of cryptocurrency asset with only one supply. Standard, or “fungible” tokens have two or more supply, and are all interchangeable with each other. On the other hand, an NFT is completely unique, and not interchangeable with any other asset.
NFTs function as digital collectibles, but with a lot more possibilities. It’s possible to verify ownership of an NFT, and this opens up a host of possible benefits to holders.
