PurposeCritters Basics

What are PurposeCritters?

PurposeCritters are digital creatures that you can adopt, train, battle, trade, and play games with. The magic behind PurposeCritters is that all the in-game characters (aka PurposeCritters) are blockchain-based non-fungible assets (NFTs), meaning each critter is unique, provably rare, and owned by you. Each PurposeCritter has a unique genetic code that is recorded on a blockchain and is interpreted by the application.

Ok, then what is PurposeCritters..but like the game/company?

PurposeCritters are NFT collectables in the form of an interactive critter collecting and battling adventure game, and will be available to use in future Purposeverse game releases.

Does it cost money to play PurposeCritters?

Yes, but only to buy your initial critters. To play PurposeCritters you must purchase the critters you want using Ether (ETH) and then every game thereafter is free to play. Common critters start as low as the equivalent of $5 paid in ETH. Buying just one PurposeCritter grants you access to all our future games and content as well as future updates and expansions!

PurposeCritters Marketplace and Exchange.

PurposeCritters bought in the Marketplace are released by the PurposeCritters team at level 1. Players can upgrade their critters through gameplay. Players can monetize their gameplay, level upgrades, and achievements by selling their critter in the Exchange for a higher price than they purchased it for, but only if other players are willing to buy them. The Exchange is a player to player marketplace to sell experienced critters between users. However, it does cost a small transaction fee called “Gas” to list items on the Exchange, so choose your transactions wisely.

Is there an ICO?

We do not plan to launch an ICO. Elements of the game will be tokenized in the future like experience points, food, currency, and other in-game resources.

When is the main PurposeCritters launch?

We are currently in BETA and will be launching later this year. Check out the Discord for whitelist opportunities and the most up to date news on launch!

Digital Creatures across “Infinite Virtual Worlds”? How?

Adopting a PurposeCritter will give you access to the PurposeCritter game, all future updates and expansions, as well as the ability to take your critter into future Purposeverse games.

Is there a roadmap of expected features / timeline?

A roadmap of our expected features is in development and will be released in the Discord server.


Can I pay with a Credit or Debit Card?

Not yet. You need to buy Ethereum to play. Here’s how:

  1. Buy Ether (ETH): Coinbase is the most reputable and easiest for beginners.
  2. Install the MetaMask Browser Extension (Google Chrome | Mozilla FireFox | Brave)
  3. Transfer ETH to MetaMask (Explainer Video)
  4. That's it! Once MetaMask is installed, you're ready to buy and play!
Do you take my currency? Like USD?

We currently only accept Ether (ETH) and do not accept Fiat currencies like US dollars or Euros for our transactions. Opening this avenue for payment is a work in progress.

About Critters

How many critters are there?

While it is necessary to have market scarcity in order to protect the value of the players' purchases, there will always be common critters in the Marketplace to ensure access to PurposeCritters for everyone. However, specific critters and attributes will remain limited and rare.

What are the different Rarities?

PurposeCritters are subdivided across six different rarity classes—Common, Bronze, Silver, Gold, Platinum, and Diamond.

How does Rarity affect the gamer’s experience?

Rarity impacts in-game statistics at an increasing rate as the critter levels. Rare critters are significantly harder to maintain but can have a critical edge in certain comcritteritions when trained to high levels. Rare critters come with unique aesthetics as well.

What can I do with my PurposeCritter once I have it?

PurposeCritters can be immediately put to use in the battle minigame. Expect constant rollouts of new minigames from the development team. All of your successes can be put to use to make your critter stronger and improve your skills as a player.

Backend Technology

What is a blockchain?

A blockchain is a fancy database that keeps a permanent and unchangeable record of all data transfer on it. This data is secured by a global network of computers that earn a fee for lending their computer’s resources to confirm new transactions. On the Ethereum blockchain, that “fee” is known as Ether (ETH).

What is “Gas” on Ethereum and why is it required?

When submitting a transaction on the Ethereum blockchain users must pay a fee to the “miners” who run the network. The higher the gas price the more likely a “miner” will accept the transaction and process it quickly. The lower the gas price, the less likely your transaction will process and it may not confirm at all. We recommend all users to pay close attention to the cost of gas before submitting a transaction because setting it too low risks wasting your "gas" and setting it too high can be expensive.

What blockchain are PurposeCritters based on?

PurposeCritters are ERC-721 non-fungible tokens (NFTs) built on Ethereum. Ethereum is the blockchain of choice for many decentralized applications (dApps) as well as token developers because it is widely used and has a large development community.

What are non-fungible tokens (NFTs)?

The ERC-721 framework allows tokens built on Ethereum to be NFTs. NFTs are uniquely generated assets that have assigned and unique properties. Each one is generated with a unique ID hash that contains identifying data no other token has.

How are critters generated?

Smart contracts generate each critter with a unique hash that dictates their characteristics.

How are critters emitted to the marketplace?

Critters are emitted to the marketplace based on total player activity within the PurposeCritters system.

What makes critters unique?

Each asset is generated with a unique genetic code. It’s possible to interpret these genes differently across multiple games allowing unique game experiences.

Is PurposeCritters playable on mobile yet?

While the in-game assets are playable on mobile, it’s currently necessary to have the MetaMask integration to play. In the future, your tokens can be stored on a mobile browser like Toshi and in 3rd party wallets.

Are there any Integrations with other decentralized applications?

3rd party dApp integrations are a work in progress. We are strongly considering pulling other non-fungible tokens into our game as well as allowing for our assets to be played within other games.

Does the platform scale?

We are actively working to pilot generalized state channel payments for transaction volume scaling and plasma side chains for game volume. PurposeCritters currently runs on top of a balanced legacy system / blockchain-based backend to ensure that only the necessary components are on-chain to limit the cost of “gas” (i.e network transaction fees).
