This document summarizes the CryptoCats project, which allows users to collect and trade unique digital cat tokens on the Ethereum blockchain. Some key points: - CryptoCats are unique 8-bit digital cat images represented as ERC-721 tokens on Ethereum, with each cat having different attributes stored on the blockchain. - The project started as a small MVP with 12 cats and 6 users to explore digital asset ownership and non-fungible tokens on Ethereum. - As the project grew, it required developing smart contracts in Solidity, building frontend interfaces, and deploying to Ethereum testnets and ultimately the mainnet. - Owning CryptoCats provides benefits like

CRYPTOCATS?

DIGITAL ASSET OWNERSHIP ON THE BLOCKCHAIN

5. Digital collectible 8bit cat.
Each cat has a unique
number which correlates to
the array in the contract
Each cat is a token and the
token ownership is stored
on the Ethereum Network.
We are exploring non-
fungible tokens, where each
has different attributes.
A composite image with all
the cats in a release is
hashed (SHA-256) and is
tied to the contract.

9. WHY
8-BITComes from a time when there was limited
capacity. We wanted to be true to our DNA, the
best way for us engineers to do art in the
crypto world.

THE SIMPLEST USER
JOURNEY:
VIEW, CLAIM, SHARE

12. cryptocats26
There's hardly
anything interesting
you can do on Mobile
yet
UX/UI:
Metamask helps but it
has glitches
and requires a bit
of set-up
Ethereum is slow.
It's early days for
error handling from
contract responses

13. USER TESTING
cryptocats26
Exploring where people use
cats, how they feel about them.

14. UNIQUE
BLOCKCHAIN
FEATURES TO
EXPLOIT:
Unbreakable Ownership
There's nothing like owning your own
cat on the blockchain. Bringing a strong
sense of authentic ownership to the
digital world
Digital Scarcity
Exclusiveness, FOMO and the supply and
demand dynamic creates interesting
games like the notorious Cat #52
Transparency
Gives bragging rights to your cat
ownership, everyone can see the real
owner

Decentralised Ethereum environment challenges
Remix browser IDE and Infura API are useful
