PetKingdom: A Blockchain-Based Play-to-Earn Virtual Pet Metaverse
The PetKingdom whitepaper was written and published by the PetKingdom core team at the end of 2025, in the context of the integration of digital pets and Web3 technology, aiming to address the pain points of centralized operations in traditional digital pet games and explore a new model for a decentralized, community-driven pet ecosystem.
The theme of the PetKingdom whitepaper is “PetKingdom: A Community-Built Digital Pet Metaverse.” What makes PetKingdom unique is its innovative mechanism of “pet NFTization + breeding economic model + DAO governance,” using blockchain technology to realize true ownership and scarcity of digital pet assets. The significance of PetKingdom lies in bringing unprecedented transparency, community autonomy, and asset value to the digital pet field, laying the foundation for a decentralized digital pet ecosystem.
The original intention of PetKingdom is to provide a fair, transparent, and vibrant decentralized platform for digital pet enthusiasts worldwide. The core viewpoint expressed in the PetKingdom whitepaper is: by minting digital pets as unique NFT assets and combining decentralized autonomous organization (DAO) for community co-governance, it ensures users’ complete ownership and scarcity of digital pet assets, while building a sustainable digital pet economic ecosystem jointly owned and developed by players.
PetKingdom whitepaper summary
Friends, today let’s talk about a project called PetKingdom (PKD). However, before we dive in, I need to clarify that there is currently very little official detailed information about this project, especially a complete whitepaper. So, based on the scattered information I’ve been able to gather, I’ll give you a preliminary introduction.
What is PetKingdom
According to available data, PetKingdom (PKD) appears to be a blockchain project that combines gaming and decentralized finance (GameFi) concepts. You can think of it as a “pet kingdom” themed blockchain game. In this game, players can own digital pets and earn rewards by completing tasks and participating in battles—these rewards are the project’s native token, PKD. It also involves non-fungible tokens (NFTs), meaning the pet characters or items you acquire in the game are unique digital assets that you can own, and even trade in the in-game marketplace, just like collecting rare cards.
The project was relatively active around September 2021, with more than 4,200 active players at the time. This indicates it once had a certain player base as a blockchain game project.
Token Information and Current Status
PetKingdom’s token symbol is PKD, and it is deployed on Binance Smart Chain (BSC), which means it is a BEP-20 standard token. You can think of BSC as a “digital highway” designed to provide fast, low-cost transactions for blockchain applications and games.
According to information from cryptocurrency data platforms like CoinMarketCap and CoinCarp, PKD has a total supply of 20,000,000 tokens. However, it’s important to note that these platforms show its “self-reported circulating supply” as 0, and its market cap is also shown as $0. This means there are virtually no PKD tokens circulating in the market, or the data has not been verified. At the same time, CoinCarp also points out that currently, PKD tokens cannot be purchased on any mainstream cryptocurrency exchange.
Not Investment Advice: Friends, this information is very important. If a project’s token is not circulating and not listed on exchanges, its liquidity is almost zero, and the investment risk is extremely high. This usually means the project may have ceased operations, is in a very early stage, or has not developed successfully. When considering any cryptocurrency project, be sure to conduct thorough independent research and understand the inherent high risks.
Verification Checklist (Based on Available Information)
- Block Explorer Contract Address: The contract address for the PKD token can be found on BscScan:
0xa7c97d58...eeb9aa878.
- GitHub Activity: Due to the lack of official information, it is currently not possible to assess the activity of its code repository.
Project Summary
In summary, PetKingdom (PKD) was once a GameFi project based on Binance Smart Chain, aiming to attract players and reward PKD tokens through digital pets, NFTs, and game tasks. However, based on the publicly available information, the project lacks a detailed official whitepaper, has zero token circulation, and is not listed on mainstream exchanges. This suggests the project may no longer be active, or its development has not met expectations.
For any blockchain project, transparency, a detailed whitepaper, an active community, and tradable tokens are key factors in assessing its health. Given the current information status of PetKingdom, it is recommended that you conduct thorough research and fully understand the potential risks before considering any related actions. This is absolutely not investment advice.
