Wrapped Gen-0 CryptoKitties (WG0)
Key data
updated $0Wrapped Gen-0 CryptoKitties (WG0) is a tokenized version of Generation 0 CryptoKitties — the very first, limited batch of collectible digital cats issued on the Ethereum blockchain back in 2017. Wrapping means locking an original Gen-0 kitty in a smart contract and issuing a fungible ERC-20 token (WG0) in its place, so a unique NFT becomes a tradable, divisible asset. In short, WG0 lets you get liquid exposure to rare Gen-0 kitties without buying a whole NFT.
Frequently asked questions
What is WG0 and how is it different from a regular CryptoKitty?
A regular Gen-0 CryptoKitty is a unique NFT — each one is one-of-a-kind and can't be split or traded fractionally. WG0 wraps these NFTs into fungible ERC-20 tokens, making them interchangeable and divisible like ordinary crypto tokens. Essentially it converts rare collectibles into a more liquid, tradable form.
How does the technology behind WG0 work?
WG0 runs on Ethereum: original Gen-0 CryptoKitties are deposited into a custodial or smart-contract vault, and an equivalent amount of WG0 tokens is minted. The token follows the standard ERC-20 interface, so it works with wallets, exchanges, and DeFi tools that support Ethereum. Unwrapping burns the tokens and returns the original kitty from the vault.
How is the supply of WG0 issued?
The supply is fully backed: WG0 is only minted when a genuine Gen-0 CryptoKitty is locked in the vault, and it's burned when that kitty is redeemed. Since Gen-0 kitties were only ever issued in a fixed, limited number at the project's launch, the maximum possible supply of WG0 is capped by that original set — no new Gen-0 kitties can ever be created.
How can I store and use WG0 tokens?
Because WG0 is an ERC-20 token, you can hold it in any Ethereum-compatible wallet such as MetaMask or a hardware wallet. You can trade it on decentralized exchanges, transfer it freely, or use it in DeFi applications like any other ERC-20 token. If you want the underlying collectible back, you redeem your WG0 through the wrapping service and receive the original Gen-0 kitty.
