CryptoKitties - What's News?

Ethereum Gas Price - All Time High - Transaction Fees

Birthing fees are pretty high. I would like to breed but i saw the transaction free / cost which are at $1000.

I'm trying to buy one, and set the gas price to slow (1hr). Over three hours later, and up to $8.53 on gas & still no cat. Is the game doomed? Update! The transaction took 6 hrs & 15 min. - but it did finally go through.

Just bought two cheap kitties and tried to breed them. But the birthding fee is 0.1 ETH (~150 USD)... that's crazy.

Yeah, CryptoKitties is unplayable right now.

Yeah, after buying two cats unaware it would cost 0.1 ETH (~150 USD ) to breed them I am a little upset. This is way too expensive, I see absolutely no way to get started for less than a few hundred dollars worth of ETH if you want to breed cats that are worth selling.

Fees are exceptionally high now due to Ethereum's high price and movements. The gas fees are tied to Ether (ETH) therefore high prices.

Probably stuck with my cats forever... jeez, I hate to think of how much they cost in dollars with ether (ETH) as expensive as it is now.

How much gas limit should I use to adopt a cat? The recommended gas limit in meta mask is absurd and the transaction fee would be like $800, how much should i use?

Gas prices [on Ethereum] have now nearly completely stopped the market. I know there's plans to revitalize CryptoKitties [on Flow].

People are mostly buying wrapped in bulk to lower gas fees. With the wrapped kitty tokens (WCK, WG0, WVG0) you can buy ten cats and pay $30 fee vs $300 (10 x $30) fees.

CryptoKitties v2.0 - From Ethereum to Flow (Blockchain) - Build In Public

On Ethereum, your CryptoKitties live in the storage area associated with the CryptoKitties contract, and they have a data field to track who owns them.

On Flow, your CryptoKitties will live in the storage area associated with YOUR account...

-- Dieter Shirley, Co-Creator CryptoKitties, Creator Flow @ Dapper Labs

Welcome to the early stages of our grand meowgration to Flow. We want to enable mainstream adoption of the mascot of blockchain through free to play, new mechanics, upgradable smart contracts, easy on-boarding, fewer limitations and restrictions, and yes, fully composable, extensible on-chain layer one Kitties with true utility. Phew, that was a lot but every bit of it matters.

Our vision is to inspire the world to collect CryptoKitties.

This board will contain ideas, implementations, and designs of all the new features we want to test and potentially bring to Flow. Let's put lot of emphasis on the word "test". These features are in various stages of development as we work towards building the closed alpha of CryptoKitties on Flow.

CryptoKittes on Flow (Blockchain) Board - Build in Public

  • Intrinsic Genes & Nests
    • Intrinsic genes modify the breeding and genetic properties of CryptoKitties and occupy 4 loci in a Kitty's genome. Types of intrinsic genes:

      Breeding Properties:

      • Vigor: modifies breeding time
      • Fecundity: modifies Catpacity

      Genetic Properties:

      • Mutability: modifies both base mutation and devolution probability
      • Penetrance: modifies rate of recessive emergence (gene swaps within a Locus)
  • Gene Science
    • The Gene Science contract is responsible for the genetic structure of Kitties. Unlike CryptoKitties' math-based mutation pyramid, Gene Science on Flow uses a queryable lookup table to enforce breeding logic for mutating pairs.

      Every known legacy mutation will be ported over to CryptoKitties on Flow and locked forever. While legacy mutations will remain untouched, we do want your Jaguar to be able to mutate with new CK on Flow genes while retaining its legacy mutation.

      A gene size of 10 bits will allow for 2^10 potential genes in a single locus. 25 loci make up the CryptoKitties genome with the first 12 being reserved for legacy loci. We've also made changes in the technical implementation of mixgenes and the core Kitty structure to allow backwards compatibility.

  • Breeding with Nests
    • Nests are consumable NFTs required in breeding. To breed a pair of Kitties, you'll need one Nest and available Cat-pacity from a parent. Upon breeding, an Egg NFT is created and placed within your chosen Nest which can be hatched at a later time.

      Nests have their own genes which can affect the breeding or genetic outcome of your Kitties. Not all of these properties are included in-scope.

      • Level: Maximum Level of Cat born in this nest
      • Nestpacity: Number of times the nest can be used before disintegration
      • Durability: Probability that the nest does not consume Nestpacity on a breed

Kitty Items - Hats on Cats!

The CryptoKitties NFTs can continue on Ethereum while being equipped by Hats that are NFTs on Flow – they will claim their hats upon traveling over.

Q: What is Kitty Items?

Kitty Items, a project that demonstrates the current best practices for building decentralized app on flow.

Items are hats for your cats, but under the hood they're non-fungible tokens stored on the flow blockchain.

Items can be purchased from the marketplace with fungible tokens. In the future you'll be able to add them to Ethereum CryptoKitties with ownership validated by an oracle.

Wrapped Gen-0 CryptoKitties (WG0), Wrapped Virgin Gen-0 CryptoKitties (WVG0)

The Wrapped Gen-0 contract ($WG0) is now the biggest holder of Gen-0 CryptoKitties -- (Oct 9, 2020)

Q: How is Wrapped Gen-0 and Wrapped Virgin Gen-0 different than Wrapped CryptoKitties?

There is a fixed cap of 50,000 Gen-0 Kitties whereas non-Gen-0 Kitties can be bred indefinitely.

Price History:

Wrapped Gen-0 ($WG0):

Wrapped Virgin Gen-0 ($WVG0):

  • 2021/02/05 - 0.2653 ETH / Circulating Supply: 316

2019

Wrapped CryptoKitties (WCK)

$WCK wrapped cryptokitties; its actually backed by a digital cat; where as other coins are backed by hot-air.

Do you want to collateralise your CDP (Collateralized Debt Position), with yDAI (Yield Zero-Coupon Bond DAI) leveraged CHAI (Wrapper over the DAI Savings Rate), which you can flash loan to your synthetic USD to buy your wrapped cryptokitties?

Turn unique non-fungible tokens into a fungible token.

How? Tokens (ERC20 on Ethereum) each backed 1:1 by an CryptoKitty (ERC721 on Ethereum)

The new thing is cryptokitties wrapped in a newly minted token, that's being traded on a unicorn-themed exchange.

Buy $WCK on Uniswap with $ETH

Price History:

In 24 hours, almost 2,000 CryptoKitties have been wrapped into $WCK tokens raising the floor price of Kitties by 50% -- (June 12, 2019)

Wrapped CryptoKitty ($WCK):

  • 2021/02/05 - 0.0018 ETH / Circulating Supply: 65,612

What's Flow?

Dieter Shirley, Co-Creator CryptoKitties, Creator Flow @ Dapper Labs:

Flow takes the best ideas from [Factbook's] Diem's MoveVM and combines them with a modern, ergonomic syntax inspired by Rust and Swift. We think it's a far better way to build digital assets. -- March 6, 2020

The playground shows off our new smart contract language, Cadence. It pairs linear types with object capabilities to create a secure and declarative model for digital ownership. -- March 6, 2020
