Offering A Kitty To A Friend : Cryptokitties

Offering A Kitty To A Friend : Cryptokitties

Playing is fun, but playing with friends is even better. Yesterday I wanted to offer one of my friend some kitties, for him to get started. It turned out that putting a really low price on a kitty and telling him to hurry to buy it did NOT work - 2 out of 3 times, somebody else got the kitty (good for them!). I asked support, which told me that there IS a function to transfer kitties, but it has not been implemented yet in the website interface. So I had a look at the contract ABI, and figured out how to do it. Here is a very short and simple guide for those of you who want to give the gift of CryptoKittens to your loved ones. Step 1: Open the contract in a separate tab That way you will have all the infos on hand. The contract we'll use is the 'Core' one You'll need two things: The contract address (0x06012c8cf97bead5deae237070f9587f8e7a266d) The ABI (Data encoded in JSON, available in the "Contract ABI" part) Copy the contract adress and the ABI in the form. Something saying "read/write" contract appeared, as well as a list of functions In the list of functions, select "Transfer" Two new boxes appeared : '_to' and '_tokenId' In '_to', put the ETH adress of your friend. They can get it through Metamask My Ether Wallet will ask you "How would you like to access your wallet?". Select "Metamask" A window with the transaction details will appear. Click on "Yes proceed with transaction" Validate the transaction in Metamask. ** If the gas expense seems too high (more than 1USD), there is probably an issue. Abort!** So there you go, bring new friends to the party, and enjoy! If you want to exercise offering kitties, you can try and send one my way ;-) 0xc851c3dfd2b7fb50735cbc8e182c07864e58fe9d Edit: Edited a few times for formatting but I can't make it better than this.

Ethertanks Cash Cow Just Launched (the New Cryptokitties). Buy Now?

ETHERTANKS cash cow just launched (the new cryptokitties). Buy now? The newest blockchain game based on Ethereum just launched. Just like cryptokitties, it seems to be well received and some very very early adopters are already rich. Some say its a ponzi but they fail to realize that the price of tanks scales.

Towards Cracking Crypto Kitties Geneticcode

Towards Cracking Crypto Kitties Geneticcode

Towards Cracking Crypto Kitties GeneticCode or a quick tour through some neat Ethereum dev tools [Edit: In an earlier version, we mentioned assert() should be used when checking input parameters, but as Nick Johnson and Yoichi Hirai have pointed out, the use of revert() is perfectly correct here . Our mistakes, apologies.] Chapter Zero: Encountering of theKitties I just finished teaching (as a volunteer teacher during my down time) a full-stack Ethereum dApp development course, in Solidity, and Chinese:-), with the goal of boosting the awareness of blockchain and smart contract in Chinese developer community. 55 students graduated in my first class and I am lucky to become good friends with some of them, like Zhicheng and Fanglu . After we emerged from this course stuff, we suddenly found ourselves surrounded by Like many others, none of us can resist these cute crypto creatures and we all quickly get addicted to this game. We enjoy breeding new kitties and have upgraded our Rubber Duck Debugging routine to Crypto Kitty Debugging. Addiction to games, for me, is usually unhealthy. But I would say this time is an exception as this addiction to Crypto Kitty breeding game quickly draws three of us to this question: How are baby crypto kitties genes determined? We decide to spend a nice Saturday evening on this and we believe we have made some pretty good progress towards developing a cracked software that can help you determine the genetic mutation of your baby crypto kitties before they are born. In other word, this software can help you test and determine when is a good time to let your pregnant matron kitty give birth to the baby kitty so that you can see some nice mutations. We are publishing this with the hope that just like Crypto Kitty acted as a entry drug towards Continue reading >>

Crypto Kitties And Network Backlog

Crypto Kitties And Network Backlog

The Crypto Kitties application is causing major disruption to the Ethereum network. Ultimately this is good for Ethereum. For the reasons why, well, this is a good read. vDice smart contracts are processing bets with significant delays. Further, due to the increase in the uncle blocks caused by thenetwork backlog, the randomDS Txs are failing more often. Specifically in relation to vSlots , there is an updated version of the vSlot solidity code which will be deployed before the weekend. It is recommended to wait, and dont play vSlots until the code update. With this update code, the blockchain re-orgs wont cause the callbackto fail completely and waste all gas, as is happening now. Thiswould allow an attempted resend of the callback tx once the calling tx hasbeen included in the new longest chain. Also in this update code, if theproof verification fails for any reasons, the user is refunded. Redeployment of the LedgerRandomProofVerifier will includea small fix of the verification of the randomDS proof included in theethereumAPI. We are aiming to push these codebase changes and updates to vSlots before the weekend. Ultimately, Ethereum is a new technology that will emerge stronger from such situations. Popular applications are a sign of utility and strength. Lets never forget that. Your email address will not be published. Required fields are marked * Next game: vPax - nearing dev. completion.

Github - Dapperlabs/cryptokitties-bounty: Bounty Program For Cryptokitties Smart Contract

The CryptoKitty Bounty Program is NOW CLOSED Thank you everyone for your participation!! Please stay tuned for rewards! CryptoKitty Bounty ProgramCryptoKitties recognizes the importance of security researchers in keeping our community safe and fun. With the launch of CryptoKitties around the corner, we would love the community to help provide disclosure of security vulnerabilities via our bounty program described below. What you Should Know About CryptoKitties: CryptoKitties is a game centered around breedable, collectible, and oh-so-adorable creatures we call CryptoKitties! Each cat is one-of-a-kind and 100% owned by you; it cannot be replicated, taken away, or destroyed. CryptoKitties are non-fungible tokens (see ERC #721 ) that are indivisible and unique. The smart contracts have over 4-billion variations of phenotypes (what you see) and genotypes (what you dont see). Because cats are tokens on a blockchain, they can be bought, sold, or transferred digitally, with strong guarantees of ownership. CryptoKitties is built on the Ethereum network; ether will be necessary to fuel transactions, which include purchasing, trading, and breeding CryptoKitties. For the purpose of this bounty program, the program will run within the Rinkeby test network. Also the source code will be available for review. Two CryptoKitties can breed a new CryptoKitty. Kitties do not have a permanently assigned gender. While they can only engage in one breeding session at one time, each Kitty is able to act as either matron or sire. The owner chooses per breeding interaction! This bounty program will run within the Rinkeby network from 12:01am GMT November 16th - 11:59pm GMT November 20th, 2017. All code important to this bounty program is publicly available within this repoHelp us identify bugs, Continue reading >>

How Can I Programmatically Get A Sales History Of Cryptokitties?

How Can I Programmatically Get A Sales History Of Cryptokitties?

The pages and show sales with prices and the IDs of the cats sold. How could I implement such a functionality programmatically? I've already searched GitHub but the code there does not allow to access such a sales history. I've also looked at the transaction details at but I do not get information about the cat ID there. The kitty auction contract emits an "AuctionSuccessful" event on each successful sale. You can get past events using web3.js with code that looks something like: var cksale = web3.eth.contract(saleAbi).at("0xb1690C08E213a35Ed9bAb7B318DE14420FB57d8C")cksale.getPastEvents('AuctionSuccessful', { fromBlock: 4605167 }, (error, events)=>{ console.log(`Got some sales: ${JSON.stringify(events)}`)}) Note: Cryptokitties was deployed on block 4605167 so no point in checking blocks earlier than that for events. It takes a while to search for past events, you'll probably be better off chunking it into 10/100 block intervals instead of trying to get all events in one giant call. Continue reading >>

Cats being stuck with Bun in Oven or Resting is a common issue, and it will generally resolve itself within a few hours. But in case you dont want to wait, you can call the smart contract manually using MyEtherWallet. UPDATE: They have removed the CryptoKitties contract from MEW. You can copy the ABI from here: STEP 0: Make sure your cats are ready to breed or the transaction will fail. (Click on the link in step 3 and enter the kitty IDs individually on line 29 isReadyToBreed and click on Query to check.) 1. Go to . 3. Select the CryptoKitties smart contract (the address should match ). 6. Input the kitty IDs of your matron and sire. 7. Select Metamask as your sending option in the bottom. Click Connect to Metamask. 8. Press Write and enter in the breeding fee (currently 0.008 at the time of this post, this breeding fee can change) as the sending value in the popup. 9. Send the transaction and in the Metamask popup, enter your gas price. (See for current gas prices.) Once your transaction is successful, the matron of the breeding pair should have a new Bun in the Oven. Happy breeding!

Guides for collecting and breeding digital cats! [Guide] How To Fix Bun in the Oven issue. CryptoKitties Guide How To Fix Bun in the Oven issue. I noticed a lot of people were complaining about a timer issue. I thought that was pretty weird for a Smart Contract so I dove in to try and figure it out.

But, dont worry here are the steps to fix it! 1) Go to MyEtherWallet.com (be careful if you search for the site online there are a lot of scam links). 2) Select Contracts from menu at the top. 3) Enter 0x06012c8cf97BEaD5deAe237070F9587f8E7A266d as the contract address.

I Bred 'crypto Kitties' On The Ethereum Blockchain

I Bred 'crypto Kitties' On The Ethereum Blockchain

I Bred 'Crypto Kitties' on the Ethereum Blockchain CryptoKitties wants to make blockchain tech fun. Trying to explain Ethereum to someone who is unfamiliar with the topic is a bit like administering anesthesia. You start by explaining a blockchain and their eyes slowly glaze over. By the time you've gotten to smart contracts and ICOs , they're slack jawed and drooling all over the place. When you're finished and they regain consciousness, they won't remember a thing. This is all to say that learning about and using Ethereummost succinctly described as a distributed computing platform based on a public ledgercan be unbelievably dull. In a bid to make blockchain technology fun, a Canadian tech company called Axiom Zen has created CryptoKitties , a game where players breed and trade cats using smart contracts on the Ethereum blockchain. "Kitties should be a part of this revolution of bringing blockchain technology to the masses," Benny Giang, a product manager at Axiom Zen told me in an email. "So many great companies are building awesome technology that the world won't care about or understand. We're the flag bearer for the rest of this ecosystem in terms of getting celebrities to associate with kitties and the Ethereum network." A test version of CryptoKitties was unveiled last weekend at ETH Waterloo, the largest Ethereum hackathon in the world. It was accompanied by a breeding competition that challenged participants to breed digital kittens with certain physical traits and rewarded breeders with real Ether (the digital money that powers apps on the Ethereum network). As a cat-lover with an interest in Ethereum , when I heard about the project I thought I'd try my hand at breeding a few crypto kitties of my own. CryptoKitties will be officially released on November 1, Continue reading >>

Enter "0x06012c8cf97BEaD5deAe237070F9587f8E7A266d" as the contract address. This is the core smart contract address for CryptoKitties which you can verify here ( ) At Etherscan, click the "Copy" button next to the Contract ABI In your MyEtherWallet window, paste the copied text below into the section where it says ABI/JSON Interface. The pasted text should begin with something like [{"constant":true,"inputs":[{"name":"_interfaceID","type":"bytes4"}] Click "Access" and a drop down menu should appear below. Select the command "GiveBirth" from the dropdown menu. Enter your Kitties ID, this can be found under your cats name or in the URL. For example is ID 44650. Make sure not to include the number sign (#) Then unlock your wallet. If you've never used MyEtherWallet before you'll need to export your private key from MetaMask. Click on MetaMask, then click on the three horizontal dots, click "Export Private Key", enter your password, and you'll be shown your private key. Copy this to your clipboard - and remember to keep this safe it is basically your Ethereum wallet password! Double check that the MyEtherWallet site your on is HTTPS (has the green lock symbol in the URL bar) - it's always good practice to double check that before proceeding. Select the unlock method "Private Key" from the list and hit "Unlock" Once unlocked you should see the command "Write" available if you've filled everything in. Click it. A new menu will pop up with some additional fields. The first one asks you how much you want to send, leave it at 0. In the next field it will have auto populated the Gas Limit.

Read More Here are all the costs you might encounter while playing CryptoKitties. Hiring a sire for your cat. (Price varies.) Sales fee. When you successfully sell or sire a cat,3.75%of the sale goes to developers. Transaction fees (gas)*. Every time you perform an action, you have to pay the ethereum miners to complete the task. The gas fee is shown before you submit a transaction. It is roughly between$0.30 $3.00(depending on ethereum network traffic). * The breeding fee was initially 0.001 ETH. It had to be raised due to the mechanics of how kittens are born (the breeding fee has to be higher than gas fees). The breeding fee may drop back down once the ethereum network can handle a large volume of transactions. * Gas fees high right now due to the volume of transactions on the blockchain.
