What's this about?

The King of the Ether Throne awaits you. It can be yours for a price - here are the contract rules:

How Can I Rule?

The power of the King of the Ether Throne can be yours for the current claim price of just 500 FINNEY (0.5 ETHER) (as of 2017-04-28 12:06:45 UTC). Here's how:

Claim from an Exchange

Careful - do not send ether to King of the Ether directly from an exchange like Poloniex or Kraken - it is likely that any compensation payment will not go to your account. Instead, if you don't want to use a full Ethereum client (like geth or Mist Ethereum Wallet), we suggest sending via myetherwallet.com.

1. Create an Ethereum address at myetherwallet.com (don't lose the passphrase/key!).

2. Withdraw funds from your exchange account to the myetherwallet.com address you just created. Make sure you withdraw a little more than the current claim price to cover gas costs - 0.01 ETHER more will do.

3. Wait for the funds to reach your myetherwallet.com address (this can take quite a long time with some exchanges).

4. Go to the 'Send Ether' tab on myetherwallet.com. Once you've unlocked your wallet, you should get to a form a bit like this:

5. Copy the details below into the form on myetherwallet.com: (you'll need to use the 'Advanced: Add More Gas or Data' option)

To Address Send funds to the King of the Ether contract at address:
Amount to Send As of 2017-04-28 12:06:45 UTC, to claim the throne you will need to send:
ETHER
(Don't worry though, if the amount turns out to be too little or too much, the transaction will be cancelled and your funds returned, minus the gas fee).
Transaction Type You'll need to choose 'ETH (Standard Transaction)' here - otherwise you'll won't be able to choose the 'Add More Gas or Data' option which you'll need next. Hopefully the exchange only sent ETH to your wallet anyway.
Data To make sure everyone knows who is the Monarch, you'll need to enter a name.
For technical reasons, you'll need to encode your name as data using this converter:
Choose Your Royal Name: converts to:

Copy the converted name data above into the 'Data' box (if you can't see the Data box, click 'Add More Gas or Data').
(Names must be 1 to 25 characters long, English alphabet only, contain at least one letter or number, and use only symbols ! ( ) - . _)
Gas Enter 250,000 gas here - don't worry, that's less than 0.01 ETHER at the time of writing. This powers the contract.

6. Click 'Generate Transaction', then 'Send Transaction'. Wait a few minutes, then reload this page.

7. Any compensation will be sent back to your myetherwallet.com address, so make sure to keep a copy of your myetherwallet.com passphrase/key.

Disclaimer: we are not affiliated with or connected to myetherwallet.com; they seem reputable as of August 2016 but we strongly encourage you to do your own research.

Claim by Sending Ether using the Ethereum Wallet

Ethereum Wallet users can claim the throne by sending ether to the contract.

1. Go to the "Send Funds" page of your Ethereum Wallet app and enter the following details:

From We recommend using your 'Etherbase' account to pay the contract.
Wallet-contract accounts should work, but you'll need to make sure you have some funds in your 'Etherbase' account to pay for the 'gas' fee.
To Send funds to the King of the Ether contract at address:
Amount As of 2017-04-28 12:06:45 UTC, to claim the throne you will need to send:
FINNEY (that's 0.5 ETHER)
(Don't worry though, if the amount turns out to be too little or too much, the transaction will be cancelled and your funds returned, minus the gas fee).
Data To make sure everyone knows who is the Monarch, you'll need to include your name using the 'ADD DATA' button.
For technical reasons, you'll need to encode your name as data using this converter:
Choose Your Royal Name: converts to:

(Names must be 1 to 25 characters long, English alphabet only, contain at least one letter or number, and use only symbols ! ( ) - . _)
Fee The Ethereum Wallet should estimate the gas fee for you - you don't need to change anything.
You can expect to be charged up to around 250,000 gas.

2. After clicking SEND, a confirmation popup will appear where you will need to enter your password. Check the amount, then click CONFIRM.

3. After you've sent your funds, wait for the transaction to confirm, then reload this page. It may take a few minutes to appear.

Claim using the geth console

geth users can claim the throne by sending funds to the contract via the geth console.

In the geth Javascript console, this command will claim the throne by sending 500 FINNEY (0.5 ETHER) to 0x2464d1d97f8d0180cfad67bdb19bc30cca69dda0:

Don't forget to unlock your ethereum account first - the Javascript above assumes you're using account 0.

To update the Javascript above with your chosen name, enter it here:
Choose Your Royal Name:
(Names must be 1 to 25 characters long, English alphabet only, contain at least one letter or number, and use only symbols ! ( ) - . _)

The claim price above was last updated at 2017-04-28 12:06:45 UTC - refresh this page to get the latest (and to see yourself appear once your transaction is confirmed!).

Claim by Interacting with the King of the Ether Contract in the Ethereum Wallet

If you're using a recent version of the Ethereum Wallet, you can watch and interact with the King of the Ether contract to become ruler - this shows off the power of Ethereum best!

1. Open your Ethereum Wallet. Choose 'Contracts' in the top-bar, then click 'Watch Contract'.

2. On the 'Watch Contract' pop-up, fill in the following details:
For CONTRACT NAME, enter 'King of the Ether'.
For CONTRACT ADDRESS, enter:

For JSON INTERFACE, copy-and-paste this:

Yes, it's very long, make sure you copy it all. Click 'OK' to add the contract to the collection of 'Custom Contracts' you're watching.

3. Click on the 'King of the Ether' contract you just added to the 'Custom Contracts' section. You should now be able to interact with the King of the Ether contract using the 'READ FROM CONTRACT' section on the left, and the 'WRITE TO CONTRACT section on the right.

4. Under the 'WRITE TO CONTRACT' section, choose 'Claim Throne' from the 'Select Function' drop-down. Fill in these details:

Monarch Name What should we call you, your majesty?
(Names must be 1 to 25 characters long, English alphabet only, contain at least one letter or number, and use only symbols ! ( ) - . _)
To double-check if the name is allowed first, you can use the 'Validate proposed monarch name' in the 'READ FROM CONTRACT' section on the left.
Execute From Which Ethereum Wallet account do you want to use? It's generally recommended to use the 'Etherbase' account, not contract-wallets. Don't lose the account - your compensation payment will only be sent to this account.
Send You'll need to specify the claim price you will send here. As of 2017-04-28 12:06:45 UTC, the claim price was 500 FINNEY (0.5 ETHER). If you want to double-check, the King of the Ether contract page in the Ethereum Wallet will show the latest in the 'Current claim price in finney' section on the left of the screen.

5. Click 'Execute'. You'll be prompted for your password, then click 'Send Transaction'.

6. After you've sent the transaction, wait for it to confirm, then reload this page - it may take a few minutes to appear.

Other ways to claim

The instructions for sending via the Ethereum Wallet should work in other wallet apps - make sure you include plenty of gas (250,000). However, be careful - DO NOT send funds from exchange wallets since the compensation payment is likely to go to the exchange, not to you!

We're planning to launch a DApp web interface in the Ethereum Mist browser shortly to make it even easier and more interactive.

All contract addresses shown here exist ONLY on the Ethereum Foundation (Hard Fork) chain - do not attempt to use the contract on the "Ethereum Classic" chain! You should 'split' addresses created prior to the fork if you are worried about losing ETC.

Whichever way you claim, make sure your read our Disclaimer first.

Neighbouring Kingdoms

Price of the King of the Ether too high? Want a Kingdom with fewer uppity peasants?

For just 1 ETHER (plus a little gas money) you can fork your own alternative Kingdom where you make the rules, you get a 50% share of the commission, and you get your own web page just like this one.

Interested? Or just want to see (and rule!) other Kingdoms people have created? See More of the World!.

FAQ

Where does the source code for the contract live?

github.com - KingOfTheEtherThrone.sol

What's the address of the contract?

The contract for King of the Ether is located at 0x2464d1d97f8d0180cfad67bdb19bc30cca69dda0.

Its Contract JSON Interface is:

You can watch it on a chain explorer if you like.

How much is the commission charge?

2%. This is shared equally between the top-wizard (the original creator of the first contract) and the sub-wizard (the creator of the individual kingdom).

Haven't I seen something like this before?

Yes, probably - there are/were a number of Bitcoin chain games along similar lines (though they normally seemed to involve owning a magnificent gem or a special coin).

The difference with Ethereum is that you don't have to trust the author not to run away with the money - instead, you can inspect the contract and rely on the blockchain to ensure it is executed as written.

This contract was somewhat inspired by ethereumpyramid.com (to which this contract is in no way affiliated or connected).

You might also be thinking of one of our Neighbouring Kingdoms.

Is this the first version of this contract? Or have there been other throne contracts?

This is the third version of the contract. Learn more about the past ages (including celebrity rulers!).

When a monarch is struck down by the curse, where does the money go?

Ah - I see what you mean, but it doesn't quite work like that - there isn't really any money to go anywhere when that happens! For example, if a monarch pays 15 ether to claim the throne from someone, then that 15 ether is not held by the contract - it is sent to the monarch before her as compensation (minus a little commission). So it's not like the 15 ether they paid is "lost" if the curse hits them - it had already gone to the ruler they usurped 14 days days earlier. The one exception is when someone claims an empty throne that's back at the starting price of 500 FINNEY (0.5 ETHER) - in that case it goes to the "wizards" behind the throne as commission.

I think something went wrong. Can I have my money back?

Ah. Well, you see, one downside of trustless autonomous contracts executing on the blockchain is that there is no possibility of human intervention - (almost) no-one can reach into the back of the machine and tweak things, even if they wanted to. Besides, there is no money to give back - it's all been given to the previous monarch, remember? So refunds are - regrettably - both impossible and unethical.

Is this safe? Or will we up with all the ether trapped in a DarkKingdom?

As the Disclaimer below points out, sending funds to experimental contracts using experimental wallets in experimental crypto-currency networks is probably not particularly safe.

However, we have put considerable effort into mitigating the risks - see our Contract Safety Checklist.

I have a question that isn't listed here!

Disclaimer

This is intended as a bit of fun and to explore what a contract running on the Ethereum blockchain can do. Please don't spend money you can't afford to lose - keep it fun.

If you suspect that spending crypto-currencies on virtual thrones for non-existent kingdoms is illegal in your jurisdiction, please avoid participating (and complain to your political representatives).

Please note that while the contract will live as long as the Ethereum blockchain, no warranty is given that this website will continue to exist or will continue to promote the contract or list your name.

Under no circumstances will refunds or compensation be paid even if the contract steals all your money and/or shoots your dog. The author disclaims all liability for the operation of the contract which should be considered its own autonomous entity as far as permitted by law - it is your responsiblity to study its likely behaviour before interacting with it, including taking into account that the actual behaviour of the compiled EVM bytecode in a real eth/geth node may differ from the assumed behaviour based on the apparent intent of the solidity source code.

By interacting with the contract you agree to accept the conditions in this section as well as those listed at ethereum.org/agreement.
