ETH Match v2 - win free ETH just by matching the current balance

[zetherz]

• match.zetherz.eth (etherscan ENS link)
• etherscan direct/non-ENS link
• etherchain ENS link (for if/when etherscan is having issues...)

Ethereum match, simple social experiment. Because game theory is fun

- If you send ETH in the exact same amount as the contract balance, you get yours back plus half the contract balance (minus 5%).
- If you send ETH *NOT* in the exact same amount as the contract balance (i.e. someone else beat you to the punch), current Matchmaster gets to keep it (minus 5%).
- Any time the contract balance falls below the "mastery threshold" (10 finney aka .01 ETH), someone else can become new Matchmaster by sending >= 10 finney w/ a mastery() tx, and they will then receive the Matchmaster payouts.

Notes:
Actual gas cost/requirement should be 42000 but you can send w/ higher gas limit if you want (remember any overages are auto-returned).

If you want to give it a shot and claim the first ETH, send your tx now! Initial balance is 0.015 ETH.

The initial .015 ETH is still available! First person to send .015 ETH gets their ETH back + 50%, or .0075 ETH (- 5%)... or, should be, .021375 ETH total.

[zetherz]

.015 ETH still waiting to be taken. BTW, after it's claimed someone else can become the new master. Anyone who needs clarification on how it works, just reply or PM me!

But the contract shows a zero balance. Am I missing something?

You're absolutely right, thanks for the heads up.. Looks like etherscan is having ENS and ETH balance issues (they have been having issues recently). Twitter users are confirming this.

Here is the direct link to the contract on etherscan but as you can see the balance currently shows -1 on etherscan which is impossible...

Here's the etherchain link. No ENS or ETH balance issues. We are getting the code verified there ASAP!

Will update OP with these links too.

am i wrong to see the number in the etherscan? its writtern there -1 wei
how is that possible that the balance is got -1 ?

but after i see it in the etherchain and there is writter 0.015 eth

Heh, no, you're right.. etherscan is currently showing -1 wei balance for all addresses and their ENS is down. I posted a link to people talking about it on Twitter in my last reply.

Funny enough, the link to verify source code on etherchain (https://etherchain.org/account_verify/) is also down.

So right now, in order to verify both the contract's balance and source code you would need to check the source code on etherscan and then the balance on etherchain, LOL.

[zetherz]

FYI, etherscan is functioning normally again (ENS and ETH balance) so feel free to give it another shot

[zetherz]

.015 ETH still available!

[zetherz]

Last chance to take the .015 ETH! If no one else claims it by tomorrow, I will

[zetherz]

The .015 ETH has been matched, the balance is now .0075 ETH (which can continue to be matched, btw).

Because it is now below the .01 ETH threshold, a new master (or "Matchmaster") can now takeover via mastery().

If anyone wants to do so but is not sure how to call the mastery() function, please let me know and I'll be glad to help!

i have tried to send 0.0075 eth for matching... gas limit 42000 and gas price 8 gwei set.... but transaction cancellation showed with bad instructions. why???

[Kayaman85]

I dont understand..

[salmaku]

this is another version of eth ?

Did you send it from a contract-type (as opposed to raw) wallet? Smart contracts are restricted from interacting with this contract. It looks like a large number of your other tx have also failed, so maybe that is the case?

If not, you could try again with a larger gas limit (perhaps whatever your wallet recommends?). MEW recommends 64350, for example (although it only used 41571 last time...).
