Hey Everyone, As an important part of @PapayaBot I'm currently working on prototype of anchor for ERC20 ethereum tokens. At the moment I'm testing it with ICN. It is generic enough to support any, but as a precaution I'll be enabling them one by one, once everything is tested. I'll make my prototype available in a few days. I'm intentionally not using smart contract yet, want to have it working in production for some time, before I understand all caveats. At the moment process works as following: - you submit ethereum and stellar address to the endpoint, receiving random string in response - you sign that random string to confirm ethereum address ownership and submit it That's it, now token sent from your registered address to anchor address will be forwarded to your stellar account. And vice versa. I'm looking forward for your questions, ideas and suggestions. What do you think is important for that kind of service?

Ya very nice. looking forward to seeing a prototype even if just on testnet just to check out it's operation. I don't fully understand where the funds are stored outside the stellar network from what you said here. I assume it's some trusted 3rd party that holds each of the ERC20 asset tockens out side stellar? I assume it would work much the same way as https://naobtc.com or the other etherium anchors as far as deposit withdraw as far as user interface? Ok gook luck and looking forward to seeing it in operation.

Yes, all tokens arrive to anchor's address and stored there, same as all other anchors, except stellereum.

Did you advance in this project ? Would be wonderfull to have this, and even more if it is open source ?

pacngfar Hey, yes, my ICN anchor is working. I'm just cleaning up/testing now before submitting to SBC. I'd be happy to open source the code, but it requires some extra effort and I'm not ready for that at the moment. I can share it with you privately, especially if you want to review the code and let me know about the problems you find.

I've added ETH and tokens: BAT, ZRX. Working on REP and OMG. What other tokens would you like to see on Stellar network? Does anyone have their favorite?

In my effort to aggregate different anchors under one domain I moved erc20.net and erc20.papayame.com to apay.io. btc.papayame.com and ltc.papayame.com will soon follow the lead.

@umbrel - it seems apay.io isn't working atm. I'm very interested in this project, appreciate the updates.

CorySvensson could you share what is not working for you? I'll look into that, right now cannot see anything wrong in logs

Papaya Anchor (BCH, BTC, LTC, ETH + tokens)

umbrel, you do an excellent job, i reported a problem and you sorted it very quickly, will be using again in future now i know exactly how to use papaya!

xlmmm

hello, i too am having issues withdrawing ETH token from Stellar to ERC20 via apay.io anchor.
When it says to enter 'yourETHaddress*apay.io' is that my personal, external wallet that i interface with using MEW, or is that supposed to be the ETH wallet address I received when i associated my stellar account with apay.io anchor (deposit account at anchor?) ?

xlmmm

xlmmm
i've been told in a couple different places that i need to use my existing ETH address, not the deposit address. that part i understand now. however when I try to enter it, I am now getting 'invalid account address' any thoughts?

@umbrel any thoughts?

xlmmm

xlmmm I've also noticed that the ETH asset from apay.io is no longer verified? can someone confirm this or clarify please?

@umbrel any thoughts?

Where are you trying to enter it? Which stellar wallet are you using to withdraw ETH? Form on apay.io is only for deposits, withdrawal will be from the wallet you're using.

xlmmm Questions:
1. What causes an anchor's assets to appear as verified or not verified?
1a. what would cause this status to change (intermittently?)
2. When I sent ETH to the deposit address, my Stellar account was credited almost instantly, Bravo! However I'm curious what is the outgoing process and why does it take 3+ hours? Did I do something incorrectly?

What service are you using that shows verified/not verified?
two months ago everything was instant, then I started getting issues with my ethereum cluster, which wouldn't sync and lagged behind the network. Both deposits and withdrawals were going through with a big delay, sometimes days, unless I push it manually.
Then I was able to resolve issue with ethereum cluster, but now I got some other issues with my code, which makes sending outgoing payments automatically a bad idea. I'm rewriting some parts of the system, meanwhile processing withdrawals manually multiple times a day, so sometimes it takes up to 6-8 hours, when I don't have access to my laptop.

When it says to enter 'yourETHaddress*apay.io' is that my personal, external wallet that i interface with using MEW

That would be your personal ETH address.

I sent and withdraw ETH successfully through apay.io today ? - sending was fast but withdrawing took like an hour.

xlmmm

abuiles thanks abuiles.

i've been trying too, but when i enter MyETHaddr*apay.io, i get the message saying 'invalid account address' and i've also noticed that the ETH (and others) are not verified anymore, and they were just the other day.

just looking to better understand how to withdrawal my ETH and how the anchors work.

xlmmm

just a little update on my withdrawal situation...

about 3 hours ago, i tried to withdrawal again, and this time i noticed that the apay.io assets were now verified (again). so I sent the ETH token for withdrawal as advised above and per the apay.io website: https://apay.io/

no problem there except it is 3 hours now and the ETH has not actually been sent to my ETH wallet.

Questions:
1. What causes an anchor's assets to appear as verified or not verified?
1a. what would cause this status to change (intermittently?)
2. When I sent ETH to the deposit address, my Stellar account was credited almost instantly, Bravo! However I'm curious what is the outgoing process and why does it take 3+ hours? Did I do something incorrectly?

any guidance or suggestions are greatly appreciated!

umbrel hey, thanks for the reply!

I was entering MyETHadd*apay.io (wallet I interface with MEW) in both Stellarport and StellarTerm and both interfaces were giving me 'invalid account address'

on stellarport, in the exchange menu, when i click to change assets i type 'apay' on the issuer. this brings up all the assets issued by apay.io. right now when i do this, all your assets are verified (green circle check mark) with the exception of XIR token (orange triangle exclamation). (i'm not sure this token is actually issued by you or someone else because the issuing address is different than your other assets). When i was experiencing this last time, all the assets had the orange yield sign. i have no idea why it would be one way at one time and then another later.
understood, i hope you can work it out because this is really useful.

That's surprising, I'll try to test it more to see if that's something on my side.

I guess stellarport checks issuer's stellar.toml on the fly, maybe last time there was a network issue and their request failed, so assets came up that way. It's just a guess though. XIR is not my asset

ETH lost attempting to withdraw using apay.io.

ETH immediately credited from my StellarTerm account then never arrived to the destination.

Are you able to help me recover the 0.65 ETH lost in transaction?

StellarTerm-->ETH-apay.io (lost in escrow?) —>Poloniex (never arrived)

Development update

That was operationally the hardest quarter so far. Started with high Bitcoin fees and therefore big delays with BTC withdrawals, followed by ETH nodes instability, which took me a while to overcome.

Updated website interface to address frequently asked questions, such as withdrawal fees, minimum deposit/withdrawal amounts. Notes for Litecoin address format.
Implemented SEP-0006 standard to make it easy for wallet developers to provide deposit addresses for assets supported by the anchor and handle withdrawals directly without the need to send user to anchor website
Started to provide liquidity first for XLM-BTC pair, now for other pairs too.
Further improving redundancy of internal processes
Preparing to open source some code in the near future
Some new assets are in works, but got delayed due to reliability issues

Here's how it looks now

Future Roadmap:

Looking for ways to provide proof of reserves
Bitcoin Lightning node
Bringing back up testnet version
Merging exchange widget into apay interface

We love your feedback!

Hi Guys, can someone help me with Stellar-ETH Papaya anchor, I added Papaya ETH as anchor and I got ETH address. Then I sent ETH to given address but when I want to trade to xlm via StellarTerm it still says 0 ETH available. Can someone give me a hint or advice.

Thx!
