Github interledger-rs ETH-XRP example failed

Andrii_Spivak · March 24, 2020, 9:13pm

I try this tutorial, but look like that it’s not working correct:
ETH part start’s nice, but stops in XRP part.

interledger/interledger-rs/blob/master/examples/eth-xrp-three-nodes/README.md

# Interledger with Ethereum and XRP On-Ledger Settlement

> A demo that sends payments between 3 Interledger.rs nodes and settles using Ethereum transactions and XRP transactions.

## Overview

This example shows how to configure Interledger.rs nodes and use an Ethereum network (testnet or mainnet) and the XRP Ledger testnet as settlement ledgers for payments sent between the nodes. If you are new to Ethereum, you can learn about it [here](https://www.ethereum.org/beginners/). You'll find many useful resources about the XRP Ledger (XRPL) [here](https://xrpl.org). To learn about settlement in Interledger, refer to [Peering, Clearing and Settling](https://github.com/interledger/rfcs/blob/master/0032-peering-clearing-settlement/0032-peering-clearing-settlement.md).

To run the full example, you can use [`run-md.sh`](../../scripts/run-md.sh) as described [here](../README.md). Otherwise, you can walk through each step below.

Hey @Andrii_Spivak!

The issue you’re experiencing is documented here. I believe what’s happening is when the Bob <=> Charlie account is created on Bob’s node, it’s configured so Bob’s XRP settlement engine immediately attempts to settle and prefund Charlie. But because Charlie hasn’t yet created the account on its node, there’s no way for Bob’s XRP settlement engine to send messages to Charlie’s XRP settlement so they can e.g. exchange XRP addresses, which is why the settlement fails.

Two possible solutions:

Try the "Adding Bob's account on Charlie's node (XRP Parent relation)..." step at the bottom before the command for the "Adding Charlie's account on Bob's node (XRP Child relation)..." step – it’s possible that might work
If not, try the new and improved 3-node tutorial which is designed so it doesn’t have this problem – the settlements are all triggered during the STREAM payment itself

Let me know if that works or if you have any other issues!

Andrii_Spivak · March 25, 2020, 3:46pm

Hello @kincaid again and thank you for quick answer !

About you suggested solutions:
(for this moment I try only local-host tests and now starting with docker)
(and the quick answer is that any combinations in your first suggestion don’t help me)

I try to reproduce first suggestion in different combinations and here is result’s:

I get two different result’s for balance checking after transactions:

result-1 :
(every time all value’s after third number after dot - deffer)

 -VirtualBox:~/interledger-rs$ ilp-cli accounts balance alice
{"asset_code":"ETH","balance":-0.0005}
-VirtualBox:~/interledger-rs$ ilp-cli accounts balance bob
{"asset_code":"ETH","balance":0.0}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:8770 accounts balance alice --auth hi_bob
{"asset_code":"ETH","balance":0.0}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:8770 accounts balance charlie --auth hi_bob
{"asset_code":"XRP","balance":-0.577155}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:9770 accounts balance bob --auth hi_charlie
{"asset_code":"XRP","balance":-0.422845}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:9770 accounts balance charlie --auth hi_charlie
{"asset_code":"XRP","balance":0.422845}

`
result-2 :

  -VirtualBox:~/interledger-rs$ ilp-cli accounts balance alice
{"asset_code":"ETH","balance":0.0}
-VirtualBox:~/interledger-rs$ ilp-cli accounts balance bob
{"asset_code":"ETH","balance":0.0}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:8770 accounts balance alice --auth hi_bob
{"asset_code":"ETH","balance":0.0}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:8770 accounts balance charlie --auth hi_bob
{"asset_code":"XRP","balance":-1.0}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:9770 accounts balance bob --auth hi_charlie
{"asset_code":"XRP","balance":0.0}
-VirtualBox:~/interledger-rs$ ilp-cli --node http://localhost:9770 accounts balance charlie --auth hi_charlie
 {"asset_code":"XRP","balance":0.0}

(And in different casse 's I get difference ilp _ adress value’s for charlie’s accounts)

A. In case when I create accounts in this steps: alice → alice -bob(Peer) → bob- alice (Peer) → bob- charlie (Child) → charlie -bob(Parent) → charlie

I get result’s like result-1

and this log’s :

I get this result’s like result-2

and this log’s :

P.S.:

Is any documentation for ilp-cli except help (-h flag) ?

And one more question: I get different values of ilp_adress for charlie in different cases. Why it happens?

Andrii_Spivak · March 26, 2020, 9:33am

One more thing that give some progress is changing some parameters for `

ilp-cli --node http://localhost:8770 accounts create charlie \

`from

–settle-threshold 0 \

to

--settle-threshold 500 \

(now I see transaction log in XRP testnet and ganache , but balance after on charlie-bob account is look like wrong)

Actually, look like, that now I need to go deeper in understanding this parameters using your post on github

In trying to setup an account that would prefund its peer, I couldn't find any d…ocumentation on what a positive/negative balance represents or how I should set the `settle_to`, nor what units I should use. The best I could find was this in line the ETH example: > The settle_threshold and settle_to parameters control when settlements are triggered. The node will send a settlement when an account's balance reaches the settle_threshold, and it will settle for balance - settle_to. We need to document, within the HTTP API specification _and_ the `ilp-cli` help text (and maybe elsewhere, too?): - When `settle_to` gets triggered, and what a positive or negative balance represents - What units the settlement parameters need to be in, with a couple examples (I was using an account with asset scale 2 and I tried to set `settle_to` to `4.52` but the CLI gave me a confusing error until I changed it to `452`. We should clarify this or change the API to use the standard, arbitrary precision representation of the asset, since it's more intuitive). Related to #120
