## Interledger Protocol support for ETH on Layer 2 Network
Gitcoin Sustain Web3 - https://hackathons.gitcoin.co/sustain-web3/
## Prize Bounty
$1000 in XRP
## Challenge Description
In ancient Norse Mythology, Vanaheim is one of the Nine Realms of Yggdrasil.
Xpring, much like the ancient Norse long before them, believes that in order for blockchain to reach mainstream adoption, there needs to be more interoperability between the siloed blockchain networks.
What if David Schwartz, the Chief Architect of the XRP Ledger, wanted to send XRP to Vitalik Buterin, the Creator of Ethereum, but Vitalik only wanted to receive ETH?
What if Vitalik, upon receiving that ETH, wanted to send ETH to Mike Belshe, Creator of HTTP/2 and CEO of BitGo, but Mike only wanted to receive WBTC?
and on and on...
How would these crypto pioneers achieve such a feat, without relying on exchanges?
Using Interledger Protocol (ILP), we challenge the Sustain Web3 virtual community to help complete ILP support for ETH on a Layer 2 network.
Xpring engineers will be available to answer questions and provide project guidance on the following public Gitcoin channel: xpring-vanaheim-challenge
## Test Networks

* Rust - https://github.com/interledger-rs/settlement-engines
## Core Libraries
* Xpring SDK - https://github.com/xpring-eng/Xpring-SDK
* Xpring SDK Java - https://github.com/xpring-eng/xpring4j
* Xpring SDK Swift - https://github.com/xpring-eng/xpringkit

### Submission Requirements
A valid submission will be code that is merged into the master branch of a repo that has demonstrated a successful transaction of ETH on a Layer 2 network using ILP.
We really love user interfaces, and the designers that build them, but UIs are not required (although appreciated!) for this Challenge. If time becomes a constraint, then we'd rather see more resources spent on getting the underlying settlement details correct.
### Submission Deadline
11:59am EST on Tuesday the 12th of February.
### Judging Criteria
Judges will evaluate based on the following criteria:
* project completeness
* complexity of implementation
### Winner Announcement Date
Judges from Xpring will be announcing the winners of the Vanaheim Challenge on Wednesday the 13th of February.
