"Niflheim"
Interledger Protocol support for ERC-20 on Layer 2 Network

Challenge Description
In ancient Norse Mythology, Niflheim 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?
What if Mike, upon receiving that WBTC, wanted to send WBTC to Brendan Eich, Creator of JavaScript and Co-founder of Brave, but Brendan only wanted to receive BAT?
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 ERC-20 on a Layer 2 network.

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 an ERC-20 token 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.
