IBC Contracts

Ethan's HackAtom video. Intro starts here about basic interfaces: https://www.youtube.com/watch?v=x75UobIr4qo&t=7077s

• IBC interface definition
• simple example contract

Here I get into a real example, implementing "Simple ICA" contracts that are similar to Interchain Accounts: https://www.youtube.com/watch?v=x75UobIr4qo&t=9070s

• Simple ICA example: Example IBC enabled contracts along with full stack integration tests (v0.1.1 is the functionality demo'd in the video - later versions are improvements on the protocol

Here is the code and tests for another approach, a contract speaking standard ics20 protocol, so it connects to standard Go module on a non-CosmWasm chain:

• ics20-cw20 example
• integration tests for ics20-cw20
