Band protocol IBC Challenge

vuong177 commented 2 years ago

What me and Vinh did:

Create a local bainchain, include data source, data script, v.v. Just change length used in validation of port identifiers to 128 to create ibc channel from juno contract to bandchain. My bandchain code here
Create a Ibc channel from juno mainet to my local bandchain (I can't use band mainet because they don't approve wasm port, they still use ibc v1.1.5, length used in validation of port identifiers still 64)
I tried use laozi-testnet, but it have this error, it's reason i used local testnet
Create a smart-contract for request oracle data over IBC. Smart contract code here. I've store it in Juno mainnet (code_id = 52)
Call contract to query oracle data over IBC and received oracle data.

@JakeHartnell pls have a look, sir

Repo doesn't seem to be public: https://github.com/notional-labs/oracle-ibc/tree/main/contracts

Could you submit a PR to band protocol to start discussion? They need to upgrade their IBC version, would love to use their oracles in contracts. CC @faddat.

@JakeHartnell, can you take a look at our solution

blockcreators commented 2 years ago

The band channel is created right @faddat

Do you mind sharing the ID for it again? Thanks!

the-frey commented 2 years ago

I think we're waiting on band to commit to an IBC version bump?

vuong177 commented 2 years ago

@the-frey yes. Band mainnet is using ibc v1.1.5. It don't allow wasm port.

JakeHartnell commented 2 years ago

We need to pressure them to upgrade or we should launch a better oracle solution.

vuong177 commented 1 year ago

Is this bounty still available? Bandprotocol has upgraded their testnet to ibc v3 and we can enable ibc with wasm port on it.
