Create smart contract oracle for exchange rate lookup #121

Closed hansstammler closed 5 months ago

hansstammler commented 5 months ago

Create a smart contract oracle for cross-chain exchange rate lookup, should have some exploitable flaw

Alter currently existing router contracts to consult this oracle.

Hi @mojtaba-eshghie

I have added a bridge using an oracle contract. When pulling recent commits from main I can no longer run the test sequence where monitors are used, in the old or new implementation. I assume this is due to a file having moved, but I am unsure how to fix this, would appreciate advice.

Hi @hansstammler,

It should be because of lack of a results folder in the project root. This will be fixed in the next merge.
