The smart contracts for the Folks Finance Cross-Chain Lending Protocol.

The repository uses both Hardhat and Foundry.

To setup:

1. Clone the repo
2. Run npm install
3. Run forge install

To build:

1. (Optional) run npm run clean
2. Run npm run build

The smart contracts are split into 4 distinct folders:

• contracts/bridge contains all the smart contracts relating to sending messages (data and token) between the spoke chains and hub chain. Unless named specifically, they are deployed both in the spoke chains and hub chain.
• contracts/hub contains the smart contracts relating to the core business logic of the protocol. They are deployed only in the hub chain.
• contracts/oracle contains the smart contracts relating to the oracle for token price information. They are deployed only in the hub chain.
• contracts/spoke contains the smart contracts relating to the user entry point into the protocol. They are deployed only in the spoke chains (the hub chain may also be a spoke chain).

Within each you can also find test folder which contains smart contracts used for testing. These are not part of the protocol and won't be deployed.

To run all tests npm run test.

To run specific tests npm run test ${PATH_TO_FILE}.

If there is a license in a sub folder e.g. at /contracts/oracle then that applies for all files under it, otherwise refer to the license in the root folder.
