## Chainlink CCIP - Proof of Concept
### Description:
This project demonstrates cross-chain message passing using Chainlink CCIP between the Base Chain (Sepolia testnet) and Optimism (Sepolia testnet). It allows sending a wallet address from Optimism to Base and retrieving the associated tier information.
### Prerequisites:
- Node.js (https://nodejs.org/)
- Foundry (https://github.com/foundry-rs/foundry)
### Clone the repository:
```shell
$ git clone [email protected]:skeletordapps/chainlink-ccip-poc.git
```
### Install Foundry dependencies:
```shell
$ foundryup && forge install
```
### Configuration:
Create a ```.env``` file in the project root directory with the following environment variables:
```shell
BASE_SEPOLIA_RPC_URL="https://sepolia.base.org"
OPTIMISM_SEPOLIA_RPC_URL="https://sepolia.optimism.io"
BASE_SEPOLIA_CHAIN_SELECTOR=10344971235874465080
OPTIMISM_SEPOLIA_CHAIN_SELECTOR=5224473277236331295
BASE_SEPOLIA_ROUTER_ADDRESS=0xD3b06cEbF099CE7DA4AcCf578aaebFDBd6e88a93
OPTIMISM_SEPOLIA_ROUTER_ADDRESS=0x114A20A10b43D4115e5aeef7345a1A71d2a60C57
BASE_SEPOLIA_LINK_ADDRESS=0xE4aB69C077896252FAFBD49EFD26B5D171A32410
OPTIMISM_SEPOLIA_LINK_ADDRESS=0xE4aB69C077896252FAFBD49EFD26B5D171A32410
WALLET_A=0x
WALLET_B=0x
WALLET_C=0x
```
**Important:** Replace the placeholder wallet addresses ```(WALLET_A, WALLET_B, WALLET_C)``` with your actual testnet wallet addresses if you intend to use them in the tests.
### Test
```shell
$ forge test && forge coverage
```
### Coverage
Ran 1 test suite in 21.46s (21.46s CPU time): 3 tests passed, 0 failed, 0 skipped (3 total tests)

| Total | 88.68% (47/53) | 85.92% (61/71) | 60.00% (3/5) | 87.50% (14/16) |
### Contracts
```Tier.sol```
Defines tiers on the Base Chain, each with a name, minimum points, and maximum points.
```Points.sol```
Manages a list of wallets and their corresponding points on the Base Chain. This contract is used to determine the tier associated with a wallet's points.
```Ask.sol```
Deployed on Optimism, this contract facilitates sending a wallet address to the Base Chain to retrieve tier information.
```Answer.sol```
Receives requests from other chains (in this case, Optimism) to check the tier of a specified wallet address on the Base Chain.
### Additional Notes:
- Remember to replace the placeholder wallet addresses in the ```.env``` file with your own ```testnet addresses``` if you plan to use them in the tests.
- Ensure that you have sufficient testnet ```funds``` in your wallets to cover gas costs during testing.
- This poc only aims to test crosschain messages sending a question and obtaining an answer, that's why we don't have a full coverage for all aspects.
