CCIP Subgraphs

The following folder contains a subgraph for the CCIP router contract deployed on Arbitrum One on 01/25/2024.

This subgraph can be easily copied to index all CCIP router contracts on all chains. The full list of Router Addresses and Chain Selectors are below.

I was initially going to do all of them but decided that I would just submit this one since this is just an interview exercise.

CCIP works by having offRamp and onRamp contracts whereby each chain (for example, Arbitrum) has multiple offRamp contracts that can connect to it. onRamp contracts are the contracts that the router on Arbitrum uses to interact with the oracle network. Expressed visually:

Due to the architecture of CCIP, the data that is emitted by the Router contract is hashed with Keccak. This means that if the Receiver contract does not emit the raw data, the only way to see that data is to look at the CCIP (oracle) explorer.
