## How can I access the Charged Particles Protocol?

The Charged Particles protocol exists as open-access [Smart Contracts ](https://en.wikipedia.org/wiki/Smart_contract)on the Ethereum Blockchain. This means that interacting with the protocol is permissionless - anyone can build a DApp layer or communicate directly with the blockchain to access the Charged Particles protocol. 

Our [Contracts](#contract-addresses) and [Subgraphs](https://docs.charged.fi/charged-particles-protocol/developing-on-the-protocol/protocol-subgraph) are both open-source and available on Github.
