# Chain RPC

<figure><img src="/files/RcBp31dPWgZ1xmizOkks" alt=""><figcaption></figcaption></figure>

To interact with dKargo Chain or develop applications on it, access to a dKargo Chain Node is required.

The dKargo Chain RPC (Remote Procedure Call) provides a JSON-RPC interface, enabling developers and applications to programmatically interact with dKargo Chain Nodes.

Through this interface, various operations can be performed, including:

* Querying blockchain data (e.g., balances, blocks, transactions)
* Submitting write operations (e.g., deploying contracts, sending transactions)

As an EVM-compatible RPC, dKargo Chain supports Ethereum-like methods, allowing seamless integration with tools such as ethers.js and Web3.js.
