Json-RPC API Methods Documentation

Pharos is a high-performance, EVM-compatible Layer 1 blockchain designed to offer a seamless development experience for Ethereum developers. Anyone familiar with Ethereum's ecosystem will find building on Pharos intuitive and efficient.

Pharos provides a JSON-RPC interface for blockchain interactions. Developers can refer to the RPC-API documentation for a comprehensive list of supported methods.

Currently, Pharos is under active development and running in a private DevNet. Public RPC endpoints and access details will be announced in the near future.

This section serves as an interactive reference for Pharos' JSON-RPC API, helping developers integrate and interact with the network effectively.

EVM Example

Example ERC-20 Token Details

To ensure a consistent reference, below is a predefined ERC-20 token example instead of selecting a random one from the chain explorer.

Token Name: Pharos Test Token (PTT)
Smart Contract Address: 0xcB8a4dF93DEB878ae10044E37Ffc1ea7450630b8

Example RPC Calls

Below are sample RPC requests using the Pharos Devnet endpoint.

1. Get the Latest Block Number

Request:

{
    "jsonrpc": "2.0",
    "method": "eth_blockNumber",
    "params": [],
    "id": 1
}

Curl Example:

curl <https://devnet.dplabs-internal.com/> \\
  -X POST \\
  -H "Content-Type: application/json" \\
  --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'

Response:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": "0x1fdde"
}

2. Get Token Balance of an Address

  --data '{"method":"eth_call","params":[{"from": null,"to":"0x9C05F9bED4d87541722048558556BBAE197ea481","data":"0x70a082310000000000000000000000006E0d01A76C3Cf4288372a29124A26D4353EE51BE"}, "latest", {"0x1111111111111111111111111111111111111111": {"balance": "0xFFFFFFFFFFFFFFFFFFFF"}}],"id":1,"jsonrpc":"2.0"}'

Response:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": "0x0000000000000000000000000000000000000000000000000000000000000000"
}

3. Get Token Transfer Events

Request:

Additional Information

The above examples showcase how to interact with the Pharos Devnet RPC for querying ERC-20 tokens.
Replace contract addresses and data fields with your specific token details where necessary.
For more RPC methods, refer to Ethereum-compatible RPC documentation.

If you have any further questions or need additional examples, please reach out to the Pharos development team.
