Python client for Ethereum JSON RPC Server

> Note that this currently only implements a handful of the JSON RPC methods > exposed by the server.

## Installation

Install with pip

`bash $ pip install ethereum-rpc-client `

## Basic Usage

Assuming you have an Ethereum node running the JSON RPC server on localhost:8454

`python >>> from eth_rpc_client import Client >>> client = Client(host="127.0.0.1", port="8454") >>> client.get_coinbase() ... '0xd3cda913deb6f67967b99d67acdfa1712c293601' `

## API

### Client.get_coinbase()

> https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_coinbase

Returns the hex encoded coinbase.

### Client.get_gas_price()

> https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_gasprice

Returns the gas price in wei as an integer

### Client.get_balance(address, block=”latest”)

> https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_getbalance

• address: The hex encoded address to lookup the balance for.

• block: The block to use for the lookup.

Returns the account balance for the address in wei as an integer.

### Client.get_code(address, block=”latest”)

> https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_getcode

• address: The hex encoded address to lookup the code for.

• block: The block to use for the lookup.

Returns the code at the given address.

### Client.call(_from=None, to=None, gas=None, gas_price=None, value=0, data=None, block=”latest”)

> https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_call

• _from: The hex encoded address to use as the source for the call.

• to: The hex encoded address of the contract for the call.

• gas: Integer gas alotment for the call.

• gas_price: Integer gas price in wei.

• value: Integer amount in wei to send with the call.

• data: The call data.

Returns the call response.

### Client.get_transaction_receipt(txn_hash)

> https://github.com/ethereum/wiki/wiki/JSON-RPC#eth_gettransactionreceipt

• txn_hash: The hex encoded transaction hash to lookup.

Returns a dictionary of the transaction receipt or None if no receipt is found.

• transactionHash: hex encoded hash of the transaction.

• transactionIndex: integer of the transactions index position in the block.

• blockHash: hex encoded hash of the block where this transaction was in.

• blockNumber: integer block number where this transaction was in.

• cumulativeGasUsed: The total amount of gas used when this transaction was executed in the block.

• gasUsed: The amount of gas used by this specific transaction alone.

• contractAddress: The contract address created, if the transaction was a contract creation, otherwise null.

• logs: list of log objects, which this transaction generated
