In3 client for python

Project description

IN3 Python Client

This is a simple test using in3 python library

Creating a new instance

in3 = In3Client()

Creating a new instance from default configurations

In3Client.create_in3_client_from_default_config()

Creating a new instance from my custom configuration

config = IN3Config()
config.chainId = EnumsChains.MAINNET.value.chain_id
in3 = In3Client(config=config)

Calling ETH function from our In3 Client

in3  = In3Client.create_in3_client_from_default_config()
in3.eth.block_number()

In3Types

We have some classes that can help you write some simple and safe codes using our client.

Bytes20

This class help you write 20 bytes parameters and validate it

from src.domain.bytes_types import Bytes20
address = Bytes20('0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b')

Bytes32

This class help you write 32 bytes paramters like hashes.

from src.domain.bytes_types import Bytes32
block_hash = Bytes32('0xc94770007dda54cF92009BFF0dE90c06F603a09f')

In3Number

This class can help you write numbers (hex and int) to handle block numbers

from src.domain.in3_number import In3Number
number = In3Number(0x76c0)
number.to_hex() #0x76c0
number.to_int() #30400

EnumBlockStatus

This Enum stands for block number parameters string "latest", "earliest" or "pending"

from src.enums.enums_block_status import EnumsBlockStatus
default_block_number = EnumsBlockStatus.LATEST

Functions

We can call different kinds of functions using the In3 Client.

*IPFS will be supported soon

Ethereum

You can call ethereum functions using our client

  • Assuming that you have the In3 Client setted correctly as we did before, we can call these functions.
in3 = In3Client.create_in3_client_from_default_config()
in3.eth

The eth module is responsible to call all ethereum functions using our client to make the things easier.

eth_getUncleCountByBlockNumber

Returns the number of uncles in a block from a block matching the given block number.

eth.get_uncle_count_by_block_number(EnumsBlockStatus.LATEST)

eth_sign

The sign method calculates an Ethereum specific signature with: sign(keccak256("\x19Ethereum Signed Message:\n" + len(message) + message))).

By adding a prefix to the message makes the calculated signature recognisable as an Ethereum specific signature. This prevents misuse where a malicious DApp can sign arbitrary data (e.g. transaction) and use the signature to impersonate the victim.

Note the address to sign with must be unlocked.

address = Bytes20('0x9b2055d370f73ec7d8a03e965129118dc8f5bf83')
message = '0xdeadbeaf'
eth.sign(address,message)

get_storage_at

Returns the value from a storage position at a given address.

position = In3Number(0x0)
storage = eth.get_storage_at(address, position, EnumsBlockStatus.LATEST)

get_code

address = Bytes20('0xa94f5374fce5edbc8e2a8697c15331677e6ebf0b')
number = In3Number(0x0)
code = eth.get_code(address, number)
