mytonlib 0.7.4

Native library for working with TON (The Open Network)

What is it?

This is a native library for working with The Open Network - without using libtonlibjson.so. But for nativeness, we have to pay with speed. This library was written based on this documentation: https://github.com/xssnick/ton-deep-doc

Installation

pip3 install mytonlib

How to use

from mytonlib import AdnlTcpClientWithBalancer

global_config_url = "https://ton-blockchain.github.io/global.config.json"
adnl = AdnlTcpClientWithBalancer(global_config_url)

# Get masterchain info
adnl.get_masterchain_info()

How to use without balancer

from mytonlib import AdnlTcpClient

# Take public lite-server from https://ton-blockchain.github.io/global.config.json
host = "185.86.79.9"
port = 4701
pubkey = "G6cNAr6wXBBByWDzddEWP5xMFsAcp6y13fXA8Q7EJlM="

# Connect to the lite-server with adnl
adnl = AdnlTcpClient()
adnl.connect(host, port, pubkey)

# Test connection
adnl.ping()

# Get masterchain info
adnl.get_masterchain_info()

List of available functions

All available functions are taken from lite-client

connect 				# Connect to the lite-server with adnl
ping 					# Test connection
get_time 				# Get server time
get_masterchain_info 	# Get last block and state info from server
get_account_state		# Loads the most recent state of specified account
run_smc_method			# Runs GET method <method-id> of account <addr> with specified parameters
get_all_shards_info		# Shows shard configuration from the most recent masterchain state or from masterchain state corresponding to <block-id-ext>
get_config_params		# Shows specified or all configuration parameters from the latest masterchain state
get_block_header		# Shows block header for <block-id-ext>
get_block				# Downloads block
get_last_transactions	# Shows or dumps specified transaction and several preceding ones
get_block_transactions	# Lists block transactions, starting immediately after or before the specified one
get_one_transaction		# Dumps one transaction of specified account
lookup_block			# Looks up a block by workchain, shard and seqno/lt/time, and shows its header

TLB unpacking

A feature of this library is the automatic unpacking of data according to the TLB scheme:

from mytonlib import TlbSchemes

tlb_schemes = TlbSchemes()
tlb_schemes.load_schemes("/usr/src/ton/tl/generate/scheme/")

data = adnl.run_smc_method("kQBL2_3lMiyywU17g-or8N7v9hDmPCpttzBPE2isF2GTziky", "mult", [5, 4])
print(data) # or print(json.dumps(data, indent=4))

tlb_schemes.load_schemes_from_text("mycell$_ value:uint64 = MyCell;")
data = tlb_schemes.deserialize(data, expected="MyCell")
print(data.value)
