# MosPy

MosPy is a fork of the cosmospy library and aims to be a versatile transaction signing library for the whole cosmos ecosystem.

It depends [cosmospy-protobuf](https://github.com/ctrl-Felix/cosmospy-protobuf) for the protos. Through this library you also can add your own transaction types and sign them through Mospy.

## Documentation

A documentation with according examples can be found at https://mospy.ctrl-felix.de

## Get Started

You can find a tutorial series on medium: https://medium.com/@ctrl-felix/mospy-tutorial-1-the-basics-95ec757047dc

## Installation

Mospy is available through (pypi)[https://pypi.org/project/mospy-wallet]

`python -m pip install mospy-wallet`

_Note: The package name in python is mospy even if it is called mospy-wallet on pypi as mospy already existed_

## Quickstart

More examples on: https://mospy.ctrl-felix.de/examples/

```python

import httpx # optional

from mospy import Account, Transaction

account = Account(

    seed_phrase="law grab theory better athlete submit awkward hawk state wedding wave monkey audit blame fury wood tag rent furnace exotic jeans drift destroy style",

    address_index=12

)

tx = Transaction(

    account=account,

    gas=1000,

)

tx.set_fee(

    amount=100,

    denom="uatom"

)

# Add a transfer message to the transaction (multiple messages can be added)

tx.add_msg(

    tx_type='transfer',

    sender=account,

    receipient="cosmos1tkv9rquxr88r7snrg42kxdj9gsnfxxg028kuh9",

    amount=1000,

    denom="uatom"

)

# Sign and encode transaction to submit it to the network manually

# REST endpoint (RPC or API)

tx_bytes = tx.get_tx_bytes_as_string()

# Submit the transaction through the Tendermint RPC

rpc_url = "https://rpc.cosmos.network/"

pushable_tx = json.dumps(

              {

                "jsonrpc": "2.0",

                "id": 1,

                "method": "broadcast_tx_sync", # Available methods: broadcast_tx_sync, broadcast_tx_async, broadcast_tx_commit

                "params": {

                    "tx": tx_bytes

                }

              }

            )

r = httpx.post(rpc_url, data=pushable_tx)

# Submit the transaction through the Cosmos REST API

rpc_api = "https://api.cosmos.network/cosmos/tx/v1beta1/txs"

pushable_tx = json.dumps(

                {

                  "tx_bytes": tx_bytes,

                  "mode": "BROADCAST_MODE_SYNC" # Available modes: BROADCAST_MODE_SYNC, BROADCAST_MODE_ASYNC, BROADCAST_MODE_BLOCK

                }

              )

r = httpx.post(rpc_api, data=pushable_tx)

```

## Different transaction types

Mospy is created to support every possible external transaction type.

To make it easier some transaction types are built in and can be added directly to a transaction object.

But it's not difficult to add your own transaction types! More about transaction types can be found in the docs.
