minswap-py (v0.3.0)

minswap-py is a tool to interact with Minswap. The current version has feature parity with the minswap blockfrost-adapter, except for the ability to remove liquidity.

Documentation and additional features coming soon.

Changelog

Be sure to check out the CHANGELOG.md for a complete history of changes. This section only contains patch updates for the current minor version.

0.3.0

Improvements:

1. Added wallet support, including easy methods to create a collateral, send funds, and consolidate UTxOs.
2. Swap transactions.
3. Cancel transactions.
4. Deposit liquidity (including zap in), but should be updated in the future. The Minswap team has not responded to requests for details on how to better estimate expected LP based on amount of token deposited. https://github.com/minswap/sdk/pull/7#discussion_r1279439474

Changes:

1. There was an inconsistency in how time values were being cached. See the examples/rename_time.py for a way to translate previously cached data to the new standard.
2. Changed the way some of the underlying classes were managing amounts to use the Assets class. This makes combining assets from different UTxOs easier.

Installation

In order to use this package:

1. Install with pip install minswap-py
2. Sign up for blockfrost and get an API key.
3. In your working directory, create a .env file. The .env should have the following fields:

# The blockfrost project id
PROJECT_ID=

# The maximum number of calls allowed to Blockfrost within a session.
MAX_CALLS=45000

# Must be one of mainnet or preprod
NETWORK=mainnet

4. Browse the examples folder for use cases.

Setup your wallet

To use a wallet with minswap-py, you will need to supply a mnemonic in a file on your hard drive. By default, the Wallet class will create a brand new wallet and store it in .wallet/{chain}_mnemonic.txt. Then, this wallet will be used every time a new Wallet object is created. The chain in the file name must either be mainnet or preprod depending on what NETWORK you want to operate on (i.e. mainnet_mnemonic.txt or preprod_mnemonic.txt).

If you want to supply your own wallet, you can either replace the mnemonic in .wallets/{chain}_mnemonic.txt if it exists, or create it. You can also pass the mnemonic directly into the Wallet. Alternatively, you can create your own txt file with the mnemonic in it anywhere on disk, and pass that file to the Wallet constructor.

Examples:

from minswap.wallets import Wallet

# Initialize with a path to a file containing a mnemonic
wallet = Wallet(path="path/to/mnemonic.txt")

# Initialize with a mnemonic
wallet = Wallet(mnemonic="bert says buy flac")
