Tinyman Python SDK

Design Goal

This SDK is designed for automated interaction with the Tinyman AMM. It will be most useful for developers who wish to create automated trading programs/bots. It may also be useful to create an alternative UI but that is not a design goal of this library. It is designed to be reasonably low level so that pieces can be used in isolation.


This SDK is currently under active early development and should not be considered stable.


tinyman-py-sdk is not yet released on PYPI. It can be installed directly from this repository with pip:

pip install git+https://github.com/tinymanorg/tinyman-py-sdk.git

Sneak Preview

from tinyman.v1.client import TinymanTestnetClient

client = TinymanTestnetClient()

# Fetch our two assets of interest
TINYUSDC = client.fetch_asset(21582668)
ALGO = client.fetch_asset(0)

# Fetch the pool we will work with
pool = client.fetch_pool(TINYUSDC, ALGO)

# Get a quote for a swap of 1 ALGO to TINYUSDC with 1% slippage tolerance
quote = pool.fetch_fixed_input_swap_quote(ALGO(1_000_000), slippage=0.01)
print(f'TINYUSDC per ALGO: {quote.price}')
print(f'TINYUSDC per ALGO (worst case): {quote.price_with_slippage}')

# See the examples for the rest...


Basic Swapping

swapping1.py This example demonstrates basic functionality including:

  • retrieving Pool details
  • getting a swap quote
  • preparing swap transactions
  • signing transactions
  • submitting transactions
  • checking excess amounts
  • preparing redeem transactions

swapping1_less_convenience.py This example has exactly the same functionality as swapping1.py but is purposely more verbose, using less convenience functions.

Basic Pooling

pooling1.py This example demonstrates retrieving the current pool position/share for an address.

Basic Add Liquidity (Minting)

add_liquidity1.py This example demonstrates add liquidity to an existing pool.

Basic Burning



  • Methods starting with fetch_ all make network requests to fetch current balances/state.
  • Methods of the form prepare_X_transactions all return TransactionGroup objects (see below).
  • All asset amounts are returned as AssetAmount objects which contain an Asset and amount (int).
  • All asset amount inputs are expected as micro units e.g. 1 Algo = 1_000_000 micro units.

Signing & Submission

The SDk separates transaction preparation from signing and submission to leave the developer in full control of how transactions are signed and submitted to the network.


The prepare_X_transactions methods all return a TransactionGroup object. This is a container object containing a list of transaction objects (.transactions) and a list for signed transactions (.signed_transactions).

transaction_group = client.prepare_app_optin_transactions(account['address'])


In most cases some of the transactions have a corresponding entry in .signed_transactions because they have been signed by the Pool LogicSig. The remaining transactions should be signed by the ‘user’.

The TransactionGroup includes a method to do this when signing with a private key:

transaction_group.sign_with_private_key(account['address'], account['private_key'])

This helper method is equivalent to the following:

for i, txn in enumerate(transaction_group.transactions):
    if txn.sender == account['address']:
        transaction_group.signed_transactions[i] = txn.sign(account['private_key'])

Any alternative method of signing can be used here following the same pattern. For example using KMD:

kmd = algosdk.kmd.KMDClient(KMD_TOKEN, KMD_ADDRESS)
handle = kmd.init_wallet_handle(KMD_WALLET_ID, KMD_WALLET_PASSWORD)
for i, txn in enumerate(transaction_group.transactions):
    if txn.sender == account['address']:
        transaction_group.signed_transactions[i] = kmd.sign_transaction(handle, KMD_WALLET_PASSWORD, txn)

A User account LogicSig can also be used in a similar way or using the sign_with_logicisg convenience method:



A TransactionGroup containing fully signed transactions can be submitted to the network in either of two ways:

Using an Algod client:

algod = AlgodClient(TOKEN, ADDRESS, headers={'User-Agent': 'algosdk'})
txid = algod.send_transactions(transaction_group.signed_transactions)

Or, using the convenience method of the TinymanClient:

result = client.submit(transaction_group, wait=True)

This method submits the signed transactions and optionally waits for confirmation.
