megatao-sdk 0.1.0

Python SDK for MegaTAO on Bittensor

MegaTAO Python SDK

Python client for the MegaTAO perpetual futures API on Bittensor.

Installation

pip install megatao-sdk

To enable on-chain write operations (deposit, withdraw, open/close positions), install the chain extra:

pip install megatao-sdk[chain]

---

Overview

The SDK exposes two sub-clients on the MegaTAO object:

Sub-client	Access	Purpose
Info	client.info	Read-only REST API — markets, prices, positions, orders, account data
Chain	client.chain	On-chain writes — deposit, withdraw, open/close positions, place/cancel orders

client.chain is only available when private_key and rpc_url are provided at construction.

---

Info Client

Read market data and account state via the REST API. No private key required.

from megatao_sdk import MegaTAO

with MegaTAO() as client:
    markets = client.info.markets()
    for m in markets:
        print(f"{m.symbol}: {m.price}")

Methods

Method	Description
markets()	List all available markets
market(address)	Detailed info for a single market
prices()	Current prices for all markets
orderbook(market, levels=10)	Order book depth for a market
positions(address)	Open positions for a trader
orders(address)	Open limit orders for a trader
margin(address)	Account summary and margin balances
trades(address)	Trade history for a trader
vault()	Vault state (reserves, insurance fund)
funding()	Current funding rates
platform_stats()	Aggregate platform statistics
leaderboard(limit=50, sort_by="pnl")	Trader leaderboard
candles(market, resolution="1h", from_ts=None, to_ts=None)	OHLCV candle data

All responses are typed Pydantic models. Numeric values are strings to preserve precision.

market = client.info.markets()[0]
market.symbol       # "BTC-USD"
market.price        # "67000.00"
market.max_leverage # 50

Async

import asyncio
from megatao_sdk import AsyncMegaTAO

async def main():
    async with AsyncMegaTAO() as client:
        markets = await client.info.markets()
        positions = await client.info.positions("0xYourAddress")

asyncio.run(main())

---

Chain Client

Submit on-chain transactions. Requires pip install megatao-sdk[chain] and a funded wallet.

from megatao_sdk import MegaTAO
from megatao_sdk.chain import TAO

client = MegaTAO(
    private_key="0xYourPrivateKey",
    rpc_url="https://your-bittensor-rpc-url",
)

# Deposit collateral
tx_hash = client.chain.deposit(1 * TAO)

# Open a 10x long
tx_hash = client.chain.open_market_position(
    market="0xMarketAddress",
    is_long=True,
    margin_wei=1 * TAO,
    leverage_wei=10 * TAO,
    max_slippage_bps=50,
)

# Close a position (size_to_close_wei=0 closes fully)
tx_hash = client.chain.close_position(position_id=b"...", size_to_close_wei=0)

# Withdraw collateral
tx_hash = client.chain.withdraw(1 * TAO)

TAO = 10**18 — all amounts are in wei (18 decimals).

Pass wait_for_receipt=True to any method to block until mined and return a TxReceipt instead of a tx hash.

Methods

Method	Description
deposit(amount_wei)	Deposit TAO as collateral
withdraw(amount_wei)	Withdraw collateral
open_market_position(market, is_long, margin_wei, leverage_wei, max_slippage_bps)	Open a market order position
close_position(position_id, size_to_close_wei=0)	Close a position (0 = full close)
place_limit_order(market, is_buy, margin_wei, leverage_wei, price_wei, reduce_only_type=0)	Place a limit order
place_take_profit(market, is_buy, margin_wei, leverage_wei, price_wei)	Place a take-profit order (reduce-only, triggers on favorable price)
place_stop_loss(market, is_buy, margin_wei, leverage_wei, price_wei)	Place a stop-loss order (reduce-only, triggers on adverse price)
cancel_order(market, order_id)	Cancel a specific limit order
cancel_all_orders(market)	Cancel all open orders for a market

Async

from megatao_sdk import AsyncMegaTAO
from megatao_sdk.chain import TAO

client = AsyncMegaTAO(
    private_key="0xYourPrivateKey",
    rpc_url="https://your-bittensor-rpc-url",
)

tx_hash = await client.chain.deposit(1 * TAO)

---

Error Handling

from megatao_sdk import MegaTAO, APIError, MegaTAOError

with MegaTAO() as client:
    try:
        info = client.info.market("0xInvalidAddress")
    except APIError as e:
        print(f"HTTP {e.status_code}: {e.message}")
    except MegaTAOError as e:
        print(f"SDK error: {e}")
