QSG Integrates with Kraken to Bring Institutional-Grade Execution to Kraken Users

_{October 21, 2026}

Quantech Services Group (QSG) integrates with Kraken. Kraken users can now directly access Selsus BlockFill Agent Execution, QSG’s execution engine for large orders.

As digital asset markets mature, trading performance depends more and more on execution quality. Strategy and market conditions still matter, but so does how efficiently large orders reach the market. As AI agents take on a growing share of trading, they also need execution infrastructure built for them.

Selsus BlockFill Agent Execution: Institutional-Grade Execution for Kraken Users

Large orders come with hidden costs from slippage and market impact. Selsus BlockFill Agent Execution is a Python SDK and local execution engine that helps traders and AI agents execute large orders efficiently on Kraken’s spot and perpetual futures markets.

• Designed to reduce slippage versus standard TWAP: the cost advantage on large orders has been verified in live trading.
• Built for AI agents: works as an execution skill for AI agents, MCP servers and trading copilots.
• Runs locally: your Kraken API keys never leave your machine.
• Execution only: Selsus BlockFill optimizes how your orders are executed. It does not generate trading signals or make trading decisions for you.

Developers can install Selsus BlockFill from PyPI:

python3 -m pip install -U blockfill
