AI agent execution skill for crypto order execution — TWAP, maker execution, transaction cost analysis and slippage reduction. Supports 11 CEX and DEX venues on both perpetual futures and spot: Binance, OKX, Bybit, Bitget, Gate.io, KuCoin, Kraken, Deribit, Hyperliquid, Aster and Orderly. Exchange API keys stay on the user's own machine — no third-party order routing. Install and full docs: https://pypi.org/project/blockfill/.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## What is BlockFill Agent Execution BlockFill Agent Execution is an **AI agent execution skill for crypto order execution**.

How to install
mdr add starchild-ai-agent/official-skills/blockfill-agent-execution@sha256:55dcc010f6340321The line at the top of this page pins the label v2.1.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
