What the listing says

🆕 The per-transaction B20 rail check: pass token + from + to (+ optional executor) and get one GO/HOLD/STOP on whether this exact transfer clears NOW — sender policy resolved against the sender, receiver policy against the recipient, executor policy against the operator, plus live transfer-pause. Every other B20 tool is per-token due diligence bought once; this is the check an agent runs on every payment. No ERC-20 tool can see it.
