8. Risk Controls and Operational Constraints

BASIS applies deterministic execution controls and state-machine-based safeguards designed for execution precision and structural alpha capture.

Parameter	Threshold	Description
Max Single-Trade Size	2% of managed capital	No single strategy action may exceed this capital allocation limit.
Max Venue Exposure	25% of managed capital	Exposure concentration per venue is capped.
Capital Deployment Ratio	70%–85%	A reserve buffer is maintained for liquidity, operations, and risk events.
BSCB Activation	Trigger-based	BASIS Smart Circuit Breaker may pause selected strategy modules under predefined conditions.
DMM Activation	Extreme conditions	Defensive Maintenance Mode may halt strategy activity when multiple risk triggers align.

Infrastructure profile:

• BHLE routing stack

• Sub-50μs latency

• 100K+ OPS

• Proprietary routing infrastructure

• Math-constrained execution logic

• Deterministic state transitions for risk containment

Research support is provided through Base58 Labs, serving as a Research Partner for strategy and systems research.

9. Risk State Behavior

State	Behavior
BSCB	Selected strategy modules may pause. New positions may be restricted. Existing exposure is managed under tighter controls. Deposits and withdrawals generally remain available.
DMM	Strategy execution may halt in favor of capital preservation. Withdrawal processing may become more conservative if orderly unwinding is required.
