Composite Strategies

Risk partners let the RiskEngine recognize supported combinations within a TokenId. Each leg identifies its partner through riskPartner; self-partnered legs are evaluated independently. TokenId validation and the engine's classification rules determine whether two legs receive composite treatment.

Classification matters

The engine distinguishes option spreads, short strangles, loan/option combinations, and credit/option combinations using leg attributes. Width, direction, token type, ratios, and asset frame matter. A name such as spread or covered call in a UI is not sufficient to select a formula.

The RiskEngine reference documents _getRequiredCollateralSingleLegPartner and its strategy-specific calculations. The stock engine reference and deployed parameters identify the applicable policy.

Evaluate the complete portfolio

Calculate requirements in token units before valuation. Mixed-asset frames can require conversion even when two legs appear to share a strike or notional. Evaluate both token0/token1 orderings, both surplus directions, and the account's other positions and streamia (streaming premium) balances.

Risk partnering does not remove account-level solvency checks, interest, mint buffers, or safe-mode restrictions. Supply the full position list to simulation and compare the resulting account state, not just the sum of individual leg estimates.
