Selecting an Architecture

The determining question is what the participant is acquiring.

Product characteristic	Architecture
A managed return that must be produced, such as market-neutral trading, credit underwriting, lending, or structured yield	Curator-Vault
A defined basket of assets to be held and kept balanced	OTP
Exposure requiring pooling to function, such as capacity-limited strategies or shared counterparty positions	Curator-Vault
Exposure where direct ownership, per-asset control, and structural transparency are required	OTP
A product requiring a transferable claim token for use elsewhere onchain	Curator-Vault
A container that must hold vault positions alongside other assets	OTP

Both architectures are non-custodial, both enforce a published rule set, and both publish methodology and operating history. They differ in whether capital is pooled to produce a return or held as the exposure itself.
