Custody and Counterparty
Custody and counterparty analysis should separate the protocol model from the current closed beta operating model.
Protocol Layer
At the protocol level, margin and positions are housed in dedicated account contracts. That reduces reliance on a traditional offchain venue ledger for core trading state.
Beta Service Layer
The current Broadcast service signs transactions for registered users in the closed beta. That means the present stack introduces an operational custody layer around the protocol for some users.
Counterparty Model
Ollo's design is closer to a collateral-first venue model than a bilateral prime-brokerage model. Counterparty exposure is shaped by posted margin, execution rules, and settlement logic rather than by dealer relationship alone.
Conservative Reading
The current relay model is part of the present operating posture, not a universal requirement for every future deployment.
