Self-custody began with a centralized path to an Ethereum proof
edgeX V1 combined a central limit order book with StarkEx. Users signed with Ethereum and STARK keys; an operator ordered trades, StarkEx batched state transitions, SHARP produced proofs, and Ethereum contracts accepted proved roots. Funds sat in contracts rather than an exchange omnibus wallet, with forced withdrawals as an operator-failure route.
That structure reduced custody risk without removing the operator. Matching availability, order sequencing, oracle marks, liquidations and the interface still shaped a trader’s outcome. The terms even say edgeX Trading Inc. supplies software rather than execution, clearing or settlement, while retaining the ability to restrict the interface.
