Toward Predictable Borrowing in DeFi with the Arkis Dynamic Spread Model

Traditional utilization models make borrowing unpredictable. Arkis fixes this with the Dynamic Spread Model — anchoring rates to collateral yields and target spreads for stable, predictable lending.

We’re reimagining prime brokerage—not as a centralized platform but as a highly customizable protocol.

Arkis is designed as a secure ecosystem for seamless, secure interactions to the decentralized economy—for asset managers, capital providers, and credit managers.


We offer Prime Brokerage-as-a-Service, meaning Arkis is built as a protocol, not a controlling body.


In traditional finance, prime brokerages function as centralized institutions with corporate governance, oversight, and decision-making power over their clients. DeFi, by stripping away these intermediaries, shifts the focus from centralized institutions to decentralized, trustless instruments that allow users to conduct financial operations without "entities" in the conventional sense. Arkis offers users a “walled garden” built entirely out of smart contracts that provides direct access to prime brokerage services—free from the entanglements of a centralized structure.

This isn’t just semantics; let’s explain how Arkis is decentralizing prime brokerage, from entity to protocol.
