Prime brokerage infrastructure for institutions, delivered on-chain



I spend a lot of time thinking about risk: how it is defined before capital moves, and how it is enforced once capital is already in the system. My second post on Arkis’ risk framework covers what happens after capital is deployed arkis.xyz/blog/how-arkis…

Most institutional strategies don't operate in a single venue. Collateral sits with custodians. Execution spans exchanges. Exposure can extend across both DeFi and CeFi simultaneously. Spark Prime extends overcollateralized lending across those environments under a unified risk framework. A deep dive from @hexonaut on the future of prime financing and how M1 Capital is using the infrastructure today.

Relook: Spark Prime is CeDeFi margin lending for institutional borrowers. Most institutional strategies do not operate in one venue. Collateral sits with custodians, execution moves across exchanges, and exposure runs through DeFi protocols and traditional market infrastructure. Spark Prime extends overcollateralized lending across these environments. Powered by @ArkisXYZ margin technology, it operates within a defined risk framework, with positions visible in real time. The result is institutional financing infrastructure built around the full position, not one venue.

Crypto credit still treats risk as something reconstructed after the fact - collateral sits on one venue, positions on another and exposure only becomes visible once markets move. We think this is the wrong architecture for institutional markets.




The kelpDAO incident reignited the "AAVE's multi-collateral model is fragile, go siloed" take. For me, this approach misses the point. Lenders want to pick their risk exposure → segregated markets. Borrowers want capital efficiency → portfolio margin. In my opinion, both are right. Siloed markets mean collateral drag, fragmented liquidity, and position-level liquidation risk instead of portfolio-level. That's exactly why institutions flooded into AAVE in the first place — portfolio margining is the default at every prime broker and every clearinghouse. Retreating to one collateral per market is a step backward for an industry whose entire pitch is capital efficiency. But the lender side isn't wrong either. Outsourcing your risk preference across N collateral types to a single curator ≠ expressing your own risk view. The real question isn't siloed vs. unified. It's: how do you let lenders define which collateral they back and at what size, while borrowers still cross-margin their full portfolio against the aggregate pool? That's the design problem worth solving. Not retreating to silos.




Collateral eligibility is determined by infrastructure, not just asset quality. In this clip, CEO @serjxyz explains why even institutional-grade, VC-backed assets get rejected. Without a pricing oracle and a credible liquidation path, hardcoded 1:1 valuations don't hold up.


1. Every prime broker eventually runs into the same quiet problem: security and user experience are a seesaw. Push one side down and the other comes up. There is no configuration where both are maximized at once - only a point where the trade-off stops hurting too much.

The Arkis platform unifies DeFi and CeFi under a single margin framework. Post collateral once. Use it across every connected venue — no siloed accounts, no fragmented positions. @proskurinalex on how prime brokerage-as-a-service works:
