Building Out From Crypto Custody to Credit Servicing

Introduction

Institutions are under pressure to move beyond safekeeping and offer integrated credit services directly within their platforms. Clients want complex credit offerings, automated margining, and yield products built into the environments they already trust. But building prime services infrastructure in-house can take years, tie up engineering teams, and delay competitive entry. Membrane makes it possible in months.

The Challenge

Our client set out to deliver a full prime financing and yield solution embedded in its custody platform.To succeed, it needed to support bilateral loans, complex margin logic, and collateral monitoring in real time, and provide client-facing yield workflows, all while upholding security and operational integrity. Without this capability, the institution risked losing client assets to competitors offering integrated credit services sooner. Launching in-house would have required significant engineering resources and a potentially lost market opportunity.

Outcome

Prime Services Infrastructure
Membrane Collateral as a Service Flow Diagram
In as little as 3 months, the institution launched a fully embedded prime services and yield product. The platform captured new client assets and diversified revenue streams. It elevated the institution’s role from safekeeper to full-service financing provider, strengthening client trust while defending market share in a competitive landscape.

Future-Ready

The solution was built for growth: new loan structures, collateral types, and tokenized assets can be added without re-engineering. As institutional demand expands, our client can scale seamlessly.

Why It Matters

Custody alone is no longer enough. Institutions that fail to integrate credit services risk being disintermediated by competitors that do. By embedding prime services with Membrane, firms can strengthen client relationships, unlock new revenue opportunities, and position themselves as leaders in institutional credit infrastructure without the standard build times.
