Why Crypto-as-a-Service Alone Is Not Enough for Banks and Brokers

Crypto-as-a-Service (CaaS) has become the fastest way for banks and brokers to launch digital asset trading without building infrastructure from scratch. A CaaS provider gives an institution outsourced access to execution, custody, and counterparty connectivity. These elements would otherwise take years and significant capital to build in-house, so for an institution under pressure to launch quickly, Crypto-as-a-Service offers a compelling proposition. 

But speed to market and completeness are not the same thing. Crypto-as-a-Service solves the street-side of a digital asset operation, handling the relationship between the institution and its trading and custody counterparties. It does not remove the institution’s responsibilities for managing client accounts, pricing and quoting, fee construction, reconciliation, allocation, portfolio management, bookkeeping, and integration with internal systems. Regardless of how sophisticated the provider may be, these responsibilities stay with the bank or broker. 

This insight will explain exactly what Crypto-as-a-Service covers, where the gaps lie, and what a bank or broker needs alongside it to run a complete, compliant digital asset operation. 

What is Crypto-as-a-Service? 

Crypto-as-a-Service is an outsourcing arrangement where a third-party provider gives banks and brokers access to digital asset execution, custody, and counterparty connectivity so they can launch digital asset trading services without needing to build that infrastructure in-house or to buy from individual vendors. The scope of a CaaS provider typically covers the street-side layer of a digital asset operation, managing the connections between the institution and the liquidity providers and custodians it trades and settles with. 

Crypto-as-a-Service typically comprises a bundle built around three core functions: 

• Execution access. Connectivity to liquidity providers, order routing, and trade execution. 

• Custody. Safekeeping of digital assets, often with regulatory licensing attached. 

• Counterparty connectivity. The technical and operational relationship that lets the institution trade and settle with liquidity providers and custodians. 

For an institution evaluating whether to build or buy, this is genuinely useful ground to outsource. However, taken by itself, a CaaS model only delivers part of what an institution needs to service a digital asset trading operation.

Why banks and brokers are attracted to Crypto-as-a-Service providers 

The appeal of Crypto-as-a-Service comes from three major factors: time to market, build costs, and counterparty access.  

• Faster time to market. Standing up direct connections to multiple liquidity venues and custodians, securing the relevant licensing, and building execution infrastructure from the ground up can take years. A CaaS provider dramatically compresses that timeline. 

• Lower upfront build cost. Building execution and custody infrastructure requires significant technology investment before a single client trade is ever placed. Crypto-as-a-Service defers that investment, converting a large capital outlay into an ongoing service relationship. 

• Immediate access to execution and custody. Rather than negotiating individual liquidity and custody relationships, an institution using a CaaS provider gets access to an established network of counterparties, along with the relevant regulatory licensing. 

For institutions that need to move quickly in response to client demand, competitive pressure, or a board mandate to enter digital assets, this is a reasonable decision. The question is what happens after that initial launch, once client volumes, product complexity, and regulatory scrutiny start to grow. 

The hidden operational gap in Crypto-as-a-Service-only models 

CaaS providers solve the street-side layer of a digital asset operation, covering execution, custody, and counterparty access. What they don’t solve is everything on the client-side and in the institution’s core systems. It’s a longer list than it might first appear. 

Even with a CaaS provider fully in place, the institution retains responsibility for: 

• Client account management. Onboarding, managing, and servicing individual client accounts. 

• Pricing and quoting. Building real-time, client-specific pricing with embedded spreads or markups. 

• Fee construction. Defining and applying fee and revenue models per client, client segment, or instrument. 

• Order execution oversight. Managing the full order lifecycle between the client and the street-side provider. 

• Reconciliation. Matching trades and positions across the institution’s own books and the CaaS provider’s records. 

• Allocation. Breaking down omnibus-level activity at the CaaS provider into individual client sub-ledgers. 

• Portfolio and position management. Tracking client-level positions and P&L in real time. 

• Bookkeeping. Maintaining accurate, audit-ready accounting records across client and omnibus accounts. 

• Internal system integration. Connecting the digital asset operation to core banking, compliance, and reporting systems. 

The extent of operational effort involved in these activities shouldn’t be underestimated. A provider genuinely does not see individual client accounts, calculate client-level P&L, apply an institution’s own pricing and fee schedules, or post transactions into internal systems. If this layer isn’t planned for from day one, it will surface soon after launch as a costly retrofit. Rather than being able to plan, at this point it’s more likely to be built under pressure.  

Some institutions prefer to work with more than one CaaS provider, as a way of diversifying counterparty risk. However, this also means incurring the added burden of orchestrating, reconciling, and accounting for activity across multiple trading and custody relationships at once, spanning both the client-side and the street-side. 

It’s likely that other gaps will also emerge. A single-provider setup means an institution doesn’t have an alternative venue or price comparison, which makes it harder to demonstrate best execution, and it can also mean a single point of failure. If a CaaS provider experiences downtime or a service disruption and is the sole provider to an institution, the institution’s entire digital asset operation stops, with no fallback in place.  

Since a CaaS provider is generally optimized for its initial use case, which is typically spot trading and basic custody, expanding into new products or services later tends to require rebuilding parts of the operational layer rather than simply extending it.  

None of these are reasons to avoid Crypto-as-a-Service, but they are reasons to plan the client-side and orchestration layer alongside it, rather than after the fact. 

The three layers of a digital asset operation 

A useful way to think about where Crypto-as-a-Service fits and where it doesn’t is to break a CaaS-enabled digital asset operation into three distinct layers. 

Most outsourced, integrated Crypto-as-a-Service solutions address only the middle layer – the street-side. Even prime brokerage or aggregated-liquidity models, which improve price quality by pulling from multiple liquidity sources, don’t extend into client-side portfolio management, dynamic quoting, fee construction, or post-trade accounting at the individual client level. The client-side and core functions layers remain the institution’s responsibility regardless of which street-side model it chooses. 

What Crypto-as-a-Service providers usually cover 

Crypto-as-a-Service providers generally deliver a relatively common package of solutions, although the exact features are likely to vary between operators.  

Execution access is generally part of the package but isn’t necessarily uniform across providers. Some route every order through a single liquidity relationship, while others aggregate pricing across multiple venues before routing, which tends to produce better fills for the institution’s end clients. Established CaaS providers are increasingly moving toward the latter. 

Custody arrangements may vary too. Some providers custody assets directly, under their own regulatory license. Others sit as an orchestration layer over a separate qualified custodian or custody technology provider. Either way, the outsourcing principle holds, since the institution’s digital assets end up with a regulated third party rather than in infrastructure the bank or broker built and holds itself. 

Counterparty connectivity is what ties the two together day to day. Data feeds, settlement instructions, and reconciliation formats let the institution trade and settle through the provider’s rails without negotiating and maintaining that plumbing itself. 

Even at their most sophisticated, these arrangements are all solving the same problem: getting the institution safely and efficiently onto the street-side. What sits on top of that connection, and how it reaches an individual client, is a different question. 

What banks and brokers still need to build 

The client-side and core functions responsibilities outlined above don’t have to be built all at once, but they do have to be built by someone. In most CaaS-only setups, that someone is the institution’s own technology and operations team, assembling capabilities piece by piece, rather than adopting a platform built for the purpose. 

Unfortunately, this approach tends to concentrate risk. Client-side infrastructure is rarely the first thing built when an institution launches a CaaS-based offering. More often, the street-side relationship is live, trading can start, and the client-facing plumbing gets built, or improvised, around it under time pressure. In the worst case, the institution is left handling operations manually, such as spreadsheet-based reconciliation, ad hoc fee tracking, or position data pulled together by hand at month-end, creating the risk of compliance exposure. 

There’s also a structural decision that has to be made early, because it shapes everything downstream. The institution needs to decide whether to operate on an agency (riskless principal) basis or take on principal risk through warehousing. Agency execution is the simpler starting point, as the institution passes client orders straight through and takes a fee, with limited market risk. Principal warehousing gives more control over spreads and revenue, but requires its own risk model, capital allocation, and hedging logic layered on top of the CaaS provider’s execution access.  

A CaaS provider’s offering doesn’t make this decision for the institution, and switching from one model to the other later is a rebuild, not a configuration change.

How Wyden Infinity completes the digital asset operating model 

Wyden Infinity is a digital asset trading and orchestration platform built for banks and brokers. Execution runs through its own OEMS, through an outsourced CaaS or execution provider, or both. Custody is always external, connected via API to the custodian of your choice. Whichever combination an institution uses, it’s Wyden’s unified layer that connects front, middle, and back-office workflows across the digital asset trade lifecycle. 

The parts of the operation that always stay with the institution – client order management, real-time pricing and quoting, fee and spread construction, multi-provider reconciliation and settlement, omnibus-to-client allocation, position and P&L management, and banking-grade bookkeeping – sit with Wyden Infinity, regardless of how execution is sourced. 

It’s also designed to fit an institution’s existing infrastructure, technology, and operational resilience requirements, whether that means working with a single CaaS provider, multiple providers for diversification, executing directly through its own OEMS, or a mix of all three. It connects to a broad network of liquidity venues, custodians, custody technology providers, and market data providers, with each integration built and maintained centrally, so the institution doesn’t have to manage each provider relationship separately. 

The result is a complete operating model, with Wyden Infinity as the orchestration layer that connects execution and custody to everything the institution’s clients, compliance function, and internal systems actually need. 

In practice, that coverage spans the full trade lifecycle:  

• Pre-trade. Including per-client risk and limit checks, real-time pricing and quoting with embedded spreads, and liquidity management across venues.  

• Trade. Covering client-side order management under agency or principal models and routing across liquidity providers, which – because it draws on more than one venue rather than a single CaaS counterparty – supports the kind of price competition and execution evidence a single-provider setup structurally cannot. 

• Post-trade. Handling multi-provider settlement, omnibus-to-client allocation, real-time position and P&L valuation, and banking-grade double-entry bookkeeping.  

Why “Crypto-as-a-Service + Wyden” is stronger than CaaS-only 

The clearest way to see the difference is side by side. 

A CaaS-only setup leaves every item in the left column as manual work, custom-built internal tooling, or a gap the institution doesn’t discover until it’s already scaling. Pairing Crypto-as-a-Service with Wyden Infinity closes that gap from day one, rather than retrofitting it once client volumes make manual processes unworkable. 

This is also where the case for CaaS + Wyden extends beyond a single provider relationship. Wyden Infinity is built to sit above one or more CaaS or liquidity and custody providers, so an institution that later wants to diversify counterparty risk – adding a second CaaS provider or custodian – can do so without creating a new reconciliation silo or integration project each time. The orchestration layer is already in place to absorb it.

In summary, a CaaS provider is a genuinely sound way to get a bank or broker’s digital asset execution and custody live quickly. However, institutions must also plan the client-side, orchestration, and core operational layer alongside it, rather than discovering the gap once client volumes have already outgrown manual workarounds. Wyden Infinity is built to be that unified operating platform – working with whichever CaaS provider or providers an institution chooses, or executing directly through its own OEMS. 

Whether your institution is already working with a CaaS provider or weighing its execution options more broadly, Wyden Infinity is built to complete the operating model without disrupting what’s already in place.
