For banks and brokers looking to launch a digital asset offering, outsourcing to a Crypto-as-a-Service (CaaS) provider looks like the obvious shortcut. Instead of building trading and custody infrastructure from scratch, an institution can plug into a regulated provider, outsource execution and custody, and be live with a crypto offering in a fraction of the time.
But there’s a blind spot in this plan that most institutions don’t discover until they’re already committed to a CaaS provider: outsourcing execution and custody only outsources part of the operation.
What is the digital asset client-side gap?
Everything that happens between the institution and its own clients – pricing, quoting, fee management, order handling, position keeping, reconciliation, reporting – remains entirely the institution’s responsibility, no matter how sophisticated the CaaS provider. A CaaS provider takes care of the street-side of a digital asset business, handling the relationship between the institution and the liquidity providers and custodians it trades and settles with. It doesn’t cover the client-side, meaning the relationship between the institution and the customers it serves. The need for a client-side layer doesn’t disappear just because a bank or broker chose to outsource. It must be built, owned, and operated by the institution itself – and if it isn’t planned for from day one, it becomes an expensive, disruptive retrofit later.
This is the piece of the puzzle that a lot of banks and brokers underestimate, and it’s worth setting out clearly before any institution signs a CaaS agreement.
What the digital asset client-side gap means for banks and brokers
The commercial logic behind CaaS is straightforward. Building trading and custody infrastructure in-house is capital-intensive, slow, and requires licenses and risk controls that most banks and brokers don’t want to develop for a first foray into digital assets.
A CaaS provider removes that burden. It holds the regulatory licenses, connects to liquidity, and custodies the assets, letting an institution go live with a crypto offering quickly and with a lower upfront cost.
The utility of this service explains why CaaS has become a popular entry point into digital assets for banks and brokers. However, many institutions quickly encounter issues when they discover that the role of their CaaS provider is narrower than initially assumed. A CaaS provider manages the relationship between the institution and its trading and custody counterparties, while the institution retains full responsibility for managing relationships with its clients. Client account management, pricing and quoting, fee and revenue construction, order execution on the client side, post-trade reconciliation and allocation, portfolio and position management, and bookkeeping across client and omnibus accounts all remain squarely with the institution – regardless of how capable the CaaS provider is on the street-side.
The complexity compounds further if an institution decides, sensibly, to diversify across more than one CaaS provider to spread counterparty and concentration risk. At that point, the institution isn’t just responsible for its own client-side operation – it must also orchestrate, reconcile, and account for multiple trading and custody relationships at once, including tasks like liquidity management and settlement that span both sides of the business.
The three layers of a digital asset operation, and where the responsibility sits
It helps to think of a digital asset operation as three distinct layers rather than a single build-or-buy decision.
The first is the client-side, which covers everything that happens between the institution and its own clients. This includes client order receipt and management, real-time pricing and quoting, fee and spread management per client, client P&L and position management, post-trade settlement and allocation to client accounts, and the regulatory evidence – such as best execution reporting – that proves clients were treated fairly.
The second is the street-side, meaning everything that happens between the institution and its liquidity providers and custodians. This is where CaaS providers operate, covering liquidity provider connectivity and order routing, street-side execution and fills, custody and settlement, street-side position tracking, and the regulatory licensing required for brokerage and custody activity.
The third layer sits underneath both, handling the core functions that tie everything together. This includes integration with core banking and internal systems, management and reconciliation across multiple liquidity venues and custodians, banking-grade accounting and bookkeeping across the full trade lifecycle, workflow automation and audit trail, and regulatory and compliance reporting.
Most CaaS and other integrated street-side solutions address only the second layer. Even prime brokerage or aggregated-liquidity models, which improve price quality by pulling from multiple sources on the street-side, don’t change this picture – they still leave the entire client-side operational stack untouched. Aggregating liquidity is not the same as managing client portfolios, constructing client-specific pricing, or producing post-trade accounting at the individual client level.
The risks for banks and brokers
Treating a CaaS provider as a complete digital asset solution creates strategic exposure in several places, and the risks tend to be underappreciated precisely because they aren’t visible until the business has scaled.
No client-side management. The most consequential is the absence of client-side management altogether. A CaaS or integrated provider has no visibility into individual client accounts. It cannot calculate client P&L, apply an institution’s own pricing and fee schedules, post transactions to client sub-ledgers, or integrate with core banking systems. Without this layer, an institution cannot systematically capture, audit, or report on its own trading revenue. Left unaddressed from the outset, this operational layer becomes a costly retrofit once the business has grown. It also means the institution can’t make a foundational decision about its own risk model – whether to operate on an agency (riskless principal) basis or take on principal warehousing – a choice that directly shapes market risk exposure, capital requirements, and the ability to manage spreads for profitability.
No best execution compliance. Best execution compliance is another exposure that grows more serious as digital asset regulation matures. Frameworks such as MiCA in the EU, FinSA in Switzerland, and VARA in the UAE increasingly extend best execution obligations to digital assets. Routing every client order through a single liquidity provider that is also the sole counterparty makes it structurally impossible to demonstrate best execution: there’s no independent price competition, no alternative venue, and no way to show clients got a fair price. As scrutiny of digital asset conduct increases, institutions that built their execution infrastructure around one provider are the ones most likely to face costly remediation.
No operational resilience. Operational resilience follows a similar logic. A single provider is a single point of failure. If that provider experiences downtime, a system issue, or a market disruption, the institution’s entire digital asset operation stops, with no fallback or alternative routing available. Regulation such as DORA in the EU explicitly requires institutions to demonstrate operational resilience and continuity of service – a requirement a sole-provider model cannot satisfy by design. Regulators are already examining single-provider dependencies in digital asset infrastructure, and this scrutiny is only likely to increase.
No custody diversification. Custody concentration raises a related concern. Holding all client assets with a single custodian creates fiduciary and counterparty risk, and regulatory expectations are moving toward custody diversification. A single-provider model makes diversification structurally difficult, since every additional custodian requires its own integration project, with the institution still responsible for aggregating and reconciling across them.
No scalability or product expansion. Scalability is often underestimated too. CaaS providers and integrated platforms are typically optimized for the use cases they launched with – spot trading, agency execution, basic custody. As digital asset markets mature toward staking, tokenized assets, real-world assets, or structured products, growth becomes a multi-vendor infrastructure program that institutions either plan for early or build reactively at significantly higher cost and complexity later.
Loss of vendor control. Finally, there’s the question of vendor control and multi-provider complexity. Outsourcing to a single CaaS provider locks an institution into that provider’s product roadmap, pricing, and pace of development. The instinctive fix – adding a second CaaS provider – doesn’t solve this problem so much as multiply it. Without an internal orchestration layer, every additional provider brings a new integration dependency, a new operational silo, and a new source of reconciliation complexity. Diversifying providers without accumulating this kind of integration debt requires an orchestration layer to already be in place, not bolted on after the fact.
What a complete digital asset operation actually requires
Put together, running a compliant, scalable digital asset business requires far more than street-side execution and custody. It requires:
- Real-time, per-client pre-trade risk checks and balance controls
- Live client pricing and quoting with fee and spread markups built in
- Fee, spread, and revenue management by client, client group, or instrument
- Full order management across both agency and principal trading models
- Smart order routing and best-execution evidence across multiple providers
- Automation and reconciliation across multiple liquidity and custody relationships
- Allocation from omnibus structures down to individual client sub-ledgers
- Real-time client position and P&L management
- Immutable, banking-grade double-entry bookkeeping
- Audit-ready reporting for regulators
- The ability to add or remove liquidity and custody providers as the business evolves, without renegotiating the institution’s entire technology stack each time
None of this is optional, and none of it is delivered by a CaaS provider. It’s the layer that makes a digital asset offering actually usable, auditable, and scalable inside a regulated institution.
Closing the gap: digital asset client-side orchestration by Wyden in a CaaS setup
This is precisely the layer Wyden Infinity is built to deliver. Wyden Infinity is a unified digital asset trading and orchestration platform designed specifically for banks and brokers, serving as the central layer that connects, automates, and manages every part of the trade lifecycle – from client order intake through to post-trade bookkeeping and regulatory-grade audit trail reporting.
Critically, Wyden Infinity isn’t a competitor or a replacement for a CaaS provider – it’s built to work alongside one, or several. Whether an institution works with a single CaaS provider, insources trading and custody, or combines multiple providers for resilience and diversification, Wyden Infinity delivers the client-side and core management layer every regulated institution needs, independent of which street-side model is chosen. On the pre-trade side, this includes per-client risk and limit checks, real-time pricing and quoting with embedded spreads, and treasury and liquidity management across venues. On the trade side, it covers client-side order management for both agency and principal models, smart order routing across multiple liquidity providers, best-execution evidence generation, and execution styles ranging from RFQ to TWAP and algorithmic trading. On the post-trade side, it handles multi-provider settlement, sub-ledger allocation, real-time position and P&L valuation, and banking-grade double-entry bookkeeping, integrated directly with core banking systems.
Wyden Infinity connects to more than 65 liquidity venues, custodians, and custody technology providers, with every integration built and maintained by Wyden rather than by the institution’s own engineering team. That removes the operational overhead of managing provider connections independently and gives institutions the freedom to add, remove, or diversify across providers as their digital asset business grows, without having to rebuild their infrastructure each time.
The choice facing banks and brokers isn’t really “CaaS or build it yourself.” A CaaS provider solves the street-side of a digital asset operation efficiently and well. What it doesn’t solve – client account management, pricing, fee construction, order handling, reconciliation, and reporting – is the layer that determines whether a digital asset offering is genuinely compliant, resilient, and scalable over time. Institutions that plan for this layer from day one avoid an expensive retrofit later. The right question isn’t whether to work with a CaaS provider, but which one – or which combination – sits alongside a proper orchestration layer to complete the stack.
