For many fintech teams entering crypto, a modular infrastructure strategy feels like the safest choice. One provider handles custody, another manages AML, a separate partner provides liquidity, while fiat rails sit somewhere else in the stack.
At first, this architecture looks scalable and flexible. In reality, it often becomes the main source of operational friction.
Every additional vendor introduces another integration layer, another SLA, another support process, and another dependency that engineering teams cannot fully control. Most failures in crypto products do not happen inside individual systems — they happen between them.
A provider changes an API version without notice. AML checks get delayed during peak onboarding periods. Wallet synchronization fails because two services process transaction states differently. Suddenly, product teams spend more time coordinating vendors than shipping features.
The Synapse collapse in 2024 demonstrated how dangerous multilayered financial infrastructure can become. The reported $85 million discrepancy between customer balances and actual partner bank funds was not caused by a single catastrophic failure, but by operational fragmentation across interconnected systems.
This is exactly why the industry is moving toward integrated WaaS (Wallet-as-a-Service) and CaaS (Crypto-as-a-Service) models.
Different providers solve different parts of the infrastructure problem:
- Cobo focuses heavily on WaaS, offering MPC wallet infrastructure and support for 80+ blockchains. However, trading and liquidity layers still require external integrations.
- Kraken Institutional is primarily CaaS-oriented, providing execution and trading APIs without wallet orchestration.
- Fireblocks combines custody, AML, DeFi connectivity, and settlement infrastructure into an enterprise-grade stack, though implementation complexity remains high.
- WhiteBIT approaches the market with a more deployment-focused model, combining WaaS and CaaS with embedded AML, cross-chain support, and white-label infrastructure for EMIs and neobanks.
From an engineering perspective, infrastructure consolidation is no longer just about convenience. It directly impacts time-to-market, operational overhead, and system reliability.
The biggest misconception in fintech today is that competitive advantage comes from features. Features are replicated quickly. Infrastructure efficiency is much harder to copy.
In practice, the companies that scale fastest are usually the ones reducing dependencies — not adding more of them.
