TL;DR:
Web3 teams waste time and money stitching together fragmented infrastructure, juggling multiple SDKs, inconsistent APIs, brittle auth flows, and scattered dashboards.
Uniblock offers a unified SDK and orchestration layer that connects over 1,500 Web3 APIs and more than 100 chains through a single interface. It routes requests to the fastest, cheapest, and most reliable provider.
By abstracting away infrastructure sprawl, Uniblock reduces integration time by 80%, lowers costs, simplifies onboarding, and provides teams with the flexibility to experiment, scale, and ship faster, without getting bogged down in SDK sprawl or vendor overhead.
With growing infrastructure complexity across chains, the Web3 ecosystem will depend on unified coordination layers like Uniblock to scale efficiently.
In the rush of Web3 innovation, crypto builders must navigate a thicket of fragmented tools and networks. A decentralized ecosystem naturally spawns a myriad of blockchains, APIs, and SDKs. The result is a Web3 tech stack that often feels more siloed than unified.
Early internet networks faced a similar problem until TCP/IP connected them into one web. Today, many in the industry argue that Web3 is at a comparable inflection point: it needs convergence layers to abstract away complexity.
This article explores infrastructure sprawl, Uniblock’s “one API” approach, the structure of its unified stack, developer and business benefits, and the role of orchestration layers in scaling decentralized ecosystems.
The Fragmented Web3 Stack: A Growing Pain
Web3 development currently involves a patchwork of chains and services. Developers must grapple with multiple programming languages and frameworks depending on the blockchain or protocol they target.
Building across Web3 often requires proficiency in Web3.js for some chains, Solidity for Ethereum and EVM-compatible chains (such as Polygon, BNB, Avalanche), Move for Aptos or Sui, and Rust for Polkadot or Solana. For developers building serious decentralized applications, the stack quickly becomes a tangle of APIs and SDKs, each solving part of the problem but none working together natively.
Take a standard dApp: to handle wallet connection, data reads, NFT metadata, and real-time user notifications, teams often wire up WalletConnect, Alchemy, Covalent, Moralis, and Push Protocol. Each tool brings its own SDK, rate-limit schema, authentication layer, and version lifecycle. As a result, every new project ends up reinventing integration logic, which a unified platform could handle centrally.
While the Web2 tech stack is complete, the API data layer is missing in Web3. Web2 benefited from mature middleware and cloud platforms; Web3 is still maturing, and it shows in the daily struggles of developers dealing with fragmented components.
Developer teams are forced to become backend coordinators. They spend more time debugging glue code than shipping features. And while composability is still the north star, what’s missing is an abstraction layer that handles orchestration for them.
The Real Cost of Infrastructure Sprawl
Tooling sprawl in Web3 is inconvenient and structurally inefficient. Each service added to a stack means a new API contract, a separate SDK, custom error handling, and ongoing version maintenance.
This fragmentation carries real costs and consequences. For developers and startups, managing a sprawling set of infrastructure tools can dramatically slow down time to market. In practice, teams often spend months building and maintaining their own ad hoc API layers to stitch together disparate services.
Every new blockchain integration or data source might require custom connectors and extra engineering work, diverting resources from core product development. In an industry where speed is a competitive edge, such delays and expenses are painful.
Even worse, this fragmentation damages user experience. An inconsistent state across wallets, data providers, and notification channels can lead to app crashes, incorrect UI, or worse, loss of funds. Fragmentation can stifle user adoption.
A clunky user experience results when dApps on different chains can’t communicate, or when users must manage multiple wallet accounts for various platforms. Liquidity and assets are confined to “walled gardens” on individual networks, limiting the scope of markets. All these issues point to the same conclusion: Web3’s siloed growth, if left unchecked, will continue to stall progress until a more unified approach emerges.
Uniblock is built to solve that exact problem, not by replacing existing tools, but by giving developers a coherent access layer to connect and manage them.
Uniblock: The Unified Access Layer for Web3 Infra
If middleware is the answer to Web3’s fragmentation, how is Uniblock different from the many infrastructure providers already in the space? Traditional Web3 middleware solutions have tended to solve one slice of the problem at a time. For instance, one service might offer blockchain node access (RPC endpoints), another specializes in indexing onchain data (subgraphs and APIs for specific chains), while others handle tasks such as wallet integrations or oracle feeds.
A dApp team might use Infura for Ethereum nodes, The Graph or Covalent for querying blockchain data, and Chainlink for price oracles. Essentially, developers became their own integrators, stitching these services together. This not only required juggling multiple vendor relationships but also meant the onus of evaluating, switching, and load-balancing between providers fell on each developer team.
Uniblock flips that paradigm by acting as a unified orchestration layer over many infrastructure services. The platform aggregates over 1,500 API endpoints from more than 50 providers spanning 100+ blockchains and exposes them through a single interface. In concrete terms, a developer using Uniblock gets one account and one API key that grants access to a vast array of Web3 functionality that would normally require dozens of separate integrations.
Need NFT metadata, a Solana transaction history, and the latest Ethereum gas prices? In a traditional setup, that might involve three different SDKs or APIs. With an orchestration platform like Uniblock, those all become calls to one service. By consolidating these capabilities, Uniblock positions itself not as another narrow middleware tool, but as an API-of-APIs, essentially middleware for all the other middleware.
Importantly, Uniblock is not just a simple aggregator but an intelligent router. Unlike a basic API gateway, it doesn’t blindly pass through calls to a single fixed provider. The platform uses artificial intelligence to dynamically route each request to the fastest, cheapest, and most reliable backend option available.
This is a key distinction from traditional middleware. In the Web2 world, companies like MuleSoft and Apigee proved the value of API management layers, achieving billion-dollar exits by simplifying enterprise integrations. Uniblock is bringing a similar concept to Web3’s chaotic landscape, but with the added twist of real-time optimization across providers.
How It Works: A Modular SDK for Multi-Service Coordination
Uniblock is a modular, service-agnostic SDK that abstracts the mess beneath the Web3 stack. Developers integrate it once and gain streamlined access to wallets, data, NFTs, and more, without needing to implement each third-party tool separately.
Instead of directly importing five different SDKs and managing their unique quirks, teams interact with one standardized interface. Configuration is handled via Uniblock’s dashboard, where developers select the services they want, like WalletConnect for wallet connections, Covalent for token balances, or Push Protocol for real-time alerts.
Behind the scenes, Uniblock handles:
Routing: Requests are dynamically directed to the correct service or fallback based on configuration and availability.
Authentication & Rate Limits: Uniblock normalizes how keys are stored and requests are throttled, eliminating vendor-specific complexity.
Chain Support: Multichain requests are abstracted so developers don’t need to build separate logic for each network.
Fallback Logic: If one provider is unavailable, Uniblock reroutes to an alternate, preserving app functionality with minimal downtime.
Developer Benefits in Real Terms
The immediate appeal of a unified infrastructure like Uniblock is developer efficiency. Engineers can integrate once with Uniblock and instantly have access to a buffet of Web3 capabilities. This dramatically reduces the integration overhead for multi-chain or multi-service applications. In practical terms, this speeds up development cycles. Features that might have taken months to implement (waiting on backend integrations, dealing with each provider’s quirks) can be completed in weeks or days.
A unified API also lowers the learning curve for developers. Instead of mastering many different SDKs and querying conventions, teams can learn one system and apply it everywhere. This is particularly valuable for onboarding Web2 developers into Web3, because it abstracts away much of the esoteric complexity that would otherwise require niche expertise.
There’s also a significant cost advantage. By eliminating redundant infrastructure work, startups save on developer hours and ongoing maintenance. Projects have saved over $250k+ in costs, and this showcases how expensive “infra sprawl” can get. Uniblock’s model, offering 1500+ APIs at wholesale pricing through one account, spreads those costs over many users, achieving economies of scale.
Moreover, intelligent routing ensures that projects always receive the most cost-effective option for a given request without requiring manual effort. Businesses also benefit from simplified vendor management. Instead of negotiating and managing contracts with a dozen providers, they deal with just one platform.
For developers, an underrated benefit is focus. Using an orchestration layer frees teams to focus on their product’s unique logic and user experience, rather than plumbing infrastructure. This can catalyze innovation. Teams can try new features or chain integrations on a whim since the marginal cost of experimenting is low. Want to add support for an emerging Layer 2 or a new NFT data API? If it’s already integrated in the unified platform, it might be a single API call away.
Finally, businesses building on Web3 gain strategic flexibility from such unified layers. They are less likely to get “locked in” to any single provider or chain. If a better, faster protocol comes along, the orchestration layer can route to it, and the application can migrate behind the scenes. This makes the overall ecosystem more dynamic and competitive, which benefits everyone.
Market Landscape: Fragmentation at Scale
Web3’s infrastructure stack continues to expand, but with expansion comes entropy. Every new chain, protocol, or tooling solution adds another moving part to the already fragmented backend. For developers, building even a simple application means wrangling multiple systems just to get basic functionality live.
The rise of unified platforms like Uniblock hints at a broader trend: Web3 is entering an orchestration phase. In the evolution of any technology stack, there comes a point where plugging pieces together ad hoc no longer scales, and a higher-order layer of coordination is needed.
Developer interest hasn’t slowed, downloads of developer tools that enable users to interact with crypto have surged 12-fold, from 1.9 million in December 2020 to 23.8 million in May 2025. This level of growth indicates a few key factors: a surge in onchain activity, tooling, and infrastructure demand is going to increase, and cross-chain complexity will continue to get simplified as developers are forced to seek uniform SDKs and routing engines to build on these networks.
Another interesting thing to note is that Established Developers (those in crypto for 2+ years) are at all-time highs, growing 27% YoY and committing 70% of code commits. This fragmentation becomes more urgent when viewed against the backdrop of machine-driven application growth. As APIs become the connective tissue of AI-driven applications, reliance on APIs is skyrocketing.
The global AI API market size was estimated to be $48B in 2024 and is projected to reach $246B by 2030, growing at a CAGR of 31.3% from 2025 to 2030. AI APIs accelerate digital transformation by embedding intelligent capabilities, such as real‑time analytics and automation, directly into software workflows. They enable organizations across industries to adopt AI quickly and cost‑effectively.
Gartner finds that over 80% of organizations use APIs internally, and 70% leverage external APIs. Forrester projects that by 2025 end, APIs will serve as the primary enabler for digital strategy at 70% of enterprises. APIs are no longer an integration tool; they are the interface layer of autonomous applications. In this new AI reality, the ability to orchestrate API interactions across chains and providers becomes foundational. That is precisely what Uniblock delivers: one access point, intelligent routing, and a performance-aware interface that scales with machine-generated demand, not just human interaction.
From Fragmented Chaos to Cohesive Infrastructure
As Web3 ventures look toward mass adoption, simplifying infrastructure is emerging as the next critical frontier. The past decade was about proving what blockchains and smart contracts could do; the next will be about making those capabilities easy and scalable to use.
Uniblock’s unified infrastructure layer is advancing this shift, not by replacing the rich variety of Web3 services, but by orchestrating them for greater impact. This approach could enable a more coherent, efficient, and usable decentralized ecosystem, one where builders build, and complexity stays out of the way.
