5 Critical Issues Web3 Builders Face – And How New Gen Tech Solves Them

Web3 is scaling faster than ever. But builders, CTOs, and project founders still face major roadblocks that can instantly make or break their DApps. From high costs and deployment delays to data security risks. The challenges are real, but next-gen technology is here to change the game. With the right infrastructure, every challenge becomes a chance to scale — securely and fast. 

In this article we’ll break down the five biggest challenges Web3 builders face today — and how new solutions, Intelligent Data Oracles powered by cryptographic security and verifiable computations, are making Web3 stronger than ever. 

Issue #1: Manipulated Data Can Destroy Your Smart Contract

• Tampered price feeds trigger mass liquidations in lending markets.
• AI-powered dApps receive manipulated inputs, leading to faulty automation.
• Incorrect valuations in RWA tokenization cause compliance and huge financial risks.

The FIX: Hardware-Based Security & Cryptographic Attestation
With Trusted Execution Environments (TEEs) powered by Intel TDX ( (Trust Domain Extensions – the specific TEE technology implemented in QUEX), builders can now access cryptographically signed, tamper-proof data—generated and verified directly at the hardware level—eliminating the need to trust oracle node operators or other intermediaries.

• Verifiable, cryptographically signed data before it reaches your smart contract

• Eliminates risks of oracle collusion, API overrides, and data tampering

• Ensures off-chain data was processed exactly as requested, without modifications

The real next-gen solution offers security at the level of the underlying TDX chips, eliminating the need to trust an oracle’s team, oracle node operators, or any other intermediaries.

Issue #2: Limited & Predefined Data Feeds Are Holding Back Your Innovation

• A DeFi protocol might need a customizable set of price feeds or institutional-grade risk modeling for on-chain derivatives.
• A sports prediction platform might require exclusive, real-time athlete performance data. 
• An AI-powered Web3 app might rely on proprietary analytics that no other oracle provides.

The FIX: Fully Customizable Data Access with Any Off-Chain Sources
Instead of being restricted to predefined feeds, new-gen oracles enable Web3 builders to fetch data from any off-chain source – ensuring full flexibility, security, and scalability.

How It Works:
– Direct HTTPS Queries – Fetches data from any API, including AI models, financial databases, and proprietary sources.
– TDX-Powered Secure Processing – Ensures that off-chain data is fetched, processed within a TEE, and cryptographically signed before being delivered on-chain.
– Flexible Data Processing – Allows custom transformations, filtering, and aggregation before delivering final results to smart contracts.

Now Web3 builders no longer have to choose between flexibility and security and can start building without data limitations. Any off-chain data can now be custom – sourced, and seamlessly integrated into smart contracts.

Issue #3: Data Processing On-Chain is Costly & Limited

• DeFi platforms need post-processing for pricing, risk modeling, and collateral adjustments.

• AI-powered dApps require structured, pre-computed analytics before smart contract execution.

• Prediction markets need finalized, provably fair results—without heavy on-chain operations.

The FIX: Verifiable Computation & Hardware-Secured Data Processing
With TDX-powered next-gen oracle technology, builders can now process, compute, and verify data off-chain in a cryptographic environment – ensuring that only the final, secure results reach the blockchain.

• Lower gas costs by moving computational-heavy operations off-chain

• Secure, cryptographic verification ensures that off-chain results remain tamper-proof

• More advanced, scalable data processing for AI, DeFi, and cross-industry Web3 applications

For the first time, next-gen oracles provide smart contracts with verifiable, structured data, boosting efficiency and reducing gas costs. With TEE-powered solutions, accessing and verifying off-chain data is now as seamless as in Web2.

Issue #4: Scaling Across Multiple Networks Requires Rebuilding Infrastructure

•  DApp developers must reimplement critical components—like oracles, co-processors, and data layers—when expanding to new chains.

• Infrastructure fragmentation slows down cross-chain adoption and increases engineering overhead.

• Web2 integrations, analytics, and AI services require custom workarounds on every new network.

The FIX: Infrastructure Reuse Across Web2 and Web3
Next-gen solutions like QUEX enable developers to reuse existing Web2 and Web3 infrastructure across any blockchain—eliminating the need to rebuild core systems from scratch.

How It Works:

• Unified Infrastructure Layer – Connects oracles, APIs, AI co-processors, and data availability layers through a single interface.
• Plug-and-Play Integration – DApps can reuse data access logic and avoid redeveloping oracle infrastructure when expanding to new networks.
• Confidential Computing Proofs – Enabled by TDX-powered TEEs, Ensures integrity and attestation for all data before it reaches smart contracts..

Instead of reinventing infrastructure for every new chain, developers can now scale faster, reduce costs, and stay focused on innovation.

Build once. Deploy anywhere.

Issue #5: Delayed & Inefficient Data Updates Are Holding Web3 Back

Web3 applications require accurate, real-time data to function effectively. But most oracles rely on fixed update intervals, which can be:

• Too slow for DeFi trading & lending—leading to missed arbitrage opportunities or inaccurate liquidations.
• Too expensive for high-frequency applications—forcing builders to pay for updates they don’t always need.
• Inefficient for AI-driven dApps—limiting the ability to process real-time analytics.

The FIX: On-Demand, Real-Time Data Integration Under Your Control 

Instead of pushing batch updates at predefined intervals, New-gen oracles enable builders to fetch secure, verifiable off-chain data exactly when needed through:

• Pull-based queries – fetch data only when needed, reducing unnecessary on-chain updates and optimizing gas efficiency. 

• Customizable request structure – allows developers to define exact endpoints, parameters, and post-processing logic to retrieve and shape data as needed. 
• Secure HTTPS-based retrieval – enables access to any external Web2 source via HTTPS, with each response cryptographically signed in a TEE for on-chain verification.

QUEX, which recently became the first TDX-powered oracle to go live in production, exemplifies this overall approach. Built on the latest TEE advancements, its system enables smart contracts to access, compute, and validate any Web2 data for on-chain use across any blockchain. The security operates at the processor level itself, eliminating the need to trust the oracle team, node operators, or other intermediaries.

By eliminating wasteful updates and rigid oracle cycles, developers can now optimize data retrieval for security, cost-efficiency, and real-time performance. This represents a fundamental shift from the traditional oracle model toward more flexible, developer-controlled data access.
