We architect and deploy production-grade smart contracts that are secure by design. Every contract undergoes a multi-stage audit process, including automated analysis with Slither and manual review by our senior security engineers, before deployment to mainnet.

ENTERPRISE-GRADE SECURITY & PERFORMANCE
Core Capabilities of Our TEE Oracle Development
We architect and deploy verifiable data feeds with hardware-enforced security, delivering the tamper-proof integrity and high-frequency data your DeFi, RWA, and institutional applications require.
01
Hardware-Enforced Data Integrity
Leverage Intel SGX or AMD SEV-SNP TEEs to cryptographically prove that your oracle data is sourced, computed, and signed within a secure, isolated environment. Eliminate single points of trust and protect against node operator collusion or compromise.

Architectural Comparison
TEE Oracle vs. Traditional Oracle Architectures
A technical breakdown of how our TEE-based attestation service fundamentally improves security, cost, and reliability over conventional oracle designs.
| Architectural Feature | Traditional Oracle | Chainscore TEE Oracle |
|---|---|---|
Data Integrity & Tamper-Proofing | Relies on node operator honesty and consensus; vulnerable to data manipulation. | Cryptographically attested within hardware-secured enclaves (e.g., Intel SGX). |
Trust Model | Decentralized trust across node operators; requires economic staking and slashing. | Trusted hardware root of trust; eliminates need for staking and complex cryptoeconomics. |
Latency to On-Chain Finality | High (seconds to minutes) due to consensus and aggregation delays. | Low (< 2 seconds); single, verifiable attestation posted directly. |
Operational Cost Structure | High, continuous costs for node incentives, staking, and gas fees for aggregation. | Predictable, low-cost model; pay for attestation compute, not consensus overhead. |
Attack Surface | Large: Sybil attacks, data source manipulation, consensus exploits. | Minimal: Reduced to the security boundary of the TEE hardware and remote attestation. |
Development & Integration Complexity | High: Must integrate oracle client, manage staking, and handle consensus failures. | Low: Simple API call; smart contract verifies a single cryptographic attestation. |
Time to Production Deployment | 6-12 weeks for secure integration and testing. | 2-4 weeks with our SDK and deployment templates. |
Audit & Compliance Readiness | Difficult to prove data provenance for regulators. | Inherently auditable; hardware attestation provides a verifiable chain of custody. |

Our Development & Integration Process
A structured, security-first approach to integrating verifiable off-chain data into your smart contracts, minimizing risk and accelerating your time-to-market.
01
Architecture & Requirements Review
We conduct a deep technical assessment of your data feeds, smart contract architecture, and security requirements. This phase defines the TEE attestation model, data formats, and integration points.
02
TEE Environment Setup & Hardening
Provisioning and securing the Trusted Execution Environment (Intel SGX/AMD SEV). We implement secure boot, remote attestation protocols, and network isolation to create a verifiable compute enclave.
03
Adapter Development & Attestation Logic
Building the custom data adapters that fetch, parse, and format external API data within the TEE. We develop the cryptographic attestation proofs that guarantee data integrity to the blockchain.
04
On-Chain Verifier & Smart Contract Integration
Deploying the on-chain verifier contract that validates TEE attestations. We then integrate this verifier with your application's core smart contracts for seamless, trust-minimized data consumption.
05
Security Audit & Penetration Testing
The entire attestation stack undergoes rigorous review. This includes smart contract audits, TEE side-channel analysis, and adversarial testing of the data pipeline before mainnet deployment.
06
Deployment, Monitoring & SLA Activation
We manage the production deployment of your attestation service, establish 24/7 monitoring for data freshness and TEE health, and activate the agreed-upon service level agreements (SLAs).

Frequently Asked Questions
Get clear answers on how our TEE-based oracle attestation service works, its security, and how it integrates with your project.
Traditional oracles rely on consensus among nodes, which can be vulnerable to collusion or Sybil attacks. Our service uses Trusted Execution Environments (TEEs) like Intel SGX to cryptographically prove that data was fetched from a specified API and processed by an unaltered, audited code module. This provides tamper-proof data integrity from source to on-chain delivery, eliminating the need for trust in node operators.
