# QUEX

> Secure, verifiable and any source data for smart contracts.

QUEX helps smart contracts access and verify Web2 data by using hardware-secured oracles powered by Trusted Execution Environments.

QUEX helps blockchain developers and dapps fetch and prove off-chain data by running oracle executors inside Intel TDX TEEs. It generates attestations, signs responses, and delivers certified data to contracts across multiple networks. Pools of executors handle requests and callbacks with keys confined to an encrypted VM, reducing reliance on operators and limiting manipulation.

## Products

- [QUEX Oracle](https://thegrid.id/profiles/quex): QUEX Oracle is a TEE-based data oracle for smart contracts on EVM chains. It lets contracts fetch, compute, and verify Web2 data using Intel TDX attestation, producing hardware-signed results that are verified on-chain. It supports custom data feeds and pooled executors for request handling. (Oracle, Live, Main Product)
- [TDX Measurement Verification Tool](https://thegrid.id/profiles/quex): TDX Measurement Verification Tool is a web utility that calculates MRTD and RTMR measurements for Intel TDX Trust Domains from selected firmware, hardware, and software inputs. It helps developers validate configuration measurements when preparing TDX environments. (Developer Tooling, Live)
