Note all applications using NexaID SDKs are interacted with NexaID, a.k.a., decentralized attestors, where the attestations are generated in a decentralized process with a high hardware security level. With the vision of creating a decentralized data verification and computation network, NexaID provides developer tools to help applications leverage zkTLS capability from the network attestors. * For web-based applications, we recommend to use the **Network-JS-SDK** (see the [DApp Integration Guide](/docs/build/dapp-integration/example) ). This is the most straightforward tool that allows end users to create zkTLS attestations through this SDK. Note the end user is required to install [NexaID extension](/docs/build/extension/prerequisites) to perform the zkTLS session with the network attestor. ## Build with NexaID SDKs
