Start with the NEUS JavaScript SDK for proof creation, hosted handoff, polling, and private proof access. The JavaScript SDK is the primary client surface for custom browser and app integrations. It wraps verification creation, deterministic signing helpers, hosted verify handoff, proof polling, and widget exports in one package.

​
What the SDK Covers

Create & Poll Proofs

Submit verification requests, standardize signing, and poll async proof status.

Authentication Helpers

Use hosted login and auth code exchange guidance for lower-friction browser flows.

Verification Patterns

Choose reuse, fresh proof, or gate-check strategies based on policy and UX needs.

Error Handling

Handle retries, hosted flow failures, interactive verifier handoff, and private proof auth.

​
