# Signalite Partner Docs

> Integrate sHLP into wallets, vault pages, and mobile apps using the Signalite API and SDK.

Signalite is a liquid yield product for sHLP. Partners integrate through the hosted API for state and action quotes, and through `@arc/shlp-sdk` for typed reads, readiness checks, and transaction sending.

<Warning>
  These docs describe the partner sandbox. They are not a public launch announcement, audit report, or legal product disclosure.
</Warning>

## What partners can build

## Core rule

Every partner app must call `/api/v1/health` before showing write actions.

Use `health.ready` and SDK readiness helpers as the source of truth. Do not infer deposit readiness from static config or UI copy.

<Steps>
  <Step title="Read health">
    Fetch `/api/v1/health` and block write actions if the relevant readiness flag is false.
  </Step>

  <Step title="Read product state">
    Fetch `/api/v1/vault`, `/api/v1/config`, and user-specific `/api/v1/position`.
  </Step>

  <Step title="Build action quote">
    Use an action endpoint such as `/api/v1/actions/deposit/quote`.
  </Step>

  <Step title="Send returned transactions">
    Send approval requirements first, then the primary transaction.
  </Step>
</Steps>
