      summary: List chains supported by LI.FI Earn
      description: 'Returns the list of chains that have at least one Earn vault available. Derived from current vault data.


        **This endpoint is scoped to LI.FI Earn (vaults).** Only chains where Earn currently has indexed vaults are returned — it is not a general list of all chains the LI.FI platform supports, and it should not be used to determine SDK / Swaps / Bridges chain coverage.


        If you are integrating Swaps or Bridges (via the LI.FI SDK or the main API), call [`GET https://li.quest/v1/chains`](/api-reference/get-information-about-all-currently-supported-chains) instead. That endpoint returns every chain supported by the LI.FI Aggregation API.
