# Light Nodes (Retired)

> Status of the former Sophon light-node programme

<Warning>
  Sophon light-node operating software has been retired. Do not deploy, upgrade, or
  pay a provider to run a Sophon light node for Guardian reward eligibility.
</Warning>

Sophon light nodes previously used Avail light-client technology for data
availability sampling on the Sophon Chain. Guardian reward eligibility was tied to
node operation and delegation during that phase of the programme.

As part of the chain wind-down, software operation, uptime, and delegation are no
longer required. Guardian holders continue to receive rewards according to the
original schedule.

Use [claim.sophon.com](https://claim.sophon.com) to claim available rewards, and see
the [Guardian transition](/nodes/our-infra) for the Ethereum timeline.
