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.
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 to claim available rewards, and see the Guardian transition for the Ethereum timeline.
