# Guardian Transition

> Guardian NFTs and node rewards during the Sophon Chain wind-down

<Warning>
  The Sophon Chain is being wound down. Light-node software has been retired, and
  Guardian holders no longer need to run software, maintain uptime, or delegate
  their NFTs to continue receiving rewards.
</Warning>

The Guardian reward programme continues on its original schedule. Guardian NFT
holders receive a pro-rata share of **20% of the original 10 billion SOPH supply
over three years**.

## What holders need to do

* Check [claim.sophon.com](https://claim.sophon.com) for outstanding node rewards.
* Do not manually move or bridge the Guardian NFT.
* Withdraw any liquid SOPH or other assets that remain on the Sophon Chain.

Under the announced migration process, Guardian NFT transfers are locked on Sophon
and the same number of NFTs will be recreated on Ethereum in the same holder wallet.
Rewards remain on Sophon through
**September 29, 2026 at 00:00 GMT**, then continue on Ethereum.
