Guardian NFT holders retain a pro-rata share of 20% of the original 10 billion SOPH supply, distributed over 156 weeks (three years).

​
What changed

The reward allocation and duration continue, but the operating requirements have been simplified during the Sophon Chain wind-down:
  • light-node software is retired;
  • uptime is no longer a reward requirement;
  • Full Node or Light Node delegation is no longer required;
  • holders do not need to migrate Guardian NFTs manually.
The previous Full Node, Light Node, participation-bonus, uptime, and operator- commission calculations are therefore no longer instructions a Guardian holder must follow.

Claiming rewards

Use claim.sophon.com to view and claim available reward streams.
  • Rewards vest and are claimed on Sophon through September 29, 2026 at 00:00 GMT.
  • After that transition point, new rewards accrue and claims continue on Ethereum.
  • Sophon has announced that the NFT will be recreated on Ethereum in the same holder wallet automatically.
Withdraw any liquid SOPH claimed on the Sophon Chain before the final chain decommissioning date. No exact shutdown date has been announced yet.
See the chain migration guide for withdrawal routes and other managed positions.
