The Sophon Chain is being wound down. Since June 25, 2026, new deposits into Sophon have been disabled. Withdrawals remain available while the chain is operational, but you should move any liquid assets off Sophon before the final decommissioning date.
Sophon is moving from operating a general-purpose chain to building applications on Base. The chain is expected to remain operational until late 2026, but there is no fixed shutdown date yet. The final date will be announced in advance. Use claim.sophon.com for the entire transition: claim staking or Guardian rewards and find a route to withdraw assets from Sophon.

​
What you need to do

  1. Claim outstanding rewards. Check the claim portal for unlocked staking and Guardian rewards.
  2. Withdraw liquid assets. Bridge SOPH, ETH, USN, and any other tokens you hold on Sophon to another chain.
  3. Do not manually migrate managed positions. Guardian NFTs, vSOPH, and staked SOPH are being moved to Ethereum for their holders.

Key dates

​
June 25, 2026

  • New deposits through the canonical Ethereum-to-Sophon bridge were disabled.
  • Sophon was removed from the LayerZero network. LayerZero can no longer be used to bridge SOPH to or from the Sophon Chain.
  • Canonical withdrawals from Sophon to Ethereum remained available.
  • Sophon announced an automatic Guardian NFT transition: transfers would be locked on Sophon and the same number of NFTs would be recreated in the same holder wallet on Ethereum. The exact snapshot timing was still subject to confirmation.
Sophon’s token announcement identified the June 25 Guardian snapshot timing as subject to final confirmation. Follow official Sophon channels for any timing update.

​
September 29, 2026 at 00:00 GMT

This is the final vesting unlock and node reward distribution on the Sophon Chain. After this point, vesting, reward accrual, and claims continue on Ethereum without requiring a user migration transaction.

​
Late 2026

The chain is expected to remain operational through roughly the end of 2026 so holders have time to withdraw. This is an estimate, not a hard deadline. Withdraw before the final date announced by Sophon.

​
Guardian NFTs and node rewards

You do not need to move your Guardian NFT manually. Sophon has announced that it will recreate the same number of Guardian NFTs on Ethereum in the wallet that held them on Sophon. The Guardian reward programme continues on its original schedule: holders receive a pro-rata share of 20% of the original 10 billion SOPH supply over three years. Rewards remain on Sophon through September 29, 2026 at 00:00 GMT, then continue on Ethereum. The Sophon light-node software has been retired. Running software, maintaining uptime, and delegating a Guardian NFT are no longer requirements for Guardian holders to continue receiving rewards.

​
SOPH, vSOPH, and staked SOPH

​
Liquid SOPH

SOPH is native to Ethereum. The token on Sophon is a bridged representation, so there is no replacement token or token swap:
  1. Withdraw SOPH from Sophon to Ethereum through the canonical route at claim.sophon.com.
  2. If desired, bridge SOPH from Ethereum to another supported chain through LayerZero.
Since June 25, the SOPH NativeOFTAdapter is based on Ethereum rather than Sophon. Expect the claim portal to show the currently available routes.

​
vSOPH and staked SOPH

The vSOPH and staked SOPH transitions to Ethereum are automatic. Check the claim portal for unlocked SOPH from vSOPH and for outstanding staking rewards. Those current claims run on Sophon before the settlement transition, while SOPH principal that is unstaked now is claimable on Ethereum. Staking will be discontinued when the Sophon Chain is decommissioned. No new staking action is required for the migration.

​
Other assets on Sophon

To withdraw ETH, USN, or another token:
  1. Go to claim.sophon.com and connect the wallet that holds the assets.
  2. Select Withdraw from Sophon for the relevant balance.
  3. Review the routes supplied through Jumper and choose the route that fits your destination and asset.
  4. Confirm the transaction and wait for the selected bridge route to complete.
The portal may offer a direct route to another chain or a route through Ethereum, depending on the asset and available liquidity.

Frequently asked questions

There is no hard shutdown date yet, but new deposits are already disabled. Claim outstanding rewards and withdraw liquid assets before the final decommissioning date announced by Sophon.
No. SOPH is already native to Ethereum. If you hold its bridged representation on Sophon, withdraw it canonically to Ethereum. From Ethereum, you can use LayerZero to reach another supported destination.
No. These positions are transitioned to Ethereum automatically. You should still check claim.sophon.com for rewards that are available to claim.
No exact date has been announced. The chain is expected to remain available until late 2026, and Sophon has said the final date will be communicated in advance.
