# Sophon Chain Migration

> How to claim rewards and move assets off the Sophon Chain

<Warning>
  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.
</Warning>

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](https://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.

| **Guardian NFT**                         | Claim any outstanding rewards. Sophon's announced NFT transition to Ethereum is automatic.               |
| **vSOPH**                                | Claim any unlocked SOPH. The vSOPH transition to Ethereum is automatic.                                  |
| **Staked SOPH**                          | Claim any outstanding staking rewards. The staked position transition to Ethereum is automatic.          |
| **Liquid SOPH on Sophon**                | Bridge it out. SOPH itself does not need a token migration.                                              |
| **ETH, USN, or another token on Sophon** | Use the withdrawal action at [claim.sophon.com](https://claim.sophon.com) and select an available route. |

## 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.

<Note>
  Sophon's token announcement identified the June 25 Guardian snapshot timing as
  subject to final confirmation. Follow [official Sophon channels](/links/socials)
  for any timing update.
</Note>

### 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](https://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](https://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.

  outstanding rewards and withdraw liquid assets before the final decommissioning
  date announced by Sophon.
