# SOPH Bridging

> Current SOPH routes during the Sophon Chain wind-down

<Warning>
  Since **June 25, 2026**, deposits into the Sophon Chain have been disabled and
  Sophon is no longer connected to LayerZero. Use
  [claim.sophon.com](https://claim.sophon.com) to withdraw SOPH from Sophon.
</Warning>

## Current architecture

SOPH is an ERC-20 token native to Ethereum. The token at the system address on the
Sophon Chain is a canonically bridged representation, not a separate token that
needs to be migrated.

As part of the chain wind-down, the SOPH NativeOFTAdapter moved from Sophon to
Ethereum. This makes Ethereum the hub for LayerZero routes to other supported chains.

## Supported flows

* **Sophon → Ethereum:** use the canonical withdrawal route through
  [claim.sophon.com](https://claim.sophon.com).
* **Ethereum → another supported chain:** use the LayerZero SOPH route available
  for the destination.
* **Sophon → another chain:** first withdraw SOPH canonically to Ethereum, then use
  LayerZero from Ethereum to the supported destination.

The following flows are no longer supported:

* Ethereum → Sophon deposits;
* LayerZero transfers to or from Sophon.

<Note>
  The previous Sophon NativeOFTAdapter address is a legacy contract and is not a
  current bridge entry point. Always start from the claim portal rather than calling
  an adapter directly.
</Note>

## Exchange and bridge integrations

For partners providing SOPH exchange or bridge services, the June 25 move of the
SOPH NativeOFTAdapter from Sophon to Ethereum is the announced operational change.
Existing non-Sophon routes otherwise remain unchanged. Do not treat the legacy
Sophon adapter as an active endpoint.

See the [Sophon Chain migration guide](/migration) for other assets, managed
positions, and the transition timeline.
