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, an Ethereum OFT adapter replaced the Sophon NativeOFTAdapter. The Ethereum adapter locks ERC-20 SOPH; it requires token approval before sending. SOPH can also move directly between the other supported LayerZero chains.Supported flows
- Sophon → Ethereum: use the canonical withdrawal route through claim.sophon.com.
- Between Ethereum, Base, BNB Smart Chain, Arbitrum, Polygon and Beam: follow Bridge SOPH with LayerZero for contract addresses, endpoint IDs, approval, fee quoting and sending with the official CLI or a contract explorer.
- Sophon → another chain: first withdraw SOPH canonically to Ethereum, then use LayerZero from Ethereum to the supported destination.
- Ethereum → Sophon deposits;
- LayerZero transfers to or from Sophon.
Official contract addresses
The previous Sophon NativeOFTAdapter address is a legacy contract and is not a
current bridge entry point. For SOPH on Sophon, start from the claim portal.
For the other chains, use the current contracts in the
LayerZero guide.
