Historical implementation

Sophon used a custom bridge based on ZKsync’s Shared Bridge implementation and the Bridged USDC Standard. The L2 bridge held the minter role for the bridged USDC token, while withdrawals burned the Sophon representation and released the corresponding Ethereum-side asset after the batch was finalized. This information is retained for existing integration and withdrawal support only.
