SOPH’s gas utility is being phased out with the Sophon Chain. This page describes the remaining chain-era behavior, not Sophon’s future token model.
While the legacy chain remains operational, transactions use SOPH for gas. ZKsync paymasters can sponsor or customize transaction fees so an application can pay on behalf of its users. New deposits into Sophon have been disabled since June 25, 2026. Use claim.sophon.com to review available withdrawal routes, and do not bridge new assets into Sophon. After the chain is decommissioned, SOPH will no longer be used for Sophon Chain gas. Its replacement utility is a product-funded buyback-and-burn model.
