Special Fee Contract

The Special Fee Contract (SFC) manages a set of chain validators and their delegations on the Sonic chain. It receives internal epoch-sealing transactions created by the Sonic node to handle reward distribution. The communication between the SFC and the Sonic node is mediated by the NodeDriver and NodeDriverAuth contracts.
