$GSHARE is the governance token of GMC Dollar Protocol on Arbitrum, which allows holders to claim $GMC inflation when the network expands.
GMC Shares (GSHARE) are one of the ways to measure the value of the GMC Dollar Protocol and shareholder trust in its ability to maintain the GMC close to the peg. During epoch expansions the protocol mints GMC and distributes it proportionally to all GSHARE holders who have staked their tokens in the boardroom.
GSHARE holders have governance rights to propose and vote on changes that can improve the protocol and future use cases within the GMCash finance ecosystem.
