SAFE tokens are currently not transferable as the transferability proposal was rejected by the SAFE DAO: Snapshot
This does not make it impossible to use SAFE tokens as an additional incentive for staking but payouts would have to be delayed until the transfers are actually possible.
There are also more staking providers being onboarded to Gnosis Chain, which will allow the onboarding of many new validators without sacrificing the goal of a decentralized, diverse validator set.
We are working on a proposal to optimally use SAFE tokens to accomplish this goal and we are open to hear everyone’s ideas on this as well.
