What to expect when we come on as your independent multisig signer (Secure Governance Services): → Our key on your multisig is itself a multisig. Each of our signers generates keys on a dedicated hardware wallet, with backups engraved on metal and stored across physically separate locations. → We define a clear review and approval process before we sign anything, including turnaround times and escalation paths. → We review every proposed transaction, flag concerns, and sign within agreed timeframes. Contract upgrades get reviewed first, and we only sign if the hash of the code being deployed matches the code we reviewed. → We maintain defined protocols for emergency operations, key recovery, and signer replacement, so governance keeps working when something goes wrong. When all the keys on a multisig sit with the same team, one compromise can reach the whole threshold. An independent signer removes that weak link. Learn More Here: xitter.cf/banescusebi/status/210…
