If you’re interested in safely making staking transactions, your custody solution should natively support it. @cordialsys Treasury natively supports staking for many chains, including Solana.On Sept. 8, 2025, unauthorized activity by a threat actor was detected on the Kiln platform, caused by a compromised GitHub token. After a full review with our security partners, we’ve confirmed no other customers were impacted. All Kiln services have been safely re-enabled.
