The $XRP Ledger upgrades to delegated key controls.

Institutional custodians and payment processors have long faced a security trade-off: keeping master keys offline requires manual intervention for every transaction, slowing settlement; keeping keys online exposes the full account to compromise if a signing device is breached.

The new system splits the risk.

An operator can keep the master key in cold storage while granting a hot wallet only the power to, say, approve KYC'd customers or move funds within pre-set limits.

If the hot wallet is compromised, only those specific functions are exposed.
