One of the unique features of Callisto is the ability to earn interest on held funds through a process called cold staking. In essence, with cold staking you are lending your funds to the network on a short-term basis and rewarded with Callisto, proportionate to the period of time you stake your funds and the amount of CLO in the reward pool, funded by the Callisto treasury.
