Ditto is a liquid staking solution built on Aptos. Ditto lets users stake their Aptos token to earn yield and help contribute towards decentralising the network while still remaining liquid. stAPT stands for Ditto staked Aptos, and is an yield bearing index of APT (Aptos) which compounds as it earns APT from validation efforts. At initialisation, 1 stAPT will represent 1 APT staked. This ratio will increase every epoch, meaning 1 stAPT will represent more than 1 APT soon after launch. Over time the stAPT will be worth (and redeemable) for more and more APT as yield accrues.
