# Lock Hyperstable uses two tokens to manage its utility and governance: [`$PEG`](/docs/usdpeg/token.md) (ERC-20), is distributed to liquidity providers through emissions and; [`$vePEG`](/docs/usdpeg/token.md)(NFT), which is used for Governance, to vote on Emissions, and receive [Incentives](/docs/protocol/incentivize.md). vePEG is protected from dilution via [Rebases](/docs/usdpeg/rebase.md). **Vote Escrow** The 've' in vePEG stands for : Vote Escrow, which is a mechanism used in decentralized governance to ensure fairness and transparency in decision-making. Any PEG holder can vote escrow their tokens and receive $vePEG in exchange. With Hyperstable, we call this Locking. **Locking**\ \ The maximum lock period is 1 year, following the linear relationship shown below: 100 PEG locked for 1 year will become 100 vePEG\ 100 PEG locked for 3 months will become 25 vePEG\ \ The longer the locking time, the higher the voting power of the underlying locked balance. Additional PEG tokens can be added to a Lock at any time. \ \ Additionally, Hyperstable Locks can be set into Auto-Max Lock, which are treated by the protocol as being locked for the maximum duration of 1 year, and their voting power does not decay. The Auto-Max Lock feature can be turned on and off for each Lock. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
