What does Rebase mean in a Smart Contract written in Solidity?

edit

In a Solidity smart contract, Rebase refers to the process of adjusting the token supply to maintain the desired value for the token. This can be necessary in decentralized finance (DeFi) projects where the value of tokens is tied to external assets or indices. Rebase can increase or decrease the token supply, depending on the supply-demand dynamics of the market. The process involves manipulating the token's price by altering its supply, a mechanism designed to promote stability in volatile markets. Rebase is typically executed automatically by smart contracts that utilize decentralized oracles to obtain pricing information of external assets.
