Rebase Mechanisms

Rebase mechanisms are automated supply adjustments where the protocol programmatically changes the circulating supply of a token to align its market price with a target value. In a rebase token, the number of tokens in a user's wallet increases or decreases proportionally based on the protocol's algorithm.

This does not change the user's percentage ownership of the total supply, but it alters the nominal balance. These mechanisms are often used in algorithmic stablecoins to keep the price anchored to a fiat currency like the US dollar.

When the price is above the target, the supply expands, and when it is below, the supply contracts. This creates a highly volatile and speculative asset class that requires users to understand that their holdings will fluctuate in quantity.

Rebase protocols often rely on complex oracle systems to provide accurate price data for the adjustments. While they offer a unique approach to stability, they also carry significant risks of death spirals if the price fails to recover after a contraction.

They represent an experimental frontier in decentralized monetary policy.
