A rebasing token is a liquid staking token whose holder balance grows automatically as staking rewards accrue, increasing the supply to distribute yield. It feels intuitive but breaks DeFi composability, because lending protocols and automated market makers assume a static balance per position.
Never list a rebasing LST on a lending or AMM market before confirming the market's balance-tracking handles supply changes. Rebase events can drift collateral valuations and create bad debt.
How it works
A rebasing token expands its supply at each reward accrual interval to distribute yield. Rather than appreciating per token, the protocol mints new tokens and credits them to each holder proportionally. A holder's balance grows over time while the exchange rate between one rebasing LST and the underlying asset stays fixed at 1:1.
The appeal is intuition: more tokens in your wallet feels like interest in a bank account. Holders watch their balance grow without needing to understand that a rising exchange rate conveys the same value. For simple, non-DeFi staking, the model is adequate.
Design consequence
The problem shows up in DeFi. AMMs size pool positions by token count, so depositing a rebasing token makes the pool's balance climb with every rebase even without a trade. That distorts price calculations and often traps rebased yield in the pool instead of crediting the LP. Lending protocols hit the same wall: collateral math assumes a constant balance between transactions, which automatic rebasing violates.
How we approach it
The industry response is two-pronged. Some protocols wrap rebasing tokens into exchange-rate tokens for DeFi, adding friction and gas at each entry and exit. Others moved to the exchange-rate model by default. Wrappers work, but they signal the underlying design is not natively DeFi-compatible and fragment how the token appears across dashboards and integrations.
