Single-sided staking is a product label for committing one token type to earn rewards. In DeFi, it often describes a reward pool that accepts a single asset and pays the same token or another token. The name alone does not establish that the deposit participates in proof-of-stake consensus.
One deposit, different mechanisms
A simple reward contract can track each participant's balance and distribute a funded token budget over time. Other products may lend the deposited asset, support validators, or convert it into a more complex position. Withdrawal conditions, reward sources, and exposure therefore depend on the actual design.
Depositing one token is also different from holding an LP token that represents several underlying assets. Counting the tokens entered in the interface can hide what the position owns economically.
What single-sided does not guarantee
A pool that simply holds one asset does not undergo the same pair-rebalancing process that causes impermanent loss in a typical two-asset AMM. However, a one-token entry into a strategy that subsequently provides paired liquidity can still carry that exposure.
Token price declines, falling rewards, contract failures, and lockup restrictions remain possible. More reward tokens do not by themselves establish a positive return measured in money or purchasing power.
