Four types of stablecoins differ in their price maintenance mechanisms, from reserves to algorithms.

A Zombit editorial guide published on the 9th classifies stablecoins into four reserve and stabilization models—fiat reserve backing, on-chain overcollateralized lending, derivatives hedging, and token supply adjustment—even when tokens track the same underlying currency. Tether (USDT) and USD Coin (USDC) are cited as reserve-backed examples, GHO as an overcollateralized case, and USDe as a derivatives-hedge design. The guide stresses that the dollar or euro is the price target while reserves, collateral, derivatives and supply controls are the mechanisms used to hold the peg, and that a single token can combine several approaches. The framework matters because peg stability depends on which mechanism is the primary line of defense, so the classification offers a way to compare how different stablecoins would behave under stress. What to watch next is how hybrid designs are categorized and whether tokens relying on derivatives hedges or algorithmic supply controls hold their pegs during volatility.
