What Is Rebase Token in Crypto?

A rebase token automatically adjusts every holder's balance — not the price — to maintain a target. Instead of a token trading at $1.05 to signal growth, a rebase token mints new balance to every holder so the price stays near a target. Ampleforth (AMPL), OlympusDAO (OHM), and stETH are the best-known examples, each using rebasing for very different mechanics.

Also known as: rebasing token, elastic supply token

How rebase works

On a rebase event (daily for AMPL, every 8 hours for OHM historically, every epoch for stETH), the protocol multiplies every holder’s balance by a rebase factor. If the factor is 1.005, everyone’s balance grows 0.5%. A holder who did nothing now owns more tokens; the protocol’s total supply grows by the same percentage.

Use cases:

  • AMPL — the rebase factor is computed from price vs a $1 target. Above $1, balances expand (diluting holders toward the target price); below $1, balances contract. The goal is price stability for a decentralized unit of account.
  • OHM — the rebase was a reward mechanism. Staked OHM auto-compounded via daily rebases, producing triple-digit APY during the 2021 “DeFi 2.0” period. The scheme unwound as token price collapsed.
  • stETH — Lido’s staked-ETH rebases daily to reflect validator rewards. A holder’s stETH balance grows over time as validators earn ETH on their staking balance.

Integration challenges

Rebase tokens don’t play nicely with the ERC-20 ecosystem. Many DeFi protocols, AMMs, and wallets assume balances don’t change spontaneously; a rebase mid-flow can produce accounting errors.

The standard workaround is a wrapped, non-rebasing version: wstETH wraps stETH, WAMPL wraps AMPL. Wrapped versions accumulate the rebase in price rather than balance, making them compatible with Uniswap pools, Aave collateral, and Safe multisigs. Most DeFi integrations use the wrapped form.

Risks and considerations

For holders: rebase tokens look like “free tokens” but rarely represent real purchasing-power gain. In AMPL, expansion during periods above $1 often fails to drive price back to target — holders end up with more tokens at the same or lower price, net flat. OHM holders who HODL’d through the rebase boom and bust lost 99%+ from peak despite continuous token rewards.

For developers: any protocol integrating a rebase token needs to handle balance changes during the position’s life. Prefer wrapped versions for LPing, collateral, and lending integrations.

The broader lesson: the optics of “your balance grew!” can obscure the economic reality. Always compare portfolio value, not token count, over the hold period.
