Rebase Tokens: Elastic Supply and Changing Wallet Balances
Rebase tokens automatically expand or contract their supply to move toward a target price. Because the number in your wallet can change on its own, they can be confusing at first. This guide explains the concept, structure and cautions.
What is a rebase token?
A rebase token automatically adjusts its total supply at regular intervals to approach a target price, such as $1. This is called elastic supply. Whereas an ordinary coin's supply is fixed while market price changes, a rebase token changes its issuance itself to influence price.
The adjustment applies simultaneously and proportionally to every holder's wallet. Your token count changes without any action on your part.
How does automatic supply adjustment work?
Rebases usually occur at scheduled times, such as once daily or every 8 hours. The direction is straightforward:
- Price above target: Increase supply through a positive rebase to try to lower price.
- Price below target: Reduce supply through a negative rebase to try to raise price.
The increase or decrease affects every wallet at the same rate. Your percentage share of the total therefore stays unchanged immediately after a rebase. The count changes, not your proportion.
An example
A holds 100 rebase tokens out of a total supply of 1,000, giving A a 10% share.
If price exceeds the target and supply doubles to 2,000, A's balance automatically becomes 200. The count rises, but the share remains 10%. If supply instead halves to 500, A's balance becomes 50, still a 10% share.
More tokens do not automatically make you richer, and fewer tokens do not by themselves prove a loss. Actual value is quantity × price.
Beware of the unit-price illusion
A common misunderstanding is the price illusion. The displayed price per token is designed to remain near a target and may look relatively stable. But because supply changes, both quantity and price changes must be included when valuing your holdings.
| Feature | Ordinary coin | Rebase token |
|---|---|---|
| Supply | Generally fixed | Automatically changes at intervals |
| Wallet quantity | Changes through transactions | Can change on its own |
| Holding value | Quantity × price | Quantity × price, including quantity adjustments |
Watching market capitalization alongside unit price helps avoid misunderstandings about an asset's scale.
Risks and cautions
The rebase structure is interesting, but its risks are clear:
- Value volatility: Even if price looks stable, shrinking supply can rapidly reduce your holdings' value.
- Complexity: Automatic quantity changes complicate P&L calculations and tax treatment.
- Design and operational risk: Failure to maintain the target can accelerate a decline.
- Scams and exaggerated promotion: Some promoters present a growing token count as profit. For scam prevention, remember that more units do not equal returns.
