Deflationary token

Definition

A deflationary token is designed so its supply shrinks over time, usually by burning part of the fees or tokens used, instead of growing through issuance.

A deflationary token removes units from circulation faster than it creates them. The usual mechanisms are burning a share of transaction fees, as Ethereum does with the base fee under EIP-1559, using protocol revenue to buy back and destroy tokens, or charging a transfer tax that sends part of every movement to a dead address.

The appeal is simple: if demand stays constant and supply falls, each remaining unit represents a larger share of the network. Projects highlight burn dashboards and net supply charts in marketing, and ether was labelled 'ultrasound money' for a period when burns outpaced issuance.

Deflation is not a guarantee of value. Burns depend on activity, so a quiet network may turn inflationary again, as ether did when fees dropped. Scheduled burns can be tiny relative to unlocks, and transfer-tax tokens often hide high fees or owner privileges. What matters is net supply change and real demand, not the word in the whitepaper.

Example

A network burns 2 million tokens in fees in a month while issuing 1.5 million in staking rewards, so its supply falls by 500,000 tokens and the asset is deflationary for that period.
