Burn
Burning permanently removes tokens from circulation by sending them to an address nobody can access, reducing total supply.
A token burn destroys coins or tokens so they can never be spent again. The usual method is to send them to a burn address, a wallet whose private key is unknown and provably unobtainable, such as an Ethereum address made of all zeros. Because blockchains are public, anyone can verify that the burned tokens are gone.
Burns are used in different ways. Ethereum burns part of every transaction fee under a 2021 upgrade called EIP-1559, which has destroyed millions of ETH and sometimes made the supply shrink during busy periods. BNB performs scheduled quarterly burns. Some projects burn tokens to correct a mistaken over-issuance or to retire unsold allocations.
A burn reduces supply, but it does not automatically increase value. If a project with 1 billion tokens burns 100 million, each remaining token represents a slightly larger share of the same project. Whether the price responds depends entirely on demand. Burns announced mainly for marketing effect deserve skepticism.
