Burning

Burning is the permanent removal of token units from circulation, either by destroying them in a smart contract or by sending them to an address nobody can spend from. For stablecoins, units are usually burned when they are redeemed.

How burning works

Many token contracts have a burn function that deletes units from a balance and lowers the total supply. Another method is to send tokens to a burn address, an address for which no one has the private key, such as one made of zeros. The tokens still technically exist on-chain but can never move again, so they are effectively gone.

Because everything happens on the blockchain, burns can be verified by anyone with a block explorer, as long as the address or contract is genuinely unspendable.

Why burns happen

Stablecoin redemptions: when a customer returns stablecoins for dollars, the issuer burns the units so supply matches reserves. Protocol fees: since Ethereum's London upgrade in August 2021 (EIP-1559), the base fee of every transaction is burned rather than paid to block producers. When usage is high enough, more ETH can be burned than is issued.

Supply policy: some projects use revenue to buy back and burn their own tokens, or burn a share of fees, to reduce supply over time. Others burn unsold tokens after a sale. Cross-chain bridges burn tokens on one chain when they are released on another.

What a burn does and does not mean

A burn reduces supply, which by itself does not create demand. If a project burns 10% of its tokens but no one wants them, the price need not rise. Announced burns are sometimes used as marketing, and a burn of tokens that were never going to circulate, such as locked team allocations, changes little in practice.

It is also worth checking that a burn is real: tokens sent to a wallet the team controls are not burned, no matter what it is called.

Frequently asked questions

Can burned tokens be recovered?

No. If they were destroyed by the contract or sent to a provably unspendable address, they cannot be spent again.

Does burning make a token deflationary?

Only if more units are burned than issued over time. Many tokens burn some units while still issuing more.

How can I verify a burn?

Look up the transaction on a block explorer and check that the tokens went to a burn address or were removed from total supply by the contract.
