Burn Addresses in Crypto: What "Burned" Really Means and How to Verify It

"50% of supply burned" appears on countless token pages. Burning means making tokens permanently unspendable. There are two different ways to do it, and they show up differently in the data.

Method 1: sending tokens to a burn address

A burn address is an address for which nobody holds, or could realistically ever find, the private key. Tokens sent there can never be moved again. On Ethereum-style chains two are used by convention:

• 0x0000000000000000000000000000000000000000, the zero or null address.
• 0x000000000000000000000000000000000000dEaD, the "dead" address.

With this method the tokens still exist. Total supply is unchanged, and the burn address appears in the holder list, often as the largest holder of all.

Method 2: a burn function

Many contracts include a burn function that destroys tokens and reduces total supply. Nothing is sent anywhere; the number simply goes down. This is the cleaner method, and it is how stablecoins retire tokens on redemption.

Why the difference matters

With method 1, every percentage calculated against total supply still includes the dead tokens. A wallet holding 10% of total supply holds 20% of the supply that can actually move, if half was sent to a burn address. Data sites differ on whether they subtract burned tokens from circulating supply, which is one reason the same token can show different market caps in different places.

How burns distort "top holders"

Look at the raw holder list of a heavily burned token and the first line may read "one address holds 60%". That is the burn address, and it is the opposite of a risk: that supply can never be sold.

This is the simplest case of a wider problem with raw top-10 figures, and the reason FraudCoins classifies holders before counting. Burn addresses are identified by address and set aside, and the coin page shows the wallet, its share and the reason. Our corrections list ranks the tokens where this kind of exclusion changes the headline figure most; at the top are tokens where a single burn address holds nearly all the supply.

How to verify a burn

1. Open the token on a block explorer and go to the holders tab.
2. Find the address claimed as the burn. Confirm it is exactly one of the standard addresses, character for character. A look-alike address that someone controls is not a burn.
3. Check the share it holds against the project's claim.
4. Open the transfer that sent the tokens there to confirm when it happened and from which wallet.
5. For a burn-function burn, compare total supply now with total supply at launch, and look for the burn events in the contract's history.

What a burn does and does not tell you

A burn permanently reduces what can be sold, and it is easy to verify. It tells you nothing about who holds the rest. A token can burn half its supply and still have ten wallets holding most of the other half. It also tells you nothing about whether more can be created: check whether the contract is mintable.

Burned liquidity is a related but separate idea, where the tokens representing a trading pool are burned so the pool can never be withdrawn. That is covered in liquidity locked.
