Token burning is the process of permanently removing cryptocurrency tokens from circulation by sending them to an inaccessible wallet address (a "burn address"). This effectively reduces the total supply of the token.
Why Projects Burn Tokens
Deflationary Mechanism: Reducing supply can increase scarcity and potentially drive up the token's value.
Fee Burning: Some blockchains (like Ethereum post-EIP-1559) burn a portion of transaction fees.
Buyback and Burn: Projects use revenue to buy tokens from the market and then burn them.
Examples
Binance Coin (BNB) conducts quarterly burns based on trading volume. Ethereum burns a base fee with every transaction. Many DeFi projects implement burn mechanisms to create tokenomic sustainability.
