# Burn Tokens ### What is token burning? **Token burning** is the process of permanently removing cryptocurrency tokens from circulation. This is usually done by sending tokens to an address that cannot be accessed or by calling a burn function in the token smart contract. Once tokens are burned, they can never be recovered or transferred again. The burn transaction is recorded on the blockchain, making the supply reduction transparent and verifiable. Many projects use token burning as part of their **tokenomics strategy** to manage supply and maintain long-term ecosystem incentives. Common reasons for burning tokens include: * reducing circulating supply * implementing deflationary tokenomics * correcting token distribution * removing unused tokens * supporting long-term value for holders ### Supported networks CoinFactory allows burning ERC-20 tokens on multiple **EVM-compatible networks**. Supported networks include Ethereum, Sepolia, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, Astar, Blast, Linea, Scroll, and Sonic. ### Step-by-step guide for burning ERC-20 tokens Below is a simple step-by-step tutorial for burning tokens using the CoinFactory interface. #### Step 1: Open the Burn Tokens tool Start by opening the **CoinFactory Burn Tokens** tool. {% embed url="" %} Select the network where your token contract is deployed.\ For this example, we will use **Ethereum Mainnet**. Before proceeding, make sure that: * your token is already deployed * the token contract supports the **burn() function** * your wallet holds the tokens you want to burn.
#### Step 2: Connect your wallet Click **Connect wallet** and connect a supported Web3 wallet. Supported wallets include: * MetaMask * Trust Wallet * WalletConnect wallets Make sure that: * the wallet is connected to the correct network * you have enough native currency (for example ETH) to pay the gas fee.
#### Step 3: Enter the token contract address and burn amount Next, enter the **ERC-20 token contract address**. Once the address is entered: * CoinFactory automatically loads the token information * token name and symbol are detected * the interface checks that the token supports burning. After that, specify the **amount of tokens you want to burn**. When tokens are burned: * they are permanently removed from your wallet * the total token supply decreases * the burn is recorded on the blockchain.
After reviewing the burn details, click **Burn Tokens**. Your wallet will ask you to confirm the transaction. Once confirmed: * the token smart contract executes the **burn() function** * the specified amount of tokens is destroyed * the token supply is permanently reduced. You can verify the burn transaction using a block explorer such as **Etherscan, BscScan, Polygonscan, or Arbiscan**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
