- A token is a smart contract on an existing blockchain.
- Deployment costs gas, and the transaction is irreversible.
- US securities law can apply based on how you sell.
The work is mostly planning and testing before you deploy. A deployment is public and permanent, so mistakes can be hard to fix.
What does creating a token mean?
Creating a token deploys a smart contract on an existing blockchain. The contract records balances and transfers, and the network processes them. You do not run your own blockchain.
What to prepare before you start
Choose a blockchain and token standard that fit the token's purpose. Ethereum's ERC-20 standard, introduced in 2015, defines common rules for fungible tokens. Other networks have their own standards. Then set the name, symbol, supply, decimals, and minting rules.
How do you create the token?
You can use a no-code tool for a common standard, or write the contract yourself. A copied contract can work, but it may carry hidden owner controls or bugs. The deployment transaction is public and cannot be undone.
- 1Write or select contractUse a no-code tool or write code with tests. Check copied contracts for owner controls and bugs.
- 2Test on a testnetDeploy a copy on a test network and try transfers before you spend real gas.
- 3Fund your walletThe deploying wallet needs the blockchain's native coin for gas.
- 4Review details before deployCheck name, symbol, supply, decimals, and minting rules. They are usually fixed after launch.
- 5Deploy and confirmSend the deployment transaction and pay gas. Wait for confirmation, then record the address.
What should you do after launch?
US securities law can apply based on how you sell the token, not only on its code. The SEC uses the Howey test, and the IRS treats cryptocurrency as property, so sales, swaps, and payments can create taxable events.
