- A token runs on an existing chain; a coin has its own.
- Test the contract on a testnet before the main network.
- Securities, money transmission, and tax rules can apply.
The path you pick decides the work. A new chain means running nodes and consensus software, while a token lives inside a network that already works.
What to decide before you start
The first decision is whether to issue a token on an existing chain or launch a new one. A new chain needs its own nodes and consensus rules. An existing chain brings ready tools, and you still pick a token standard that fits what holders will do.
How to create your cryptocurrency step by step
Write the contract or generate it from tested code, and keep untested code off the main network.
- 1Pick a chain and standardChoose a blockchain whose tools fit your project and a token standard it supports, such as ERC-20 on Ethereum.
- 2Set the token rulesDecide the name, symbol, supply, and decimals, and who can mint, burn, pause, or upgrade the token.
- 3Write the contractStart from audited code. Free token creators may keep control of the contract, so check who holds the admin functions.
- 4Test on a testnetDeploy to a test network that matches the main chain, then try transfers, approvals, and admin actions.
- 5Deploy to the main networkDeploy the same code you tested and verify the contract so buyers can read it.
Legal and tax rules for issuing tokens
US law does not treat every token the same. The SEC uses the Howey test to decide whether a sale is a securities offering. The IRS treats crypto as property, so selling it can trigger tax, and some sales may count as money transmission.
After launch: records and security
Once deployed, the contract and its address are public, and many contracts cannot be changed or deleted easily. Keep records for buyers and tax filing.
Frequently asked questions
Templates and deployment tools can handle a simple token, but you still need to understand the contract's rules. A custom chain usually needs a developer.
A coin is the native asset of its own blockchain, like bitcoin on Bitcoin. A token is issued on a chain that already exists, such as ERC-20 on Ethereum.
Yes. Issuing a token on an existing chain avoids building nodes and consensus.
The contract becomes public on the chain, and you manage admin keys, records, and legal duties.
