How to create a cryptocurrency in 8 steps

That is the whole map. The chapters below walk through each step, with the numbers, the trade-offs and the traps that most tutorials skip.

Here is the decision that saves you the most time and money.

There are three ways to create a cryptocurrency. They differ in what you own, what you control and how much work sits behind them:

Not sure which one you need? Answer three quick questions:

If you only need a token

Tokens follow a standard that wallets and exchanges already understand. On Ethereum that is the ERC-20 standard, on BNB Smart Chain the BEP-20 standard (derived from ERC-20), and on Solana a token is a mint account that stores its details. You deploy the contract, pay the network fee, and the token exists.

Most meme coins are tokens made this way. That is also why so many disappear: they are quick to make and just as quick to abandon. Our guide on how to create a meme coin covers how to make one that lasts.

When a coin is worth it

A coin with its own blockchain makes sense when the rules matter to you: your own supply and block time, your own fees, mining for your community, or a private network for a business. You also stop depending on another chain staying cheap and online.

Step 1: Decide what the coin is for

Write one sentence about who will use the coin and why. "A tip currency for our Discord", "in-game gold that players can trade" and "loyalty points for 40 shops" lead to very different choices. Purpose decides how fast blocks should be, whether people mine it, and how many coins should exist.

Tokenomics: who gets which coins

Tokenomics is the plan for how coins are created and shared out. For a coin with its own blockchain, it comes down to four questions (we go deeper in tokenomics explained):

• How many coins will ever exist? A hard cap (like Bitcoin) or a steady supply that keeps growing (like Dogecoin).
• How are new coins made? Block rewards for miners or validators, and whether they shrink over time.
• Does anyone get coins at launch? That is a premine. Keep it small and public, or skip it.
• Who runs the network? Anyone (open mining or staking) or a fixed group (proof of authority).

Write a short whitepaper

A whitepaper is a plain document that explains what your coin is for and how it works. It does not need to be long. Bitcoin's own whitepaper, "Bitcoin: A Peer-to-Peer Electronic Cash System", was published on 31 October 2008, two months before the first block was mined.

Cover the purpose, the supply rules, any premine and what it is for, how the network is run, and who is behind the project. Our crypto whitepaper guide has a section-by-section outline. If you plan to offer the coin to the public in the EU, a white paper is not optional: see chapter 7.

How does a new coin get value?

Honestly: only from people wanting to hold or use it. Code alone gives a coin no price. Value comes from a reason to use it (paying in a game, tipping, rewarding customers), a community that trusts the supply rules, and later a place to trade it. Anyone who promises you a price is guessing, or selling something.

Step 2: Pick a coin to start from

Most new coins copy an existing one and change the settings. That is called a fork. You keep years of tested code, and the wallets and tools that already work with it. Some of the best-known coins started exactly this way:

You can copy the same families today. Pick one to see it in the builder:

• Bitcoin family (Bitcoin, Litecoin, Dogecoin, Bitcoin Cash): simple, battle-tested coins that people mine. Good for community and store-of-value coins.
• Ethereum and BNB Chain: smart contracts, so your chain can run tokens, swaps and apps. Usually run with proof of authority or proof of stake.
• Cosmos: proof of stake app chains built with the Cosmos SDK, which can connect to other Cosmos chains.
• Dash and PIVX: masternode coins, where people lock coins to run special nodes and earn a share of the rewards.

Step 3: Choose how blocks are made

Consensus is the rulebook for who adds the next block. Proof of work lets anyone mine with computing power. Proof of stake picks validators who lock up coins. Proof of authority uses a fixed list of trusted validators, which suits private and business chains. We compare the first two in depth in proof of work vs proof of stake.

Step 4: Design the supply

These settings shape how your coin behaves for years, so start from tested values and change only what you have a reason to change.

Here is what halvings look like in real life. Bitcoin's reward has been cut in half four times:

Now try it yourself. Pick a preset or type your own rules:

A shorter block time feels faster but creates more orphaned blocks (valid blocks that lose a race and get dropped) on a small network. A capped supply with halvings creates scarcity. An uncapped supply with a steady reward, like Dogecoin, keeps rewards for miners predictable forever. There is no single right answer, which is why every field in our builder starts with a recommended value and a short explanation.

Step 5: Name it

Pick a name and a ticker of 2 to 6 letters. Search CoinGecko and CoinMarketCap first so you do not clash with an existing coin, and avoid names that copy a brand. The ticker is what people will see in wallets and on exchanges.

Step 6: Launch the network

A blockchain only exists while nodes run it. Start with at least two nodes in different places, so the chain stays online and new users can always find a peer to sync from. Hosting is $5 per server per month after launch, and the builder shows the exact monthly amount before you pay.

The genesis block: block zero

Every blockchain starts with a genesis block, the very first block, written straight into the code. It is what makes your chain a new chain with its own history, instead of a copy of someone else's. More in what is a genesis block.

What actually changes when you fork a coin

Forking is more than changing the name. To become its own network, a copied coin needs new values in the chain settings file, which in Bitcoin Core is chainparams.cpp. Miss one and your coin can end up talking to the original network, or rejecting its own blocks. We go through every one in how to fork Bitcoin.

Step 7: Add the services people expect

Without these, your coin exists but nobody can use it easily. Tap each part to see what it does and what it costs:

Step 8: Launch and grow

A launched coin needs people. Before you announce it, have this ready:

• Your own website that says what the coin is for, with links to the explorer and wallet downloads.
• A clear supply page: maximum supply, block reward, and the size and purpose of any premine.
• A place to talk, such as Discord or Telegram, where you answer questions yourself.
• Instructions for miners or stakers, if your coin uses them, with your pool address.

Getting listed on CoinGecko

Price sites are how most people discover a coin. CoinGecko publishes its listing rules in its methodology. In short, it looks for:

• A working website owned by the project. Sites made with a website builder are not accepted.
• A working block explorer, so anyone can check the chain.
• Trading on at least one exchange CoinGecko tracks. Coins traded only on self-serve exchanges may be turned down.
• A clearly stated circulating supply.

Our CoinGecko listing guide walks through each requirement. Meeting all of these still does not guarantee a listing. CoinMarketCap runs its own review with its own request form. Both expect a live chain, an explorer and real trading, which is why the order is: launch, build a community, list on an exchange, then apply.

How to mine your own cryptocurrency

If you chose proof of work, you and your community mine the coin from block one. Early on, few miners means each one earns a lot, which is a good way to spread coins fairly. Add a mining pool so small miners can combine their power and earn steady rewards instead of waiting for luck. See how to mine your own cryptocurrency for the full setup.

Exchange listings come after all this. Exchanges decide what they list, most charge fees, and they expect a working explorer, wallets and nodes before they look at a coin.

With RocketRPC, a coin with its own blockchain costs $149 one-time. Add-ons are priced individually, and hosting is $5 per server per month after launch, with the first month paid at checkout. Here are three real builds, priced live from the same numbers the builder uses:

How that compares with the other ways to launch a coin:

How long does it take?

• A token: minutes with a token generator, plus the time to write a page about it.
• A fork with RocketRPC: a few minutes in the builder, then about 30 minutes to deploy once payment is confirmed.
• A fork by hand: depends on your skills. You compile the code, make a genesis block, set up servers and build an explorer and wallets yourself.
• An agency build: usually weeks to months, depending on the scope.

Can you create a cryptocurrency for free?

A token costs little more than its network fee. A coin with its own blockchain always has a running cost, because its nodes need servers, around the clock. The code itself is free and open source, so the real price of doing it by hand is your time: compiling, configuring, hosting and fixing things when they break.

The attack that hits small coins

The biggest risk for a small proof of work coin is a majority attack, often called a “51%” attack: someone rents enough mining power to rewrite recent blocks and spend the same coins twice. In May 2018, an attacker took over 18 million dollars worth of Bitcoin Gold from exchanges this way, by controlling more than half of its mining power.

• Pick consensus for your size. A small community coin with little mining power is easier to attack with proof of work. Proof of stake or proof of authority can suit small networks better.
• Ask exchanges to wait for more confirmations before crediting deposits of a young coin.
• Run nodes in more than one place, and keep your node and wallet software up to date.
• Guard the keys for premine and validator wallets like cash. In our builder, premine keys can be generated in your browser and are never sent to us.

Premine: how to do it honestly

A premine is a share of the supply created for the founders at launch. Communities accept one when it is small, explained and visible on the explorer, and walk away from coins with a large hidden one. Send it to a wallet you control, never to an exchange deposit address. On Ethereum-style chains the premine is written into the genesis block; on Bitcoin-style chains it is paid out in block 1.

Is it legal to create a cryptocurrency?

In most countries, writing and running blockchain software is legal. What brings rules into play is how you sell or promote the coin. Selling coins to the public, promising profits or running an exchange can be regulated.

• European Union: the Markets in Crypto-Assets Regulation (MiCA) has applied in full since December 2024. To offer a crypto-asset to the public, the offeror must be a legal person and publish a crypto-asset white paper, unless the offer stays at or below EUR 1,000,000 over 12 months.
• United States: whether a crypto asset counts as a security depends on how it is offered and sold, and the SEC publishes guidance on this.
• Everywhere: tax rules apply to coins you create and sell.
