How to Launch an ICO on Ethereum — No Code, No Fees
Ethereum is the gold standard for token sales. Deepest liquidity, broadest wallet support, and the ecosystem every serious crypto project eventually touches.
The catch used to be complexity — writing Solidity, deploying contracts, configuring sale logic. Not anymore.
What You Need
- An Ethereum wallet (MetaMask, Rabby, or WalletConnect-compatible)
- ~$4.50 worth of ETH for gas fees
- A clear token model (see below)
- 5–10 minutes
That's the full list. One-Shotted handles the smart contracts. You handle the vision.
The Ethereum ICO Flow on One-Shotted
1. Go to one-shotted.xyz/eth
You'll see two options: Explore ICOs (browse live token sales) and Create ICO (launch your own).
2. Connect Your Wallet
Click Connect. One-Shotted supports MetaMask, Rabby, and any WalletConnect-compatible wallet. The platform uses Sign-In with Ethereum (SIWE) for secure authentication — no passwords, no accounts to create.
3. Create Your Token
Enter:
- Token name — Your project's full name
- Symbol — 3-5 letter ticker (e.g., "MYP")
- Total supply — Total tokens that will ever exist
- Decimals — Standard is 18 for ERC-20
One-Shotted deploys a standard ERC-20 token with fixed supply. The admin role is automatically revoked after minting — no one can mint more tokens later. This is a security feature, not a limitation.
4. Configure the ICO
Set your sale parameters:
- Price per token — In ETH (e.g., 0.000002 ETH)
- Description — What your project does and why it matters
- Website — Your project's URL
- Social links — Telegram, Twitter/X, Discord
- Email — Contact for investors
5. Deploy
Review the confirmation screen. Approve the transaction in your wallet. One-Shotted deploys:
- Your ERC-20 token contract (TokenMint)
- Your ICO sale contract (TokenSale)
Both contracts are verified and deployed on Ethereum mainnet.
6. Fund the ICO
After deployment, send your tokens to the ICO sale contract address. Once funded, buyers can purchase tokens by sending ETH to the contract. The sale handles conversion automatically.
What Buyers See
Your ICO appears on the Explore page where anyone can browse live token sales. Each ICO shows:
- Project name and description
- Token price and supply
- Website and social links
- Buy button with direct wallet interaction
Buyers connect their wallet, enter an amount, and purchase. Tokens are transferred instantly.
Cost Breakdown
| Item | Cost |
|---|---|
| One-Shotted platform fee | $0 |
| Token deployment gas | ~$2–3 |
| ICO contract deployment gas | ~$1.50–2 |
| Total | ~$4.50 |
Gas varies with Ethereum network congestion. Check etherscan.io/gastracker before deploying.
Why Ethereum for Your ICO?
- Highest TVL — More capital flows through Ethereum than any other chain
- Wallet ubiquity — MetaMask alone has 100M+ installs
- DEX listing path — Post-ICO, you can list on Uniswap with the same ERC-20 token
- Credibility signal — Launching on Ethereum tells investors you're serious
- Composability — Your token works with the entire EVM DeFi ecosystem from day one
Security Model
One-Shotted's Ethereum contracts include built-in protections:
- Fixed supply — Admin revocation after mint = no inflation possible
- Verified contracts — Contract bytecode is verified on-chain before the ICO is registered
- Direct wallet interaction — No custody. Funds go directly between buyer wallets and the sale contract.
Before You Launch: Checklist
- Token utility clearly defined
- Total supply and price validated (double-check decimals!)
- Project website live with transparent information
- Risk disclosure published
- Legal review completed for your jurisdiction
- ETH in wallet for gas (~$5 recommended buffer)
