Three steps. No leaps of faith.

Our method is the same for every app: first you practice risk-free, then you act with certainty.

    Use MetaMask or your Wallet Mail. Your keys never leave your wallet: you sign, you decide.

  2. 02

    Rehearse on Sepolia

    Run the same operation on the testnet with free test ETH. Same result, zero risk.

  3. 03

    Go live

    Once everything looks right, run it on Ethereum or Polygon and check it on the block explorer.

First time? Read the step-by-step guide for each app and get free test ETH.

// 03 · Security

Built like a safe.

On a blockchain, transactions can't be undone. That's why transparency isn't a feature: it's the product.

  • Verified contracts

    Every contract we generate is published and verified on Etherscan. Open, auditable code with no hidden functions.

  • You hold the key

    Transactions are signed in your wallet. We never hold your funds and will never ask for your seed phrase.

  • Industry standards

    ERC-20 tokens and ERC-721 NFTs that work with every wallet, exchange and marketplace. No surprises.

  • Total privacy

    No cookies, no analytics, no trackers. We don't know who you are, and we don't want to.

// 04 · FAQ

Straight answers.

Can't find yours? Write to us and we'll reply within 24 business hours.

Do I need to know how to code to create a token or an NFT?

No. You fill in a form with your token or NFT details and the platform generates and deploys the smart contract for you. All you need is a wallet like MetaMask to sign the transaction.

How much does it cost?

You can try everything for free on the Sepolia testnet using test ETH. On mainnet you pay the Ethereum or Polygon network fee (gas). Minting NFTs is free: you only pay that gas.

Is it safe? Do you have access to my funds?

You sign every transaction from your own wallet, and we will never ask for your seed phrase or private keys. All our contracts follow the ERC-20 / ERC-721 standards and are publicly verified on Etherscan so anyone can audit them.

What's the difference between Testnet and Mainnet?

The testnet (Sepolia) is a test network identical to the real one, but its coins have no value: ideal for practicing risk-free. Mainnet (Ethereum or Polygon) is the real network, with real costs and irreversible transactions.

Ethereum or Polygon? Which should I choose?

Ethereum offers maximum compatibility and reputation; Polygon offers much lower fees and fast confirmations. For large collections or frequent transfers, Polygon is usually the better choice.

What is Wallet Mail?

It's a crypto wallet you open with your email or phone via Magic Link, without having to safeguard a seed phrase. Perfect to get started; for significant amounts we also recommend a self-custody wallet like MetaMask.

Do you use cookies or collect data?

No. This website uses no cookies, analytics or trackers, and collects no personal or professional data.

// Before you start

Don't have a wallet yet?

For most operations we recommend MetaMask: it's free, self-custodial and works with all our apps. If you'd prefer something simpler, start with Wallet Mail using just your email.
