Participating in Ethereum-based presales and IDOs requires ETH in a non-custodial wallet (MetaMask) — not on an exchange. The process has three steps: buy ETH on a centralised exchange, withdraw to your MetaMask wallet, and verify receipt before the presale opens. Here is the exact process.
Step 1: Buy ETH on a Centralised Exchange
Options in order of simplicity:
- Coinbase (US/EU/UK/AU): Simplest for beginners. Bank transfer or debit card. Buy ETH directly.
- Binance (global except US): Lowest fees. Multiple payment methods. Buy ETH with any fiat or stablecoin.
- Kraken: Strong regulatory compliance. Bank transfer for lower fees.
- MoonPay / Ramp Network: Debit card purchase with no CEX account required. Higher fees but instant.
Step 2: Withdraw ETH to MetaMask
- Open MetaMask and copy your Ethereum Mainnet address (starts with 0x)
- In your CEX, go to Withdraw → ETH → Crypto Withdrawal
- Select network: ERC-20 / Ethereum Mainnet (not BSC, not Arbitrum — you want mainnet ETH)
- Paste your MetaMask address — double-check the first 4 and last 4 characters
- Enter amount (keep a small amount on CEX in case you need to buy more)
- Confirm withdrawal — typically arrives in 10-30 minutes
How Much ETH Do You Need?
- Presale contribution amount: however much you plan to invest (e.g., $500 worth of ETH)
- Gas reserve: $20-50 extra ETH for transaction fees — Ethereum mainnet gas costs $2-50 per transaction depending on network congestion
- Buffer: Buy 10-15% more than you need — ETH price fluctuations can affect exact USD equivalent at time of presale
Checking Receipt in MetaMask
After withdrawal: open MetaMask → ensure you're on "Ethereum Mainnet" → check your ETH balance. If not visible within 30 minutes: check Etherscan by searching your wallet address — you'll see the incoming transaction even before MetaMask updates. If transaction is confirmed on Etherscan but MetaMask doesn't show: try switching networks and back.

Glossary
- ERC-20 Network
- The Ethereum Mainnet withdrawal option on exchanges — selecting this ensures ETH arrives on Ethereum blockchain, compatible with MetaMask and all Ethereum presales.
- Non-Custodial Wallet
- A wallet where you hold the private keys — MetaMask is non-custodial, meaning no company can freeze or access your funds without your seed phrase.
- Gas Reserve
- Extra ETH kept in your wallet beyond the presale contribution amount — needed to pay Ethereum transaction fees for the presale interaction itself.
