Ethereum for Exchange Users: ETH, ERC-20 Tokens, Accounts and Gas Explained (2026)
What is Ethereum, and what do you actually own when you hold ETH on an exchange?
Ethereum is a public blockchain where accounts hold ether (ETH) and tokens and can run smart contracts, and ETH is the coin used to pay for activity on it. When you hold ETH on an exchange you own a claim on the exchange's books, not coins in a wallet you control; the coins only sit on-chain in your own account once you withdraw them.

CoinX is GSPTeck's crypto projects hub, home of CoinDrop and Swappr. For readers who started with an exchange app, the vocabulary around Ethereum is where most confusion lives: ETH versus tokens, accounts versus wallets, and mainnet versus networks that look similar. This page covers those basics in plain terms.
What is an Ethereum account?
An Ethereum account is an entity with an ETH balance that can send messages on Ethereum, and it comes in two types. Ethereum.org says an externally-owned account (EOA) is controlled by anyone holding its private keys, while a contract account is a smart contract controlled by code.
| Externally-owned account | Contract account | |
|---|---|---|
| Controlled by | Private keys | Contract code |
| Creating it costs | Nothing | A deployment transaction |
| Can start a transaction | Yes | No, only respond to one |
| Typical example | Your wallet address | A token or exchange contract |
Your wallet app shows an EOA address, a 0x followed by 40 characters. The keys behind it are what matter: whoever holds them controls the funds, which is why our guide to the seed phrase, private key and password is worth reading before you move anything off an exchange.
What is the difference between ETH and ERC-20 tokens?
ETH is Ethereum's native coin, and ERC-20 tokens are separate assets created by smart contracts that follow a common standard. Ethereum.org describes ERC-20 as the standard for fungible tokens on Ethereum, which lets wallets and exchanges handle them the same way. Both sit at the same address, but the token balance is recorded in the token's contract, not as ETH.
- ETH pays the network fee for every transaction, including a token transfer.
- A token such as USDT or USDC is a contract-defined balance; you still need ETH to move it.
- The same name on another network, such as a token on a different chain, is a different asset record even if the symbol matches.
Moving an ERC-20 token with no ETH in the wallet is the classic stuck-funds case. Our guide to network fees and gas explains why.
How do fees work on Ethereum?
Every transaction pays gas, which Ethereum.org explains has two parts: a base fee set by the protocol and an optional priority fee, or tip, that you add so validators choose your transaction. Ethereum.org's example shows a plain ETH transfer using 21,000 units of gas, and that the base fee is burned, removed from circulation, while the tip goes to the validator.
You do not need to calculate this yourself, because wallets estimate it. The point is that the fee is paid in ETH even when you send a token, and that it changes with network demand.

What does an exchange deposit address have to do with Ethereum?
An exchange gives you a deposit address on a specific network, and the network must match the one you send on. The exchange controls the keys to that address, which is why the funds are the exchange's liability until you withdraw them to an address you control.
- Choose the network the exchange lists for the asset, not the one your wallet defaults to.
- Copy the address and compare the first and last characters after pasting.
- Send a small test amount first and wait for it to arrive.
- Check the explorer for the transaction before you send the rest.
The deposit address and network selection checklist covers each step in detail.
What are mainnet, testnets and other networks?
Mainnet is the main Ethereum blockchain where real-value transactions happen, and testnets are practice networks whose coins have no value. Ethereum.org says that when people and exchanges discuss ETH prices they mean Mainnet ETH, and that testnets give you a cheap, safe version of Ethereum to play with. It also advises against reusing mainnet accounts on testnets or the reverse, for security.
The practical lesson is that a similar-looking address can live on a different network. An address that works on Ethereum mainnet may also exist on other networks that copy its format, but the balances are separate. Before you send, confirm the network name in both the sending wallet and the receiving screen, and never send from a testnet "faucet" wallet to a mainnet address or the reverse. Free testnet coins are for developers and carry no value, which is a different thing from the rewards in an earn app such as CoinDrop.
What is staking, and does an exchange do it for you?
Staking is locking ETH to help secure the network in return for rewards, and some exchanges offer it as a product. Ethereum.org describes staking and the ways to do it on its staking pages. If an exchange stakes on your behalf, your ETH is committed under that service's terms, and the withdrawal timing and the risk of the operator are yours to read before you click.
This page does not recommend staking or quote a reward rate, because rates change and carry risk. Read the exchange's own terms, and check Ethereum.org's staking overview to see what is being offered in plain terms.
Where do CoinDrop and Swappr fit?
Neither app is an exchange. Swappr is a free Android app for simple multi-coin crypto swaps that sends from a wallet you control and pays to an address you provide; CoinDrop is a free Android app for earning crypto daily with airdrop rewards, simple tasks and referrals. Both ask for a wallet address, so the account basics above apply directly. Install them only from swappr.website or coindrop.website and their official Play listings.
FAQ
Is ETH the same as Ethereum?
Not exactly. Ethereum is the blockchain network, and ETH, or ether, is its native coin. ETH is what pays the network fee for transactions on Ethereum.
Do I need ETH to send an ERC-20 token?
Yes. Gas is paid in ETH even when you send a token, so a wallet holding only the token cannot send it. Check that the wallet has some ETH first.
Is my ETH on an exchange on the blockchain?
Not in a wallet you control. The exchange holds the coins and records your balance in its own books until you withdraw them to your own address.
What is a 0x address?
It is the common format of an Ethereum externally-owned account address: 0x followed by 40 characters. The same format is used by other networks that work like Ethereum, so check the network before sending.
