How it works and why it matters

Ether is the native currency of Ethereum. It can move directly between accounts and pays execution and data-related transaction fees. Sending ETH differs from calling a token contract: a successful ETH transfer does not prove that an ERC-20 payment was made. The exact destination, chain ID and value matter.

Important technical and operational details

Every transaction specifies fee parameters, and the network charges according to computation, data, storage access, and block-space conditions. Failed contract execution can still consume ETH fees.

Validators stake ETH to participate in proof-of-stake consensus. They earn protocol rewards and can incur penalties or slashing for incorrect behavior. Individual staking, pooled staking, custodial staking, and liquid-staking tokens have different custody, withdrawal, operator, and smart-contract risks.

ETH supply changes through issuance to validators and fee burning. Net supply can be inflationary or deflationary over a period depending on network activity. Burning does not create a fixed maximum supply.

Smart contracts and decentralized finance commonly use wrapped Ether, or WETH, because ERC-20 interfaces expect token contracts. WETH is distinct from native ETH even when it is redeemable one-to-one through a contract.

Example

A customer owes 20 USDC on Ethereum but sends 0.01 ETH to the invoice address. Both may have a similar dollar value, but the payment is denominated in the wrong asset. A merchant should route it through its exception policy rather than silently declaring the USDC invoice paid.

Comparison

ETH exists on Ethereum and can also appear as wrapped or bridged representations on other networks; a matching ticker is not a guarantee that the asset, custody model or settlement path is equivalent.

Key Takeaway

ETH is Ethereum's native asset; ERC-20 payments require different transfer evidence.
