What the Ethereum user is confirming
Ethereum validators use proof of stake to propose and attest to blocks, while execution clients process transactions and smart-contract calls against the shared account-based state.
Ethereum (ETH): How Gas Fees and Smart Contracts Work
Ethereum is a decentralized smart-contract platform, and ether (ETH) is its native asset. Ethereum uses an account-based state model where externally owned accounts and contract accounts interact through transactions executed by the network. This page focuses on how Ethereum Gas Fees and Smart Contracts Work and the checks users need before sending funds, paying fees or using the network.
Help users understand how ethereum gas fees work and make safer usage and transaction decisions for Ethereum.

Ethereum Network, ETH and Tokens
Ethereum is the network, ETH is its native asset, and token balances such as ERC-20 assets are maintained by smart-contract state.
Page subject
Ethereum
Market pair
ETH/USDT
Network family
EVM Layer 1
Network
Ethereum is a distributed state-transition network that executes transactions and smart-contract calls.
Role distinction
ETH is not an ERC-20 token. Native ETH balances belong to protocol account state, while ERC-20 balances belong to token-contract storage.
Ethereum Accounts
Ethereum tracks an account-based state containing balances, nonces, contract code and contract storage.
Account-based state
The global state maps account addresses to account data and changes as valid transactions execute.
Externally owned accounts
Externally owned accounts are controlled by private keys and can originate signed transactions.
Contract accounts
Contract accounts are controlled by deployed code and run when called by a transaction or another contract.
Nonce
An externally owned account nonce counts transactions sent and prevents the same signed transaction from being processed repeatedly.
Balance
An account balance records the amount of native ETH assigned to that account.
Code execution
Contract bytecode executes in the Ethereum Virtual Machine when a message call reaches the contract.
Contract storage
Contract accounts can maintain persistent storage that is updated by successful execution.
ETH Units
One ETH equals 1,000,000,000 gwei or 1,000,000,000,000,000,000 wei.

Conversion factor1 ETH = 10^18 wei; 1 gwei = 10^9 wei
Decimal precision18 decimal places
Ether (ETH)10^18 wei | 18 decimals
Gwei (gwei)10^9 wei | 9 decimals
Wei (wei)1 wei | 0 decimals
Wallets usually display ETH, gas prices are commonly quoted in gwei, and raw EVM values use wei.
Ethereum Gas and Fees
Ethereum charges for computation in gas; the amount of gas used and the applicable per-gas fees determine the execution cost.
Gas
Gas is the unit used to measure computational work.
Gas limit
The gas limit caps how much gas a transaction is allowed to consume.
Gas used
Gas used is the amount of metered work actually consumed by execution.
Gas price
Gas price is the per-gas price used by legacy transactions and remains a general fee reference.
Base fee
The protocol sets a base fee for each block; the base-fee portion is burned.
Priority fee
A priority fee is an optional per-gas tip paid to the block proposer.
Max fee
The maximum fee per gas caps the total per-gas amount a sender is willing to pay.
Max priority fee
The maximum priority fee per gas caps the proposer tip.
Execution cost
The final execution fee depends on gas used and the effective gas price; unused gas is not charged as consumed work.
Ethereum Transactions
An Ethereum transaction is created and signed by an externally owned account, validated and propagated by nodes, executed, recorded in a receipt, included in a block and later finalized.
- Transaction creationThe sender constructs the recipient, value, data, nonce, gas limit, fee fields and chain identifier.
- SigningThe sender signs the transaction with the private key controlling the externally owned account.
- Nonce validationNodes check that the sender nonce and other transaction fields satisfy protocol rules.
- BroadcastThe signed transaction is submitted to an Ethereum node.
- Node propagationNodes validate and relay eligible pending transactions across the peer-to-peer network.
- ExecutionThe execution layer applies the transaction against the current state and meters the work in gas.
- Receipt generationExecution produces a receipt containing status, cumulative gas information and emitted logs.
- Block inclusionA validator-selected execution payload includes the transaction in a block.
- Finality stateProof-of-stake consensus can later finalize checkpoints containing the block, subject to protocol conditions.
Ethereum Smart Contracts
Ethereum smart contracts are programs deployed as contract accounts and executed by the Ethereum Virtual Machine.
Contract accounts
A contract account has code and can be called by transactions or other contracts.
Bytecode execution
Compiled contract bytecode executes deterministically in the Ethereum Virtual Machine.
Storage
Contracts can read and update persistent storage when execution succeeds.
Contract calls
Message calls pass value and encoded input data to contract code.
Token contracts
ERC-20 token contracts implement token balances, transfers, allowances and related behavior in contract state.
Native asset and token roles
Native ETH is part of protocol account state. ERC-20 token balances are entries managed by token contracts.
Proof of Stake and Finality
Ethereum uses proof-of-stake consensus in which validators propose blocks, attest to their view of the chain and contribute to checkpoint finality.
Consensus model
Ethereum uses proof of stake to coordinate agreement on the canonical chain.
Validator model
Validators participate by proposing blocks when selected and by broadcasting attestations.
Block proposal
A selected validator proposes a beacon block containing an execution payload.
Attestations
Validators issue attestations that vote for their view of the chain and checkpoint targets.
Finality model
Checkpoint finality is reached through the protocol's proof-of-stake justification and finalization rules.
Application limitation
Applications should distinguish block inclusion from finalized checkpoints and choose confirmation policies appropriate to their risk model.
Ethereum Transaction and Fee Checks
Before the next transaction
- Choose network for the current Ethereum route.
- Fund fee asset for the current Ethereum route.
- Review action for the current Ethereum route.
- Execute for the current Ethereum route.
- Check finality for the current Ethereum route.
Where Ethereum Differs for Users
What Ethereum users should verify and why this design differs
The CoinGecko USD snapshot and Binance Spot ETH/USDT chart are separate datasets and can differ. Market reference data may be delayed or unavailable when a provider cannot return validated values.
For Ethereum, the practical sequence is Choose network, Fund fee asset, Review action, Execute, Check finality. Confirm the official destination and current network, then inspect the final balance, position, receipt or documented exit state that actually completes the task: Understand how ethereum gas fees work and make safer usage and transaction decisions for Ethereum.
Ethereum Network use FAQ
Is ETH an ERC-20 token?
No. ETH is Ethereum's protocol-native asset. ERC-20 balances are maintained by token contracts.
What determines an Ethereum transaction fee?
Execution cost depends on gas used and the effective per-gas fee under the transaction's fee settings.
Are the USD snapshot and ETH/USDT chart the same market?
No. CoinGecko provides an aggregated USD reference, while the chart represents the Binance Spot ETH/USDT market.
Known Limitations
- This page explains protocol behavior but does not replace application-specific confirmation or risk policies.
