What is Ethereum (ETH)?

Ethereum is the largest smart-contract blockchain — a shared, programmable settlement layer where applications from stablecoins to lending markets run as code that nobody can unilaterally switch off. ETH (Ether) is its native asset: it pays for computation (“gas”), secures the network through staking, and serves as the base collateral of decentralized finance.

Since its 2022 switch to proof-of-stake, Ethereum is secured by validators who lock up ETH rather than by miners burning energy. A portion of every transaction fee is burned, tying ETH’s supply dynamics directly to how much the network is used.

How Ethereum works: gas, staking and finality

Every action on Ethereum — a transfer, a swap, a contract call — consumes gas priced in ETH. Validators propose and attest to blocks roughly every twelve seconds, and finality is reached within minutes, after which transactions are irreversible without slashing a large share of all staked ETH.

Gas costs on mainnet fluctuate with demand. That variability is the main thing to know when timing an ETH transaction: the protocol is the same at 3am on Sunday as during a market frenzy, but the fee to use it is not.

ETH on mainnet and Layer 2: Base, Arbitrum and beyond

ETH no longer lives only on Ethereum mainnet. Layer 2 networks such as Base, Arbitrum and Optimism inherit Ethereum’s security while executing transactions off-chain, cutting fees to cents and confirmation times to seconds — and ETH is the gas asset on those networks too. The same coin, several places to hold and spend it.

Which layer you want depends on the job: mainnet for maximum-security settlement and deep DeFi liquidity, an L2 like Base for cheap, fast everyday activity. CryptoRoute routes ETH on supported networks — Base among them — and the widget’s chain selector always shows the live list you can actually swap on.

Moving ETH between layers has its own friction worth knowing: an official withdrawal from an optimistic rollup back to mainnet can take up to a week, which is why most users rely on third-party routes instead. A swap that simply delivers ETH — or any other asset — where you need it sidesteps that waiting game entirely.

Swapping ETH cross-chain without bridges

Moving between ETH and assets on non-EVM chains used to mean either a custodial exchange or a chain of bridge transactions, each with its own contract risk. Intent-based settlement replaces that: you declare the outcome — ETH in, BTC or SOL or a stablecoin out — and solvers on NEAR Intents compete to fill it in one atomic step.

No wrapped ETH is minted for you, nothing sits locked in a bridge, and the payout arrives natively on the destination chain at an address you chose.

Why swap ETH non-custodially on CryptoRoute

CryptoRoute holds nothing for you — there is no deposit balance, no account, and no KYC checkpoint. You send ETH from a wallet you control; the swap settles on-chain; the output lands at your address. If a swap cannot be filled, funds return to your refund address — set on every cross-chain swap you create.

People swap into ETH for concrete reasons: gas to operate on Ethereum or its L2s, collateral for DeFi, staking exposure, or simply the base asset of the largest smart-contract economy. Whatever the reason, coins that land in your own wallet are immediately usable — no withdrawal request, no queue.

Both legs of the trade are ordinary blockchain transactions you can verify in an explorer — a proof trail a custodial exchange cannot offer. Worth saying once and clearly: skipping KYC does not exempt you from the tax and reporting rules that apply in your jurisdiction.
