Lido is bringing one-transaction ETH staking to four Ethereum layer-two networks: Arbitrum, Base, Linea and Optimism. That's the news, and it matters to anyone holding ETH. A layer-two is a network built on top of Ethereum that processes transactions faster and cheaper than the main chain.
With one-transaction staking, a user stakes ETH directly on the layer-two in a single step. There is no separate bridge to Ethereum mainnet first. Lido is a liquid staking protocol, meaning users receive a token that represents their staked ETH while it earns rewards.
The announcement covered by CryptoBriefing covers Arbitrum, Base, Linea and Optimism.
One transaction on four networks
Arbitrum, Base, Linea and Optimism are all layer-twos sitting on Ethereum. Each one settles its transactions back to Ethereum mainnet eventually, but day-to-day activity happens on the layer-two itself. That is why one-transaction staking matters.
A user opens a wallet on Arbitrum, for example, and stakes ETH in one transaction instead of paying Ethereum mainnet gas to move funds across first. The same path applies on Base, Linea and Optimism.
Arbitrum's ARB token and the $10 by 2030 question
Arbitrum has its own token, ARB, and Coinpedia's price prediction piece looks at 2026, 2027 and 2030. The piece frames the open question as whether ARB will hit $10 by 2030. That number is a prediction, not a promise, and no one knows if ARB will reach it.
The staking news doesn't change ARB's supply or its price directly; it adds activity to the Arbitrum network. A date worth watching is 2030, when Coinpedia's question about the $10 level will either be answered or not.
