Ethereum, Arbitrum, Base, and Optimism Explained in Simple Terms: and why tools like OneClickSender matter across all of them
Jan 15, 2026

As crypto adoption grows, one thing becomes clear very quickly. Users are no longer interacting with just one blockchain. Ethereum remains the foundation, but most daily activity now happens across multiple Layer 2 networks such as Arbitrum, Optimism, and Base.
This multi-network reality creates new challenges, especially when it comes to sending tokens efficiently.
Ethereum is the base layer
Ethereum is the core settlement layer of the ecosystem. It offers strong security, decentralization, and a robust smart contract environment. The tradeoff is cost. When network usage is high, fees increase and simple actions like sending tokens become expensive.
For this reason, Ethereum is no longer where most everyday transactions happen. Instead, it acts as the final layer where results are settled and secured.
Layer 2 networks handle execution
Arbitrum, Optimism, and Base are Layer 2 networks built on top of Ethereum. They process transactions faster and at a much lower cost, then periodically settle the results back to Ethereum.
From a user perspective, these networks feel similar to Ethereum but are far more practical for frequent transactions such as transfers, rewards, and distributions.
This shift is important because it changes how users move assets. Token transfers are no longer confined to a single chain.
The real challenge is not bridges, it is execution
While much attention is placed on bridging assets between networks, many real-world use cases happen entirely within a single chain. Airdrops, payrolls, community rewards, and treasury movements often require sending tokens to dozens or thousands of addresses on Ethereum or on a specific Layer 2.
Manually sending tokens one by one across any of these networks is slow, expensive, and error-prone. This problem exists regardless of whether the chain is Ethereum, Arbitrum, Optimism, or Base.
Why OneClickSender fits the multi-chain reality
OneClickSender is designed to simplify token transfers within a network. Instead of managing repetitive transactions manually, users can send tokens to multiple addresses in a single execution, whether they are operating on Ethereum or supported Layer 2 chains.
As activity continues to fragment across different Ethereum-compatible networks, tools that abstract away repetitive operational work become essential.
The value is not in replacing wallets or blockchains, but in making routine actions efficient and predictable.
One ecosystem, many layers
Ethereum provides security. Layer 2 networks provide speed and affordability. Tools like OneClickSender provide usability.
Together, they form a practical stack where users can operate across networks without unnecessary friction. As the ecosystem grows, the winners will not be single chains, but workflows that reduce complexity for everyday users and teams.
Understanding this layered structure explains why simple tools often become the most important infrastructure.
