ARB 
ENA 
OP Arbitrum leads the Layer 2 network with its deep DeFi liquidity and approximately US$1.7 billion in total locked positions (TVL). Optimism gains exposure through its expanding OP Stack and hyperchain ecosystem. Ethena stands out for its adoption of USDe, demand for synthetic dollars, and potential fee sharing.
Investors often chase short-term gains without studying the logic behind the project. A better approach is to focus on projects with strong networks, practical products, and clear needs. For these reasons, the following three potential altcoins are worthy of attention in 2026. Arbitrum leads the Layer 2 network with its deep mobility and active DeFi ecosystem. Optimism provides investment opportunities through the growth of the OP Stack chain group. Ethena brings a different model through USDe and cryptocurrency native revenue. Every project has risks, but each has a unique investment logic.
Arbitrum (ARB)
Arbitrum is still one of the Layer 2 networks worthy of attention, with currently approximately US$1.7 billion locked positions. The network has deep liquidity in decentralized financial applications, which gives it a strong position outside the Ethereum main network. ARB mainly serves as a governance token for the Arbitrum DAO, with holders participating in decisions on upgrades, capital expenditures and major proposals. However, current ARB holders cannot directly receive a share of the sorter fees, which are charged by Offchain Labs. The Arbitrum DAO has discussed the possibility of directing future fees to token vaults, a change that could strengthen the long-term value base of the ARB.
Optimism (OP)
Optimism takes a broader approach through the OP Stack ecosystem. This technology provides a shared framework for building the Ethereum Layer 2 network, and OP Stack is currently used in several major projects, including Base, World Chain, Unichain and Soneium. This expanding ecosystem allows Optimism to gain exposure beyond a single blockchain. Optimism Collective also earns revenue from networks that participate in hyperchains-chains that use OP Stack contribute part of the sorter revenue. This model provides OP with a potential path to achieve value improvement through ecological growth. The key question is how to achieve the scale effect of revenue sharing, and stronger adoption may make the superchain more valuable over time.
Ethena (ENA)
Ethena provides a different investment logic through USDe synthesis of U.S. dollars. USDe uses its delta-neutral perpetual contract position to generate revenue within the agreement, with current supply of nearly US$3.9 billion, demonstrating strong demand for the product. The pledged USDe (called sUSDe) is the version that generates revenue. ENA is trading at approximately $0.11 and has a market value of approximately $926 million. ENA holders manage important agreement parameters and future decisions, and may eventually receive part of the agreement fee. However, the final fee sharing structure is still under discussion and this uncertainty carries risks, but strong growth in USDe may support ENA demand.
Arbitrum provides deep DeFi mobility and strong Layer 2 status. Optimism provides investment opportunities in an expanding ecosystem through OP Stack. Ethena combines USDe adoption with a unique revenue-oriented model. These three altcoins each have different growth logics, but investors should carefully weigh the risks.
