Looking at Arbitrum ecosystem tools, there's a notable gap worth mentioning: Arbiscan doesn't fully support ENS name resolution across all address displays the way Etherscan does on Ethereum. When you browse Arbitrum addresses on Arbiscan, you'll notice ENS names don't show up consistently in places where they appear on Etherscan for Ethereum addresses. This kind of parity in user experience between major blockchain explorers matters for cross-chain adoption. As Arbitrum continues growing as a layer-2 solution, aligning these features would improve the overall experience for users navigating between chains.
