Arbitrum
Layer 2 · Ethereum
Optimistic rollup that settles Ethereum transactions at lower cost.
The Ethereum Name Service maps readable names such as alice.eth to addresses, content hashes and metadata. Names are held as NFTs, so they are transferable and controlled by the holder rather than a registrar. Resolution happens through on-chain registry contracts, and integrations across wallets and applications let a single name replace long hexadecimal addresses.
