Uniswap rolls out 'uni.eth' subdomains using ENS infrastructure

Uniswap has rolled 'uni.eth' subdomains using the Ethereum Name Service infrastructure to let users convert complex HEXadecimal Ethereum addresses into human-readable names.

Users can claim their uni.eth subdomain through the Uniswap mobile app, which offers one subdomain free of charge. Changing names is designed to be gasless via an off-chain resolver contract.

ENS subdomains are domains created under an existing ENS domain name, typically used to enable the management of multiple ENS identities, akin to subdomains on traditional websites.

Any ENS domain owner, such as uni.eth, can create an unlimited number of subdomains as long as the ENS domain remains active. These subdomains are created and managed by the owner of the parent ENS domain.

For instance, the owner of the ENS domain "bob.eth" could create subdomains like "pay.bob.eth," "email.bob.eth," or "games.bob.eth." Each subdomain can be directed to a different website, Ethereum address or other resource.

Integration with ENS infrastructure

The integration of ENS into Uniswap's services extends previous developments in off-chain resolvers, supported by an ENS contract. In the past, projects like OptiNames on Optimism have offered subdomains.

Uniswap is the most widely used automated market maker — a decentralized exchange that facilitates trading between tokens using liquidity pools rather than relying on traditional order books where buyers and sellers directly match orders.

In the past 24 hours, the protocol has facilitated a swap volume of over $1.5 billion.
