# Why Free Subdomains
Free subdomains have become the best-in-class web3 onboarding solution. Coinbase has issued 4 million+ of them via `cb.id`. But why? They solve two functions at once.
1️⃣ Free subdomains offer an alternative to long, impossible to memorize crypto addresses. ENS (Ethereum Name Service) subdomains are compatible across all major wallets and replace crypto addresses with human-chosen, human-memorable usernames. For example, `jess.wallet.id` is so much easier to transact with than `0xb794f5ea0ba39494ce839613fffba74279579268`
2️⃣ Free subdomains allow you to brand the addresses you give every user. If you onboard a user into web3 or you convince an existing web3 user to make your service their primary place to transact, you deserve some word of mouth from that. And ENS subdomains give you the chance to get it. Pick any web2 domain and we'll help you port it into web3. Then every subdomain is issued from your branded domain - e.g., `amelia.yourbrand.id`
