Cellula.id

Cellula.id is a naming protocol on CKB for names ending in .cell, live on mainnet since 21 September 2026. Each name is one live cell under a fixed type script, and its records point to where you want to be paid. One name gives you an address wallets can pay in CKB, a Lightning address (name@cellula.id), and a web page at name.cellula.id with your picture, links and addresses.

You can also sign in to sites with a name, send signed payment requests for an exact amount, create sub-names, let a manager keep records current without being able to sell the name, and sell a name in a single transaction with no escrow. A name can be owned by a quantum-safe key. Names start at 5 USD a year. The contracts and the resolver are open source and their mainnet builds are reproducible.
