Introducing ens.diamonds 💎

🌱 ENS Ecosystem

Hey everyone :waving_hand:

Sharing a quick Sidequest that was too cool not to build.

We built ENS Diamonds – an app that lets you browse .eth names in the temporary premium, pool ETH with friends to buy them together, and co-own them through a Safe multisig.

For those who don’t know

When a .eth name expires and passes its grace period, it enters the ENS temporary premium: a 21-day Dutch auction where its begins at near $100M and falls toward zero.

The problem

There’s no good way for a group of friends, a DAO, or a community to say “let’s split the cost, buy this name together and share ownership.”

This limits premium auctions in 2 ways:

  1. It concentrates premium names among a small number of whales.
  2. It leaves money on the table for ENS – names could sell for more if groups could pool funds and buy them together.

We wanted to explore what happens when acquiring and managing .eth names becomes collaborative.

Solution

ENS Diamonds lets people browse .eth names in temporary premium, create a shared vault for a specific ENS name they want to buy, contribute ETH toward a target price, and once that target is reached move the funds into a newly deployed Safe. The Safe then registers and owns the ENS name. All contributors co-own and control the Safe.

  1. Browse premium names
  2. Start a vault for a name you want
  3. Invite friends by ENS name or wallet address
  4. Pool ETH toward the target price
  5. Finalize → a new Safe multisig is deployed
  6. Register the name together

Why this matters for ENS?

Our hypothesis is that collective buying can:

  1. Increase demand for premium ENS names.
  2. Enable names to be purchased earlier in the premium decay curve (at higher prices).
  3. Make premium name hunting more social and engaging.
  4. Unlock purchases that wouldn’t be possible for a single buyer.
  5. = Increase protocol and DAO revenue.

Some stats

While temporary premium revenue is naturally volatile, it is an important source of revenue for the ENS DAO, as shown in this report.

  • It made up 14.3% of ENS revenue in 2025 ($2.96M).
  • It hit 25.5% in Q1 2026 – up from 11.8% a year earlier.
  • As a share of core name revenue (registration + premium), it’s now nearly 29%.

But 29% undercounts the opportunity. Reported premium revenue only captures what individual buyers could pay alone. Every name that waited out the decay curve until one wallet could afford it, or expired past premium entirely, is revenue the DAO left on the table. The addressable market is the price these names would sell for if group of people could buy them, not the price a single buyer could afford. So we’re not taking a slice of the 29%, we’re growing the pie.

Security and transparency

The entire project is open source under the MIT licence and charges no protocol fee.

The contract (0x7A11F2071344ADA4D6e53D8D8F18E83C7b03e044) is immutable and has:

  • No owner or administrator.
  • No pause mechanism.
  • No upgrade path.
  • No ability for us to withdraw user funds.
  • Public and verified source code.

Feedback

We would appreciate any feedback from ENS builders, collectors, and community members.
