I kept building the same thing in every project. Then I realised why.

I kept building the same thing in every project. Then I realised why.
Every Web3 project I've shipped has had the same hidden cost.

Around week three of development, I'd start building something I'd already built before. A system to make my application know who its users actually are.

Address validation per chain.
Multi-wallet merge logic.
The "link your accounts" flow.
A lightweight profile layer on top of wallet connections.

I built this in every project because it doesn't exist in the stack underneath.

Web3 has no identity OS. No layer that tells your application who a user is, what their history is, and how to reach them on whichever chain matters right now.

Endless Domains is that OS layer. One permanent on-chain identity. Resolves across 17 chains. Carries the user's full on-chain history under a human name.

The thing I kept building from scratch is now a one-line resolver call.

That's what an operating system does.
It handles what every application above it shouldn't have to rebuild.

I kept rebuilding this' story is immediately relatable to every builder.
