.soneium domains

An onchain TLD built on one of the emerging L2 name roots in the Ethereum ecosystem. .soneium is being developed now — permanent, agent-ready, positioned at the infrastructure layer of the next web.

01 The namespace

A namespace for L2 onchain — .soneium domains.

.soneium

.soneium is an onchain TLD — minted via Freename, held in a wallet, owned permanently. No registrar controls .soneium. No renewal window closes it. The namespace exists on blockchain: verifiable, transferable, and independent of any intermediary.

Layer 2 infrastructure is where the next web is being built. A namespace rooted in that ecosystem — owned permanently, pointed anywhere, x402-compatible from day one — is positioned exactly where the development activity is concentrated.

We hold .soneium and we're building on it. The position is set inside one of the more interesting emerging L2 name roots. The build is in progress. The window is open.

Why .soneium domains matter now.

Four infrastructure forces — all in active deployment, all converging now. .soneium is positioned inside all of them.

x402 · live on testnet

The payment primitive.

x402 is live on testnet. The protocol lets AI agents pay APIs directly, onchain, without human intervention. Every agent transacting under .soneium — handling protocol interactions, developer tooling, or infrastructure access — needs a permanent identity. agent.soneium resolves and transacts natively.

AI agents · shipping 2026

Agents need identities.

Autonomous agents handling protocol operations, developer workflows, and infrastructure management are already in production. The agents handling direct onchain payments come next. subdomain.soneium is the identity that resolves across both Web3-native and ICANN-legitimate systems.

Browser resolution · incoming

The road is being built.

Browser-native onchain TLD resolution is on a public roadmap. .soneium is building history in the namespace before that resolution lands — two years of build time before mainstream adoption is infrastructure that can't be bought later.

Freename · ICANN accredited

Both worlds, one address.

Freename holds ICANN accreditation — the only Web3 domain infrastructure with that status. A .soneium subdomain works in a smart contract and in a standard compliance flow. Both worlds, one address.

02 What's inside

Built for L2 infrastructure — register your .soneium domain.

Every subdomain under .soneium is a permanent onchain address — owned by the key holder, transferable, x402-compatible. The root is .soneium. What gets built beneath it is open.

◦ permanent

No expiry. Ever.

.soneium subdomains are minted onchain. No registrar holds the key. No renewal window can close. A .soneium address is owned permanently.

◦ agent-ready

x402 native

Every .soneium subdomain is x402-compatible from day one. An agent as dev.soneium can pay, verify, and transact onchain — without intermediaries.

◦ open

Open architecture

Any .soneium subdomain can point to any wallet, protocol, or content. We hold the root. The architecture beneath it is open.
