.thirdweb domains

An onchain TLD built on one of the most recognised developer tooling name roots in Web3. .thirdweb is being developed now — permanent, agent-ready, positioned at the developer infrastructure layer.

01 The namespace

A namespace for Web3 devs — .thirdweb domains.

.thirdweb

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

Developer tooling namespaces are some of the most valuable in the onchain ecosystem — the people building the infrastructure are also the people most likely to understand permanent onchain identity. A .thirdweb subdomain is owned forever by the key holder, pointed anywhere, x402-compatible from day one.

We hold .thirdweb and we're building on it. The position is set. The build is in progress. The window is open — before x402 becomes the default payment rail, before agents need verified developer identities.

Why .thirdweb domains matter now.

Four infrastructure forces converging in the same window. .thirdweb is positioned inside all of them — naturally.

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 operating under .thirdweb — handling SDK access, contract deployment, or developer tooling flows — needs a permanent identity. dev.thirdweb resolves and transacts.

AI agents · shipping 2026

Agents need identities.

Agents managing contract deployments, API integrations, and developer workflows are already in production. The agents handling onchain payments come next. subdomain.thirdweb is the identity that carries developer credibility — permanent, verifiable, agent-ready.

Browser resolution · incoming

The road is being built.

Browser-native onchain TLD resolution is on a public roadmap. .thirdweb is building history now — before the resolution layer lands, not after. That history is the position.

Freename · ICANN accredited

Both worlds, one address.

Freename holds ICANN accreditation — the only Web3 domain infrastructure with that status. A .thirdweb subdomain works in a smart contract and in a compliance flow simultaneously.

02 What's inside

Built for developer infrastructure — register your .thirdweb domain.

Every subdomain under .thirdweb is a permanent onchain address — owned outright, transferable, x402-compatible from day one. The root is .thirdweb. The architecture beneath it is open.

◦ permanent

No expiry. Ever.

.thirdweb subdomains are minted onchain. No registrar holds the key. A .thirdweb address is owned permanently — not leased, not subject to renewal.

◦ agent-ready

x402 native

Every .thirdweb subdomain is x402-compatible. An agent as sdk.thirdweb can pay, verify, and transact onchain — without intermediaries.

◦ open

Open architecture

Any .thirdweb subdomain can point to any wallet, contract, or content. We hold the root. The architecture beneath it belongs to whoever builds it.
