01 The namespace

The official .xtrem registry.

.xtrem

.xtrem is an onchain TLD operated by kooky — minted via Freename, open for registration. Extreme sports have a massive global following with deep cultural identity. Skate, BMX, freeride, base jump — the sports that don't follow the rules. No dedicated onchain namespace existed for this ecosystem. Until now.

A .xtrem subdomain is permanent — minted onchain, owned forever by the registrant. rider.xtrem, event.xtrem, brand.xtrem — the namespace is purpose-built for action sports culture and x402-compatible from day one.

We operate the .xtrem root. Every subdomain registered beneath it belongs permanently to whoever registers it. One-time registration, no annual fees.

The infrastructure arriving now.

Four infrastructure forces arriving in the same window. .xtrem is positioned inside all of them.

x402 · live on testnet

The payment primitive.

x402 is live on testnet. An athlete operating as rider.xtrem can receive sponsor payments, event fees, and fan support directly onchain — no platform cut, no human in the loop. The most direct infrastructure for the most direct sport.

AI agents · shipping 2026

Agents need identities.

Agents managing athlete sponsorships, event logistics, and community engagement are in production. subdomain.xtrem is the identity that carries action sports authority — permanent, verifiable, agent-ready.

Browser resolution · incoming

The road is being built.

Browser-native onchain TLD resolution is on a public roadmap. .xtrem is building history now — addresses registered today will have years of presence before mainstream resolution lands.

Freename · ICANN accredited

Both worlds, one address.

Freename holds ICANN accreditation — the only Web3 domain infrastructure with that status. A .xtrem subdomain is simultaneously onchain and ICANN-legitimate.
