# Works everywhere. Installs everything. You're welcome.

The agentic explosion is here.

The world is moving toward billions of AI agents transacting at machine speed, booking services, paying for compute, settling microtransactions in real time.
That future needs a payment layer built for agents, not humans.
Fast is that layer.

WHAT WE'RE BUILDING

Fast is the first payment system built for the agentic economy with three components

FastSet

FastSet

THE SETTLEMENT LAYER

A global network where millions of transactions per second are validated and finalized in parallel. Sub-100ms finality. Infinitely scalable. Verified with mathematical proofs, not trusted intermediaries.

AllSet

AllSet

THE UNIFICATION LAYER

Connects every major network into a single, unified liquidity layer. Agents and users deposit assets on any chain and access them instantly. One balance that works everywhere, plus the ability to call any smart contract on any connected network without bridges.

K Framework

K Framework

THE SEMANTICS LAYER

Provides a rigorous mathematical verification process to ensure that each trace is accurate. It is designed to be language-agnostic, meaning it can seamlessly operate with any agent runtime, regardless of the programming language used.
