What is QNTX?

QNTX is an open-source organization building the infrastructure layer where AI meets Web3. Every project is MIT / Apache-2.0 dual-licensed, written primarily in Rust, and designed to compose together.

Mission​

We build open-source AI + Web3 infrastructure.

The crypto economy needs autonomous agents that can discover each other, communicate, and transact — without human intermediaries. QNTX provides the building blocks:

  • Payments — the x402 protocol lets any HTTP endpoint accept crypto payments via a standard 402 Payment Required flow.
  • Agent communication — the A2A (Agent-to-Agent) protocol enables agents to discover capabilities and exchange tasks.
  • Identity & reputation — the ERC-8004 standard provides on-chain registries for trustless agent verification.
  • Wallets — deterministic HD wallet derivation from a single BIP-39 mnemonic, across Bitcoin, Ethereum, and Solana.

Design Principles​

  • Modular — each crate solves one problem; compose them as needed.
  • no_std-first — library crates compile without std where possible, enabling embedded and WASM targets.
  • Zero async_trait — pure RPITIT (return-position impl Trait in trait) with no trait-object overhead.
  • Strict linting — pedantic + nursery + correctness (deny) across all workspaces.
  • Rust 2024 edition — latest language ergonomics and safety guarantees.
