The Plain-English Story
Product Vision One-Pager
The one-pager that explains 0x307 to anyone in under 5 minutes. The one-sentence pitch, the problem, the solution, the numbers, and the ask — in plain English.
What Is Agentic Commerce?
Platform Overview
The complete plain-English explanation of what agentic commerce is, why the old infrastructure fails AI agents, and how 0x307's four pillars — The Tollbooth, The Vault, The Factory, The Moat — solve every problem.
The Classical Half Is Not the Cheap Half
What a Hybrid Post-Quantum Key Exchange Actually Costs, Measured
X25519 + ML-KEM-768 costs 1.9x ML-KEM alone on key generation and 2.85x on encapsulation. We measured it, and we ship the hybrid on by default anyway, for key exchange only. Why a break that is permanent deserves a hedge and one that can be repaired does not.
Green Tests, Broken Crate
Four Times in Four Days, the Thing We Tested Was Not the Thing We Shipped
Four real release defects in our own Rust crates, each invisible to the checks we were running: cargo test passing while cargo build failed, a crate you could not depend on, a component that was never built, and a crate that could not be published from Linux. The checklist we use now.
Sealed Boxes in Twenty Lines
Post-Quantum Public-Key Encryption With No Nonce for You to Get Wrong
A KEM gives you 32 bytes, not encryption. The aead-wrap feature in pqc-kem does the rest once: hybrid or ML-KEM-768, HKDF-SHA256, XChaCha20-Poly1305, no caller-supplied nonce, and one error for every failed open.
Who Answers for the Agent?
Accountable Without Being Named
An agent pays for an API call over x402. The seller knows the payment cleared, not whose agent it was. Two questions, kept apart: which owner is behind this agent (provable with signatures, no name needed), and who that owner is (answered by the bank or identity checker that already holds names).
