Open Source

What Axonpay already stands on in the open, and what we plan to publish.

Already open

The protocol layer: the x402 packages on npm (@x402/core, @x402/svm, @x402/next, @x402/fetch and friends), published by the x402 Foundation under Apache-2.0. Axonpay’s facilitator uses their verification and settlement code unchanged, and every code sample in these docs uses them directly, so nothing you build depends on unpublished Axonpay code.

Planned repositories

RepoContents
examplesThe seller, agent, mandate and MCP samples from these docs, runnable end to end on devnet
leashThe mandate client wrapper as a package, with persistent budget storage
facilitatorAxonpay's policy layer and receipts ledger around the @x402/svm facilitator
mandate-programThe on-chain mandate program, after an audit

No repositories are public yet. This page will link them when they are.

Principles

  • Upstream first. Fixes that belong in x402 itself go to the x402 packages, not into an Axonpay fork.
  • Audited before deployed. On-chain programs are published with their audit report, and the deployed program’s hash can be checked against the source with a verifiable build.
  • Permissive licenses for client code, so you can embed the leash or the examples in commercial agents. The exact license per repo is TBD.
  • No hidden dependency. The docs never show code that needs an unpublished Axonpay package to run.
