Neutron primary sources — 2026-05-02

Project status in this pass

  • No canonical standalone whitepaper or litepaper surfaced.
  • The clearest current source of truth was Neutron’s main site, the for-humans wallet page, the official SDK README, and the public docs snippets around API reference and fiat payouts.
  • The materials consistently frame Neutron as programmable Bitcoin-and-Lightning infrastructure with agent-facing tooling and broader multi-rail payout support.

Primary-source snapshots

1) Main product site

  • URL: https://neutron.me/
  • Key excerpt:
    • The site brands Neutron as “Bitcoin & Lightning Infrastructure for AI Agents.”
    • Its feature and pricing content lists Lightning send/receive, API and SDK access, a developer dashboard, and MCP access as core capabilities.
    • The same page also references multi-currency support across 30-plus fiat currencies, pushing the product beyond a narrow Lightning-only API.

2) Consumer wallet page

  • URL: https://neutron.me/for-humans
  • Key excerpt:
    • The wallet page describes Neutron as self-custodial and says Neutron never holds the user’s funds.
    • It positions the wallet as borderless and highlights BTC, USDT, and 30-plus fiat currencies.
    • This suggests Neutron is building both end-user and infrastructure/operator surfaces on top of the same payments stack.

3) Official SDK README

  • URL: https://raw.githubusercontent.com/Neutronpay/neutron-sdk/main/README.md
  • Key excerpt:
    • The README calls the SDK the official TypeScript/Node.js SDK for Neutron and says it covers Bitcoin Lightning, stablecoins, and fiat payments through a single API.
    • It documents resources for accounts, transactions, Lightning, webhooks, exchange rates, and fiat operations.
    • Example flows cover Lightning invoice creation, Lightning Address payments, onchain BTC sends, BTC-to-USDT conversion, deposit-address retrieval, webhook verification, and fiat bank payouts.
    • The key-concepts section says KYC is only required for fiat payouts, while Bitcoin, stablecoin, and swap flows do not require KYC in the documented flow.

4) Public docs snippets

  • URLs:
  • Key excerpt:
    • The overview page confirms a formal public API reference exists.
    • The fiat-out page specifically says Neutron supports sending fiat payouts to local bank accounts or mobile-money systems in selected countries.
    • Even in shallow fetch form, that payout language helps confirm the broader control-plane scope beyond Lightning-only infrastructure.

Working conclusion

Neutron is best cataloged as an AI-agent-friendly Bitcoin, Lightning, and multi-rail payments control plane. The crucial evidence in this pass was the repeated combination of explicit agent tooling, Lightning-first developer flows, stablecoin and onchain support, and fiat payout infrastructure exposed through the same API/SDK surface.
