Self-hostable trust modules and APIs — buy once, own them forever, run them on your own infrastructure. Try any demo free, no signup.
Fair splits, fail-closed compliance, manipulation-resistant prices, tamper-evident audit, on-chain settlement. Each module is its own product. Together they're the closed loop.
In plain English: plugins you compose into your own platform — building blocks for companies turning real-world assets into digital tokens, and for software that transacts on its own.
Founder-led, early access. Every payment and security path goes through adversarial automated review and independent audit passes before it ships — and the proof is checkable: three public provenance cards and a signed wallet attestation live on the provenance page.
14 working demos online — click one and run it. What you see is the shipping code.
Every layer stands on the one below and is independently sellable. Parties your rules deny are blocked from minting; wrong prices are rejected by design; nothing happens without an audit record. That's not a feature — it's the architecture.
credentials → compliance → fair split → compliant mint → settlement → audit → governance → credit ↺
The baseline every module is held to. All running at frederickandsons.xyz.
Explainable equity for the people who actually build
Contribution-based, co-signed equity splits + a co-founder marketplace — agent-native. The fair cap table, computed and defensible.
For: Founders, partnerships, DAOs splitting ownership
Free tier — Hosted free — up to 3 partners per split, unlimited splits
Done-for-you AI that runs the busywork
33 automations for service businesses — inbox, leads, reviews, voice, billing. We scope it in a 12-minute chat, build it, ship it, and host it from $49/mo. Cancel anytime.
For: Small businesses, tradesmen, home services
Compliance-aware tokenization that fails closed — now self-hostable
BYOC multi-ledger (XRPL + TX) tokenization & settlement with fail-closed compliance, audited. Parties your rules deny are blocked from minting. Now bundles the issuer control plane, branded console and one-command deploy (formerly Issuer-in-a-Box) so you can run the whole stack self-hosted from one command. Issuance is proven end-to-end on the XRPL testnet — a real token minted on-chain from a compliance-gated blueprint (verifiable tx hash).
For: Issuers, RWA platforms, regulated tokenization
Free tier — Hosted + testnet, free (capped)
Each has a working live demo you can run right now — no signup, real responses. More modules are in development and will be listed here as they go live.
