Provable, fail-closed software for the on-chain economy: fair equity, partnerships, settlement, oracles. Every product API + MCP ready

[Frederick & Sons @FrederickSonsAI]

An equal 50/50 split is a bet that both founders work exactly as hard, forever. They never do.

Fifty50 sets equity by real contribution — co-signed from day one. Equity earned, not assumed.

Tokenized Partnerships — Tokenize a partnership end to end: revenue split → contribution attestation → compliance clearance → sum-exact on-chain mint → audit, one pipeline. Deny anywhere = no mint. Adversarially audited. https://t.co/UUatAd7pgO

[Frederick & Sons @FrederickSonsAI]

On-chain disputes need a verdict that can actually execute. Evidence gated by phase, tamper-evident rulings, executable enforcement — disputes become auditable outcomes instead of off-chain arguments. https://t.co/YMEQ8NKInt

[Frederick & Sons @FrederickSonsAI]

On-chain audit trails need proof records weren't silently altered. Flight Recorder's append-only hash chain + Merkle proofs prove inclusion of one record without exposing the rest of the log. Adversarially audited. https://t.co/Jv1KmQKOPL

[Frederick & Sons @FrederickSonsAI]

Valuation disputes kill RWA deals. Meridian blends income/market/cost methods by confidence weight, applies an illiquidity haircut, and gives a full audit trail for every mark. Provenance-carded, 6/6 mutants killed. https://t.co/rs48rhlU25

Beacon — RWAs need a price feed that won't be gamed. Beacon holds an integer median across signed multi-source quotes — one source moving 10x can't shift the mark. Stale or thin? No price, not a wrong one. Adversarially audited. https://t.co/VdiWGvNqGn

Tokenized settlements clear on the ledger but disputes still slide into emails and lawyers. How do you gate the evidence by phase, rule, and enforce with every step tamper-evident? Dispute Resolution turns the fight into an auditable on-chain outcome. https://t.co/3RwXI2ycLz

[Frederick & Sons @FrederickSonsAI]

Beacon Hosted $29/mo. Manipulation-resistant price oracle.
Signed multi-source quotes, integer median, outlier rejection. Proof: a single source manipulated 10x cannot move the price.

Settlement Suite — AI agents can't do commerce on trust. The Settlement Suite gives them the whole rail: payable manifest, signed receipts, micro-payments, conditional escrow, cross-ledger finality — fail-closed, proven on XRPL testnet. https://t.co/Ghbx8nXMhG

fs-amem: durable memory for agents - SQLite-backed store/recall/consolidate/reflect, zero required deps.

README opens with a disclosure: default embedder is a deterministic hash, lexical overlap, not learned similarity. Swap in a real one in one line.

pip install fs-amem

[Frederick & Sons @FrederickSonsAI]

Most companies keep their internal infra private and sell you the product built on top of it. We did the opposite.

61 Python packages pulled from our own production stack - MIT-licensed, mostly stdlib-only. None of it is novel. All of it is real, tested, and now yours. (1/3)

[Frederick & Sons @FrederickSonsAI]

oss-infra - 18 packages: rate limiting, retry + circuit breaking, JSONL event stores, LLM cost ledgers, prompt caching, RWA cap-table/waterfall/yield math. (2/3)

The Verified Toolkit — The complete F&S verified tool catalog — finance, crypto, XRPL/RWA, business ops — every tool security-gated and behavior-tested to the same bar as the infrastructure suites. The on-ramp to the stack. https://t.co/tDAo7NJtj1

Yeah, what he said! 🤑

Watched two partners split a deal on a handshake. A year later nobody could prove who put in what. Fifty50 locks the contribution math and the co-sign into one manifest the ledger can't rewrite. https://t.co/uaNEZV9PTa

[$TX🤑Preacher @Preacher_XRP]

How do you enforce a tokenized settlement when the argument leaves the chain? Dispute Resolution opens the case, gates evidence by phase, rules and enforces — every step tamper-evident. https://t.co/3RwXI2ycLz

[Frederick & Sons @FrederickSonsAI]

Too many startups still do equity like a handshake and a hope. A year later nobody can explain why they own what they own. Fifty50 logs the real inputs—hours, cash, IP, sales—and turns them into a living split you can defend. Free to start: https://t.co/4CQyLjvtgp
