Decision infrastructure for digital assets.
Every recommendation we produce ships with an immutable, replayable receipt — engine-pinned, hash-chained, and anchored to the exact provider and market facts the answer depended on. The artifact you'd want to attach to an investment-committee memo, a counterparty risk file, or a regulator's request.
The picked provider, the rejected alternatives, the ranking objective, the effective cost. Same surface a public reader sees, just persisted forever at a permanent URL.
A structured methodology block — factors, weights, scores, rejected candidates, and the evidence references that back each claim. No floating assertions: every number points back to a captured market or catalog value.
Methodology version, agent build SHA, model id, prompt version, and tool-stack hash — the five values that fix replayability. A receipt is reproducible iff each of these is still resolvable; if it isn't, the receipt itself records why.
sha256 over the canonical immutable block. prev_hash chains receipts within a session for tamper-evidence — any post-hoc edit breaks the chain visibly.
The provider/market facts the recommendation depended on, captured with per-field materiality thresholds. The drift engine evaluates these on a schedule and writes a successor receipt — never mutates the original — when a watched field moves past materiality.
Not advice. Not a fiduciary product. Not custodial. We do not execute, hold assets, or take discretion. ChainChoice is the audit trail under whoever does — internal allocator, external advisor, treasury operator, compliance reviewer.
Public receipts, hash-chained, engine-pinned, drift-anchored. Used by individual users and shared as decision evidence. Free tier; Plus/Pro upgrades for personalized state and deeper reasoning models.
Source archive (institutional snapshots of cited URLs), append-only governance log (role-based approvals, exports, escalations), and a PDF brief renderer that produces a committee-ready document directly from a receipt id.
API/infrastructure tier — the receipt schema as a service. Embedded in advisor stacks, treasury management software, and audit toolchains so the artifact follows the decision wherever it goes.
We are pre-pilot. If you allocate to digital assets and want decision evidence at institutional grade — or if you operate audit infrastructure that should consume this schema — reach out. Email institutional@chainchoice.io with a one-line description of your use case.
