BSVKey · Custody for industry

All industries

In design

For tokenized-fund issuers, digital-asset custodians and stablecoin issuers

Answer the trust question before your holders ask it.

Tokenized funds and stablecoins compete on trust. Holders who can check the backing any day, instead of waiting for the next report, have one less reason to leave, and a late or quietly revised report is exactly what shakes confidence.

What it costs you today

Holders and counterparties rely on periodic reports, and on the issuer's word in between. Every reporting cycle is a moment of doubt, and every late or revised report costs confidence that is expensive to win back.

What changes

Backing anyone can check

The custodian signs daily holdings, and any single position can be proven without publishing the rest.

Reports that can't be quietly changed

Each reserve report is fingerprinted and signed when it is published, and a late report is recorded as late.

Fewer disputes over official data

A signed record of exactly what an auction result or data release said, and when, for contracts that depend on it.

Do it now

No call needed: open the service, see the price, and run it on the spot. You are charged only when the result is delivered, and the signed result is yours to download and check.

Timestamp holdings and reserve reports

Anchor each report the moment it is published, so a quiet revision is detectable.

How it works

Each party signs a small record at the moment it takes responsibility. The records chain together, so a missing, edited or forged one is caught.

RecordSigned bySays
finance.holdings/1the custodianone fingerprint over all positions at an as-of time (instrument, CUSIP, amount), the count, and totals by type; any single position provable on its own
finance.reserve/1the issuer, countersigned by its accountanta fingerprint of the reserve report, its totals and the period it covers
finance.release/1the recording servicea fingerprint of a published data release, where it was fetched from, and when
finance.gap/1the attestation servicean expected attestation or report that did not arrive on time

All records use canonical JSON, a SHA-256 fingerprint and an Ed25519 signature, the same primitives proven in our space custody work.
