The instruments · UNCITRAL MLETR-aligned

Six instruments. One registry. One root of trust.

The registry records all six instruments on one rail. Four are electronic transferable records under UNCITRAL MLETR — whoever controls the record controls the instrument, the way holding the paper once did. A letter of credit is the issuing bank’s undertaking and an invoice is a receivable perfected by registration: both sit on the same rail, neither is a transferable record. Settles in any currency, on-chain or off — from consumer credit to global trade.

Cryptographic Anchor · Root of Trust
ISET · Signing root
Every instrument issued by the engine is signed at this root with ML-DSA-65 (NIST FIPS 204) and written to a hash-chained audit trail. Scoped sub-keys per institution; the public key is published, so any party can re-verify a record independently.

Compliance Kernel — never bypassed

Regardless of instrument type or tier, every record must pass the same MLETR-aligned invariants before it can be issued, transferred, or cleared.

Singularity — one authoritative copy Control — electronic possession (MLETR-aligned §10) Integrity — cryptographic hash hash chain Signing — Post-quantum · NIST FIPS 204 Consent — recorded and anchored Codes — every state change emits a signed status code

The instrument family.

Six instruments on one engine — four MLETR-aligned, two on their own statutory footing. Tier indicates current build state.

Why one engine + one signing root

Every instrument — promissory, letter of credit, bill of lading, warehouse receipt, invoice, draft — needs the same MLETR-aligned invariants and the same legal anchor to be enforceable. Centralising those in a single Compliance Kernel anchored to ISET's juridical RA-11057 registration standing means new instruments are template additions, not new systems. Authoring freedom scales with tier; validity never relaxes. The root of trust is the juridical account, never exposed; institutions get scoped sub-keys.
