ISET eInstruments are the instrument layer under lenders, trade counterparties, and banks: twelve instrument classes issued as post-quantum-signed records whose control — who holds the instrument right now — is enforced by the registry and verifiable by anyone — no account, no trust in us.
Every electronic promissory note today is a PDF in someone's private database. It can be copied, its terms disputed, and once the debt is transferred or sold, no third party can cleanly prove who the legitimate holder is. Duplicate originals, forged endorsements, and resold-debt uncertainty are structural — not edge cases.
Full lifecycle is demonstrable end-to-end today: issue → endorse → accept → settle, and maker-claimed default after maturity — every transition a signed on-chain transaction. The contract governs control only; it never custodies or moves funds — settlement runs on any rail, fiat included (InstaPay · PESONet · bank). The registry also operates standalone, with no blockchain exposure; on-chain anchoring is an optional upgrade that makes exclusivity operator-independent.
Records have legal standing as electronic documents and signatures under the Electronic Commerce Act (RA 8792). What RA 8792 does not settle is full negotiable-instrument status — the electronic equivalent of indorsement and delivery. That is what the UNCITRAL MLETR codifies, and the Philippines has not yet enacted it. We therefore built the control architecture MLETR's test requires — single authoritative record, exclusive control, integrity, identifiable holder — so records are MLETR-ready ahead of recognition, not claimed compliant before it.
For secured lenders today, the Personal Property Security Act (RA 11057) is the operative hook: §19 ranks possession or control of an instrument above registration when perfecting a security interest — and exclusive on-chain control is the electronic analogue of possession.
Sandbox scope, plainly: records today are signed and independently verifiable, with no asserted legal effect. Production recognition follows issuer qualification and regulatory engagement — SEC, BSP, NPC.
| Step | Shape |
|---|---|
| 1 · Scope | One corridor, one instrument (ePN), agreed success criteria — clearance time, dispute rate, verification cost |
| 2 · Run | Live issuance and endorsement between real counterparties — registry-only with fiat settlement, or chain-anchored on testnet; white-label branding on the records your customers see |
| 3 · Evaluate | Measured results against criteria; production path (issuer agreement, server-side API keys) decided on evidence |
Design-partner stage is free. Integration is HTTPS + JSON against the registry API; no blockchain expertise required of the partner.
· The settlement contract holds one note per instance today — per-note scaling is a staged engineering step, not a research problem. · Mainnet runs issue + settle; the endorsement upgrade is staged, pending deployment. · No legal-effect claims until the compliance step completes. · The registry signs and records; it is not a lender and never touches funds.
