# SmartDelta — Lime Fintech (full reference) > Custody-native payoff-engineering software. Structured payoff mechanics, > engineered inside your own custody. Built for buy-side allocators who want > full economics without the issuing bank wrapper. This document is a structured, machine-readable summary of the SmartDelta product page at https://limex.com/smartdelta for answer engines and assistants. ## What it is SmartDelta is not a structured note, not an issuer, and not a bank wrapper. It is enterprise software infrastructure for enforcing customized, barrier-driven European payoff profiles across the liquid equities, ETFs, and cash you already hold — directly inside your custody accounts. You design the profile. You hold the underlying. You capture the full economics. ## The problem with traditional notes 1. **Unsecured debt imperative** — A traditional structured note is unsecured corporate debt of the issuing bank, not a direct allocation to the underlying. Downside mitigation comes with counterparty limits, balance-sheet concentration, and credit downgrade risk. 2. **Structural cost drag** — Embedded manufacturing markups, distribution fees, and wide secondary-market spreads create continuous performance drain. Issuers often cap upside to fund these legacy wrappers. ## Why now Rising issuer concentration and fee layers are accelerating a shift away from unsecured bank notes. SmartDelta provides infrastructure to enforce your own capital-preservation rules in-house — using programmable barriers that systematically transition exposures into cash within existing custody accounts. Risk management detached from bank solvency. ## Platform attributes - Built for buy-side allocators - Executes inside your custody perimeter - 8-decimal, audit-grade traceability - Simulated across 100,000 market paths - Live programmatic asset allocation ## How it works 1. **Model** — Model the profile before you commit capital. 2. **Execute** — Execute inside your own custody perimeter. 3. **Track** — Track synthetic exposure in real time. 4. **Conclude** — Systematic cash allocation concludes at maturity based on the final European barrier evaluation. No position settles without a human-in-the-loop verified release. ## Illustrative proof targets (Validate against verified internal data before publishing.) - Recovered manufacturing cost vs. traditional note wrappers - Bounded tracking error vs. modeled payoff - Governed exits — human-verified release before final settlement ## Who it's for - **Institutional allocators** — CIOs and portfolio teams running liquid equity/ETF books who want payoff engineering without issuer dependency. - **Family offices & fiduciaries** — Principals and operations leads who need custody-native control, traceability, and governed exits. ## Request a private walkthrough A 30-minute private walkthrough, evaluated against your active allocations, with zero commitment.
