# Closed loop `kaal:entity:closed-loop` **Status.** derived This node is assembled mechanically from the 7 claims that carry the concept tag `closed-loop`. It is a roster of what the corpus says under this term. It is **not** an adjudicated definition: no single statement here has been ruled canonical, and no first-appearance call has been made. Read the claims and judge for yourself. ## Every claim under this term 7 claims across 4 works, 2018 to 2026. **2018** - [3125822-023](https://wulfkaal.github.io/claims/3125822-023) [design/argued] -- The platform's feedback loop is closed in the sense that there are no rent seeking owners: the system is entirely supported by its users and the users reap the entire profit. > Therefore the feedback loop of the platform is closed, in the sense that there are no rent-seeking6 owners: The system is entirely supported by users, and the users reap the entire profit.

SSRN: https://ssrn.com/abstract=3125822 **2025** - [5454054-022](https://wulfkaal.github.io/claims/5454054-022) [condition/argued] -- The absence of fiat par-redemption combined with limited acceptance inside merchant ecosystems makes LER rewards closed-loop utilities, which is what removes their classification as electronic money tokens or securities. > Third, the absence of fiat par-redemption and limited acceptance within merchant ecosystems positions LER voucher loyalty rewards as closed-loop utilities. This removes their classification as electronic money tokens (EMTs) or securities, which, in turn, simplifys compliance. Wulf A. Kaal, Liquid Equity Rewards (2025). SSRN: https://ssrn.com/abstract=5454054 - [5454054-024](https://wulfkaal.github.io/claims/5454054-024) [condition/argued] -- Because LER vouchers are closed-loop and non-convertible, they reduce the risk of triggering FinCEN money services business registration and Bank Secrecy Act obligations that attach to convertible or transmissible digital value. > While convertible or transmissible digital value can trigger FinCEN MSB registration and BSA obligations, LER as closed-loop, non-convertible voucher rewards reduce that risk.

SSRN: https://ssrn.com/abstract=5454054 - [5454054-025](https://wulfkaal.github.io/claims/5454054-025) [condition/argued] -- In the EU, MiCA exemptions for non-transferable utility tokens spare LER airdrops from white paper and issuer authorization requirements, but only so long as the rewards remain non-redeemable for fiat and confined to closed-loop merchant ecosystems. > In the EU, MiCA's exemptions for non-transferable utility tokens ensure that LER voucher rewards, distributed as airdrops, avoid white paper and issuer authorization requirements, as long as LER remain non-redeemable for fiat and confined to closed-loop merchant ecosystems.

SSRN: https://ssrn.com/abstract=5454054 - [5454054-030](https://wulfkaal.github.io/claims/5454054-030) [condition/argued] -- In the UK, e-money and payment services obligations attach if voucher rewards are fiat-redeemable or open-loop; otherwise LER should fall outside the Electronic Money Regulations 2011 and the Payment Services Regulations 2017 under limited-network concepts. > However, in the Uk, e-money and payments can arise if voucher rewards are fiat-redeemable or open-loop. Otherwise, LER are likely to avoid Electronic Money Regulations 2011 and Payment Services Regulations 2017 under limited-network concepts. Wulf A. Kaal, Liquid Equity Rewards (2025).
