# YLDS (YLDS) Quantum Readiness Report

> YLDS has a QRI score of 1/100 and is assessed at Stage 1 (Quantum Risk Assessed) with medium evidence confidence.

Evaluation date: 2026-06-07. Review status: draft. Evaluated scope: Multi-chain SEC-registered yield-bearing stablecoin token, evaluated under Token Inheritance rules for all deployed host chains as of 2026-06-07. Host-chain spend authorization, consensus, and state integrity are inherited; token-specific admin/governance keys and the off-chain transfer-agent recovery mechanism are evaluated directly..

YLDS is a multi-chain SEC-registered yield-bearing stablecoin deployed across Provenance (native), Solana, Ethereum, Sui, Avalanche, and Stellar. It inherits the classical ECC-based cryptographic security of all its host chains — none of which have production post-quantum protection as of the evaluation date. YLDS has published no cryptographic inventory, quantum threat model, PQ migration roadmap, or quantum-specific incident-response process. The QRI Score is 1/100, reflecting Stage 1 (Quantum Risk Assessed) with no meaningful production quantum protection. However, YLDS carries the PQ-Recoverable tag: as an SEC-registered face-amount certificate with Figure Equity Solutions as the registered transfer agent, legal ownership is maintained off-chain. The issuer can revoke on-chain account access and claw back tokens via Provenance Blockchain's forced-transfer feature, providing a credible — though not quantum-preventive — recovery path. With ~$557M in circulation, YLDS represents significant quantum-exposed value-at-risk that is currently unprotected on all host chains.
