• 100% Liquid Backing Rule: Non-bank issuers are barred from fractional-reserve operations. Permitted reserves are restricted to coins, notes, deposits in insured depository institutions, and Treasuries with maturities <= 90 days.
• Prohibition on Rehypothecation: Section 4 explicitly criminalizes the hypothecation, lending, or encumbrance of customer reserve assets.
• Bankruptcy Remoteness: Mandates the Delaware / Wyoming Statutory Trust or NY Banking Law segregation mechanism, legally establishing that token holders possess senior property claims over issuer insolvency estates.
• Statutory Par Redemption: Token holders have an affirmative federal cause of action to redeem at par within 1–2 business days.

• Asset-Referenced Tokens (ARTs) vs EMTs: EMTs reference a single official currency (e.g., EUR, USD) and must be issued by an authorized Credit Institution or Electronic Money Institution (EMI).
• Prohibition on Yield / Interest: MiCA Article 40/50 bans issuers from distributing interest to token holders to preserve bank deposit flight protections.
• The 200M EUR Non-Euro Cap: Foreign fiat stablecoins used for domestic transactions face a 200M EUR daily volume ceiling, causing major European exchanges to delist unregulated foreign stablecoins.
• Mandatory 30%/60% Bank Deposits: Significant EMTs must place at least 60% of reserve assets as direct cash deposits across multiple EU banks.

• Statistical Peg Test: Daily peg variance must not exceed 10 bps (0.10%) in ordinary trading and 20 bps in stress scenarios. More than 10 breaches of 20 bps in 12 months triggers automatic demotion.
• The Punitive 1250% Penalty: Group 2b assets receive a 1250% risk weight, requiring a dollar-for-dollar Tier 1 equity deduction (a bank holding $100M of an unapproved coin must hold $100M in cash capital).
• Redemption Risk & HQLA: Issuers must prove High-Quality Liquid Asset depth sufficient to liquidate 35%+ of circulating supply in 30 days without price dislocation.

• `pacs.008` (Credit Transfer): The backbone of FedNow and SWIFT, embedding on-chain transaction hashes, smart contract addresses, and DTI references directly into the structured remittance segment.
• ISO 24165 DTI: Assigns unique 9-character alphanumeric codes to eliminate digital asset confusion across disparate blockchains.
• ISO 17442 LEI: Standardizes institutional identity in FATF Travel Rule messaging, binding corporate entities to on-chain wallet addresses.
