faq:
  - q: "When does the GENIUS Act take effect?"
    a: "January 18, 2027. Section 20 sets the effective date at the earlier of 18 months after enactment (the Act was signed July 18, 2025) or 120 days after federal regulators issue final implementing rules. A final rule would have had to land by September 20, 2026 to pull the date forward, and none did, so the 18-month date applies."
  - q: "What happens on July 18, 2028 under the GENIUS Act?"
    a: "From that date, section 3(b)(1) makes it unlawful for a digital asset service provider to offer or sell a payment stablecoin to a person in the United States unless a permitted issuer issued it, or a foreign issuer qualifies under section 18. It is a distribution rule: exchanges, custodians, and payment providers that sell or deliver stablecoins to US persons carry it."
  - q: "When did MiCA start applying to stablecoins?"
    a: "June 30, 2024. Article 149 of Regulation (EU) 2023/1114 applied Titles III and IV, the rules for asset-referenced tokens and e-money tokens, from that date. The rest of MiCA, including the crypto-asset service provider regime, applied from December 30, 2024. The regulation itself entered into force on June 29, 2023."
  - q: "When does the MiCA transitional period for crypto-asset service providers end?"
    a: "July 1, 2026 at the latest. Article 143(3) lets providers that operated under national law before December 30, 2024 continue until that date or until they are authorized or refused, whichever comes first. Member States could shorten or skip the period, so the real end date varied by country. Since July 2026, serving EU clients needs MiCA authorization."
  - q: "Is Treasury's August 2026 GENIUS Act rule final?"
    a: "No. Treasury published a proposed rule on August 18, 2026 covering section 3, the prohibitions and limits on issuing, offering, and selling payment stablecoins in the US. Comments close October 19, 2026. A proposal can change before it becomes final, so build your plan on the statute and treat the proposal as the likely direction."
  - q: "Does a company that only uses stablecoins for payments need to do anything before 2027?"
    a: "Yes, mostly through its providers. Map which stablecoins you hold and move, ask each provider which role it plays under the GENIUS Act, and confirm their plan for foreign-issued tokens, which face an earlier US test than domestic ones. You probably won't need a license to hold stablecoins, but your counterparties might change what they offer."

The GENIUS Act was signed on July 18, 2025, takes effect on January 18, 2027, and bars service providers from selling non-permitted payment stablecoins to US persons from July 18, 2028. MiCA already applies in the EU: stablecoin rules since June 30, 2024, provider rules since December 30, 2024, and the last transitional period ended July 1, 2026.

Two laws, two very different clocks. The EU's is almost done. The US one is just starting to tick, and the date that will change the most for payment companies is the one furthest away.

**Key takeaways**

- The GENIUS Act's effective date is fixed now: January 18, 2027. The 120-day path closed when no final rule appeared by September 20, 2026.
- Treasury's August 18, 2026 rule on issuing, offering, and selling payment stablecoins is a proposal. Comments close October 19, 2026.
- The deadline that bites distribution is July 18, 2028. After it, service providers can't sell non-permitted payment stablecoins to US persons.
- MiCA is fully in force. Its last big transitional date for service providers passed on July 1, 2026.
- Most payment teams are not issuers. Your exposure runs through which tokens you use and which providers you use to move them.

## What are the key GENIUS Act dates?

The GENIUS Act has one enactment date, one effective date, and a string of deadlines measured from each. The table lists the ones that touch payment flows, with the section of the [enrolled text on congress.gov](https://www.congress.gov/119/bills/s1582/BILLS-119s1582enr.htm) that sets each.

| Date | What happens | Where it comes from | Status as of September 28, 2026 |
| --- | --- | --- | --- |
| July 18, 2025 | Act signed into law | Enactment | Done |
| July 18, 2026 | Deadline for federal and state regulators to issue implementing rules | Section 13(a), 1 year after enactment | Passed with rules still in proposal |
| August 18, 2026 | Treasury proposes rules on issuance, offer, and sale | Federal Register 2026-16796 | Proposed, comments close October 19, 2026 |
| January 18, 2027 | Act takes effect | Section 20, 18 months after enactment | Fixed |
| January 18, 2027 | Foreign-issued stablecoins need an issuer that can and will comply with lawful US orders | Section 3(b)(2), from the effective date | Upcoming |
| January 18, 2028 | States submit initial certifications that their regimes are substantially similar | Section 4(c)(4), 1 year after the effective date | Upcoming |
| July 18, 2028 | Service providers may only offer or sell payment stablecoins from permitted issuers (or qualifying foreign issuers) to US persons | Section 3(b)(1), 3 years after enactment | Upcoming |
| July 18, 2028 | FinCEN guidance and rulemaking on new methods to detect illicit activity | Section 9(d), 3 years after enactment | Upcoming |

The Treasury proposal is the [Federal Register notice of August 18, 2026](https://www.federalregister.gov/documents/2026/08/18/2026-16796/genius-act-regulations-on-payment-stablecoin-issuance-offer-and-sale). It covers section 3 only. Other agencies have their own proposals for the issuers they supervise; the [GENIUS Act guide for businesses](/resources/more/genius-act-for-businesses) lists them.

## How is the GENIUS Act effective date calculated?

Section 20 says the Act takes effect on the earlier of two dates: 18 months after enactment, or 120 days after the primary federal regulators issue final implementing rules. Eighteen months after July 18, 2025 is January 18, 2027.

The arithmetic decides it:

1. Count back 120 days from January 18, 2027. That lands on September 20, 2026.
2. A final rule issued on or before that day would have moved the effective date earlier.
3. No final implementing rule was issued by then. A final rule issued today would point to a date after January 18, 2027, and the earlier date wins.
4. So January 18, 2027 is the effective date, and late rules can't pull it forward.

Why this matters: every "X after the effective date" deadline is now a real calendar date. The state certification deadline is January 18, 2028, for example.

The other clock runs from enactment, not from the effective date. Section 3(b)(1) starts "3 years after the date of enactment," so July 18, 2028 is fixed no matter how long rulemaking takes.

## What are the key MiCA dates?

MiCA, Regulation (EU) 2023/1114, applies in stages set by Article 149, with transition rules in Article 143. All dates come from the [regulation's text on EUR-Lex](https://eur-lex.europa.eu/eli/reg/2023/1114/oj/eng).

| Date | What happens | Article |
| --- | --- | --- |
| June 29, 2023 | Regulation enters into force; a short list of provisions (mostly mandates for technical standards) applies | Article 149(1) and (4) |
| June 30, 2024 | Titles III and IV apply: asset-referenced tokens (ARTs) and e-money tokens (EMTs) | Article 149(3) |
| July 30, 2024 | Last day for existing non-bank ART issuers to apply for authorization and keep issuing while they wait | Article 143(4) |
| December 30, 2024 | The rest of MiCA applies, including the crypto-asset service provider (CASP) regime | Article 149(2) |
| July 1, 2026 | Latest end of the CASP transitional period (shorter where a Member State chose) | Article 143(3) |
| December 31, 2027 | Trading platforms must have compliant white papers for older crypto-assets admitted before December 30, 2024 | Article 143(2)(b) |

Dollar stablecoins like USDC are EMTs under MiCA. The practical effect for payment companies came through distribution: EU platforms dropped non-compliant EMTs for EU clients. The [MiCA explainer](/resources/more/mica-stablecoin-rules-explained) covers what EMT issuers must do.

## How do the GENIUS Act and MiCA timelines compare?

MiCA regulated issuers and service providers on almost the same schedule. The GENIUS Act gives issuers until January 2027 and distributors until July 2028. Same idea, different sequencing.

| Milestone | GENIUS Act (US) | MiCA (EU) |
| --- | --- | --- |
| Law adopted | July 18, 2025 | May 31, 2023 (in force June 29, 2023) |
| Stablecoin issuer rules apply | January 18, 2027 | June 30, 2024 |
| Service provider rules apply | Foreign-issuer test from January 18, 2027; permitted-issuer-only sales from July 18, 2028 | December 30, 2024, with transition to July 1, 2026 at the latest |
| Who writes detailed rules | Treasury, the OCC, the Federal Reserve, the FDIC, NCUA, and state regulators | The European Commission, EBA, and ESMA through technical standards |
| Status in September 2026 | Rules proposed, not final | Fully applied |

## Which role does your company play under each law?

Each deadline binds a specific role. Before you put a date in your plan, know whether you are an issuer, a service provider, or a user.

- **Issuer.** Under the GENIUS Act, only a permitted payment stablecoin issuer may issue a payment stablecoin in the US (section 3(a)). Under MiCA, EMT issuers must be credit institutions or e-money institutions. Few payment teams are here.
- **Digital asset service provider (US) or CASP (EU).** The GENIUS Act defines a digital asset service provider in section 2(7) as a person that, for compensation or profit, exchanges digital assets for money or other digital assets, transfers them to a third party, acts as a custodian, or takes part in issuance services. It excludes protocols, validators, and self-custodial software interfaces. A business that converts stablecoins to fiat for customers may fit that definition. Confirm with counsel.
- **User.** A company that holds stablecoins and pays through providers. The July 2028 rule doesn't bind you directly, but it binds the providers you depend on, so the tokens they offer may change.

If you're not sure which applies, read [what a VASP is](/resources/more/what-is-a-vasp). The EU's CASP and the US definition overlap with that concept.

## What should payment teams do before each deadline?

Work backward from the dates that bind your providers. Here is a calendar you can copy.

1. **Before October 19, 2026.** Read the Treasury proposal. If your business depends on a foreign-issued stablecoin, the comment period is the time to say so.
2. **By the end of 2026.** Inventory every stablecoin you hold, accept, or pay out, with the issuer and the network for each. [USDC vs USDT for payments](/resources/more/usdc-vs-usdt-for-payments) explains the main differences.
3. **By the end of 2026.** Ask each provider in writing which GENIUS Act role it plays and how it will handle section 3(b)(2) on January 18, 2027.
4. **January 18, 2027.** The Act is in effect. Check that each foreign-issued token you use is still offered to you by your US providers.
5. **During 2027.** Track final rules from Treasury and the banking agencies. Update your compliance policy when they land, not before.
6. **By early 2028.** Decide your plan for any token whose issuer won't be permitted or qualified by July 18, 2028. Test a second token on your main corridors.
7. **July 18, 2028.** Non-permitted stablecoins can no longer be sold to US persons by service providers. Your flows should already run on tokens that pass.
8. **For EU flows, now.** Confirm every EU provider holds a MiCA authorization, since transitional rights ended by July 1, 2026 at the latest.

## What is still unsettled?

Plenty. Plan around the statute, and expect the details to move.

- **Treasury's rule is a proposal.** The final text may change how platforms can rely on a foreign issuer's representations.
- **Which foreign regimes qualify.** Section 18 depends on Treasury finding a foreign regime comparable. No such finding existed as of this writing.
- **State regimes.** States must certify substantial similarity by January 18, 2028. Until then, which state-issued tokens qualify is open.
- **Edges of the service provider definition.** Payment APIs, wallet software, and orchestration layers sit close to the exclusions. Expect guidance or enforcement to draw those lines.
- **MiCA reviews.** The EU can amend MiCA, and technical standards keep arriving. Fully applied doesn't mean frozen.

## How does BlindPay fit?

BlindPay doesn't issue stablecoins. It moves USDC and USDT between customer wallets and local bank rails, so the GENIUS Act and MiCA reach BlindPay customers mainly through which tokens they choose for each flow.

That choice is a field, not a migration. Every payin and payout quote takes a `network` and `token` pair, and [supported chains](/docs/kb/supported-chains) lists every combination: USDC on Ethereum, Polygon, Base, Arbitrum, Tempo, Arc, Stellar, and Solana, and USDT on Ethereum, Polygon, Tempo, Solana, and Tron. If a token's status changes in 2027 or 2028, a team can move a corridor to the other token by changing the quote request. Payouts settle over Pix, SPEI, ACH, RTP, SEPA, and SWIFT (POBO/COBO), with UETR tracking and MT103 confirmations on wires.

Put the eight dates above in your compliance calendar today, then run a test payout in each token on your main corridor so a switch is already proven when you need it.
