US, EU, UK, Brazil, Mexico" description: "Blockchain payments are legal for businesses in the US, EU, UK, Brazil, and Mexico, under different rules. What each country regulates, as of October 2026." date: "2026-10-02" updated: "2026-10-02" category: "compliance" author: "BlindPay Team" faq: - q: "Are blockchain payments legal for businesses?" a: "Yes, in the US, the EU, the UK, Brazil, and Mexico. None of them bans a business from paying or getting paid through stablecoins. What each regulates is the companies in the middle: stablecoin issuers, exchanges, and the providers that convert and move funds. Those need licenses or registrations, and they run KYC, AML, and sanctions checks on you." - q: "Do I need a license to use stablecoins for business payments?" a: "Usually not, if you only send and receive through a licensed provider for your own business. Licensing kicks in when you move money for other people, exchange virtual assets as a business, or hold them in custody for customers. That line differs by country, so check with counsel if your product touches other people's funds." - q: "Is it legal to pay suppliers in Mexico with stablecoins?" a: "Yes. Mexico has no stablecoin ban for businesses. The Fintech Law of 2018 governs virtual assets in financial institutions, and Banxico's Circular 4/2019 stops banks and fintech institutions from offering them to customers. Exchanging virtual assets professionally is a reportable activity under the anti-money laundering law. Most businesses pay Mexican suppliers in pesos over SPEI through a provider." - q: "How does Brazil treat stablecoin payments?" a: "Brazil regulates virtual asset providers under Law 14.478/2022 and Central Bank Resolutions 519, 520, and 521, in force since February 2, 2026. Resolution 521 treats international payments with virtual assets, and the purchase or sale of stablecoins referenced in a foreign currency, as foreign exchange operations, so they follow FX rules." - q: "When does the UK stablecoin regime start?" a: "The FCA published its final rules for stablecoin issuance in policy statement PS26/10 on June 30, 2026. The new cryptoasset regime starts on October 25, 2027, and the application window for firms opened on September 30, 2026. Until then, crypto businesses register with the FCA for anti-money laundering purposes." - q: "Does the travel rule apply to stablecoin payments?" a: "Yes, between regulated providers, with different thresholds. The EU applies it to every crypto transfer with no minimum, the US at USD 3,000 under the Bank Secrecy Act, and the UK to all transfers with less data below EUR 1,000. Brazil is phasing it in through February 2028. Your provider handles it." --- Yes. Blockchain payments are legal for businesses in the US, the EU, the UK, Brazil, and Mexico. None of these countries stops a company from paying or getting paid through stablecoins. What they regulate is the middle: stablecoin issuers, exchanges, and the providers that convert and move the money. Those firms need licenses and run KYC, AML, and sanctions checks on everyone they serve. So the practical question isn't "is it legal," it's "is my provider licensed where my money moves, and what do I still own?" This page answers it country by country.

It is general information, not legal advice. Rules change; confirm your own obligations with counsel.* ## How do the rules compare by country? | | United States | European Union | United Kingdom | Brazil | Mexico | | --- | --- | --- | --- | --- | --- | | Main framework | GENIUS Act (2025), plus FinCEN and state money transmission rules | MiCA, Regulation (EU) 2023/1114 | FSMA cryptoasset regime; AML registration with the FCA today | Law 14.478/2022 and BCB Resolutions 519, 520, 521 | Fintech Law (2018), Banxico Circular 4/2019, anti-money laundering law (LFPIORPI) | | Stablecoin issuer rules | Core rules take effect January 18, 2027 | In force since June 30, 2024 | Final rules June 2026; regime starts October 25, 2027 | Covered by the virtual asset regime | No stablecoin-specific law | | Who needs a license | Issuers; money transmitters register with FinCEN and hold state licenses | Issuers (as EMIs or banks) and crypto-asset service providers | Cryptoasset businesses register with the FCA now; authorization under the new regime | Virtual asset service providers (PSAV) | Banks and fintech institutions need Banxico approval, limited to internal operations | | Travel rule | USD 3,000 | Every transfer | Every transfer, reduced data below EUR 1,000 | Resolution 520, phased in through February 2, 2028 | No crypto travel rule; exchange activity is reportable to the UIF | | What a business using a provider does | Gives accurate KYB data, follows OFAC sanctions | Uses an authorized CASP, uses MiCA-compliant stablecoins | Uses an FCA-registered firm | Uses an authorized provider; cross-border flows follow FX rules | Pays and gets paid in pesos through a provider, usually over SPEI | The rest of the page explains each column. ## Are blockchain payments legal in the United States? Yes. The [GENIUS Act](https://www.congress.gov/bill/119th-congress/senate-bill/1582/text), signed on July 18, 2025, is the federal law for payment stablecoins. It requires issuers to be licensed, to hold 1:1 reserves in cash and short-term Treasuries, and to publish monthly reserve reports, and it bans them from paying holders interest. Its core rules take effect on January 18, 2027, and from July 18, 2028, platforms may only offer stablecoins from permitted issuers to people in the US. A business that pays and gets paid through a provider doesn't need a GENIUS license. Two other layers still apply. Companies that move money for others are money transmitters: they register with FinCEN as a money services business and hold state licenses. And every US person follows OFAC sanctions. The [GENIUS Act explained for businesses](/resources/more/genius-act-for-businesses) covers the rule-making timeline in detail. ## Are blockchain payments legal in the European Union? Yes. [MiCA](https://eur-lex.europa.eu/eli/reg/2023/1114/oj), the Markets in Crypto-Assets regulation, has applied to stablecoins since June 30, 2024 and to crypto-asset service providers since December 30, 2024. A euro or dollar stablecoin is an e-money token, which only a licensed credit institution or electronic money institution can issue. Exchanges, custodians, and transfer providers need authorization as crypto-asset service providers. The Transfer of Funds Regulation applies the travel rule to every crypto transfer between providers, with no minimum, since December 30, 2024. For a business, the practical effects are two: use an authorized provider, and expect it to offer only MiCA-compliant stablecoins. [MiCA stablecoin rules explained](/resources/more/mica-stablecoin-rules-explained) goes deeper. ## Are blockchain payments legal in the United Kingdom? Yes. Today, firms that exchange or hold cryptoassets for customers in the UK must register with the Financial Conduct Authority under the money laundering regulations, and they apply the travel rule to all transfers. A full regime is on the way. On June 30, 2026, the FCA published its [final rules for the new cryptoasset regime](https://www.fca.org.uk/publications/policy-statements/cryptoasset-regime), including policy statement PS26/10 on issuing UK stablecoins: backing assets, redemption, safeguarding, and disclosures. The application window opened on September 30, 2026 and closes on February 28, 2027, and the regime starts on October 25, 2027. The government has also proposed moving payments that use UK-issued stablecoins into a future payments regime rather than treating them as crypto trading. For businesses using a provider, the rule of thumb holds: work with an FCA-registered firm now, and ask it about its authorization plan. ## Are blockchain payments legal in Brazil? Yes. [Law 14.478/2022](https://www.planalto.gov.br/ccivil_03/_ato2019-2022/2022/lei/L14478.htm) set the legal framework for virtual asset service providers, and the Banco Central do Brasil published Resolutions 519, 520, and 521 on November 10, 2025. They took effect on February 2, 2026 and require providers serving Brazilians to be authorized as PSAVs, wherever they're based. The detail that matters for cross-border payments: Resolution 521 brings international payments and transfers with virtual assets, and the purchase or sale of stablecoins referenced in a foreign currency, inside Brazil's foreign exchange rules. A dollar stablecoin payment into Brazil is treated like an FX operation, with the reporting that comes with it. Resolution 520 also brings in the travel rule, phased in until full compliance on February 2, 2028. Pix payouts require the receiver's name and CPF or CNPJ to match the account. [PSAV in Brazil explained](/resources/more/psav-brazil-explained) covers who needs authorization. ## Are blockchain payments legal in Mexico? Yes, for businesses, with one big limit on banks. Mexico's Fintech Law of March 2018 defines virtual assets and leaves their regulation to the Banco de México. Banxico's Circular 4/2019, published on March 8, 2019, lets banks and fintech institutions use virtual assets only in internal operations, with prior approval, and not offer them to customers. Outside the banking system, exchanging virtual assets as a business is a "vulnerable activity" under the federal anti-money laundering law (LFPIORPI). Firms that do it identify their customers and report operations above set thresholds to the financial intelligence unit. A July 2025 reform lowered those thresholds and extended record-keeping to 10 years. Mexico has no stablecoin-specific law. In practice, Mexican suppliers and contractors get paid in pesos over SPEI, and the stablecoin conversion happens at a provider. ## What do you still own when you use a provider? In every country above, the provider carries most of the regulated work. Your side is short, and it doesn't go away. 1. **Give accurate onboarding data.** Company documents, beneficial owners, and the people who'll use the account. Bad data is the most common reason a payment gets held. 2. **Know what your product does with other people's money.** If you collect or pay out funds for your customers, you may need your own license. Get an opinion from counsel. 3. **Don't nest.** Register each of your customers with the provider instead of running their money through your own account. 4. **Keep a payment purpose for every transfer.** Invoices, contracts, and payroll records answer most requests for information. 5. **Follow sanctions rules yourself.** Don't pay anyone you know to be sanctioned, whatever the provider's screening says. 6. **Answer requests quickly.** A flagged payment waits on you. 7. **Keep records.** Mexico's reform now expects 10 years for reportable activities. Keep at least what your own regulator and auditor require. 8. **Re-check every year.** The UK and US regimes both change in 2027. ## How does BlindPay handle this? [BlindPay](/global-payments) is registered with FinCEN as a Money Services Business (NMLS #2745309) and publishes its license status by country on its [licenses page](/licenses). KYC, KYB, sanctions screening, and travel rule checks run inside the API before money moves, so a business using BlindPay doesn't build them from scratch. Payouts land in local currency over Pix in Brazil, SPEI in Mexico, ACH, wire, and RTP in the US, SEPA in Europe, and SWIFT (POBO/COBO) elsewhere. The customer requirements per country are in the [KYC reference](/docs/kb/kyc), and the countries BlindPay serves, by risk tier, are in the [supported countries list](/docs/kb/supported-countries). ## What to do next List the countries your money leaves from and lands in. For each one, ask your provider two questions: which license or registration covers it there, and who runs the travel rule. Then check your own product against step 2 above.
