📝 Do You Need a Legal Opinion for a Crypto Exchange?

🏛 Evolving Legal Frameworks

In the UK, the Financial Services and Markets Act 2023 (FSMA 2023) granted HM Treasury the power to regulate cryptoasset activities. Key measures are being phased in, with particular focus on fiat-backed stablecoins. Firms dealing in crypto promotions to UK clients must already comply with the FCA’s financial promotion regime, which requires clear, fair and not misleading communications. However, much of the detailed framework is still under consultation and not yet fully in force.

In the EU, the Markets in Crypto-Assets Regulation (MiCA) became law in June 2023, with staggered application dates. Since 30 June 2024, rules on stablecoins (asset-referenced and e-money tokens) apply. From 30 December 2024, most obligations for Crypto-Asset Service Providers (CASPs) are in effect. Transitional periods exist in some Member States, but new providers need MiCA authorisation.

In the US, the regime remains fragmented. The SEC, CFTC, and FinCEN may all claim jurisdiction depending on the token’s classification and services offered. State licensing (e.g. money transmitter licenses) further complicates compliance.

⚖️ Why a Legal Opinion Matter

A legal opinion is not just a formality - it’s a compliance safeguard. It analyses:

The type of token: utility, security, or stablecoin.

Jurisdictions of operation: where customers are located and where services are offered.

Nature of services: custody, exchange, staking, wallet provision, etc.

Advertising and promotions: whether communications comply with FCA or ESMA rules.

AML/KYC obligations: mandatory under EU AMLD, UK MLRs, and FinCEN in the US.

For example, under MiCA, CASPs must meet governance and transparency standards, maintain adequate reserves (if issuing stablecoins), and hold an EU license. In the UK, firms promoting crypto to retail investors must register and comply with FCA oversight. In the US, token projects must carefully analyse whether they fall under the Howey Test for securities.

Without a legal opinion, firms risk enforcement actions, reputational damage, and barriers to raising capital.

📚 Practical Cases & Applications

UK Stablecoin Issuers: Since mid-2024, authorisation is required to issue fiat-backed stablecoins in the UK. Exchanges supporting such tokens need a legal opinion to confirm whether they are in scope.

MiCA Transition in the EU: Existing firms with national authorisations may continue temporarily, but must align with MiCA standards before transition periods expire. A legal opinion ensures correct timing and compliance strategy.

Cross-border Services: Offering exchange services from one country to clients in another may trigger licensing there. For example, a UK-based exchange marketing in Germany could face MiCA requirements.

Promotions Enforcement: The FCA has already taken action against misleading crypto promotions. A legal opinion can provide the legal backing for compliant marketing materials.

Securities Classification: US case law continues to test token classification. Projects structured as “utility tokens” have been re-classified as securities, showing the need for early legal assessment.

✅ Conclusion

Crypto exchanges and token projects operate in one of the most dynamic regulatory environments worldwide. With the UK FSMA 2023 phasing in new rules, the EU MiCA framework now active, and US agencies enforcing existing laws, obtaining a legal opinion is no longer optional – it is a strategic necessity.
