Question 1

What cryptocurrencies do you accept?

Accepted Answer

We accept over 100 cryptocurrencies including Bitcoin, Ethereum, USDT, USDC, BNB, Litecoin, and many others. You can choose your preferred cryptocurrency at the moment of payment.

Question 2

Are eIDAS Qualified Electronic Signatures (QES) legally binding?

Accepted Answer

Yes. Under EU Regulation 910/2014 (eIDAS), a Qualified Electronic Signature has the same legal effect as a handwritten signature and is admissible as evidence in all EU member states. Mercury Evidentia provides QES through its qualified signature provider, with the qualified certificate issued by a Qualified Trust Service Provider (QTSP) and identity verification where available.

Question 3

Is Mercury Evidentia GDPR compliant and SOC 2 ready?

Accepted Answer

Yes. Mercury Evidentia is GDPR compliant with EU data residency, data processing agreements, and full data-subject rights. Our infrastructure is SOC 2-aligned with AES-256 encryption at rest, audit logging, and tenant isolation. Compliance documentation is available to Professional and Enterprise customers.

Question 4

Is blockchain notarization legally valid as proof of integrity?

Accepted Answer

Blockchain notarization anchors a cryptographic hash of your document on the Polygon network, creating a tamper-evident, timestamped record. While not a substitute for a notary public, it provides court-admissible technical proof that a document existed in a specific state at a specific time and has not been altered since.

Question 5

How does the Dead Man's Switch work?

Accepted Answer

The Dead Man's Switch lets you set a check-in interval. If you don't confirm you're active within that period, Mercury Evidentia automatically releases designated documents to your chosen beneficiaries — useful for estate planning, succession, and emergency access. You stay in full control and can pause or reconfigure it at any time.
