Mercuryo: regional crypto dealing, Wallet access and payment costs

The Wallet registration pause does not say that every embedded purchase is unavailable. The buying instructions separately describe a Widget route to an external address, with email verification and payment authentication. Existing Wallet users have their own login flow. When adding a new card, the guide describes a EUR1 preauthorisation normally returned within minutes; that temporary card check is distinct from the conversion fee.[8]

A swap quote has a six-hour validity period that includes the required receipt and blockchain confirmations. The terms require one deposit, the exact asset, network and amount, and a single-use address. Even inside that period, Mercuryo reserves the ability to decline the quoted rate when market movement makes execution commercially or operationally unviable. A late or mismatched deposit may be repriced or returned, with network and permitted recovery costs deducted. Temporary handling during a swap does not create a standing wallet balance, and an output already sent cannot be recalled.[10]

The displayed exchange rate can contain a spread whose fixed size is not published. The July disclosure adds a 0.25–1% currency charge for non-EUR purchases or sales and a partner infrastructure fee, typically 0–2% and capped at 5%. The infrastructure charge is shown separately. Network costs and a customer’s own bank charges can also affect the final economics.[11]

The minimum-amount guide describes EUR25 equivalent as the usual starting point for most assets, with variation by network and payment method. At exactly EUR25, a EUR4 minimum sale fee alone would represent 16% of the amount. That is arithmetic from the published minimums, not a live quote or a claim that every EUR25 sale is permitted. Small withdrawals should therefore be compared by the fiat actually received.[13][12]

The February fee guide’s no-charge statement for receiving crypto does not make a subsequent wallet withdrawal free of blockchain costs. FastTrack is also an additional option charge, so its percentage should not be confused with the ordinary service-fee ceiling. A useful retained record includes the payment currency, crypto quantity, payment rail and final fee breakdown; these inputs explain why two checkouts can deliver different amounts without either using an order-book commission.[12]

Regular SEPA purchases require the exact EUR amount and the unique reference shown on the invoice. The instructions give the invoice a 120-hour life; a late payment can lead to cancellation and refund. The applicable exchange rate is determined when funds arrive. This matters for a transfer close to a weekend or bank holiday: initiating the payment before the deadline does not itself establish timely receipt or lock the earlier displayed crypto amount.[15]

For a sale, Mercuryo supplies a single-use crypto destination. The customer must send the stated amount, wait for the required confirmations and avoid reusing the address for a later order. The September instructions warn that wrong amounts can delay or prevent processing. Where a return address is requested, the described return-address flow does not support XRP destination tags or XLM memos. A destination needing either identifier therefore requires specific confirmation before it is used.[9]

Buying permission and sale-payout permission are distinct. The September card-payout matrix marks both Visa and Mastercard payouts unavailable in the US and in numerous EEA countries, including Germany, France, Italy, Spain and the Netherlands. It lists different availability in other markets. The sell guide also states that selling is currently unavailable in the UK. These restrictions are more useful to a prospective seller than the group’s broad international coverage figure.[18][9]

A Widget purchase sent to an external wallet and a balance held in Mercuryo Wallet have different custody arrangements. The global agreement describes MoneyMaple’s virtual-asset wallet service, whereas the US agreement says MoneyDream does not provide custody, hold private keys or recover a customer’s external wallet. The applicable contract and the selected destination should establish which arrangement exists before the customer sends funds.[2][4]

Mercuryo’s TON notice says that some deposit addresses ceased to be supported from 7 April 2026 and that affected users received replacement addresses in their profile. It warns that deposits to obsolete addresses can be permanently lost. Existing withdrawal-address books and recurring transfers at another platform therefore need attention even if the customer’s Mercuryo login remains unchanged. An old successful transaction is insufficient evidence that the same address is still usable.[22]

The same limits article states that transaction and monthly allowances include fees and that monthly usage follows a rolling period. It offers a documentation-based route to request an increased monthly buying allowance; approval is not automatic. Its EUR10,000 EEA annual cap is particularly material because a broader merchant-facing limits table can otherwise suggest substantially more capacity. The current individual-account allowance remains the relevant operational check.[16]

The integration documentation says eligibility can depend on the customer’s IP location, card-issuing country and verified residence. A customer travelling abroad can therefore face a different checkout outcome without having changed nationality. The merchant coverage guide describes more than 150 on-ramp countries and a narrower set of fiat payout currencies; those figures do not mean every asset, network and method is usable in each location.[26][17]

The complaint guide asks for the account email, a clear description, transaction information and supporting evidence. It promises acknowledgement within three working days and aims for a final response within 15 working days; complex investigations can take up to 35 working days with an update. Its Financial Ombudsman route is specifically conditional on eligibility for e-money accounts or merchant acquiring. It should not be read as an automatic external remedy for every crypto conversion.[24]

A missing item in Widget history can therefore reflect the product used, rather than a missing transaction. Preserve the receipt and blockchain hash alongside the relevant interface history when asking support to reconcile a payment. The reviewed history guide establishes viewing routes, but does not establish a universal CSV export, complete account statement or jurisdiction-specific tax report. No separate emergency telephone dealing service was identified.[23][24]

CNMV’s public provider list records Criptan Trade, S.L. as authorised from 26 June 2026 for custody, crypto-to-fiat exchange, crypto-to-crypto exchange and transfers. That is evidence about Criptan’s authorised services. It does not make Moneychurros a CASP or establish that every Mercuryo product uses every permission. The July EEA agreement expressly says Moneychurros itself does not hold MiCA CASP authorisation and requires the relevant provider to be identified before confirmation.[7][3]

Mercuryo publishes FINTRAC MSB number M21565803 for Canada’s MoneyMaple Tech Ltd. Its licensing page separately gives FCA electronic-money institution number 900921 for Monetley Ltd and agent number 850523 for Moneytea Ltd. These are service-specific disclosures, not a single group licence for crypto worldwide. The underlying current Canadian and UK register conditions were not independently established for this profile.[5]

The US agreement explicitly describes MoneyDream LLC as an unlicensed facilitator relying on third-party providers for regulated services. It also says the relevant crypto and fiat are not protected by FDIC, SIPC or another government protection scheme. No customer-level private insurance entitlement was established. A claim about technical security should therefore be assessed separately from a claim that a loss is insured.[4]

The current website claims more than 12 million KYC-verified users and integrations with more than 500 Web3 businesses. Those are company-reported reach measures, not verified monthly active traders or audited spot-exchange turnover. Mercuryo dates its business to 2018. Its scale is best understood here as distribution through wallet and application integrations rather than as an order-book liquidity ranking.[1]

The processing help page says the operating entity is selected automatically and shown before checkout and in transaction records. It uses “MoneyDream Inc.” for the US, while the current US agreement names “MoneyDream LLC”. This corporate-form discrepancy remains unresolved in the public documents; the entity and regulated provider shown in the applicable checkout and contract should be retained with the receipt.[6][4]

Boost Points are governed by separate terms updated on 11 September 2026. They are virtual, non-monetary rewards with redemption governed by the displayed programme and any additional conditions. They are generally personal and non-transferable; cancelled or refunded transactions can remove eligibility, and expiry does not require compensation. Points should therefore not be described as an unconditional withdrawable cash balance or a guaranteed fee rebate.[25]

Merchant integration documentation distinguishes a Widget ID and secret from the partner token used for silent authentication and API-based verification. These credentials enable an application workflow; the public FAQ does not establish unrestricted access to all of a retail customer’s balances or universal withdrawal authority. The application’s own permissions and the specific operation still matter when assessing what has actually been authorised.[26]

The transaction-history interface recognises recurring purchases separately from regular purchases. This helps a customer identify continuing instructions when reviewing activity. The reviewed record-viewing guide does not itself explain a universal cancellation or migration rule for every partner’s recurring arrangement. The partner and the Mercuryo account should therefore be checked together when a recurring purchase continues after an application change.[23]
