Thunes: cross-border payments, collections and treasury infrastructure

Thunes supplies cross-border payment infrastructure to banks, payment companies, mobile wallets, digital-asset firms and other businesses. Its Direct Global Network joins local payment systems through common connectivity. Pay handles outbound transfers; Accept handles incoming payments. These are operational payment services around a customer relationship, rather than an FX trading venue or broker execution platform.[1]

SmartX Treasury supports liquidity management and payment FX. Thunes describes visibility of payout prices, conversion fees and the amount the beneficiary receives. The associated Fortress Compliance branding concerns controls embedded in the payment network; it does not establish permission for a broker’s underlying investment activity.[2]

Money Transfer callbacks contain a JSON transaction object. The listener acknowledges HTTP 2xx; failed delivery is retried several times, after which the sender must query status. The documentation gives no universal retry count or interval.[6]

Accept distinguishes authorisation from charging. Its documented charge operation supports full or partial amounts, and refund operations require a refundable method and a charged amount. A partially refunded order returns to Charged; Refunded means the entire charged amount has been returned.[7]

Network rules add a practical checkout constraint: methods using an external destination require a full-page redirect, with the final URL and TLS certificate displayed; an iframe is prohibited. Recurring payments require the customer’s authorisation and any notices required by that method.[8]

Swift is another connection path for financial institutions. Thunes’ February 2026 announcement identifies Banco Cathay of Costa Rica as an activated Pay-to-Wallet customer using existing Swift connectivity.[25]

Charges are agreed through the order or onboarding and exclude VAT/sales taxes. A signed service agreement can override the July 2026 standard terms.[9]

The UK and EU card-processing supplements request blended merchant charges across card brands and categories. A customer can ask for unblended rates; transaction and charge information may be supplied as monthly aggregates by brand, application, category and interchange rate. These provisions describe the charging structure, not a published numerical acquiring tariff.[12][11]

Network Partner Terms tie transaction fees to the payment method and Order Document. Settlement timing also depends on the method and can be delayed by the partner. Refunds use the original method; some support only full refunds, and some support none. These constraints affect how a broker can return money even when its own ledger supports a partial withdrawal.[8]

Thunes advertises a testing environment, modular integration, site-to-site VPN or HTTPS, and transaction monitoring/reporting. The public integration page gives no standard number of days to launch. Deployment involves the relevant payment routes and operational reporting as well as the transport connection.[17]

Accept credentials are issued through the Portal after initial compliance review. Its production and sandbox endpoints are provided on account creation; HTTPS requires TLS 1.2 or later. Basic Authentication uses an API key and secret, which the guide says to keep outside source code and version control.[7]

Money Transfer’s preproduction simulator changes transaction states but cannot simulate Created or Confirmed. Transactions are created and confirmed through their normal APIs before later states are simulated. This supports testing rejection and completion paths without treating a simulated status as a live payment.[6]

Enabling a payment method depends on the account type, region and eligibility. Network partners may require evidence in a dispute, and excessive fraud or unresolved disputes can suspend that method. A method can therefore become unavailable while other parts of the integration remain usable.[8]

The technical-integration page advertises worldwide support around the clock, including troubleshooting. It does not publish severity-based response or restoration targets. Separately, the contact page limits the published US customer-service telephone hours to 07:00–17:00 Pacific Time; those hours should not be substituted for the global technical-support description.[17][18]

The current restricted list specifically includes retail trading such as CFDs, as well as financial services and upstream/nested payment flows. These require Thunes’ written approval and enhanced due diligence. Unlicensed FX brokers sit in the prohibited category where licensing is required. A payment licence or a working API connection does not override that business-eligibility policy.[14]

The order identifies the supplying entity and services. The MAS entry is an independent register check; the other rows reproduce the provider’s current contracting disclosures.[15][16]

Singapore’s supplement describes a trust account for Relevant Money within the Payment Services Act definition. Customer money is separate from Thunes’ own money but pooled with other customers’ money. The terms expressly identify possible shortfalls, competing claims and recovery delays if Thunes or the safeguarding institution becomes insolvent. Interest is retained by Thunes.[13]

The cross-border payments business began in 2016 and adopted the Thunes name in February 2019 when it separated operationally from DT One’s mobile-top-up and rewards business. TransferTo is therefore part of its history, while the UK contracting company retains TransferTo in its legal name.[20]

Limonetik became Thunes Collections following the 2021 acquisition, adding payment-acceptance capabilities to outbound transfers. That history explains the Collections name still encountered in the documentation.[21]

Thunes announced a USD 150 million Series D led by Apis Partners and Vitruvian Partners in April 2025. Its current leadership page lists Peter De Caluwe as Deputy Chairman and CEO, and Chloé Mayenobe as Deputy CEO.[22][23]

The June 2025 US announcement describes direct contracting with American businesses and local funding through Thunes Financial Services, LLC.[24]

On 19 October 2026, Thunes and Coinbase announced a collaboration under which Coinbase will integrate the Thunes network for fiat payouts and supply stablecoin infrastructure to Thunes. The release describes integration to come; it does not confirm activation of every new route.[26]

The agreement treats Thunes and its customer as independent controllers and permits deidentified/aggregated transaction data in machine-learning training.[9]

The privacy notice says significant decisions always involve human intervention. Individuals can request access, correction, deletion or an electronic copy subject to applicable law. It promises acknowledgement of privacy complaints within 30 days, not completion of every erasure request within that period.[19]

After termination, funds may remain withheld for actual or reasonably expected liabilities. Continued data retention is required only by law, post-termination duties or written agreement.[9]
