OneKey Payments Review

Regional Breakdown

In Brazil OneKey covers the whole country through Pix and bank transfers at the major banks. A .bet.br operator takes deposits on Pix and pays players from the licensed institution itself.

In Mexico SPEI and OXXO cash vouchers carry the deposits, and OneKey also runs third-party payment validation on Mexican payments. It has no betting client in Mexico.

In Chile Webpay (Transbank) and local bank transfer carry the deposits. OneKey has no betting client in Chile either.

Colombia is the furthest along of the three new markets, and OneKey belongs to Colombia Fintech there. PSE, Nequi and Bre-B carry the deposits.

Verticals

Sports betting has been OneKey's core vertical since 2019, and it sells directly to casinos, sportsbook platforms and fantasy sport operators. Its betting clients all hold .bet.br licenses, and at BiS SiGMA 2024 it urged operators to use only regulated payment providers. Its KYC checks and cash-out controls follow Brazil's betting rules, which makes OneKey a processor for licensed books and no way around the .bet.br license. OneKey also markets its betting product in Chile, where online betting is unregulated, and in Ecuador, where sports betting has been regulated since July 2025 and online casino is illegal. Outside gambling OneKey serves e-commerce, fintech, remittance and travel merchants, which its FX desk, BaaS accounts and CianoPay card processing are aimed at.

Pix deposits through OneKey land instantly, 24/7, weekends included, and OneKey converts above 90% of them. Biometric Pix and Open Finance ITP leave that timing alone and remove the app switch between the QR code and the confirmed payment, so fewer players abandon a deposit. Payouts leave OneKey by bank transfer in under 2 hours, 24/7, and mass payouts run in real-time and batch modes on its own infrastructure. The payout path does not wait on a partner bank's batch, because OneKey is itself the e-money institution holding bettor funds and a direct Pix participant. Pay4Fun, which also holds its own BCB e-money license, pays out instantly via Pix, so a OneKey player can wait up to 2 hours longer. D24 pays bank transfers in under 2 hours, 7 days a week, so a player waits the same at either processor. OneKey settles merchants in BRL by default, and a merchant collecting across Latin America can take settlement in USD or stablecoins instead.

Integration Assessment

OneKey integrates through one REST API, documented at apidocs.onekeypayments.com, that covers deposits and payouts, with a method page per country and sandbox and test flags per method. Biometric Pix cannot be tested in the sandbox. A Java SDK comes as a direct download, and there is no mobile SDK, so the integration runs server to server. Atlaslive is the one casino-platform connector, live in Brazil since September 2025, and its extension to the rest of Latin America is announced and not live. Operators on SoftSwiss, EveryMatrix or other platforms build against the REST API directly. OneKey runs its own card checkout next to the API-driven Pix flows and gives each merchant a dedicated account manager, though not an iGaming-specific team.

Compliance Context

The Central Bank authorization makes OneKey the legal settlement entity for bettor funds, and it segregates them between transactional and proprietary accounts. QuickPay, the machine-learning KYC OneKey launched for betting in 2023, runs fully automated: it validates each CPF, blocks minors and flags politically exposed persons, athletes and social-program beneficiaries, the groups Brazil's betting rules exclude. Velocity Check applies real-time transaction rules next to Pix key validation, and OneKey registers up to three cash-out accounts per bettor automatically. Pix has no chargeback mechanism, while on card payments the merchant carries chargeback liability. OneKey holds no PCI DSS Level 1 attestation, ISO 27001 or SOC 2, which matters once an operator routes debit cards through it.

Regulatory Position

OneKey Payments Instituição de Pagamento S.A. holds an active Central Bank of Brazil authorization as a payment institution and e-money issuer (EMEL), published in the Diário Oficial da União on March 11, 2024. Under Law 14.790 only institutions authorized by the Central Bank of Brazil may intermediate bettor payments, and OneKey holds that authorization in its own name, so the operator contracts with the licensed institution itself instead of a gateway working under a sponsor bank's license. Since December 20, 2024 it has also settled Pix as a direct participant on its own account. OneKey holds no CNBV license in Mexico and no payment license in Chile or Colombia. On the industry side it has been an IBJR associate since January 2024, an ABRACAM member covering its foreign-exchange business since July 2024 and a founding signatory of the IBIA Payment Provider Forum since February 2025. Control runs through the UK. The London holding Moovefin Holdings Ltd has sat above the Brazilian entity since September 2022, and Spanish national Emiliano Sebastián Fernández has held 75%+ of its ownership and voting rights since October 2024. The Central Bank classifies OneKey as controlled by a foreign group, and César Garcia runs the company as CEO. The chain disqualifies nothing, but a compliance team's counterparty file on OneKey ends with one Spanish owner behind a London holding.

Named iGaming Clients

BandBet, Alfa (alfa.bet.br), Bet do Milhão (TQJ)

BandBet, the Grupo Bandeirantes betting brand built with Bell Ventures Digital on OpenBet, made OneKey its official processor for Pix pay-ins and payouts in October 2024. Alfa Entretenimento's alfa.bet.br, one of the first fifteen definitive .bet.br licensees, signed in May 2025, and OneKey runs its payment flows, biometric Pix included. TQJ (Todos Querem Jogar), the Grupo Silvio Santos company behind Bet do Milhão, signed in August 2025 to process its payments under SPA rules. Internacional ended its Alfa sponsorship on January 11, 2026 over three missed R$4.16 million installments. OneKey is the processor of record on its clients' Pix transactions, so its name shows on bettors' bank statements, and it serves 170+ clients across all its verticals.
