At 20:19 UTC on October 9, 2026, Coinbase Developer Platform announced that Coinbase and Gennius would bring ONED USD to Latin American banks, starting in Argentina. ONED USD is backed 1:1 by $USDC. The planned service covers stablecoin payments, custody and trading from a banking app.
Coinbase described a direct conversion route from eligible bank deposits into ONED USD. Customers would be able to transfer the stablecoin around the clock and spend through Visa. The announcement does not identify an Argentine bank, give a launch date, name a supported chain or state the fees and redemption terms. Those details determine whether the service works as a bank-integrated dollar balance or as a separate crypto product reached through the bank’s interface.
The October announcement extends a product that Gennius launched on June 15, 2026. The launch release describes ONED USD as a stablecoin for rewards, payments and digital assets across banks and financial technology partners. Gennius said the token is powered by Coinbase and fully backed by $USDC. Coinbase described it the following day as live and built to connect rewards, payments and digital assets across global banking partners.
How the bank route is meant to work
The user-facing sequence in Coinbase’s announcement has three steps. A customer starts with an eligible deposit at a participating bank, converts it into ONED USD, then transfers it at any time or spends it through Visa. Custody and trading sit in the same banking-app proposition. Coinbase did not say whether the bank, Gennius or Coinbase would face the customer for each function. It also did not say whether Visa purchases would settle from ONED USD directly or convert into another balance before authorization.
Gennius built ONED USD for a broader pool of balances than bank deposits. Its launch release names loyalty points, cashback balances, merchant credits and stored value as examples of value held in separate systems. The company says banks, fintech companies, wallets and buy-now-pay-later providers can use ONED USD to turn loyalty liabilities into programmable assets. A wallet can combine rewards, fiat balances and digital assets behind one interface. The original issuer remains responsible for backing tokenized points, miles, cash deposits and digital assets while Gennius provides the liquidity and programming layer described in the release.
That structure matters for depositors. The latest announcement says only eligible deposits can be converted. It does not define eligibility or say whether a conversion changes the customer’s legal claim from a bank deposit into a stablecoin claim. The June release says original issuers continue to back the underlying balances, while ONED USD itself is backed by $USDC. Participating banks will need to explain which entity owes redemption, how the two backing statements interact and what happens when a customer moves ONED USD out of the bank app.
The distinction also matters for round-the-clock transfers. Continuous token movement does not by itself establish continuous bank redemption. Coinbase promises transfers 24 hours a day, seven days a week, but its announcement gives no cut-off rules for moving between a deposit and ONED USD. Operators will need the supported network, confirmation policy, withdrawal controls and reconciliation process before they can assess settlement risk. None of those implementation details appears in the announcement.
What operators need to establish
The product description joins two balance models. The October flow begins with an eligible bank deposit. The June release also covers rewards, cashback, merchant credits and stored value, with each original issuer continuing to back its own balance. A participating bank therefore needs to show customers which balance they hold before and after each conversion. It also needs to distinguish ONED USD custody from the bank account shown beside it.
The same separation applies to spending. Visa access tells customers where they can use the balance, while the announcement leaves the conversion path unstated. The operator must disclose whether ONED USD is redeemed before a card payment, who sets the conversion rate and which party handles a failed or reversed purchase. Coinbase’s reference to custody and trading also leaves open whether those functions share the same terms as deposit conversion.
For rewards operators, the launch release presents ONED USD as a common liquidity layer across points, fiat and digital assets. The original issuer backing statement means those source balances do not automatically become Coinbase liabilities. Programs considering the system need to identify the issuer for each balance, the route into ONED USD and the redemption route back to the original program.
The existing ONED network
Gennius reported in June that it supported more than 83 banking and financial-institution partners, with deployments in Latin America and the CEMEA region. It also reported more than 500 rewards programs and more than 18 billion tokens issued through its platform during the preceding year. The same release’s company description says Gennius supports more than 70 banking and financial-institution partners. The document does not reconcile the two partner counts, so neither figure establishes how many institutions will offer ONED USD.
The scale of $USDC provides context for the backing asset. At research time, the DefiLlama stablecoin API returned circulating $USDC of about $73.0 billion across 157 chains. ONED USD is therefore a branded access layer over a much larger reserve asset, according to the companies’ description, rather than a separately disclosed reserve portfolio. The announcement does not provide ONED USD supply, reserves, attestations or a contract address.
Gennius framed the initial use case around a large pool of closed balances. Its launch release puts global issued loyalty and rewards value above $1 trillion. Group CEO Ruben Salazar Genovez said ONED USD was intended to convert fragmented balances into programmable digital value. Coinbase infrastructure head Alec Lovett said the work brings $USDC liquidity and Coinbase infrastructure into sectors where value had been fragmented. These are company descriptions of the opportunity, not measures of deposits committed to the Argentine rollout.
For users, the practical attraction is access through an existing bank relationship, with deposit conversion, continuous transfers and Visa spending in one interface. The main unanswered questions concern the named bank partners, rollout date, conversion and redemption fees, supported chain, custody terms and treatment of deposit protections after conversion. Coinbase and Gennius have not dated the Argentine launch or identified the first participating bank.
